E-Body Tire Combos

[miketyler]

I'm running Mustang fitment. Am running 275's up front and 315's out back. I had to install the DrDiff spring relocation kit but it all works. Wheels are Torque Thrust II's 

Fronts: 17x8 w/4.75BS and 275/40-17 tire

Rears: 17x11 w/8"BS and 315/35-17

Here's Dr.Diff's E-Body 1" offset hangar kit; using a motorcycle jack to install a 1968 B-body 8 3/4" housing. I also snagged the lightened spool from him ($85) on Ebay. Now, the 275-60-15 (10.5" Section width) Kelly radials leave  1.3" room @ the leaf. The Hoosier Drag (29x10x15") slicks on 8"x15"Weld with 4.5" back space, are 11.9" wide and will leave .6" room @ the rear leaf. But once you let the car's weight onto the slicks they fatten to leave only .3" to .5", so the passenger side needed the 5/16" spacer. This loaded carrier is 60 Lbs., stock housing is 40#, the axles are 20# each with 3" Mopar Perf. studs, total 140#s plus the brakes. Moser's housing's 60# bare. I went for less weight on this one, with the 741/ 3.91 ratio. Front tires are 215-70-14" on old 6"slots for now.

Has anyone looked at the O E WHEELS company? They have rims called morxchn mustang bullets that look awsome with the 17"/ 9.5"  5x4.5 mustang pattern with 5.94 bs. Will these fit my challenger with stock susp. Thanks for the help..

Not without spacers... From everything I'm looking at 5.5/5.6" of backspace is tops for a stock rear, probably a little less (~5") in the front, especially for a 9.5, probably less even in the front...

At this point I would say the car is finally done.  I just got the new wheels/tires mounted as a belated Christmas present.  The wheels are AR Torque Thrust II, 17x7 front and 17x8 rear.  The tires are 235/45-17 front, 255/45-17 rear.

They look great 73,  plenty of clearance there.  Now you can drop the car 2" or so and really dial in the handling.

TT2s are such a classic look, hard to go wrong with those.

Quick question for everyone.  How much room do you need for clearance to the 1/4 panel lip and also the leaf spring?  I was thinking like 1/4 inch each?  Does that seem about right?

[72bluNblu]

a 1/4" is pretty tight. Somewhere between 3/8" to 1/2" is probably a better bet if you want to avoid rubbing, keep in mind your tire profile changes under certain driving loads, and the suspension can move a little in relation to the body during cornering.

on the quarter panel side.  I would think the leaf spring side could be run down to a 1/4" or so.  I don't think the side wall is going to flex a 1/4th of the way around the tire from the contact patch to cause an issue on the inside.

Depends on the sidewall height.  If they are 15" wheels with 60 or 70 sidewalls, then they could flex that much in a hard turn, but under normal driving, probably not a problem.

Check out these 29"x 10" slicks, on Weld 15"x 8" with 4" back space. There's room for taller ones too, provided you use SS springs instead of the 440-6 pack pair shown here. That third spring clamp on the driver's side had to be removed for clearance . Removal, helps limber the leafs for "rise".
     The slicks and wheels are 40# each, and the springs are 35#each , so 150# plus the 140# for the loaded housing and the brakes @ 50# for a total of 340# "un-sprung weight".

Front 235 60 15's
Rear  255 60 15's

backspacing is 4 inches.....i think, bought them used, never measured

No modifications

Those look fantastic!  Love the color on your car as well.

Those wheels look sweet!!   

Not overly done. Just fine.

I run mine about a 1/4" (45 series tire) on the leaf spring side and they don't rub. I would also agree that a taller 60 or 70 series tire might need more side clearance.
