I have a 2012 fx4 with the 20" rims. Need to get new tires soon and was wondering what the biggest size i can fit on the stock rims with no lift or leveling kit on it? I was looking at 275/60/20 or 285/60/20 but not sure if the 285's will fit on the stock rims and not rub.. Anyone let me know please?

 

Yes, both sizes work/fit fine.

 

Both sizes will fit fine on stock rims with no lift/level, but honestly, I would go with the 275s. The 285s are only 1/4" wider and 1/2" taller, and they cost $50-100 more per tire depending on what tire you go with, which isn't worth it IMO.

 

Excellent thanks guys for the input!
