  1. I like the fact that my 6.2 has lots of power and actually does get good gas mileage. I can run 65/70 and easily get 23-25mpg. I’m about to upgrade tires and looking for recommendations. I know I’ll lose some mpg and possibly low end power, but I don’t want to turn my beast of a truck into a turd. I currently have stock 275/55r20 (31.9x10.8) on stock “snowflake” rims with Bilstein 2” strut/shock upgrade. 3 tire sizes I’m interested in: 275/60r20 (33x10.8) 285/55r20 (32.3x11.2) 295/55r20 (32.8x11.6) If I had my way, I’d throw a 305/55r20 on there but I know I’d kill my power. I know this because I have 295/55r18 on my Ford and I ended up doing a gear swap from .373 to .456 to bet my power back. I’m in the real estate business. I buy and sell farm and recreational land so I put lots of hwy miles on this GMC yet still need a tire to get me in and out of places on the farm and pull a tractor when I need to. I have trucks to mudbogg in, looking for practicality here. Really hoping to to hear from guys with 6.2s. Thanks in advance.
  2. Looking for some tire recommendations for my 2018 Z71 Silverado 4x4. I currently have a Moro fab lift (3” in the front and 2” in the rear) and am looking to run 33’s. Anyone running 275/70r18’s or 285/70/r18’s or 285/75/r18’s? Drop pictures and recommendations if you have them. Looking to keep my stick 18” rims.
  3. A flat Good Year Wrangler SR-A set the tire shopping in motion, and a 10% off sale on Nittos convinced me to try the 35x11.50r20 Ridge Grapplers. My goal was to get as much tire as possible without having to adjust the suspension so as to retain the stock ride, keep costs down, and achieve the aesthetic I like for modern 4x4 trucks. I was prepared to crank the front keys a few turns for up to 1" of leveling, but my preference was to avoid this if possible. Ridge grapplers have two sidewall designs on the tire; one side reminded me of Transformers, so I went with the more subdued sidewall. This doesn't impact fitment. After about 20 miles of driving and some parking lot testing turning the steering back and forth, the tires fit fine with only a few close spots throughout the range of motion. I've seen people report frame rub at full lock with these sizes; it hasn't happened to my truck yet, but I wouldn't be surprised if it rubs mildly while turning sharply over rough terrain. Rear clearance is fine. A few tips: Check the actual dimensions of the tire you're choosing. The Nittos are 35s, but the actual diameter is about 34.7". Each manufacturer is a little different, and most list the true dimensions on their websites. The same applies to metric sizes - a BFG may be narrower than a Toyo. Looking at my truck, 35x12.50r20 would have fit too, but would probably rub on the wheel wells while going over bumps during a turn. The 11.50s provide just enough extra room that my truck has yet to rub, though my mileage count is low (20 miles since install) so I'll update this thread as I add miles. Expect to lose fuel economy. No data yet, but I anticipate a 1-2 MPG drop. Aftermarket wheels change everything. The popular offset or "poking" look makes it harder to stuff big tires without a lift. If you're changing wheels and tires, disregard this thread. What's next? Fresh oil, a detail, and maybe a front window tint. I'd like a Corsa, but they're $$$. Please excuse the dirty truck:
  4. Anyone have experience fitting 22” wheels and tires on a stock canyon Denali? Not sure if I need to lift it at all first. Thanks
  5. Hi guys, Over the winter i bought some 33"tires (275/60R20) to go along my 2016 Sierra Elevation.. this truck has a 5.3L and 3.42 gears ...during summer time i usually pull my TT that weights 6350lbs dry so knowing myself it is usually at 7500lbs full so lets make it 8000lbs for worst case scenarios ... I have a 6L-80 Trans 6 Speed ... So my question is; will it be that much of a power loss with the 33's on ... I mean this truck can pull 9200lbs as per the dealer specs .. but that is on the dealer tires i had last summer ...i didnt even think about the loss of power it may cause ... But i had so much of a deal on the BFG KO2 tires ... I couldnt pass on ... Now im uncertain of what i have done as the tires and installed on my rims and just waiting to bolted on ... Thanks for your help !
  6. Information on Vibration Analysis and Diagnostic 2014/2015 Chevrolet Silverado and GMC Sierra This seems to be a vibration campaign that has been around since January 2015. I have seen many complaints on different forums about this issue. I also have a vibration/harmonics issue that is not there all of the time but most. My issue seems to be centered around the V4 decel, and body mount configuration. This link is filled with a ton of information about various causes and repairs many of the 2014/2015 GM truck owners are experiencing. Some may be experiencing a combination of more than one issue at a time. Many more may not be experiencing any vibration at all. I do believe for those folks with the "Cadillac ride" its only a matter of time before they start experiencing vibration/harmonics issues. Its kinda nice to get this information out so that GM can streamline the repair process even further. If enough of these trucks show up for repair request for vibration they may even send out letters to further enhance quality control. http://oemdtc.com/6392/information-on-vibration-analysis-and-diagnostic-2014-2015-chevrolet-silverado-gmc-sierra/3 If link does not work copy and past in your browser.
