AvonTires, Michelin on 15 for 71CUDA

[automate33]

Hi,

I would like to install (AVON CR6ZZ or Michelin TB5 or Michelin TB15) 225 or 235 tires in the front of my 71 Cuda, and 285 or 295 in the rear.
I plan to choose 15' steel wheels but I have to choose the right backspacing so the tires fit in the wheelwells.
What wheels do you advise me to order with these tires, to avoid rubbing ?

Thank you

The maximum backspace you can use with a 15" rim is 4.75 inches. Any more than that and the rim will hit the upper ball joint on the front and it will be just short of touching the rear portion of the leaf spring in the rear. With a tire mounted, the sidewall will just touch the spring.

It may be more common to find 4 inch or 5" backspace. 4" would bolt right on, 5" would require a .25" spacer and longer studs. 4" backspace will work fine up front with a 7" or 8" rim and the sizes you are considering.  In the rear, 4" would be marginal for 9.5" and probably not work for a 10" rim as this may have wheel lip interference with 295 tires.  Of course the width of the lip on the rear opening is also a factor in this.

For what its worth, I run a 26x10x15 on a 15x8 with 4.5" backspace on the front of my Challenger.  On the rear I have 26x12x15 on a 15x10 with 5" backspace. I have rolled the fender lip on both the front and rear openings and I had to relocate the leaf spring inboard 1" to fit the rear.

On Challengers and Cudas, the leaf springs are not parallel. They are splayed wider in the rear shackle mount than they are in the front hanger mount. The limiting factor will be how close you get the tire to the leaf behind the axle. In front will always have more room.

thanks.

I will go with Michelin TB5

Front 225/50/15 with 8'' rim
Rear 285/40/15 with 10'' rim

Where i can find wheels with correct BS?

Run wider front tires.

I ran 225/50/15 in front on my 68 Barracuda and they looked small in wheel house.

You can fit 245/50/15 with 15x8 and 4.5 backspace.

I did that on my 68 Barracuda for years. The tighter clearances than your 71 Cuda.

   225/60/15 is short (225/50/15 would be way too short)   

& you might want to rethink those 285/40/15s for the rear      at only ~24" tall, that's awful short for an E-body (a stock F70-14 is ~26.5" tall)

unless "WE" are talking 285/40/18?         by the way, what country are you in?

& if these tires are for the FT6 V1G T/A in Switzerland .........  how's the restoration going?      missed the '71 'cuda part   

stock was 15x7.0 on all four corners with E60-15 (~225/60/15) front & G60-15 (~245/60/15) rear
and you could put lots of tire on the stock 7.0" wheels

  leave the 7.0" on the front with 235/60/15 & 8.0" on the rear with 295/50/15

if you want your 8" & 10" wheels - go for it     but spacing is more critical

it doesn't look like either of those Michelins TB5 or TB15 are available in a size compatible with an E-body - the tallest at 625mm (24.6")

& here is what I found on the Avon (old school rally tire)    that 275/55/15 looks like a nice fit for the rear

[HP2]

I tend to agree the Michelins are a tad short and will look small in an E body wheel well.  The Avons do have more compatible sizes that will look better. The 275/55 and 245/60  would be a nice match.  Not sure about pricing in Europe, but Avons are nearly $500 each in the US. I was thinking of using them until I priced them.

Wheels can be found from multiple sources depending on if you want stock appearing or aftermarket.  You local laws may also be a consideration for what you can or can't use. This may impact tire choice too.
