largest r20 winter tire size that can fit without rubbing for 22 G63
hey all looking to get winter tire set for a 22 g63. don't want to get any of those aggressive looking all terrain tires. for a r20, 275, 50 r20 seems like the stock size but idk I feel like the tire looks too small for the wheel well.
my truck came stock with the 295 40 r22 and tbh even I think those look small as well.
I did some playing around and seems like 275 55 r20 is a tad bigger then the 295 40 r22 and should fit without rubbing. Just wondering if any other larger sizes can still fit without rubbing
I did research on the forums and alot of people run diff sizes with those all terrain tires but not sure if the 'aggressive' look on those affect the sizing compared to a winter tire
I also saw that 285 55 r20 may also work but it seems to be hard to find a winter tire in that size unless im mistaken
thanks!

G550
My G550 came with 275/50R20's and I changed them to an A/T 3MPSF rated 275/55R20 -- no rubbing problems despite about +1" diameter increase. 295/40R22 is 0.6" smaller diameter than 275/55R20, but 0.8" wider. Wider might have a bit more traction, but also more resistance if you're driving through deep snow. In winter driving, performance always wins over looks. And 20" wins in selection, price and availability.

I went through this and a lot of research. The largest size you can fit with zero rub and zero suspension rub at full suspension articulation is 275/55R20. There are larger tires that do work on a day to day basis without full suspension articulation, so it's up to you.
Falken Wildpeak A/T3W 275/55/20 is what I went with. I have them on all my other cars for winter tires.
