I want to stuff as much tire under the back of my 89 notch that i can without having the tires stick out and without tubbing it. I need to know what size rim/what backspacing and what size rear tire i can fir under it. Im going to put 15" weld draglites, need to know backspacing and tire size, basically thank you for any info

i had a 10.5x26inch micket thompson on my draglites with a 5.5 backspacing and they would rub if i went around turns to hard...but were driveable...and they didnt stick out of the fender...if ur using a street tire most people do like a 275/50-65/15s.

I have M/T drag radials in 275/60-15 and they barely fit with my Welds. I had to roll the wheel lips and tap the wheelwell a little on the drivers side. Are you still using the quad shocks?

I have 15x8's with 5.5 backspacing with a 275/60 drag radial which is almost the same size as a 28x10.5 slick. I had to hammer the inner wheelhouse a bit. If you want to use a 28x10 rim you need to get 6.5 backspace.

back space is the measured from the back of rim where it bolts on, to the inside lip of the rim. so the more back space you have the more rim you have under the car.

do these guys cars had 15x10 rims with the 6.5 back space? If they had a wider rim with that backspace it would do that. I'm not an expert on this I'm just going from experience. I have the 15x8's with 5.5 on mine and my friend has 15x10's with 6.5. It makes sense to add the exta backspace b/c if you go to a wider rim you would want to get the extra width under the car and not stickin out the side of the car.Look at my pics in my album mine don't stick out at all.

I almost regret getting the 15x8's now !! My friends car with the 15x10's with a 28x10.5 tire looks bad ass. You get less of the sidewall buldge in the slick with the wider rim.

theres going to be a big debate about this im sure. i like UPR. or maximum motorsports. i will only use the pivot ball control arms. some like the southside lowers or the mega bite jrs. just make sure if your running any kind of drag radial or slick you get torque box reinforcements. i run adjustables but they arent mandatory.

I have Weld Prolites (15x8 w/ 5.5 BS) with 275/50/15 (26") MT ET Street DRs on them......would you be interested in them? I've also had 275/60/15 (28") on them before and they fit fine. PM me if you're interested.

275/60/15 M&H drag radials, 15x10 draglites 6.5 b.s. didn't have to do any banging or rolling of the fender lip. I do have coil over shocks, no quad shock and Wilwood disc brakes. It will look the same with a 15x9 draglites with a 5.5 b.s. just more room as i have them new in a box used for mockup. If you are interested let me know.









with M/T 28x10.5 slicks
