VCCA Home Forums TECHNICAL - 1945 AND NEWER 1946-1948 Tire question

Finally got the last of the chassis and brakes finished up and before I put the engine/tranny on the chassis I want to replace the tires. Currently it has some 6.75 x 15 tube tires on it but I would like to change out to a similar size tubeless radial. Rather than figure it all out on my own I figured I would start by running the question up the vcca flagpole.

Is there a tire size that works well as a direct replacement for the originals?

P205-75 15 is the replacement size. They are slightly wider and lower than a 6.70 X 15. The 215 is closer to the corect diameter but kind of overly wide looking.
I would suggest not buying the tires until you are ready to do some serious drivng. Radial tires can loose their tread when they get a feew years old.

Thanks, that's pretty much what I had guessed using a tape measure.

Don't have a choice in buying tires now...the ones on the car were put on in 1960.

it's getting real annoying to have to put air in them each time I want to move the chassis around, and with the additional weight of the drivetrain I doubt I will be able to just pick it up and move it.

Seeing you are not driving it why not put slime in the tires rotate the tire to cote the in side. I have done this a number of times and it worked well. Slime is not intended for road use.

4 brand new 205/75R15 are now on. Thanks for the help.

I even took the time to sandblast, prime and paint the rims. (metal flake emerald green with silver pin striping)

Total time 8 hours. Total cost $48. ($40 for 4 used tires, $8 for valves)
