295/65R15 M/T ET rim size

Seems like 8-10.5 is the rim-width range they call for; who's running what size? I've heard 10" wide is best.
Given the rearend width & leaf spring location (3/4" relocation brackets) that's with on this car (Duster), 10" wide with a 5" BS would be perfect, but that's a really hard BS to find; 4.5" avoids spacers, so that's next best...
(I've already pie-sliced the front of the opening, trimmed the wheel-opening flange, and rolled its upper edge, so I have 13.5" of wheelhouse width, and there's 6.5" from drum face to springs.)

I ran that size on my 12.0 inch wide Weld rims on my Duster with ladder bars and full tubs to the stock location inner sub frames, the M/T 315x60x15 ET street radials worked better on that car though

I have 295/65s on 10" Cragars. The edges are pulled up off the pavement with 18-20 lbs. I have to let them down to 12 lbs or so to get them to lay the full face on the pavement. And 12 lbs is too low.

What rims are you considering? Most companies will build your backspace on a special order. Cragar did mine.

You may want to consider the 275/60 Rs on a 10" rim. They would lay better with the 10" rims IMHO. The only reason I don't do that myself is because I like the look of those huge 295s on the back of the Cuda.

One of the decisions is do you want the tire diameter to grow (like you may run out of gear)?
If yes, narrower rim will get bigger at speed.
Otherwise, rim width = sidewall width is safe. 295mm = 11.6".

295 I would run on a 10 inch wheel minimum, a 12 inch would be better. I run 275’s on a 10 inch wheel and to me it’s a great combo....

M/T recommends an 8.5" wide rim for that tire, but most agree wider is better. I run 8.5" wide rims on my cuda w/ the 295-65 radial basically b/c of my stock width rear, a 10" won't fit.
Seems to work ok though. Best 60 foot footbraking on motor is 1.320. Best on nitrous so far is a 1.30 w/ a very delayed nitrous hit.

same size but hoosier radials on 8" rims. no problem

I run mine on a 10. It spread the tire out more then the 8 I used to run

I had them stretched onto my 12" wide rims at one time. I now currently have 315's & they fill the wheel well much better.

same tire on a 10" rim, contact patch looks good to me...

Looks small compared to the 315 or 325 I used run

Great looking pickup turbo!

I had them on a 10" rim on my Dart.

My 'Cuda has the MT 295/65-15 drag radial,on a 10" rim, 6.5" BS, stock width E-body 8.75, springs inboarded 3", stock wheel tubs, drives great, rides nice, mid-10 3800lbs.

Just for reference:

Man, you guys have some gorgeous cars! I appreciate the responses; funny that the only Duster so far is Cab's which is a very different animal than this car. I saw one Duster with 325s under it (!) but the guy didn't know the wheel size or BS.
Once I get the diff, axles & drums back in it I'll re-measure everything for the 5th time and maybe even fab a cardboard example to try to only do this once. Pretty much gotta go 15x10, just need to nail the BS.

I am shooting for a 295/65 on a 10" wheel on my Bee. My signature pic is 276/60/15 on an 8"(I think)wheel. I like the width of a 315, but I don't like the short tire.

I think that both of the sets of the M/T Street radials tires I ran(295x65x15, 315x60x15) had the same circumference when measure with a seamstress tape, but maybe not as that was a long time ago
I have 96.0 inch circumference for both in my mind, the 315x60x15 on a ten inch wide rim and the 295x65x15 on the 12 inch wide rims
I ran 4.10 rear gears in the car most of the time and I would see a 500 RPM drop switching from the 315x60x15 E.T. Street radials to the larger diameter 10.5x31x15W M/T slicks which had right at 102 inch circumference on the ten inch rims, no real MPH change in the 1/4 mile though that I remember, just RPM recorded on the VDO playback tach in the car

Turns out it was 315/50/15 that are shorter. 315/60's are 29.88 vs. 30.1 on the 295/65.

I run an 8" wheel. I know it's probably too narrow but it's what I can fit with the b body Dana and offset shackles. I'd like to go to a 10" wheel but I don't want to hack on my car..

I taped a piece of cardboard on the floor and then drove the car on it, positioning a rear wheel on it. Then I pulled the wheel and used a plumb bob to mark out everything on the cardboard.

The spring, hub, wheel well, etc. That is the most accurate way I have found to KNOW where everything is and to have a constant reference when researching wheels.

And be sure to do both sides to catch any differences.

I'm starting to wonder if I would be better w 275/60s (drop gear a tick) on 8s over 295/65s on 8s.

I have a B body Dana, 1”spring relocation kit from Dr Diff, NO Fender lip modifications or any other body mods and 15x10 5.5 bs with 295’s fit without rubbing under my 73 Cuda

I just run the 295 because it looks better than a 275. I do use a 275 at the track tho.

It seems pretty tight under my car. I may look into a 10" wheel but I can't see it fitting in there.

15x10 5.5 backspace fits my 71 cuda great with a b body rear and dr diff relocators. I ran a 325-50 with rolled lips before I took the car apart.
