According to speedway motors for a dry,slick track you want 3" back spaces across the rear. my question is, how do you get them to fit ? We have to use towel city retreads. There going in a 78 metric

Dont understand the question but im going to take a stab at it, the rim is backspaced, its not the solid ones you put on under the rim. the backspacing is built into the rims and they should fit fine i use them all the time. Eddie

Yes they are the solid 3"BS rims but with the tire mounted there is even a 1/4" between the tire and the frame in the rear and I afraid its going to rub

Speedway motors AS$UMES that you will have enough clearance for even 4" back spacing. If you don't have the clearance go with either the 2" back spacing or a wider differential (if rules allow). But most of the drivers that run the stock GM metric rears use 3" back spacing with an eight inch wide tire and wheel with no problems. I'm not familiar with the towel city tires. You may need to put more info, (ie. how wide is the tire, the wheel, your differential) to get your answer.
