Haha, I’ve asked this question also. It does seem like the collective knowledge base here could provide a quicker answer. Probably would take less time to type 275/60/20(not the answer). [emoji23][emoji23]

 

I’ve researched, and haven’t necessarily found a 100% solid (to me) answer. Depends on rims too, and the height of mine after leveling isn’t as high as some I’ve seen, measured from ground to fender. So, I’ll probably be conservative and go rims and stock sized, more aggressive tires. I don’t want to trim anything.

I still cannot figure out two things. One is the search on this site is not very precise. How do you use google search instead?

Also, I have the same tire fitment questions everyone has. What to know what is the largest tire I can fit on 18 in rims with my 2020 AT4? Can I do 285 or 295 /70's or 75's. I know the speedo will be off a bit, but I am looking for a slightly different ride. Like the one on my old 2006 HUMMER H2. 

 

I know makes no sense, but its what I like....

For example, in the Google search box type 2020 silverado max tire size gm forum  You will get plenty of hits including this thread.

I put 275/65/20 Goodyear Ultraterrain on my 19 Silverado LTZ with a ready lift level kit and have no rubbing at all. Basically a 34"x11.5"x20"

Looking good, a more aggressive tire on a nice aluminum rim that isn't a 20 looks excellent (more tire less rim is best). It looks nose high, I take it you didn't add a rear block to keep some rake? Also did you adjust your headlights down? That is going to piss off on coming traffic quite a bit...

Your truck turned out great, I really like that look. Very clean. I would also encourage you to adjust your headlights slightly. Simple phillips head screwdriver and 30 seconds of your time.

 

I know there's a lot of these threads but I never get the answer I'm looking for. That's probably because nobody's done it-LOL. I want to add LT275/65R20 tires which sounds like the overwhelming popular size to go with when leveled. But I don't want the 2" level, I am only looking to increase 1.5".  For those of you that can look, say wheel fully turned and in reverse... how much room do you have until your kissing the liner/mud flap? Eye-balling it if your front was lowered by 0.5" (ie 1.5" level instead of 2.0") do you think it would rub? Tire size fit with minor trimming? Or have to do major trimming/or not fit at all.

 

Thanks. I'm towing more so want 1.5" up front and a 2.0" block in the rear to start with. This hopefully would get me just clear enough for better larger LT/E-rated tires and leveled when hooked to the trailer.

    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?
    • That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?
    • That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?  
    • Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
