I already have the tires and was wondering if they might warant the purchase of some 17" wheels....
Would 225 60 17's be to narrow? for 8" wheels?

Too narrow for an 8" rim .

Tirerack shows most of those size tires fitting a 6-8" rim width with 6.5" being optimal. Also a little taller than stock at 27.6". Also, none of the tire in that size at Tirerack are what I would call performance tires.

I don't think the measurement at Tire Rack is "optimal" -
I think it's just what they measure the section width with.

I have 8.5 inch wide aftermarket wheels on the front
of my Supra and the stock 235 width is recommended.

The 8 inch wheels on C3s came with ~225 tires originally -
I don't think the lower aspect ratio of the 60s would
create problems.

OK The tires are from a dodge intrepid R/t.. the actual tire size is

225/55-17 I was recalling it wrong.... Is that much better?

Steve439

That's actually better - pretty close to stock height.

The only thing siily is that they have raised YELLOW letters...
Goodyear's ..... but I already own them.......Hmm.
Tempting. to get some of those 17" rally wheels.. I wonder how crasy My car would look..

White 77/ raised YELLOW letter tires and 17" rally wheels... Might not mix well....

Turn the letters in 17" wheels look better w/black wall tires. but if your going to do that sell them & buy a wider tire that will look & perform better on the vette. yellow letter tires are worth $$ now I think G-Y stop making them..

OK, but in my opinion, still too small for an 8" rim. You can get a 225/70R15 on a stock 8" rim because the 70 series sidewall has more flex. The 55 series has a lot less flex. Do you really want to chance it?

You can get Kumho Ecsta SPT in a 255/50R17 from the Tirerack for $114 each. Ranked 6 out of 44 ultra high performance summer tires at Tirerack. Why skimp?

Tire Rack shows that 225/55 17 will fit 8" rim & height slightly shorter.
255/50 17 would be very good for 17s.

77 size was 225/70 15. 235/60 15 - 255/60 15 fit the rim better. The 255/60 15s that became available later were an appearance option.
