Max Tires Size w/ New T6 Leveling Kit Awesome!!

rockytckr · April 13, 2012

Here’s some updated information for people looking for the max tire size to run on a newer Chevy Silverado 1500 with a leveling kit. I own a 2011 Silverado LTZ and I wanted to level it and wanted to run the biggest size tire without cutting up the truck. I tried to look it up, but the max size that I could find was 275/60R20. The size was ok, but the tires width was just too skinny (The wider the better looking). I could have purchased after market wheels more of an offset, but when you do this you don’t get the max life of the tires that you run. So I wanted to keep my factor 20’s and just put bigger tires on. So I found a tire shop willing to try on a tire size of 305/55R20. I was amazed that the only thing I had to cut was the inner corner of the front mud flaps. The tires are 33.2 tall and about 12.4 wide and they look great with no rubbing at all. Now I don’t know if the 2011 models have a little bit bigger opening space for the front wheel wells, but that tire size fits perfect with no rubbing. *Note (I am running the NEW T6 Billet leveling kit by ReadyLift, I believe it gave me a little bit more lift than the standard leveling kit). I hope this helps every one that is looking for answers on what tire size to run with a leveling kit.

Nice! Looks great!

A buddy of mine is running 305/55/20 Cooper Zeon LTZ's on stock 20's with a 2.5" kit as well.....and he just had to trim a little bit of plastic. The trick seems to be running those factory wheels!

what stock 20s does he have?

I have the tahoe 20s and I love those tires...had them on my tahoe but not in a 305/55/20 and if I could fit that with minimal trimming that would be awesome.

*Currently have fatbobs 2" level but want to switch it out for a 2.5 and swap the rear block for one out of a GMT800

Any newer style chevy 20s are going to be 8.5" width.

offset may or may not be different though.

I see them all day long and the chrome clad 20s and my 20s definitely don't seem like the same offset but they may actually be the same.... i don't know....thats why I was just looking for verification

Any gmc/chevy oem wheel for the gmt900 should be same offset. Looks good but you need a rear block. Unless you don't put any weight in the back. Good info and should get alot of hits from people posting what size tire fits.

My wheels are from a tahoe. I assume that there is no difference though...
