Which are right tires for 1971

Existing tires need replacement. They are 235/60/15. Book calls for 235/70/15.
Also can I think they said 255/70/15 fit with no problems.
I would like to go a little wide and the 255's are????
Any help.

Re: Which are right tires for 1971 (John D.)

The correct Tire Size for 71 is F70-15. According to this chart I found that is
equivalent to P205/70R15

I like 255/60/15's on the rear, but hated them on the front, had problems with wondering and rubbing on sharp turns. I now have 225/60/15's on the front, MUCH BETTER.

I run 245/60/15 BFG Radial TAs on my 72 with no problems whatsoever. Good tire and nice ride.

Re: Which are right tires for 1971 (John D.)

I was told the closest size to the F70's were 225-70's. I replaced GR60's on the 69 with the 225-70's and it was a night and day difference-so much so I never installed the PS setup I bought for the car. I'm going to run the same tire on the 72.

Actually the correct current day service replacement size is P215/70R15.

Re: Which are right tires for 1971 (gq82)

FYI....I have P255/60R15 Goodyears GTII on my '72 with no problems....

Note: Sig shows P245/60R15's that were on the car when I bought it. I've since changed to the 255's.

Re: Which are right tires for 1971 (John D.)

I got my BFG Radial TAs from NTB a few years ago, and they said the book called for P225/70/15 so that's what I got. Now I'm sorry I didn't research it a little better because the 70s seem to "tall". When I replace them I'm going for 60s and probably wider too.

Correct and I run that size on my 70. For originality, find ones with raised white letters.

I agree that the wider tires wander more.

I would like to see pictures of actual corvettes with P255/60R15 tires and also corvettes with P215/70R15 tires for comparison purposes.

Just look at the 1979 Corvette sales brochure for the L82 Vette - it came stock with P255/60R15 tires.

From the side, the two tires you mentioned will look the same - they are the same diameter within 0.10". The only difference is in the width: The 255's are 10" wide, and the 215's are 8.5" wide.

Correct tires for a 1971 C3 were F70-15's. The equivalent of that in a radial tire is 215R70-15. But, folks like wider tires than that...and when you go 'wider', the tire diameter gets larger...and the speedo calibration goes whacko. 235R60-15's are nearly the same diameter as the F70-15; and 235 width tires are the widest that will ALWAYS have clearance to the frame and body parts in the front end of '68-77 cars. Many will accept 245's without rubbing; some will take 255's. Front end wheel wells were opened up in 1978, so '78-82 will take larger tires up front [and rear].
