I know this question has been asked 1000 times and i did search and i found PLENTY of info on what i wanna know but people get off topic so fast and its gets kidna confusing. I have a 92 z28. The wheels are 15x8. Will 275/60r15 fit nicely and not rub in the rear?


By the way. I am not a newbie that jsut got into cars, I am a ford technican in Queens NY. I do build cars. curently finishing my 450 whp nissan 240sx. and my 427 small block that will be fitted into my half tubed 1986 rx7.

 

Your stock wheels are 15x7.

 

where in queens, i work at a body shop and i have a 87 iroc, i have some 16 inch iroc rims if you want them....

 

You can't put a 275mm wide tire on a 7" rim, its just not safe. The max you can go is 265mm, but even that is not advised. If you want 275mm wide tires go with atleast a 8" wide rim.

 

Why do you have 15x7's on your 92 z?

 

I dunno, I thought they were 15x8. Thats kidna shady. Im try and measure them tomorrow.

 

Stock wheels for the Z were 16x8, 15's only came on the base model camaros.

 

Correct. 91 and 92 V6 cars got the 15x7's that you have now. Every 90 and previous RS got them as well.

 

well ig uess the guy before me changed them. The car is definitly a z28 but i think the wheels look good.

 

yes, they were definately changed, and also the front end has been lowered and perhaps the rear raised as well.

see my sig for link to pics of stock wheels and ride height for 90-92 z28.

 

or he just has sagging springs

 

to answer the question, a 275 will not rub. but your looking at a T rating and you shouldn't mount wide tires on a 15x7 wheel. if you want to stay with 15's, you should get atleast an 8.5 inch wheel and mount on some 295's. i've heard some companies are disc. the 295 sizes though.

the wider the wheel, the more you'll equalize the sidewall with the tred which is a good thing. too small a wheel will cause the "bulge" effect in the sidewall and can cause the tire to dismount around cornors.

 

I think you mean the other way around

 

no, i don't. i see so many tires a day it makes me sick. if you got a nasty bulge that does a concave in to the wheel, thats bad. its like mounting a 295 on a 15x7 then mounting it on a 15x10. you should never mount a 295 on a 15x7... why? the bulge effect. on a 15x10 it seperates the walls apart and they have less shift around cornors.

 

by bad, I was thinking tire when you said wheel.

 

heh not a problem man, not a problem at all
