which size tire should i use for a 8.5 wide chrome iroc wheels? i want to put some 275 wide tire. do you think it will fit?

 

i was lookin for a 275 for my 16x8 irocs but they dont exist. well they do but not the ones i wanted. provided your irocs are 16 inch the best tire ive found is a 255/50 rear and a 245/50 front. plus correct me if im wrong but arent irocs 8 inchers not 8.5. anyway the only 275 i found was a 275/60/16 to much of a side wall for my tastes. if your rims are bigger than 16 tho you should be able to find a 275. and it will fit and look great. good luck

their some irocs that are 8.5 depends where you buy them

 

this is a little off subject, but i'm curious, on my stock irocs, REAR and FRONT is stamped into the metal on one of the spokes...but the wheels have exactly the same tires on them...can i do a 4 wheel rotation, or do the FRONT rims have to stay on the front, and the REARs have to stay on the back??

 

My 92 Z28 rims say that too. I think all third gen wheels do... I just leave 'em where they belong. They may be weighted differently or somthin, don't wanna mess em up.

 

I Think the back and fronts have different offsets.

 

you can't rotate them, they are different. Rear is for rear only and vice versa.

 

but why?

 

all iroc rims and all 91/92 z28 rims are offset differently front to back. these wheels can not be rotated due to this. front on fron, rears on rear.

 

The backset is different on those wheels. Fronts on back will stick out pretty far, backs on front might work but not quite right. I think this design just sort of grew over the third gen years and they didn't want to redesign the car to fix it as they did on the fourth gen cars. Note our cars use the same lower A-frame and brakes as an S10 pickup for instance.
