How do you plan on adjusting the odometer for that taller tire? Word is by GM that even if all you do is change the odometer stuff if you have any powertrain issues GM can use the fact you tuned the ECM to fix odometer error due to non stock size tires to deny powertrain warranty issues.

I'm running P275/60r20 Open Country AT2s with a 1" level. I have about 1500 miles on them and they are awesome. The tires rub the front driver side wheel well liner in reverse at full lock. Even with a 2.5" level kit you may still rub but it won't be bad. My speedo is off 2 mph at 70 mph. If those 275/65r20s are LT tires you are going to notice a significant decrease in acceleration and MPG but they will look great.

I have 275/60R20 Cooper AT3 with 2.5" RC lift kit, no rub at all and looks nice. 275/60R20 was the biggest size P tires that I could find, as I didn't want to go with LT tires and sacrifice MPG and the soft ride.

Any rubbing? A local shop is going to install a 2.25 Ready Lift kit for me, but they are afraid I can't fit those tires on aftermarket wheels - they said they have only put this big of tires on factory wheels.

I think they will work fine, mine don't close to rubbing

20x10 fuel hostage - 24 offset

305/55/20 Falken wild peak a/t

 

It did rub a little, I just cut a small piece of the back mat and hammered the sheet metal about 1/8".

as long as you use a 20x9 with 0 offset you should be fine, Once you use a 20x10 wheel thats when you run into problems but if you want the deep dish look the 20x10 wheel is the way to go. Just stick to a 5" backspacing and go with 285/55/20 to be on the safe side. It will still look aggressive if you go with mud tires or all terrains.

I've got a 2014 Denali.

 

I've got the 20x9 KMC D2's and Toyo 285/55r20 sittin gat the shop ready to go.

 

I ran the same combo on a 2012 Avalanche with very little "reverse-over-a-bump-rubbing-at-full-lock" rub

 

Do you guys think I'll need a level? Hope not.

Most likely, with 285/55/20 on a 20x9 -0- offset wheel all you will probably need is a 2" leveling kit. No need for 2.5" or taller leveling kit with 285. With a 2.5" leveling kit and 20x9 wheel -0- offset people have been putting 305's with no rub.

Im wanting to run 275 70 R18 on stock wheels with 2 inch rough country lower strut mount leveling kit. Will they fit?

 

You should be fine

YQatari do you have any pics? Would love to see them. As for mod the speedometer I hadn't put much thought into that yet. Would hate to void the power train warranty... As for LT vs P? I have no idea what that is

LT tires are 10 ply, P tires are generally 4 ply. LT or "E" range tires are heavier and tougher, usually have stiffer sidewalls and resist flats better the P tires. *Most* people don't need LT tires.

Well guys here she is leveled and new skins. I haven't discovered anything rubbing and the ride is incredible over those crappy Goodyears that come from the factory. Leveling Kit was a $40 Ebay 2" level kit, Aluminum spacer. Also New Nitto Terra Grapplers, yes they are wide 305/60/18. The look is awesome compared to factory. Here are the images.

    • True. My statement needs qualification. "For a shade tree mechanic, re-assembling the front engine to achieve a rough baseline timing of 0 degrees, as is approximated and indicated by common visual indicator mark alignment, measured with a human eye capable of 20/20 vision *with correction, I am reasonably confident that I have followed the outlined procedures/ prescribed methods for verifying baseline timing."   😉   In the end, the computer sets the timing, it's continuously variable based on sensor input, and the distributor only has a degree or two of physical adjustability intended for dialing in the final setting for cam ****** once everything is back together. But even that final value is acceptable within, I believe, +/- 3 degrees.   I thought my exhaust project was going to be a bear. To my surprise, the old clamps came right off last night, and I was able to unbolt all the hangers instead of having to muscle the rubber mounts. The old cat is ready to slip off the factory y-pipe. The rest is ready to come out with one or two cuts, and I've got a fresh blade waiting. I love living where rust isn't a thing.    
    • I work at a Chevrolet dealership & hear it all believe me.  Just reads like there's going to be a fist fight over filters.  Can't get enough, continue!!
    • I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ). 
    • Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol    
    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
