Biggest size tire for stock 20’s

Hey guys just wondering what would be the biggest size tire I could fit in stock 20” rims w/o leveling kit that would not rub anything at all on truck ? Let me know and pics would be a plus if possible. Looking at getting either a hybrid type tire or MT , let me know what u think

37x12.50r20 fit very nicely with no lift or level. They do rub on the radius arms, but its only at full lock and its not that bad. Wears the paint on the arms, thats about it. 35s should fit with no rubbing.

295/65/20 Toyo MT or Toyo AT or Nitto Trail Grappler. The Nitto Ridge Grappler in this size runs wide and will likely rub the radius arms at full lock.

35's are the biggest you can run without rub. 37's will rub.

37’s are unbeatable if you can bear the sway bar and radius arm rub. No body rub. I’m doing sway bar and radius arm replacements in the spring to eliminate rub without lift.



‘As others have said f you want no rub you’re looking at 35x11.5 or smaller Liquidsteam on here did the 37x11.5s And still had rubbing.

What sway bar and radius arms will you be going with to avoid the rub? Have you quoted the job out yet and have numbers to share, if you don't mind?

What about BF Goodrich KO2’s? Will it fit on 35/12.50/20 without rubbing?

35x12.50R20 won't rub anywhere, you don't need an 11.5 inch tire. Pretty much any 37 will rub no matter what you do with those stock wheels.
