Tire and wheel size for 65 GT Convertible

1st Official Post

    I have a 1965 GT convert with the stock 14 x 5 styled steel wheels with 195/75 x 14 WW Firestones on it. They look a little undersized to me and I would like to upgrade to 14 x 6 styled steel wheels with 205/70 x 14 WW's from Coker. Has anyone seen this setup on a 65-66 vert? Do you think I will have any clearance issues? My car has 100% stock 65 GT suspension on it.

    I run 205/70 14s on the original 14x5 styled steel wheels on my fastback and they look great with no fitment issues. This is a common setup and I have used on several cars.

    Have also used 14x6 wheels with the 205s.

    I put the 6.95 Bias Ply tires on when showing.

    Is your issue in diameter or width? I am pretty sure that the one step up in size will be compensated by the lower profile of the 70 series as far as tire diameter.

    You can go to Tirerack, pick a tire and compare all the specs for any given sizes, such as height, width, and suggested rim widths.

    Since last year, on my fastback,

    I’m running 205/65R15 Firehawks on Magnum 500’s, perfect in the wheel wells, I think. Just a tad taller and narrower than the 215/60R15 BFG’s I was running for years.

    If you are considering new wheels, think about 15’s. They make a Styled steel in 15..

    I guess my main concern is if the 14 x 6 wheels which are made now and have 4" backspacing will work with no interference issues with my stock front disc brakes. I have looked at the different tire charts and have compared tire possibilities.
