With all the metal work done on my Duster and a limited amount of body work to complete, it’s time to get serious about wheel and tires. I prefer to run a staggered wheel tire combination, but am open minded. I just have a real personal problem with running a really wide tire up front. I’m probably going to run a Bullet wheel and really like the American Muscle matt black wheel as my car will be painted bright white with a matt black 340 stripe and the V24 blackout hood. So here is what I’m thinking for a serious street handling 6.1 Hemi Duster:

1971 Duster, 6.1 Hemi, Passion 4-speed overdrive

Front: 13” disc brakes on ’73-’76 spindles
Hellwig 1.25” 55907 tubular sway bar with either 1.00” – 1.06” Torsion bars from Firm Feel
Bilstein shocks all around
Custom rear springs from Peter Bergman lowered 1” with Dr Diff offset A-Body spring hangers (42” on center)
68-70 B-Body 8 Ύ” 60.5” wide with Dr Diff 11.7” discs

Combination #1 26” tall:
Front: 225/45-18 on a 8” wide 5.7” backspace / 30mm offset
Rear: 255/40-18 on a 10” wide 7.3” backspace / 45mm offset (Is this wheel to wide?)

Combination #2 25.7” tall:
Front: 245/40-18 on a 9” wide 6.2” backspace / 30mm offset (Is this wheel to wide for the front?)
Rear: 275/35-18 on a 10” wide 7.3” backspace / 45mm offset (Is this wheel to wide?)

So tell me what you guys think!

I would run a 18x9 and 275/35/18 minimum on the front.

245/40/18 on a 9" fit easily on my car. I am running a 255/40-18 (26") on a 9" wheel on the front but did some subtle alterations to the wheel arch for extra clearance. My car's sheet metal is different than your's, so you will need to look to fellow Duster owners or sort it out on your own. Get w/ Uhcoog1, he is in your area is he not?

I've been running 245 45 17s on mustang bullets all around on my duster. After a while I thought they looked too small on the back. I have factory 11 3/4" discs I'm not running a spacer on the front, and they rub just enough on the frame rail to take off the paint. I guess at bump and full lock.

Michael,

I've driven Wade's Duster and spoken with him and Alex about my build. I’m fortunate to have these guys in my backyard as they have both been very gracious with their time.

For a staggered setup, combination #1 would probably not require any modifications to body work and would look closest to a stock type setup. Question is, do I need 10” rims in back and how much cornering ability do I leave on the table with a 225/40 front tire?

I think combination #2 may also fit with just rolling the quarters and fenders. I’m also not sure if going with a staggered approach is going to create massive understeer that can be corrected with a rear swaybar.

In the next month I intend to mockup the front and rear suspension before paint and determine what will work best and if any modifications need to be made. I am also going to roll the quarters and front fenders. If we need to cut the front fenders I’m going to follow the method you described in your post on Moparts as it looks almost stock. Y'all need to update your picture as well!

Brian

"a real problem" running wide front tires? Is this personal, or space limited?



Based on your bold editing of "personal" I surmise for clarification, not sure I can offer much advice to resolve your situation.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

5.72 back spacing, I think 8" wheels. I ran a stock a body 8 1/4" that required 1" spacer/adapters, a 1970 b body 8 3/4 that fit good, and now an explorer 8.8". I'm going to wider tires on the back and I'm not sure what axle I want to run next.

Better balance with square
Staggered size is for 60-70's look and for drag racers, not road racers.
