Another user on this forum said this isn't accurate he installed 295/60 r20 which is 33.9X11 and had to do ALOT of cutting. I'm getting close to purchase new wheels so I am trying to get the correct answer as well. I'm surprised this isn't know yet.

Does anyone know what the biggest tire is that will fit the stock 20" wheel on a 2021 Yukon AT4? I actually ordered the 295/60/20 BFGs and then saw this forum so had to cancel the order! Thanks in advance for any help

I am picking up a Yukon xl at4 in a week and wondering if 285/65/20 tires will fit on factory stock suspension?

May I ask what you ended up with?

Based on everything I’ve looked at and read through, the largest tire that will fit (without rubbing or trimming) on a stock 20” wheel for a 2021 Yukon AT4 sitting at stock height (which would also account for a Yukon equipped with air ride suspension) is either 285/60R20 or 33x12.50R20. The 285 will be a little taller (approx. 33.5 inches) and a bit narrower (approx. 11.2 inches) than the 33x12.50 tire. The space between the control arm and the tire is tight with the 33x12.50, but I put them on my wife’s 2021 Yukon AT4 (with air ride suspension) and have not had a single problem with rubbing at any of the selectable ride heights.

Note: I did replace the 20” AT4 wheels with 22” Denali wheels, but the width (9”) and the offset (+28mm) of the wheels are the same, but because the 33x12.50 measurement isn’t affected by wheel size (as aspect ratio of the wheel is not a factor in SAE-sized tires): you shouldn’t have any problems.

Recently put some NITTO - Recon Grapplers (285/60/R20's) on my stock 2021 Yukon AT4.

Looks good! How's the ride?

It did feel a little more rough when comparing to the stock tires that were on there before. However, after a week we've definitely gotten used to it and loving the more aggressive look. I ended up going with the Recon grapplers as the Nitto site stated the Dura Grapplers might be a little more noisy.
