I know tony said they would fit, just bulge a little. But curious if anyone has done it and if they have a picture of how they look. I want the wider stance in the rear and I have 17x9.5 all around for my awd. I already have 275/50/17 street tires and want drag radials.

If you're just putting them on the rear make sure the tire heights are the same up front otherwise you'll destroy the driveline.

They will bulge, but I don't see a problem. I am running 315 30 20 Nitto DRs on my staggered 20x10 street setup and 275 55 16 M&H DRs on stock TB 16x7 rims for a rear drag pack.

I'm just asking cause they call for an 11" wide wheel on the site but thought maybe someone had a pic.

The m&h 275/325 are both 28" tall tires.
They are both 28" tall on the correct size wheel. Once you try putting it on a smaller wheel it will make the tire taller. I run the 275/50 and 325/45 m&h drag radials on 17x9 and 17x11 wheels making them very very close to the same height.

I didn't think about that. How much of a height difference you think? I know tony said no more then .3 diff in height for the drivetrain. Maybe less pressure in the tire would flatten it out a lil.

Then again it would also make it grab more in the rear then the front. I'll have to talk to tony when I'm ready to order.

They are already very close to .3 when used on the proper wheels. I don't think it will work on a 9.5 wheel. just run 275 on all four or get wider rear wheels

9.5 is fine, heck 275/50/15 fit on 7" rims on the GN's

They work but you cant run a 325 rear and a 275 front on the same wheel on an awd without causing issues

I just went outside to confirm the physical roll out on my truck with an undersized 325/45R17 up front (measures the same as a 275/50R17, because they are narrow) and a nominally sized 325/45R17 out back; both on 9.5" wide wheels. I have a 125' long driveway so I used the full length.

https://www.google.ca/search?safe=o......1c.1.64.serp..3.2.348...0i30k1.CINM3142KF0

Initially with 30psi in all four the roll out was off, not horrible, but noticeable.

Then I dropped the rears to 25psi and kept the fronts at 30psi, this demonstrated a very small variance in roll out front to rear.

Finally, I dropped the fronts to 25psi and the rears to 20psi and had the same (if not more) favourable result.

It is important to note that weight bias F to R will influence this, especially with such soft sidewalls. One thing I cannot account for in this testing is tire growth (I am unsure of the growith/stretch ratio for an M&H Drag Radial) at speed going down the track.
