Hi Guys, I was at a swap a couple weeks ago and picked up some m/t drag slicks cheap. But they are big will they fit under my 74 roadrunner. they are 29.5 x 10.5 and if they do what size rim should i use and what offset. Thanks

 

That is big. You'll need to run an 8.5-9 inch wide rim and maybe lif tthe back end a little to get them to clear. As far as BS goes, I'm unsure.

 

Tim is right on the wheel size.... On the BS there is a tool that you can install in place of a rear wheel and it will tell you how big and what BS you can put under your car... I have never used one but I have seen them in Jegs and Summitt..

Just remember that the more the BS the more you are moving your tire in....

 

OK Thanks, If I have to buy some different slick what size do you guys recomend for size 28x9 OR 8? Thanks again

 

What size tires are you running right now in the back? Do they have any issues with rubbing?

 

This is my first set of slicks for the car, I am running 14in. x 10 wide cragers with 24 in tires. Thanks

 

I don't think they would fit, unless the roadrunner has more wheel space than a challenger. A 10.5" M/T slick is actually around 13" wide.

I have some 60's on the back of my challenger that measure 10.4 with sidewall, and I have less than a quarter inch between the tire and spring, and a finger between the fender and tire.

I guess a lot less backspace and/or a thick spacer and the backend a few inches higher would do it.

Leaf spring relocation kits aren't very expensive, and would be the way to go.

 

Look for a 9' wheel with a +10mm offset.
Make two measurements drum surface to fender lip and then drum surface to leaf.
