Re: 325/50R/15 on a 68 ? Will they fit

This is a 295/50-15 on an 8 inch wheel on my Monte. The rear is narrowed one inch on each side and I added a 1 inch spacer to get the wheels centered between the inside and outside. It's a stock 15 x 8 rally rim with a 4" backspace.

I'm *pretty sure* I have enough space to go to a 325 on the same wheel. I may try.

I will have to measure everything out, which I haven't had time to do yet, the rear end is a QP 9, and I don't know if it's all stock dimensions or not. The good thing is that the QP 9 uses a relocated shock mount that places the shock directly above the LCA and is more vertical.

Thanks Joe

Re: 325/50R/15 on a 68 ? Will they fit

this shows how they (QP) moved the shock mount in, so one less thing to rub. I already had to mess with the the exhaust though, 3" pipes take a lot of room !

Thanks Joe

I just can't imagine a 325 tire on an 8" width wheel. Definitely not an optimum situation.

I agree with you Clint

As JEGs list that a 10" Wide Wheel is required for a Radial 325/50/15 Tire

that wouldn't have been my intention either, I was thinking a 10" rim for the 325 tire, which after reading, wouldn't work anyway.

Thanks, Joe

Re: 325/50R/15 on a 68 ? Will they fit

That is nice to have the shocks moved in. I have had a 325 on a 10 inch rim and it was still a little bulby. An 11 inch rim would have been perfect but nobody really makes an 11 off the shelf and a 12 inch rim would have been too big. A 12 inch rim goes well with the 345 tire. I have a 295 on a 10 inch rim and it fits perfect. Good luck on the project.
