1957 Widest & Tallest Tires

I am replacing my biased tires on my 1957 Thunderbird, with radials. I would like to have the widest/tallest tire possible. I have researched. And I am not sure if the 215-75R14 Coker radial tires would be touching the ball joints in the front? Anyone have these tires on their 57 Thunderbird? I know the 205-75R14’s will work.. but wanted a little taller/wider if possible. Thanks

215/75R14 tires are 26.7" in diameter. I have 215/70R15 tires on my 55, which are 26.9" in diameter. I have no clearance issues in front. However, if you have skirts, particularly if you ever intend to put spoke wheels/w skirts, I would not go larger than 205/75R14. Without skirts, 215/75R14 should be okay, as long as your rear clearance is equal to or greater than the 55's. This, of course, is based on your springs not being warn out and your ride height being correct. The rear clearance is tighter than the front. If you go with aftermarket wheels, make sure they have the correct backspace/offset. 215/75R14 and 215/70R15 are the same width at 8.46."

Tire sizes are very misunderstood. The first number is the width and the second number is the is the height/width ratio. 205/ 75 X 14 is the closest to the original bias ply tires. Any wider and you will not be able to use the fender skirts. Finding a tire that is thinner say an 80 aspect ratio and taller would be almost impossible unless you want to spend over $ 200/tire or more for a custom size. Now you are almost talking truck tires. Any taller would throw off your speedometer also. Fewer revolution/mile.

I have replaced the tires on my 56 Bord and have gone with 17" rim x 8" wide configuration without anyproblems. Cloys 17 " wheel with Firestone 215/55R17 tires, looks and drives great.

I'm running 215/70R14s on my 57 with skirts. I added 10mm spacers on the front and had to do some massaging on the skirts.
I also added the rear stabilizer. no issues at all
