Tire Size


Recommended Posts

I'm struggling on trying to figure out what the biggest size tire I can put on my 2016 Sierra 2500HD with a leveling kit. I'm going with 20×9 wheels with a 0mm offset and thinking of either 295/60 R20 or 305/55 R20. I'm looking to get the wheel as flush with the outside lip of the fefender flares as I can and at the same time try to have as less space between top of wheel and fender ad possible. Does anyone have any ideas?

had 20x9 wheels (+18) and 295/60r20 NItto ridge grapplers and they would not fit even if I leveled my 2018 silverado 2500. The 305/55 might work with some trimming of mud flaps, air dam, fender liner but can't say from experience.  Hope that helps
