3rd Gen 17's
 

Looking at wheels for my 86. Will 275 50 17 fit? Anyone run these? Are spacers needed and will I have a problem rubbing the LCA/frame when turning the steeing wheel from lock to lock?

I have 275/40/17s on the vert buuut Im running a 4th gen rear and 2" spacers up front for the 2001 SS wheels.

I just have some slight rubbing up on the front wheels cause the ASC installed SFC's Other than that, no problems what-so-ever.

I'd say the 50's will be too tall; go for 275/40s. Ted is running 17x9's with 275/40s at all 4 corners on his '89 IROC, and it looks damn good.

I have 17x9.5" ronals with 275/40-17's they fit perfect and never rub on my formula.

ROH 17x9s with 275-40R/17s all around, no spacers needed, minor rubbing on the plastic fender liners at steering lock.

Seeing as this was a "factory" wheel for 2 years there should be no problem. I also have the R15's and the same tire size, I occasionally rub on the plastic fender liners. I think you can adjust them a little though.50's would be very tall and throw the speedo off quite a bit.

Actually it's only ~1" taller, and the speedo would read 4% slow.


275/45/17 is definitely the way to go though.

275/40/17 would be ~ stock height, so the 50 would be ~ 1.2" taller aprrox 8% slower. at 70 on the dash he would actually be going 75? Is my math correct there?

Yes.....me FTL on that one.

Actually it's almost 2" taller than stock and the speedo would read 8.4% slow.

Correct....
