I was on the phone about to order my tires and wheels. The sales guy warned me about a tire this big on a 1967. Is anyone having major issues with a tire this size on a 17X9.5 rim?
No way a 295 is gonna fit if the car is lowered at all. Sounds like your car had a mean rake to it. I think he is going for the P/T looks and that means the car is either getting lowered or already is low.
Believe it or not the custom wheel companies suggest 5 and 3/8". If that's not available 5.25" or if the only option is 5 or 5.5 go with the 5.5. It's better to error on the inside than the outside.
275/40R17 or 275/50R17? I run the 275/50R17 on an 8" rim with 5" back spacing and it fits with lots of clearance. I plan to run 325/50R17s on either 9" or 9.5" rims when these wear out. This is on a 67 Firebird with a Moser 9".

i run the 275/40. are you sure you want a tire that's almost 30 inches tall? that's huge! you'll need a very low rear gear, too. you must be tubbed, right?
"Both the 275/50R17s and 325/50R17s are 28" tall."
the 325/50r17 cannot be the same height as the 275/50r17. with the 50 aspect ratio, 50% of 275 is not equal to 50% of 325. the tci calcualtors put it at 29.8 inches tall:
You may want to consider getting a rim with a bit more backspace than you think you need. It is a lot easier to add a 1/4" spacer than to have new rims made.
325/25.4 (conversion of MM to inches) =12.79. 12.79 + 17 = 29.79 tire diameter
275/25.4 = 10.83. 10.83 + 17 = 27.83 tire dia
You can also put the tire size, rear end and tranny gears into this calculator and it will calculate the tire diameter for you. http://www.f-body.org/gears/
And fwiw, I ran old Firestone 9.50/14 mud&snow tires on my car using my coil-overs and my stock 14" x 6" rims w/ 3.75" b/s years ago.
They measured like 29.5" tall!!
And I got an old pic of them on my car..
He, He!! Speedometer when from 70 to 82 mph at 30/3100 rpm!!