  7. Selling some tps out of my 2015 Silverado. $60 shipped within the 48 states.
  8. I was just curious if anyone had any recommendations or outlooks on leveling and bigger tires. I saw someone running a 2.5” level with 305/55/20 BF Goodrich KO2’s. Was thinking about heading down the same path. Hoping I can get a level with some 33’s with no trimming. Has anyone else done this setup or have any recommendations or pictures? Also how are the rides with a level? I have heard they get stiffer once leveled.
  9. Looking to get another wheel and tire set up. So I’m selling my 24in reps. They have about 12-13k miles on them. Been on the truck for a little over a year. Have plenty tread left. No curb damage, and wheels are properly maintained. Asking 1800.00 OBO. Included; TPM sensors, lug bolts and wheel locks, black center caps, and chrome center caps. Feel free to message me with any question. I’m in Destin, Fl. Will consider traveling within reason. Could possibly ship at buyers expense. Thanks
  10. Zone Lift

    There is probably already a thread for this but I could not find exactly what I was looking for. I am thinking about installing a 3.5"-4.5" Zone lift on my 2016 GMC Sierra All Terrain. I was wondering if anyone else has done this already and has pictures or their setup so I can get an idea. Also a link of where you bought it. I saw a lot of people said a 33" tire looks small and to run a 35", any opinions?
  11. Hello all, came up with a combo to replace stock wheels and trying to see if it'll work out and if I am thinking about the fitment correctly. Truck in question is a 2019 GMC 3500 SRW Denali - completely stock and I'd like to see if I can run 305/55-20s without having to add a lift or level Stock wheels: 18in x 8in +44 (I think) Stock tires: 265/70-18 I was looking at maybe going with XD822 Monster II 20x9 +18 with 305/55-20 tire mounted So the new rim is 1 inch wider but given offset is less +18 vs +44 by almost exactly 1 inch the inner aspect of the rim and tire will be the same as stock. Just the tire will stick out 1 inch further to the outside. The stock tire should be 32.6" tall given its sizing. The 305/55-20 would run 0.6" taller at 33.2" height. Sidewall will be 0.7in shorter on new tires and rim would clearly be 2 in taller. In the stock setup there appears to have plenty to clearance and I'm speculating it could accommodate the 0.6 inch increase in size without difficulty and the width would only be increased outward so shouldn't impact the fit. Think this would work? Has anyone tired anything like this? Poking around on here it looks like most people add at least a level kit prior to tires.
  12. I am new to this GM-Forums stuff, so what better way to get things started than to ask for some help! Im the owner of a 2016 GMC Denali 2500 HD and Ive been in search of finding the perfect setup for wheels and tires/lift. Ive been all over the internet looking for a setup, and ive finally found this one that I believe is the most bad-aslkdjf setup out there. WHAT IS ON THIS TRUCK!! I know its the FUEL TITAN D588 wheels with Toyo open country 35x12.50 R20 tires. This is just a cars salesman going through the truck and reading off what he can see... My question is; What wheel size is on this truck? Does anyone know and/or is able to figure out? Is this a 2" lift/leveling kit? Is that all this is? Will the 35" tires fit with just that minor trimming? Can you still tow with a setup like this? Hopefully someone knows as this is a killer setup!! https://youtu.be/a9Z9IMyzdp4
  13. Hi all, I just bought a new truck but the tires were shot. I looked at the tires and they are 35x12.5x18 with the stock GM rims. I called Discount Tire and they said they won't put these tires on these rims... What gives? Did the previous owner put the wrong tires on these rims? Is it unsafe? Thank you, Scott
  14. I have 57k on my factory LS2s, and they're getting a little worn. Trying to decide whether to go with another set of these, or something else. I've had a good experience with the LS2s, no shaking or anything like that. I could probably get 60k+ out of them, but I'm thinking about replacing them while GM is offering price match and $200 rebate. Looking at either another set of LS2s, Continental CrossContact LX20s, or Hankook Ventus STs. What do you guys think? Truck is a street queen and it doesn't snow down here. Just looking for a smooth and quiet ride, long life, and max MPG.
