From the threads that I've read, it looks like the modern stock tire size for my 71 is 225/70R15. This results in 27.4" diameter. Others have said the stock wheel has 27" diameter which equates to 255/60R15. Is the stock wheel 27" or 27.4"? I'm trying to get a set of tires for my 17" rims and I want to keep the speedometer as accurate as possible. Thanks.
But I read some posts stating the stock size is 225/70R15 which has an outside diameter of 27.4". If I go with 255/50R17, it will only give me 27". Will that make a big difference in the accuracy of the speedometer? Thanks.
According to Tire Rack says your 71 size should be 205/70 which are 27.1. Later years call for 225/70 or optional 255/60. What size are you running now. Compare that size to the others.

I have 255/60R15 right now.
Tire Rack says 205/75R15 and Discount Tire Direct says 225/70R15. I have no idea which has the correct size.

The original tire size for the 1971 Corvette, for that matter '68 thru '72 cars is 215 70x15. I am still running thee original tires on one of my '71's.

Thank. 215/70-15 is about 26.85" that is pretty close to 255/50-17.

Did you mean 205/70?
Well, when I enter the info for my 71, Tire Rack said 205/75-15.
Research complete! Bridgestone Potenza RE750 255/50ZR17. Thanks for all the help.
Looks like a good choice. Please post pics when you get them on. I am runnning 255/50X15 on the 65 now but I plan to go to 17s. That is the size I was considering as well. I would like to see what they look like on the rim. I want newer design tires but I don't want the tire sidewall too thin. I think this size will be perfect for me as well.

Will do. The rims should arrive next week. I have to shop around for a good price on the Bridgestone tires.
