Question BIG tires on my 67

I'd love to use a set of 285/70-15's on the rear of my 67. I've seen it done but can't remember if there is any rear diff modification!


Please advise & thank you,

Problem is the Panhard bar shoves the axle into one fender well or the other as it moves up and down. Biggest I have seen is a 275R60-15.

I have a 67 Impala SS. For a while I ran 295/65R15 MT drag radials on a 9" wide rim. The specs for those are: 11.8" wide & 30.1" tall. Those tires don't have a good reputation in the rain and I wanted to go on some longer trips. So I switched to 265/70R15 BF Goodrich street tires on the same 9" rims. They are: 10.7"wide & 29.7" tall. Still fill up the wheel well pretty well and no rain worries.


The 285/70R15's you want are 11.5" wide & 30.8" tall. So the width will work, but because the front of the wheel opening turns back, I would worry about the big diameter hitting the wheel opening.


When I had the 30.1" dia MT's that area was too close for comfort.


AND, I also took out the spring pocket bump & replaced it with a flat piece. That gave me an extra 3/4" room on each side. I also rolled the fender lips.


You need to do some serious measuring.

I wonder if they still make a 265 70 15.

I did put my 275 60 15's on it and it looks pretty good but I still would like a larger Tire.

275/60R15's are: 11.0 wide & 28.0 tall


265/70R15's are: 10.7 wide & 29.7 tall & yes they still make them.

Yes but who makes them for a passenger car?? All I see is that size for truck tires. I wish they made that in a T/A Radial.

What back spacing on your 15x9 wheels?

5" B.S. They are chrome old style steel Corvette ralleys. Originally 8" wide. Took them to a wheel shop to get them widened 1" with the B.S. I wanted.
