Switched tires to 70 series. 60s too low.

Looking good! What size wheels and tires did you use on the front and back? I was thinking about the same exact wheels for my GTX.

I went with 15x7's all around. 255x70s rear, 225 or 235 x 70's front. I started with 60's, but they seemed too small to me. 15x8.5's were too tight.

Hey cdp, i think you are correct about going to a 70 series tire.
Here's my 71 with a 15 x 8 Weld with a 275-60-15 tire.
Will a 70 series tire fit okay on an 8" wide rim?

Update: Got the RR out of storage this 9/11 weekend after about an 18-month hibernation. The 71 GTX engine rebuild last year got in the way. Working on some clutch problems and am actually going to get it prepped for a repaint. Too many flaws and some color die-back that bothers me. It is up and running. Sounds great with the CompCams XE274 cam. Anyone else have Mopar_ADHD that keeps them working on too many projects at once?

@76Beeper, yes, a 70 series should work fine on an 8" rim. I experimented with an American Racing TTO with the 255-70 on a 15x8.5, and didn't care for how the bulge was when inflated. It was really close to the wheel lip and just didn't look right, so the tire was remounted on a 15x7, and it worked great for me. My final tire is 255/70 rear, 225/70 front. My front clip isn't on yet, so its hard to see how it fills the wheel wells. The RR is equipped with 3.55 gears, but the drive ratio specs out to 3.23 with tall tire. Something to think about.

Currently, I have the same wheel set on a 71 GTX, same tire, but in 60 series and do not like the stance. IMO, the 70 series is the best combo.

Got my clutch squared away. Turned out that the clutch fork bracket was slightly bent back a little, not allowing the fork to fully engage in the throw out bearing. I went ahead and replaced the side cover of the transmission with a fresh one from Brewers Performance, installed an improved adjustment ball assy. from later model MaMopar, and pulled the clutch spring from under the dash to work better with a diaphragm clutch. Now I have full correct adjustments and everything is new.

Decided that there are a few paint issues I'm not happy with. A bubble in the door corner, a few chips, and a few light spots where full coverage didn't happen. Plus I'm adding exhaust tips and a cut-out valance. So, it will receive a full repaint over this winter. The shop said that they would install and align all sheet metal and decals. So, hopefully, come spring she will nearly completed.

Looks like a nice car to start with. I look forward to seeing some winter progress pics.
