i ahve a 1980 z with a 8.5 ten bolt posi. i was wondering if anyone knew what the bigest tire i could fit in the back, in a 15 of 16 inch rim

 

On a 15" rim i fit a 275/60/r15 and it came right to the edge of the wheel well.

back in the day

 

what do u presently have now, and was the total for the package, because your ride looks bada$$

 

right now im running.

255/45/16 on the back and 235/35/16 on the front

im moving to 17s on the back next season, but i can still go a size larger on the back.

for price, i payed 2200cdn for the rims

 

When I had my 15" rims a few years back, I had 255/60/R15 on all four corners.

The sidewall flex with this set-up was simply awful.

I personally do not recommend it.

 

I have 275-50-15's on the back of mine on 15x8 wheels. They fit really well.

 

I have 295-50 15's on 10" rims on the back of my 71. With rolled fender lips, it scrapes a little on big bumps. If I had used 5.5" back space instead of 5", I think it would have been centered just right in the wheelwell and it wouldn't scrape.

 

Ditto for my dad's '73.

They fit fine...........they just don't hook.

EDIT: sorry, I just realized we have 60 series tires, not 50, so they're 275/60/15.

 

probably because 255s are simply to big PERIOD on the front with out alittle modding, and it wasn't setup right on the back if u were having problems.

do u think something like this would fit, 17 x 8
i want to have bigger tires in back hen in front, i saw some 17 x 10, but i doubt that would fit, what is the price range for rolling a quarter, compared to mini tubing

 

I actually did not have any problems with rubbing, interferance, etc.

My "not recommended" comment pertained to the massive sidewall flex. - Handling just plain sucked.

Besides, I assume that the original poster has the stock Z28 tims which are 15X7 - this rim is too narrow.

Now, if ryan80z were to buy wider rims with the proper BS - then 315's are possible even.

Just my 2 cents.

 

I'm running 295/50R15's too, on the rear and 235/60R15 on front.
just rolled the fenders a bit. Just rember to hammer out the seatbelt bulge in the rear.
