i know this has come up before and i cannot find the e-mail. i am going to put new wheels on the cuda. they are going to match the front ones. how wide a wheel can i get along with what backspacing i need. also what is the biggest size tire that will fit in the wheel well. thanks!

I'm running 275's in the stock wheel well on my 65. I'm running 17 X 9 rear, and 8's on the front. I know not every one like's the 17, but I did it as they have a 5.94 back space and they clear the Wilwood disc brakes, the fronts are 225's

i am going to stick with 15" rims. there is 15x3 1/2 wheels up front. sounds like the 275's would work in the rear. i have stock drum brakes so the back spacing would be different?

i found the e-mail about tire and wheel sizes. here it is:



The most tire that I can garuntee a hammer and tin snip free fit on
is 225 50 15. Many are also running 225 60 15, which works as long as
they don't squerm too much. I'm running 245 45 16s on the '66 Dart at
to moment, but thats with trimming, hammering, and bottle jack work.

15" Wheels are 15"x7" 4" to 4.5" backspace (4" BS seems better to me)
16" wheels are 16"x8" -5" backspace (may need a spacer in the rear of
most early A-s, the Dart's rear is 0.75" wider thanks to its 11"x3"
rear drums)

On the 14"x5.5" wheels a 215 60 14 would be a great twisty road/highway
on-ramp tire. Another good handing tire/wheel combo (pretty short over
all hight though) would be 14"x7" -4" backspace with a 225 50 14 (Toyo
RA-1s are available in this size, very sicky, and tough enough to last
10,000 miles). You couls also find 225 60 14s.

This is what my rear wheel specs are:
Style: Bullitt Finish: Chrome
Size: 17x9 Centercap Size: Large (2-1/2")
Back Spacing: 5.94" (151mm) Offset: +24mm (0.94")
Bolt Pattern: 5x4.5" (5x114.3mm)
I do have my springs moved in as well.
Rear wheels are 164 each from here.

I'll try and get some pics tomorrow as well.
I think as long as you are running BBP 4.5 the offset would be the same for disc's or drum's (not redrilled small bp axles) Note: I have not driven the car, but I am building a track bar so the rear can't move around.

thanks for all the help keith. i'll check out the pics. the rear end is out of a demon, gear ratio 456. springs are not moved in so the 275's are probably out.

Here are some pics. The car is all apart again as it is getting primed right now. I took these pics when I first tried the wheels on the car.

Hi Guys, New here.....

Kieth, do you have 17 x 9's on the fronts also?

I'm thinking of going 18x9's all the way around...I just have to get the wheels off and do some measuring...I was just searching around and came to this forum...Thanks,
Jim

Jim I have 17 X 8 's on the front and 225 45 17's

The only way you can get the 17 X 9 's on the back is to move the springs into the frame. The wheel well is big enough, the springs are in the way by about 1 inch.

Thanks for the fast reply, I have the wheels off now...I have an 8 3/4 out of a 70 dart in mine. I'm looking at the springs and Did you relocate them to the inside of the frame? Because it looks like I need more of a 0 offset or 5.25 offset from a 9" rim. I'm looking to purchase wheels and tires next week...just want them to fit.

I have also the same rear end you have. I have changed out to yukon axles for the 4.5 bolt pattern and my rear rims have a 5.94 back space. The one tool that will help you decide the spacing of the rims is a Percys wheel rite.

This is worth is weight in gold when you buy rims you can't return!!!

Well I got the 255/40/18's on the front...no rubbing...Have not tried it on a track yet...I got 265/40/18's on the rear...but the driver side fender rubs the outside of the tire a little going around left turns....ticks me off that these cars are 1/2 inch off from the factory I found out...My Passenger side is perfect...I need to move the body of the car 1/4 " to the left/driverside somehow...that's all I need so it doesn't rub
66 Cuda...Doctor Diff Axles...Wilwood Disks all the way around..265/40/18 in rear..255/40/18 up front. 322 C.I. 3.23:1 Sure Grip 8 3/4...Just Painted it in my Back Yard...Primer flat white and Flat Black. My new Favorite Toy.

That's a lot of tire and wheel back there 66cuda. I like it very much.

I am quite interested in this, as well. I just bought 15x7 Torque thrusts for mine in the wrong pattern. The will fit on my AMX though. I am thinking 15 x 7 - 4" pattern with 4 3/4" backspace and a 245/60 tire should work on all 4 corners.

245 60 15's will be a close fit on the front. I originally tried a 245 40 r 17 and it was a little too big and went back to a 225 45 17. That little difference stop most of the rubbing on my front sway bar on full lock. It could still rub but at full lock on straight pavement it just clears.

Do you have a shot of the car showing the front and rears, Keith? I am really liking the look. What is the backset?

Here is my rim specs, offset is almost 6 inches

This is what my rear wheel specs are:
Style: Bullitt Finish: Chrome
Size: 17x9 Centercap Size: Large (2-1/2")
Back Spacing: 5.94" (151mm) Offset: +24mm (0.94")
Bolt Pattern: 5x4.5" (5x114.3mm)
I do have my springs moved in as well.
Rear wheels are 164 each from here.
http://www.americanmuscle.com/chbuwh17.html

I have an 8 3/4 rear with green bearings and wilwood disc's all round.
My car is in primer and I'm getting my frame connectors in, I'll post some pics when I get home, not sure what I have.
I'll also give you the front rim specs later as well if you want.

66Cuda has 255's on the front with no rubbing but maybe he has no front sway bar, or slightly different offset.
