I know ya'll are sick of this question but please help. I would like to use 17"x8" up front and 17"x9" or 9.5" in the back if possible without modifing. I will be using hotchkis springs 2" lower front and 1.5" lower rear. Will this work? What backspacing and what size tires can I use? Thanks for the help.
My brother in law had 17" Centerline Sabers on his 69. I think he had 8" up front with 245/45's and 9.5's on the rear with 245/45's. The backspacing is 5.5 on the rear don't know about the front. His car was lowered about the same amount. A set of 17"s will sure make it look good. As for me, I can't even begin to tell you how glad I will be when my 67 is ready for rims and tires.
first of all let me say that i now have the same suspension components you are using( hotchkis front and rear). i have done a lot of research and a 245/40-17 on a 17x8" in front with 4.5" of backspacing will fit! they are now on my car!
i havent done the rear yet but i am sure that 275/40-17 on a 9.5" rim will fit, only if you move the rear shocks completely inside of the springs and do some body work to the fender well inside and out. a 5" to 5.5" backspacing will be needed to clear everything. i am going to go with the 5.5" of backspacing and then use a 1/4 " spacer on the hub to make it all work. i think i may even be able to squeeze a 285/40-17 in there.
my project funds are gone for now but in the future i will let everyone know what exactly fit. good luck!
sorry you will have to do a little modifying to get this killer look!
Mark is right. Also, the inner wheelwell dimension on a '69 is 11-3/4". The section width of a 275/45/17 is 11". That leaves a mere 3/8" per side assuming the tire is perfectly centered. If the 285 is any wider - and of course it is - you may be able to wedge it in but it will absolutely rub.
I don't know why convertibles would be different - however, every car can be different so I'd measure yours first.
I'm running 245/45/17's on 17x7 wheels with a 4" BS on the front of my car and they fit fine. I don't think you can go bigger without rubbing.
In the rear, the consensus here seems to be that 275/45/17's will fit if they're centered. Some guys report a little rub going into a driveway or something similar that twists the car but they seem to fit if they're centered and the lip is trimmed and flattened. IMO, a 265/45/17 would be a great fit but I haven't found one yet!
I have been through this before on my wifes car. The 17/8 with a 4 1/2 backspacing will fit the front. The rear is best with a 5" backspacing. Any more and you will rub on the inside when turning into a driveway or any twisting of the rear. The 275/40 is the widest tire you can fit without tearing your car up. The tire size on the front is 235/45. I put 17/7 on the front of my car with a 4 1/2 backspacing and 17/8s on the rear with 4 5/8 backspacing. In my oppinion they look meaner than the larger ones. And you have more tire choices. One thing people forget when they get the huge wheels is you are limited to a short profile tire because of sidewall clearances. In my oppinion the 275/40 is too short and does not fill the wheel well at all. But thats just my oppinion.
