Dumb tire question












FWIW, I suspect the all season is not coming up, probably due to speed rating Corvette required....
The Best of Corvette for Corvette Enthusiasts
Not always...... could be 315 and 275 combo. Also, I dont know for sure, but did the 96 not have the option of 9.5 wheels on all four corners with 275 tires on all wheels as a option?
Then of course, I think the base was 255 on front and 285 rears.
Z51 not available on convertible use four 275 40 17 aka square set up.
Grand Sport Coupes got 315 rear and 275 fronts. Convertible had standard tires.
I stand corrected.... I thought all GS got the 275-315 combo, but I was wrong on verts.






Thanks for all the suggestions.

But there's a solution! If you really want all-seasons, then substitute 245/45/17 front and 275/40/17 rear.* These are a better fit on those 17x8.5/17x9.5 wheels anyway, and this gives you literally dozens of choices in summer or all-season tires. At Tire Rack, for example, there are six choices in the category of "ultra high performance all-season". Among those, I have experience with the Rikens, which are decent for a very cheap price (i.e. good value). Someone earlier mentioned the Coopers being very good, and I've heard/seen good things about the BFGs.
All that said, if you don't drive your car in freezing temps, then I'd get the Continental EC Sports in either size. They are outstanding very-high-performance tires (confirmed by lots of autocross and road course work) and probably one of the two fastest rain tires you can buy for street use.
*Don't use 275/45/17 on the 8.5" front wheels. That's a misfit and will result in worse performance, and it will look goofy.

- No, the 285s will likely perform worse because they're a bit pinched on a 9.5" wheel. They're also taller, which raises the vehicle CG and also its roll center, both of which mean more lateral load transfer during cornering, and the higher CG also means more forward load transfer during braking. All bad for performance. The only reason Chevy went with these bigger tires from 93-96 was to add cushy ride quality and reduce tramlining. The performance suspension options (Z07 or Z51) always went back to square 9.5" wheels with 275/40/17 tires.
- No, in my opinion they look worse than 275s. They look a little "balloonish."
