i know i shouldnt post here but you guys know a lot. My dad is putting rims on his '02 denali, and they are foose 111 heat. they are 20x8.5 . tire rack says we should use 285/50-20 tire. however the goodyear tires are the only ones in that size and he doesnt want those. my question is what other size of tire can he use? 295/45-20? like what is the maximum width i can use with 8.5" wide rims? he really doesnt want low profile tires either. wants pirelli, sumitomo, yokahoma, falken, nitto

thanks

 

What was the stock tire size on his Denali? He has to pick a tire that will match the original outside diameter in order to avoid altering the speedo, suspension geometry, etc.

 

stock tire size is 265/70-17. so your saying with the bigger wheel he would have to have a lower profile tire to stay at stock diameter? thanks for your help

 

would these tires fit on 20"x 8.5
Size: 275/55R-20 116V they are the nitto suv tires

what is the widest or narrowest width i can put on them?
thanks
