Tire & Wheel Recommendation

[Ricks70Duster340]

Am converting my 70 Duster to big bolt pattern rear axles & Dr Diff front/rear disc brakes. I like the original looking rallye wheels, and just want to ensure the wheels/tires I am looking at will fit. Stock 8 3/4 rear & spring locations. QA1 UCA with big balljoint & new big balljoint for stock LCA. Front wheels 15x7 with 4.25 bs and 15x8 with 4.5 bs for rear. Front tires 205/70/15 and rear 255/60/15. Want enough rear tire to plant while not modifying the fenders.

In the rear i'd be looking at a 26x10.50 sportsman pro

99% local cruise with street fun with a 408 stroker. Currently 3.23 but looking at going to 3.73

The backspace on the rims should work pretty well with your combination.

For the tires, the back should work just fine as long as the rear of your car is stock height or higher. A little more backspace would probably be better, but as long as you're not lowered that combination should fit most Dusters set up like yours.

In the front I think you may have issues with the tire height. Again, it will depend on your ride height but a 205/70/15 is 26.4" tall, and to be safe you should generally keep them under 26". A 215/65/15 would be 26" tall, a 225/60/15 would be 25.6", and both should work on a 15x7 with a 4.25" backspace and 73+ style mopar disks.
