E-Body Tire Combos

[Carlwalski]

OK, lets get a tire/tyre size combos thread started. Too many wasted threads about one topic.
Chryco if you or Ross or someone could sticky this topic that would be good.

Post what rear end you have, tire size, wheel size + back spacing etc
Also any mods or relocation kits that were needed to fit your wheel combo along with photos, definitely PHOTOS.


I'll go first:

1970 Dodge Challenger R/T
8-3/4 SureGrip

15x8" Rallyes Rear with 275/60 BFGoodrich Radial T/As
15x7" Rallyes Front with 245/60 BFGoodrich Radial T/As

Chrysler Rallye wheels: 56 Series purchased from www.jegs.com All wheels have a 4-1/2" (4.5) Back Spacing.
Rear trim rings leave a 1" gap due to the wheel being 8" and repro/OEM rings only available in 7" sizing.

No rubbing, no relocation kits, no worries. 

Cheers,
NZ440R/T

Panther Pinks Combo:

295/50 R -15 with little clearance to the leaf spring.  Fits inside the wheel wells though.

1972 Dodge Challenger
Centerline Autodrags rims and BFG T/A Radial tires.
 The fronts are 15x7's with 3-5/16" bs on 225/60/15's
 The rears are 15x8.5's with 4-7/8" bs on 295/50/15's
 ******NOTE: This is on a stock E body width 8 3/4 rearend, I HAD to use a 7/16" Mr.Gasket wheel spacers to give the tires at least 1/2" clearance from tire bulge to leafspring, because all it had was 1/16" to 3/16" clearance without them. I also installed 3" long ARP wheel studs and open end lug nuts in the back, so I'd have plenty of threads for the spacers*****
 ***So if you like this look and want to use a 8.5 wide rim just find a rim with a 4 1/2" backspace and you won't need any spacers! Yet it will look the same.
 It just barely touches the drivers side when I hit a big bump, but I'm still using stock shocks with re-arched leafsprings. If I added KYB shocks or rolled the inner lip a little or trimmed it wouldn't hit.

I have 275-60-15 MT drag Radials on 8 in ralleys now.. but i had MT 12.5 x 28 Street ETs on the same wheels on it before. Just had to use a half inch spacer.

Just put on new tires. Car is a 71 cuda--stock 8 3/4 rear with new espo 1" over stock height springs. To fit 275/60-15 tires I had to buy new  15x8 ralleye rims(from wheels vintique)  4.5" backspace. Front tires are 235/60-15 on stock 15x7 ralleyes.

Wonder would the new 18" charger wheels fit on a Challenger?

[Super Blue 72]

Here's my info for the 14" crowd:

1972 Challenger Rallye
Stock suspension, 8 3/4" rear end
Factory Mopar 14"x6" Styled Road wheels (Magnum 500 style)

Fronts: 215/70R-14
Rears: 225/70R-14 (a little taller and wider)

For the 14"x6" rim, from what I saw, the widest tire you can "safely" mount is a 225/70R-14 or a 235/60R-14 tire.
There's also a pic comparing the 2 sizes.

I'll go ahead and post mine even though I don't have them mounted yet and I don't have any pictures yet. But, here's what I have.

American Racing 15x7 AR23 Wheels all the way around.

BFGoodrich Radial T/As all the way around:

P215/60/15 on front
P255/70/15 on the back

  Don't you mean p255/60/15 on the back??? I'm hoping you made a typo there.

thanks for pulling mine over NZ, I also have a 8 3/4,  stupid question: what is the best way to measure backspace?

[pink panther]

also I'm running centerlines as well.

The way I did it (If I did it right!  ) is you can take a straight edge/ruler/rigid tape measure and lay it across the diameter of the rim on the lip then measure down from the straight edge/ruler/rigid tape measure to the mounting surface of the wheel.

Sorry to stumble on to this late, but did the springs have to be moved inward to fit these tires? Any more than 4 inch backspace or so, will give you trouble in an E-Body. You might get away with 4.5 inch max on a low profile tire.

MEKrunner unfournately I ordered the 255/70/15 series. Is there something wrong other than the difference from the 60 being 27 inches tall and the 70 series being 29 inches tall? I tried to order the 60 but, they were on back order for 2-3 months. Now you got me all worried.
