Does anyone have info about wheel well space in a 1964 Bonneville? I was looking at 15x7in or 17x7in American Racing 200S "Daisy" wheels but they only come in 4in backspace. Does anyone know if this will fit if i run a 205/60 (15in) or 215/45 (17in)?

Further complicating the issue is my car rides on air suspension and i dont want the car resting on the wheels (which will push on the bodywork) when it is aired out. Narrower tyres should help this but i am concerned the outer edge of the wheel will contact the inner face of the guard/fender

Currently i have 15in Cragar S/S with 205/60 tyres. I dont mind altering the rolling diameter (by running smaller tyres) as i will have to run a speedo adapter to suit the TH400 i have installed to replace the dead Super-Hydro 4spd.

You shouldn't need a speedo adapter. Both trannies are 1 to 1 in top gear.

What do you say about 15x7 wheels with 4,25 backspace and +6 offset
or 15x7 with 4,5 backspace and 0 offset?
Would any of them fit a 66 Bonneville with fenders and if so, what size of tires would be best?

I don't know from experience but my guess is they will work. Don't take my word for it though!

4.25" backspacing should work depending on the width of the tire and may still be tight. Don't think the 4" will work with skirts.

What's the backspacing on a factory 14x6 wheel?

I Have a 67 GP with 15x6 Rally's and 225/70-15 tires. Plenty of of clearance in the back on both sides. I just ordered 17x8 Cragar 69 wheels with 4.50 backspacing and 0mm offset. Will be using 225/60-17 tires. Same height and width. Should be no issue from what I can tell.

I hav a chance to get some nice wheels to put on my 64 Catalina but after reading this sticky I'm more confused then when I started. The wheels are 15 x 8 with a 4" back spacing. If they will work what tires are recommended

I'm ready to buy tires right now and am more confused than ever. Someone, my mind is slipping and I can't find the info, posted pics of his '66 (65?) Bonnie with 235/75/15 with 8 lugs and he says they fit wonderfully with no issue (with skirts). But from what I'm seeing here they shouldn't fit (or am I mistaken? I'm usually great with numbers too! lol)???

Anyway, I just want to get a nice wheel for the 15" steelies with poverty caps 15x6 wheels and can't figure out what will fit and look good. Will 235/75 fit? Or should I go to 225/75? 235 or 225 with 70%??

Thanks

I am looking to buy new 15" BOP 8 lugs, and some bigger tires, for my 65 Catalina. I am currently experimenting ... I put a 235-70-15 on a stock steel Pontiac wheel. There is about an inch of clearance between the tire and the 1/4, and a bit over 2" between the tire and the frame. These tires are 9.3 wide, and roughly 28 tall.
Hope this helps some.

I tried to get 235/75/15 on my car and they weren't even close to fitting (with skirts). I was thinking that because I have 4 wheel disc brakes added that if I remember correctly the brackets from Scarebird push out the wheels a little bit over 1/2" and that may be causing my problems.

I went with 215/75/15 ... and am wondering if I shouldn't use 215/70/15 instead ... I'll ride around for awhile with what I have and see how I like the look, feel, and handling.

**Revival**

My 1966 STARCHY has some 15x14" wheels & 470/43/15 tires
The tires dont have lots of room but are 31"x18.5”-15” and tucked in nicely

^ Yes, but it also appears your car has some serious wheel tubs.
