Interested in seeing what everyone is using for tire sizes. Please post pics if you have them. I plan on using 15" Torque Thrust, but plans could change.

Thank you!!

Likely not what you are looking for but............

M&H 390/45-15

I went with American Racing's Torq-Thrust II Polished 17X7 up front and 17X8 out back with Toyo PROXES T1R in 235/45ZR17 and 255/45ZR17

I tried 275 50 15 on the back and they wouldn’t fit. I ended up going with 255 50 15’s on the back and 245 50 15’s on the front.

65GP... those must be an odd tire size I'm not finding much of anything available!

Here is my son's 69 with 275-60x15 M/T drag radials on Torque Thrust IIs on the rear. IIRC the backspace is 4.50 and I had to trim just a small amount of the upper wheel well lip on the inside to give enough clearance. Fronts are 205-70x15.

Was thinking something like this night have a mean look on a street/strip car in a 255/60/15. For the few miles I put on, not worried about tire life or bad weather driving*

Speargun... those rears are maybe a little bigger than I was thinking, but curios on clearance... how much room do you have between tire and frame rail? Would a wheel with 4.5" back space still clear?

The Dana 60 in my car is about 2" wider than stock and I have plenty of clearance. I'm sure that a 275 tire would clear on your car without any issues.
IF the 275's were to rub on the frame, you can easily add a wheel spacer to bump them out a bit.

I'm actually looking at trying to stuff a 325 under the rear for my new set of tires.

Makes sense, I thought they were sticking out a ways

I have yet to order a new 9" for my car, and assuming I will go with a stock width. No rims yet either, so trying to line it all up and not do it a second time

I just double checked & I have an easy 1.5" between the tire & body.
And I'm pretty sure that the rims have a 4.5" backspace.
***Just measured & it's 5.5" backspace




Here's a pics that show how the tire fills the wheel well.



Looking down from the top, the tire is entirely under the well.


They look a bit wider when you get the angle just right.

I have 255/60/15's in the rear and cannot remember the fronts..

Just a quick follow up on this thread, I also had a conversation going here on a similar topic...

For those running a 275/60/15 in the rear on a 67/68, are we dangerously close to tire rub? I have heard a few comments to that effect. I am thinking a 255/60/15 on a 8" x3.8" backspace might provide a little room for error?

Right now my thought is the 255 on the rear and a 165/85/15 up front for the desired fat & skinny look.

Talking out loud here... feel free to share thoughts and experiences
