So i put my RC 2" level kit and Toyo 295/55/20's on this weekend. Install was simple, just like on my 2011. It definitely helps to have an extra set of hands when wedging that spacer in there. 295/

Thanks. Here is one more from yesterday. Considering we're getting 8-10 inches of rain the next two days, I won't be taking any better pics soon.

Mine is finally done! After months of research I went with the RC 2.5" level kit front only, stock rear block. 20"x9" Fuel Nutz w/ +1 offset, 33x12.50x20 Toyo M/T tires. No rubbing, No trimming, yet a

I ordered the 3/4" spacers (should yield close to 1-1/2" lift in the front) today. I am like many of my compatriots in here where we appreciate a nice rake on the vehicle. :D Completely leveled trucks looks cool, but I prefer achieving that with a load in the cargo bed or while towing a vehicle. This website rocks!

I just removed a Readylift Leveling kit front and rear 2.25" kit to install a BDS 4" kit. Any reason I shouldn't sell them on Ebay? Is it safe to sell someone a used leveling kit with less than 5k miles and a year installed?

I don't see why not. As long as the item isn't damaged and is still in good working condition then all you have to do is label it as "used". Only thing is you may have a few people asking why you took it off but that's it. Should sell without much issue.

Hi all,

 

I'm running the stock Chrome 20"s with crappy Good Year LS2 275/55/20 tires. I also have a 2.25" ReadyLift level. I want to swap my tires out but keep hearing different advice about how big I can safely go. Two different guys at the tire shop told me two different things. One guy said I could run all the way up to a 305/55/20...the other guy said 275/60/20 was as big as I could go. Does anybody know what the truth is here? I don't want rubbing.

I guess I'm one of the few people that has 17" rims I'm wanting to run either a 285/70 or a 295/70 with a 17x9 rim what is the most offset I can do with a 2" level.The wheels im looking at come in +25 +18 and 0 offset.I can deal with a slight rub but don't want to trim.

I've got a 2.25 inch Pro Comp level and I'm running 305/55/20's. No rub with a +12 offset. Edited by Trza

How do you account for offset? Or how do you "offset" the rim? I'm running the factory chrome 20"s. I think they're a 20x9. Is there an offset on these rims? Is that what you're referring to? I thought you had to buy the rims with the offset already there, i.e. do the factory rims already have offsets? I don't think they do. Correct me if I'm wrong here. I'd love to run a 305/55/20, but from what I've been reading, I can't do that without an offset rim. Are you suggesting I buy rims that are offset so that I can run the tire I want? If so, I probably can't do that. Already spent an arm and a leg upgrading to 20" factory wheels from the stock 17's. I need to keep the rims that I've got. Can I still run a 305/55/20 with the rims I have?

Wheel offset is just the distance from the hub mounting surface to the wheel centerline. Factory wheels are generally in the positive. +20 to +30 . The smaller offset number you go and into the negative which gives more lip, the less tire you can run without rubbing. On factory wheels like yours you should be able to do the 305s with maybe minor rubbing on the wheel liner. Many people are running that size. Depends on which tire as well as each manufacturer tires are a bit different in size.

I have a 2015 Sierra All Terrain, running a 2.5" Rough Country level and Toyo AT2 Xtreme 295/55r20 (33x12) tires on the factory 20" wheels. I know the factory AT and Denali wheels are both +27mm offset, it's stamped right in the back. I'm assuming the Chevy 20's are also the same. Saying the MAX tire size you can run is kind of irrelevant because a 305 Mud Terrain is going to be wider than a 305 Highway Terrain, and no brand is exactly the same size.

What I can tell you for sure, is on stock +27mm offset wheels you WILL rub the control arms with a 305/55r20 (33x12.5) wide tire. Everyone is always concerned about rubbing fender liners but that's plastic that can be easily manipulated. The control arms and sway bar are however a little less forgiving if you're rubbing up against them.

 

Here's some pictures of my truck:

20150207_212234_zpsd8dqtydw.jpg

 

You can see where the sidewall rubs the UCA and sway bar at full lock. I know of two other forum members with the exact same tire on factory 20's with the same issue so I know I'm not alone.

 

Seeing that the 295's rub, I guarantee the 305's will... It's the wheel offset thats killing it, many forum members are able to run the 305's with no clearance issues by simply running an aftermarket wheel with +12 or +18mm offset.

 

For sure you'll clear 275/60r20's (33x11), I've even heard of guys running 275/65r20's (34x11) but they might slightly rub the inner fender liner that can be zip-tied back. I'd be willing to bet that a 285/60r20 (33x11.5) wide tire would be the ideal size to clear the fenders and control arms, but pretty sure that size is only available in the Goodyear Duratrac's.

 

Another thing to consider if you care about fuel mileage is tire weight. Initially I thought I could fit 295's or 305's and only decided on the 295's because their 14lbs lighter per tire when comparing the 33x12 to the 33x12.5.

 

I'm going to try and add some 8mm front wheel spacers to simulate a +19 offset wheel and see if it's enough to push my tires out far enough to clear the UCA's.

 

Crawl under your truck and see what you're wheel offset is, it should actually say "20x9 +27mm Offset" or it might be one big number like "20x9JXIS27", either way knowing your offset is crucial to figuring out "what fits or not".

Awesome reply hutch08! I REALLY APPRECIATE IT! And yeah, my wheel says 20x9j and then Offset 27. Let the shopping begin!

No worries, a lot of people just say "don't worry about it, and just deal with it" but I'm too big of a perfectionist if something isn't "right" HaHa.

Maybe if you have a good tire shop they'll test fit a front tire and see what kind of clearance you have at full lock... Good luck and let us know how you make out!

You're so right! I DO WORRY! But yeah, I'm pretty sure I'm gonna go with a 275/60/20. That'll give me some size and cushion, AND won't cost me an extra $100 per tire! LOL! Not going to get any new tires yet. The cruddy ones I've got now are brand new. No sense in swapping them out until I've fully run through them; but I'll keep you posted on when the newbies go on. For my money, ratings wise the Bridgestone Dueler H/L Alenza Plus' look the best. "H" speed rating with a 80k mile warranty. All for just $185 per tire. That's a good deal for a HIGHLY rated tire.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
