What would the following rim/tire combo look like installed in the back of a 1968 B-Body:

15x10 with 3.5in backspace, 295/50 R15 BFG Radial T/A

Would the tire be within the confines of the wheel well or would the sidewall protrude out past the quarter?

Pictures would be a great help. Thanks.

It will stick out over an inch... The wheel house is huge on these cars & with proper measuring a 10" wheel fits easily but 3.5 BS isn't it unless you plan to narrow the axle...

Axle is an 8 3/4
Hoping for a pic if it's out there.

With a 10" wheel a 4½" BS is going to put the tire at the inside edge of the fender well. your 3½" is not enough unless you are jacking the rear of the car up.

I run 10" steel wheels with 5,5" backspace and M/T SR 12/28-15. HD leaf springs in stock location on a Moser 60. Leaves 3/8" between springs and tire bulge. No rubbing. On my 68 Charger this was the biggest combo I could fit safely. Some say 5" backspace will work. On mine that would have put the tires too close to the fender.

I run 4.75" on my 68 as a 5.5 wouldnt even fit. I think they are all a little different. I have 1 1/4" on the passenger side and about 3/4" on the driver side on my car.
325/50/15 on a 10" rim dana all stock

This was beat to death about a week or so ago. The bottom line is that regardless of being a "b" body, it matters whether its a Dodge or Plymouth.

As was mentioned in that post, the Dodges have a little more room to play with at the fender and Plymouth rear ends are offset to one side so what fits on one side of a Plymouth won't necessarily fit on the other.

That said, I have a 10" wheel with 5-1/2" backspacing that sits nicely in the RIGHT wheelwell on my '69 Runner. However, after reading about the offset rearend I have yet to determine how it'll do on the left side.

May have a set of 10" Welds for sale !!!!

JACK IT UP!!!

(seriously, i miss that look...)

Anyways, sounds like someones got some old-school 10" rims. Had some 15x10" Vectors with about that offset, actually had 'em mounted on all four corners ov my 72 Charger (yeah, i know that doesn't help you) with 295/50/15's. Looked bloody mean, and didn't stick out too much. Undriveable though.

SOMEONE here has to have a set ov old school 10"ers out back on their B-body, with pictures.

I have 18x9.5's with a 295/45/18 series Nitto on it and 5" BS and I needed to clearance the 1/4s. IMHO 5.25" is the best but most manuf. only make 5 or 5 1/2". When I measured, 5 1/2 was going to be too close to the springs for comfort so I went 5. But 18" tires also have a stiffer sidewall and a more "square" tread so

Not going to happen inside of the wheel wells (with that offset) unless you narrow the rear.
