Thread: Rear wheel back Spacing

Tweet

46 chevy truck. Have noticed that any left turn slight to moderate causes a squeek, squeek, squeek. Nothing rubbing in the front. Found 1/2" to 3/4" rub marking on the rear tires. Tires are rubbing on the bed. This is from the side of the tire toward the first tread. S10 rearend. Back spacing of the rim is 3" and it has 1.25" wheel spacers. Assuming the S10 is user friendly for this application I am thinking the rear wheels were the wrong ones for the application. I looks like there is an 1" from the outside edge of the tire to the inside of the fender. Rims are ARE-550 17x9.5,tires 275/40 R17 98W. I don't think the solution is more spacing. What is the best way to approach this? As I look at these numbers it looks like I need an 8.5" wide rim or super deep dished rim??

The rim width is ok for that tire size, but sounds like too much tire for fender. Wheel tubs maybe?

We put a '46 Chevy pickup on an S10 4X4 chassis. The 4X4 rear is wider than your 2WD rear, and it works good with Rally wheels. The stock 4X4 wheels, which are offset to the inside to end up with the same overall width as the 2WD, will not work.

I was able to go to 1.75 spacers and solve the problem of rubbing. I also like the idea of the S10 frame swap. I want to drive it for a while before totally redoing everything. But I can start to collect parts now.
