I have a 69, stock, 205/70/14's. I am about to purchase rims and tires. I have looked through a bunch of threads here, but I am looking for a definite yea they will work or no they won't. I am definately new to the car restoration business, but it is a fun hobby.
I am thinking this setup... will it work with no rubs???
Firestone Firehawk INDY 500
Front 235 60 15 with CRAGAR SS 15x7 4.125 BS
Rear 255 60 15 with CRAGAR SS 15x8 4.125 BS
or do you recommend 15x7 all the way around. I simply am wanting a good look with no rubs and no mods required!!
thanks

The 235 in the front may rub. But with a 7 inch wheel you might make it. The combo I've been using is 255 in the rear 225 in the front. BFG's of course. 60 series.

AsRick said, the 235's are 1 size beyond "definitely yea" and just slightly into "probably" territory. Rim width and offset are perfect.

For the rear, I'd MUCH rather see a 4 1/2" backspace.
The 4 1/8" puts a 255 tire in the "Probably" range, and a 275 in the "Nope" range.

Gregg...

I run BFG 225-60-R15 on the front with a 15x8-4.5 rallye wheel and it rubs on hard bumps and turns. I have disks up front and that extends the tire outwards about a 1/2 inch. To prevent any rubs, I suggest that you go with a max of 225-60-R15 and best with a 215-60-R15

To me, the best way to test this is to use the actual rim you plan on using and going to the local used tire shop or bone yard and getting one of the tires you are planning to buy new. Mount it on the rim and drive around town trying it out. If it rubs, drop down to the next size. The used tire shop may work with you if you tell them of what you are testing. Spending 25 bucks on a used tire to test sure beats wasting a few hundred on tires that you can't use.

THANKS FOR THE QUICK RESPONSES!!
So if I go with 15x8, I should be safe to go 225 60 in front and 255 60 in the rear, IF I can find the CRAGAR in a 4.5" backspacing????
THANKS AGAIN!!!!

As I said before, I am a true novice!!
To be safe, I think I may go with 225 60 15's all around and 15 x 7's as well. I can't find the cragar with a 4.5" backspacing or I would try the 235's all around.
With the 225 60 and 15x7's I should be good????

I think a lot of this also depends on the shape of the springs. My rear mono leaf is original and pretty soft. If I have a couple of people in the back seat it will rub going over big bumps on the freeway and my rears are only 245/60/r15. The same size would be no problem if the springs were new. I am going to upgrade to the Hoskins sport springs for the rear and though the car will probably sit just as low they won't rub because of the suspension being stiffer. I have 215 in the front because of the car having been lowered.
