so im new to this site.... anyways i recently purchased a 1967 chevelle and it has a 1 inch drop, and in the front there are p225 60r15 and the back are p55 60r15.... now my main problem is the front rubs when turning sharply sometimes it rubs, and it rubs bad... my first thought was im getting brand new tires and rims soon, so maybe go with 14 in front rims with the same tire size, but then it would bring my exhaust closer to the ground, and the headers are already real close to the ground, what would the best thing to do

find out where it's rubbing first,do so by removing the tire and looking for marks.
sometimes,the inner center fender bolt gets in the way,doesn't sound like much but sometimes it's just enough.
sounds to me like the backspace is wrong...check with a straight edge across the edge of the wheel in back,I bet it's 4".;)

those are small tires and should not rub.

Welcome Jacob...
It sounds like you have the wrong backspace on your front wheels. You can easily fiy more than a 225/60/15 on the front of a 67.

I have 235 60 15s on the front of my 66 with no issues. Like Scott said, check out the databases. There is a lot of good info there.

the backspacing for the front is like 4 or 4.5.... what exactly does this mean

the more backspace you have, the closer the tire sits to the frame.

and it rubs on the very outside... theres cuts in the tires :( im almost positive its from the inside wheel well, on the 2 little bumps thats close to the bolt that bolts it to the fender thats the only thing that could cut the tire like that....

and just to be clear, when the car just sits, with no one in it, you can barely fit a hand inbetween the tire and fender

Three things could be going on here alone or in various combinations:

-it's a lot lower than you said

-the wheels do not have enough back space

-the alignment is really out of whack

The easiest to check is the wheel back spacing. Take off the front wheel, lay a straight edge across the back side of the rim of the wheel (not the tire!) and measure the distance from the lower edge of the straight edge to the place where the wheel mounts to the hub. For proper clearance, this should be about 4 inches. My guess is you have wheels with 3 inches or less of back spacing.

Man I literally just went through this same thing myself, I feel your pain.

I tried smaller, skinnier tires in front but it didn't help. My problem was also the backspacing on teh wheels. They sat so far towards the outside of the fender well, they were just not in the right place.

Had I picked up new wheels with the right backspacing, it would have fixed it. In my case, with a little "persuasion" of the inner fender well, I got the clearance I needed.

However, that's just a temporary fix. When I find new wheels that I like, I'm going to pick some up. I'm picky though, so finding some I like is going to take me for ever :)

I agree backspace on my 66 is 4.5 with 18" X 8" wheels and I could have/should have gone to 4.75. I put 1.5" lowering springs on the front which made it even tighter. They only rub when I have 4 people in the car and turn into a drive way at an angle.

If I had more backspace they would not rub on the outside, and if they were to rub on the inside it would only be during tight turning and rubbing a much smoother spot on the frame or suspension.

Many have changed the fender bolts to button head bolts to give more clearance and make it less likely to cut a tire if it does rub.
