'84 Trans AM Tire Size

Anyone running 245R60 tires on these cars? I believe that they should fit & thus replace 215R65 tires. Comments?

Re: '84 Trans AM Tire Size

I just ordered BF Goodrich 245/60/15 Radial T/A tires yesterday for my 1984 TA. Jegs had the best price shipped to my door - $778.61. I’m hoping to get the new tires mounted on my stock rims this weekend. I’ll let you know my thoughts and post pics after they’re installed.

An Optional P235/60VR-15 Was Available In 1986 From The Factory So 245's Should Fit

235/60r15 is the same overall diameter as the stock 215/65r15. 245’s will be taller, will cause the speedometer to be off and may rub in the front when turned full lock.

I just installed four 245R60X15 BFG Radial T/A on my '84 Trans AM today & they look great. 245R60X15 is 2.3% greater circumference than 215R65X15. Thus no need to change speedo gear.

Re: '84 Trans AM Tire Size

Finally got the new 245 tires mounted & installed on the car today. Car rides wayyyy better now. Old tires were 11 years old and dry rotted. I think they look good. I’ll try to take some pics soon.

On my car, which is dark royal blue metallic, the wideness of the tire & those white letters look great.
