E-Body Tire Combos

[dodj]

My '70 Cuda finally got her new set of shoes.  Hankook Ventus V12 245/45/18 and 275/40/18 with US Mag U111 Rambler textured gunmetal grey 18x8 and 18x9.5.  Stock spring location gives abut 3/4" room, fits inside the rear quarters with no rolled lips.  Fronts also fit perfect, no rolled lips, not rubbing on frame.  I will say if you have soft shocks you may hit your fender on a hard bump or pothole while on a hard turn.  I have Hotchkis Fox adjustable shocks and do not hit at all.

Nice stance dfrazz

Hey Guys,
I'm looking at a set of AR TT2's.   17" Nothing crazy but want a good stance and look.   Front/Rear disc brakes,  Strange 60-stock length  rear with 2.5" offset.  Back spacing ?,  should I go with neg/0/positive offset for this style rim.  The more I read this thread I get lost in all the combos.   But here was the combo I was looking at running. Front 17x8 4.07 -11/BF G2 tire-235-45-R-17.  Rear 17x8 4.81 +8/BF G2 tire 255-40-R17.  Any thoughts would be appreciated.

Will 295 60r15 fit on my stock 8 3/4 rear? 8 inch rim 4.50" backspacing

[crash340]

probably not, I have 295 50 15's on 10" rims 5.5" bs. with a 1" spring re-location and a B Body diff, and they fit,,,,, just, 1/8" fender clearance, and 1/4" to spring.
Wall to wall overall its about 12.5". a 315 35 17 measures 12 3/8" overall side wall to side wall

[Oddity360]

Ahh so my issue is width? I was hoping to get wider tires on the back than my dad's duster.....He's got 275 50s on 15x7 center lines in the rear...I might have to go with the same size tire I guess, I don't want to do any body or suspension modifications and I'll be going with a Wheel vintiques 15x8"rallye or 7" I guess if I'm going with 275's...Thanks crash...Maybe 285?

 I agree, a 15x10, 4.5 backspace on a stock E body housing, set up with 295/60s won't fit within the wheel wells.

I have a similar set up to crash340s but with slightly different results; '67 B body rear, 1" offset rear suspension. I'm running 15x10 with 5" backspace and a 26x12 (305/45 in metric terms) and I have about three quarters to an inch on each side of the tire. Of course, there are different width B body housings, so this can impact things as well. Mine is also in a Challenger. Rumor is Cudas are more stingy with clearance.

[Oddity360]

So then it's the tire that's the issue? I would be running 8 inch rims with 4.5" backspacing... thanks a ton!

[crash340]

Yes I couldn't run 5" bs, unless I rolled the fender lips but I'd also have to raise the height of the car. When I go to 18" rims, I'll go to 11" wide and prob 305's, maybe 315's as there is no sidewall bulge as such

I'm looking at Yearone Mopar Ralley wheels : 17" X 8" ; 4.25back space with a 225/55-17" BF comp tire. for  the FRONT of my 1974 cuda with original disc brake style. 9.20" sidewall width and 8.70" tread. The diameter is 26.80". speed W rated.
      Will this fit like a 245/60-15" since it's similar? @ 9.47" Sw. with 8" tread and 26.55" tall. T rated.

26.8" is a really tall tire in the front. It's not much taller than your 245/60/15's, but it might not take much to run out of room at that point. I try to keep my front tires closer to 26". I'd be more inclined to look for a 245/50/17, which would be close to the same 26.6" tall tire you've got now, or even a 235/50/17, which would be around 26.3.

You can go wider , a 255/45/17 would work too, that's 26" tall on the nose. I run 275/40/17's on the front of my Challenger with 17x9's and a 5" backspace. They're a little shorter at 25.7", and require a 9" wide rim, but a 255/45/17 would still have clearance all the way around on a 17x8 with 4.25" of backspace.

[Aracer]

The 225/50-17" BFG.Force Sport on the 8" Rally wheel will shorten up the tire, but still using the "Max. width wheel for any tire".
     Section width is still at 9.2", on a 26" tall dia. tread is 9", and this should be what I'm looking for @ $116.00 each.  Some sizes are not available in that price range. I'm getting them from Summit, mounted and balancing service for free. YearOne Ralley cast Wheels won't be in until Aug. 12.

My motive is to keep more rubber under me, than rim for ride and drag racing weight.  Thanks

Firestone Firehawk Wide Oval Indy 500, Firestone's Ultra High Performance Summer Tires on Year One Rallye Wheels Front 245/45R17 17"x8" 4.5" BS, Rear 275/40R17 17"x9" 4.5" BS
Both front and rear tires are 25.7" tall. W speed rating.
Zero rubs or issues front or rear.

ARACER -- I suggest you get the Year One 9" rims front AND rear.. 275-40-17 tires front and rear... you can then rotate them front-rear... no problems with that setup on ANY E-body.

[jimynick]

Sounds like good advice. Does that mean any non-modified E-body as well? Do you have a recommendation for a tire source for best bang for the buck?
