Biggest Tires???????

Sounds like you may also need to re-center your axle within the body.

Good point. Thanks.

I've seen up to an 1" difference from side to side on a car with factory quarters and axle. If everything is centered and equal, 295 width will fit as @6PKRTSE has on his Challenger. Quality control wasn't very good on our E-Bodies unfortunately. 275 in the rear should fit in any factory E-Body, but if I remember correctly, someone posted they had more than an inch difference! So there's that possibility too! Sigh!

Up front I run an MT 26x10 tire on a 15x8 wheel with 4.5" backspace. Fits well. BTW, that about a 255/60 in metric terms.

I test fit a 26x12 on a 15x10 rim. Won't work because you can't get enough backspace to get it under the wheel lip and clear the control arm (control arm limits backspace to 4.75" with a 15" rim). You would need to significantly flare the fender to allow this to fit. However, if you go to a 17" rim, that diameter is larger enough to clear the control arm and you can run more backspace (5.5-5.75 inches) and have enough room to potentially fit a 295-315 in the front. However, back space and alignment have to be spot on and you will still need to roll the lip.

I do run the 26x12 on the rear.

Picture on the ground is 26x10. Pic down the side of the car is 26x12 on the front.

After giving it some thought and look at various other e bodies, I think part of my issue is I think someone cranked down the torsion bars sometime in the past. What is the easiest way to verify stock right height in front? Measure from the center of the hub to the wheel opening? If so, what would that measurement be?

Thanks,

Factory service manual will tell you how. It is quite involved off the front suspension. Best done on a alignment rack. I just adjust mine to where I like it and even it up side to side bu measuring the center of the wheel at the lip. It doesn't need to be rocket science.