  15. So I have a 2018 Silverado 5.3 Z71 LT and I've tried looking up threads for this topic before but for some reason I haven't had any luck. Ive had this truck for a year now and I had a level lift installed and my MPG stayed around 18-22 MPG and I could get 325-400 miles out of a full tank of fuel. I recently installed a 3.5 Rough Country suspension lift and I installed 20" wheels with 33" tires. I knew going into this modification that I would see a slight decrease in MPG but immediately after the install I dropped my MPG to 7.5-9 MPG and I cannot get it to increase AT ALL. I used to work at a GM dealership and spoke to a couple of old co-workers about this issue and for some reason we cannot pinpoint the issue. I know that increasing the ride height and the different wheel/tire package would create a difference but I didn't know that it would be this bad. I'm considering a performance chip and a CAI to try and increase my MPG, and its not a bad batch of gasoline and I've changed my driving habits and kept my foot off the throttle a little bit...if anyone has any info on this it would be greatly appreciated, thanks a lot!!
  16. So what's the biggest tire we can run on a leveled Silverado with aftermarket rims that will stay flush with the fender or tucked a bit? I'm looking at some black rhinos or methods that run 18x8.5-9 with either 0 offset or +12. I'm hoping to get some 285/75-R18 all terrains to fit. I'd rather buy online as it's cheaper than the local wheel shops
  17. Hello everyone, My new to me GMC Sierra 5.3 4x4 came to me with Toyo Open Country Extreme 2 tires on it that are the following size. 285/55-20 The truck tire spec is for 275/55-20. This truck has no lift and they rub a bit in the turns. How much could this be affecting my MPG? Would it be worth putting on Highway tires since that is where I spend 99.8 percent of the time? It seems these tires would have more rolling resistance than the correct size/HT instead of larger ATs. I took a 300 mile trip and saw 14.6 one way and 17.4 back. This seems low to me so I wanted to bring this up. My Toyo's are in great shape with very little wear so I could easily sell them. What to do...?
  18. Need skme help here. I have a 16 Silverado 1500 lt with the stock 17"wheels and 255/70r17 tires. Without a lift, or a level or anything. Can I upgrade to 18inch wheels and a set of bfg all terrain 275/70r18 without any trouble??
  19. I have an age old question for everybody. I have a 2015 Silverado w/Z71 package currently running on stock 18's. I want to upgrade to bigger wheels and tires preferably 22's or 24's. I know the biggest stock setup is 22's. My question is for anyone that has upgraded to 24's or just knows from general knowledge, if i go with 24's will I have to upgrade things like calibers, rotors, recalibrate my speedometer or anything else that i'll have to do by choosing 24's. I've heard so much i decided to ask in the forum to see if anybody can share their experiences/knowledge. I don't have any lifts not even a level kit yet but I plan on getting the level done soon as well in the front. From everything I've read i know 24's will fit i'm just concerned about any additional parts/maintenance they would require. Thanks!
  20. I have a 2015 z71 cc with the 18 inch factory GoodYear SRA tires. I have 55,000 miles on these tires. They look like they have at least 10,000 more miles left. What's the average miles everyone is getting out of them before replacing them? I was also thinking about replacing them with a 275, will this hurt my gas mileage? Thanks
  21. Looking for the best online deal on wheels or even a wheel/tire package. Not sure where to look as this would be my first time making a wheel purchase online. Just purchased a 3.5" kit from rough country as well so I am open to ideas on size and offset. First time posting on this website but from what I've seen so far you guys can be very helpful!!
  22. Hello all, I just purchased a 2017 GMC crew cab 4x4. I have had 7 F150's and finally nbit the bullet and went with this beauty! I do not want to lift it as to not void the warranty so I am just going to put a 2.5 inch leveling kit on the front. It currently has 275/55/20's on it. I am going with an all terrain tire on it and am keeping the factory rims for now. I will eventually get something with an offset so the tires will stick out from the fender well around an inch or so. So, with all that being said, what it the largest size tire I can go with right now without having to worry about rubbing issues? Can I do a 33x12.50x20?
  23. $1200 Just took these off to get the black edition 22s. Tires have 80% tread left, they are continental crosscontact lx20 275/55r20 Wheels are OEM chrome 20 inch denali wheels. No blemishes or curb rash, they are perfect. TPMS not included. Located in South Florida but am willing to ship at buyers expense.
  24. Wheel Size ? ? ?

    I purchased a 2014 Silverado LTZ in April of last year. Done a few things like exhaust and an ARE Fiberglass Cap along with a Rough Country Leveling Kits spacers in front only. Unfortunately the LTZ comes with 20" wheels and I would like to know the largest size tire I can put on this vehicle. I was thinking of taking the 20's off and putting 18" wheels and tires on because there is more tire to see. I feel the 20's look like low profile when it comes to the look of the wheel. If I do so will this change anything with my computer because I changed wheel size? ? ? ? Any suggestions GREATLY Appreciated, Anthony
  25. Just bought a 2014 sierra 4x4 and ordered the 2" kit to level it out. On rough country's website they say that this kit only allows for up to a 32" tire, and I am looking to put 33s. I am new to GM, what's the biggest tires that I can fit?
