Re: wheels and tires 72 swb road and strip truck?

It will be difficult to find a 15x7, with a 4-1/2 inch back space. You can get them by special ordering from some places, like American Racing. But, expect to pay a premium for them.

Most of the 15x7 and 15x8's will have a 4-inch back space. The 15x10's could have either a 4-1/2 or 5-inch back space, depending on the wheel.

I'm going with 15x8 6-lug Vette-style ralley wheels on the front, and the same style in a 10-inch width on the back. Plan to use a 275R60-15 on the back and a 225R70-15 on the front.

I asked the tech guys at Early Classic (where my suspension came from) about the back space that I should be running. They say that a 4-inch b/s is good for 15's, but anything larger in diameter should go to a 4-1/2-inch b/s.
