I am considering buying a set of chrome alloy Cragar SS rims in 16x8 for my 68 RS with stock suspension. They only come in 4.5 or 4.97 inch backspacing. I was thinking of using the 4.97 inch backspacing in the front with 225/50/16's and the 4.5 in the rear with 255/50/16's in the rear. How does that sound? Does anyone have any better suggestions for the best fit?

Thanks!
Mike

I run 16x8x4.5 with 245/50/16's all the way around.....its kinda nice to have the ability to rotate.

The 4.97 will also fit but it would fit on the rear better without having to 'roll' the inner lip......and it might slightly rub on the frame rails up front.

Chicane, Are you saying the 4.97 backspace up front would rub with the 225/50/16's? How much room do you have in the rear with the 245's? Did you have to "roll" the lip? I really want the largest rear tire I can fit, thats why I want to go with the 255/50/16. I guess the 4.97 will be the best for the rear, its the front backspace I'm more concerned with.

Thanks!
Mike

I have the same rims Tom does but am running 255/60's on the rear and 245's on the front with no clearance problems.

Its nice to have the extra room with the rear well's of the 69 body as compared to the 67-68.

Mike- I think with the 225 on the 4.97", that you shouldnt run into problems....but with a 245 it would most likely rub on the frame rail in a full lock turn. So, I think if that was your choise, you'd be ok. I pulled the front spring and fully cycled the suspension with a 245/50/16 on a 16x8x4.5 and it didnt rub anywhere, so that is why I run that wheel/tire combo.

On the rear of my 67, the 245 on the 4.5" requires a little inner lip massage and I have tons of room to the frame rail. The nice thing with that is that I can actually fit a 9.5 wide rim in the rear.......because I have an 1" plus to the frame. But it would still include the rear lip to be rolled.

I am currently working with Rusty at Vintage Wheel to fit a 9.5 front and rear with no modifications to the front and with the only modification to the rear being that of rolling the fender lip. But that information doesnt really help with this.......but it is nice to know that it can be done.

Hmmm. Tom, what tire sizes do you have in mind on the wider rims?

Well I have three sizes to play with and I have to get the exact offset on the nose first. But the three are 25/265 and 275. I was initially thinking the 265 on the front and the 275 on the rear.

I have 16x8 wheels on the back of my 68 rs. They have 4.75 backspacing and i run a 265/50 tire on them, they do not rub at all. I don't know how much that will help you though, since you can only get 4.5 or 4.97

Thanks for all the replies guys. I'm going on a much needed Southern California vacation next week and when I get back, I plan on doing some measurements and hopefully will be ordering soon after that.

Thanks again!
Mike
