E-Body Tire Combos

[moparman82]

Hey mitch, your car looks bad a$$!  But just for kicks, do u have any more pics of that AAR?  "Johns AAR"?

[Mopar Mitch]

T/Anks for the compliments... I've got hundreds of pics of John Sandberg's SCCA Solo/autocross C/Prepared AAR... he and I met racing in 1975 (we had each recently bought our cars that same year) and became best friends...  we'd race together at lots of events (SCCA/related autocross) and were, hoensetly, always the two most popular cars there amongst typical 100-200 cars for local events.. and also the major Regional/National events.

John's son Sean has a 73 Challenger (red with white interior), 440-6, 4 spd, 3.91, 17x9 rims, 275-40-17 front, 285-40-17 rear, 4-whl disc brakes, T/A Fast Ratio p/steering,  Koni fully-adjustable Red shocks, de-arched SS rear leafs, 1.24" diameter torsion bars, all fiberglass front end, 1.25" front and 1" rear sway bars..... overall, the suspension came from the race AAR of his dad's car..... very similar to my suspension.   We're doing some occasional hi-speed track/lapping events.

Here's another pic of John's AAR..... he had painted the car black in the 70s and thru the early 2000s, then repainted original red ~mid 2000

Mmmm... Love the mini-lites.

Agreed. You know you can still buy original Mini-lites in any bolt pattern, size, and backspace you want. Unfortunately, they have no plans to expand their street product line into any diameters greater than 15".

Yeah, that's why I went with the E/T wheels instead.

16" are available.....

But at some point soon I too plan on these ones.

Yeah I may pick up some Team 3, 17"ers at some point because I think those are most representative of the originals. I just wanted to point out that original, genuine Minilites from England are still available if you are willing to stick with 15" tires. I had them price a set for me once and they are around $1200, for two 15x8 and two 15x10 with custom backspace, built, boxed, shipped to my door.

I just went to 18's on my car - 18x9.5 F and 18x10 R with 265's in the front and 295's in the back

did you mod anything in the back to fit the 295s?

hello,

maybe this is good time to ask for help in setting up my wheels and tires for my 70 cuda.  The car didn't come with any wheels/tires and the car is in the body shop.  So I would hate to wing it.  I want to use a steel wheel and have it painted the body color with the correct center cap.  I would like to use a 15' wheel and the widest tire I can of course : ) It has a factory dana rear if that makes a difference.  Any guidance or opinions would be greatly appreciated. 

[Mopar Mitch]

You want to try best to keep the factory centerline of the wheel/tire as factory located.  Here's the specs to follow:

factory 7" wide = 4" backspace
8" wide requires 4.5" bs
8.5" wide requires 4.75 bs
9" wide requires 5" bs
9.5" wide requires 5.25" bs
10" wide requires 5" bs
etc.

Reducing these dimensions will push the wheel/tire progressively OUT towards the fender (lips and wheel well.)  In contrast, increasing these dimensions will bring the wheel/tire IN towards the frame rails and rear leaf springs.

Your tire diameter will be a concern... keeping relatively low profile tires allows more outer fender clearance (lips front/rear, and wheel well in the rear more-so).  You'll have to decide if you're willing to, at least, tuck in the fender lips... the rears will likely need it more that the fronts... consider stiffening your suspension (torsion bars, leafs, etc) to reduce excessive suspension compression, as well as the body leaning under extreme cornering.

With easy-select 8" rims, or even narrower 7", having the above bs, you should be able to safely run 245-60-15 fronts (and even 255-60-15 fronts), as well as easily run 245-60, 255-60 AND easily 275-60-15s in the rear... all without tucking the lips.. except the rears for the 275-60-15 may like you better IF you'd tuck those rear lips a little.

Thanks Mopar Mitch!  I really do appreciate your help!  This info is going to be a big help.  gotta go, time to shop!

Anyone tried Bassett wheels?

I'm liking the 15" D-HOLE LIGHTWEIGHT WHEELS. I want to stay with 15" and around 60 profile for looks. The 8" rim should take up to 265 - yes?

Would the 10" rim fit under the stock rear without mods and if so what max size tire would fit do you think?

Do you know anyone with these rims? Cant find any pics so far, let alone max tire sizes on these rims.

I have typically stick with the tire width equals tread width approach, but that does give you some latitude for section width differences.

In my experience,  a 10" rim will not fit in the stock wells with out springs being moved, or using such a skinny tire it look silly.

Also, Bassets are not d.o.t. approved and they have 45* lug seats instead of the traditional 60* seats, so they require matching lug nuts.

I have similar wheels from Aero on my challenger. Look through some earlier threads and you should be able to find pictures, however mine are chrome.

In addition they are usually drilled for 5/8" studs too, standard in circle track.

[HP2]

Yes, that's true, I'd forgotten about that. I use 1" lug nuts on mine. That 1/2" thread in them looks kinda small compared to the 5/8 course thread the oval trackers use.
