E-Body Tire Combos

[drewcrane]

i havent decided what will fit in the front,i might purchase a wheel measuring device so i can make it as tight as possible, stay tuned.............

No leaf springs.

No strut rods in the front suspension either.

They also use a rack and pinion steering set up, which I've heard has reduced wheel angle, so that helps reduce the prospect of scrubbing the wheel sidewalls inside the fenders.

humm now im thinking , does anyone have the rack & pinon set up? i wonder if they have a bump steer problem? that system would utilize a bigger tire in front

I just talked to scott at xv engineering , the biggest tire , and wheel combo they have put on a stock suspension., is 18x8 front wheel with a 245/49 /18., rear 18 x 9 265/40/18., cant put a 9 inch wheel in front there just isnt enough room! but this set up looks good

That would make sense for a stock suspension, although that is a tad small for the rear. I personally think you can go woder than that, even with leafs int eh stock location, but wheel choice becomes critical.

They have put 275 front and 335 rear using the Level 2 system under a Challenger. Not sure of the wheel size they are using, but it is in here somewhere. You can search for it by looking for posts from dqhemi.

Bump steer on their rack system is minimal. Since it is a completely fabricated system with relocated pick up points, they wouldn't have the same interference issue as a rack retrofited to a stock suspension.

  how much clearence do you think is needed in relation to the inside of the wheel to the rear to the leaf spring?

When i was sizing tires i believe the magic number was ~1/2" IF you are going with a thin sidewall tire. Going big tires on 15s and big tires on 18s is a different story on sidewall flex and clearances.

ah yes true 1/2 inch is goos i have that and then some and an inch or so on the out side so 9 inc wheel will fit,obviously you have it, so i will have to ponder it a little as to what i will do

Come on over to florida and try a wheel on. lol

[drewcrane]

well now theres an idea! :horse:i could

Are you set on 18" rims?

With stock suspension, if you run 17x9 with 5.5" backspacing rim in the front you can run a 275/40/17 tire up there. You need to have the flat type upper ball joints though.

See this site for 17" rim fitment: http://www.moparfins.com/CLAIRDAVIS/1969_front_end.htm

Here's a 68 Barracuda with 17x9 and 275/40/17 tires. If he can fit it on an A-body Barracuda, you can with your challenger. He had to cut/roll a ~3/4" by 3" triangle from the bottom front fender lip. www.conemangler.com

The 68 Valiant pictured here runs 17x9 and 275/40/17's also http://www.mrmopar.com/SpringFling2007/WillowSprings/

I did a Stainless Steel Brake Co. conversion on my front drums, and since then my wheels have dragged on the calipers.  They were some 15x7 aluminum mags with approx 4" of BS.  I have a set of Magnum 500's that do not rub, but they are 14x7 and the rubber is shot.
What would cause the 15" rims to rub the calipers, when my other wheels do not?  They have approximately the same backspace...
What wheel combo's has snyone used with success out there after a conversion to disc brakes?  I'm ready to invest in a nice set of 16" or bigger rims, but do not want to shell out the money only to find that they will eventually wear holes in my brakes!!

15x7 4"BS - 245/60R/15

I went safe and conservative....

Well, if they are an older set of mags,it is possible that they are drum brake wheels. Many moons ago before discs became standard on many cars, wheel manufacturers offered disc and drum wheels. It is possible to have identical back space, but a drum wheel will will have flatter spokes whereas a disc wheel will have some arch to it to avoid caliper interference.

Here's some pix of my Chally.  I'm in the process of changing some things, but nothing too drastic regarding the overall look.  However, I'm definitely changing the wheels and tires.  I'm thinking of going with with either 17" or 18" wheels.  Currently (from the previous owner) the wheels are 15" Weld Prostars (10" rear and 8" front).  Rear tires are BFG Drag Radials 315/60-15 (I think that's a 30" tall tire).  I'd like to go down in size by about 1 to 2 inches 'cause it's just too close to the wheel opening at the front side of the tire (about half an inch to an inch).  I can easily fit a 12" wide wheel (and tire set-up) in the back as the previous owner did a fantastic job of a 3" mini-tub with a leaf-spring relocation and going with an A-body 8.75 rear-end housing.  My problem has been finding a 17x12 or 18x12 that I like and a 28" or 29" tall radial tire that will fit the wheel width nicely without looking too much like rubber bands or balloons.  I'd certainly be open to the idea of staying with 15" diameter wheels as long as they're retro, muscle car looking and I can get them in 12" width, AND I can find a good looking tire.  I'd appreciate some help with wheel/tire options for my project too.  My preference in wheels is the Magnum 500s like those offered from Wheel Vintiques (billet and steel) and from American Racing.  Thanks
