Tire Size Help

Hey guys, thanks for the help in advance.

My a108 currently has 15 inch Cragar SS wheels, front is 15x7, rear is 15x8.

Tires on there currently

Front P205/60/15
Rear P255/60/15

I was trying to figure out what size to replace with. I want more of a rake, for aerodynamics.

For the rear, not sure if 275 is too wide, if 50 will look to small in the wheel well..

275/ 50 or 60 / 15

For the front .... dunno =S


Your expertise would be appreciated.

50's are wider than 60's, and a 275-50 is most likely the same height as your 255-60. Easiest thing to do is take a tape measure and see how tall your current tire is, 29", 30" whatever, then go to the summitt site and mickey thompsons are measured in inches for hieght. If I remember right the tallest one I was looking at was 33" and you could go from 10" wide on up depending on the clearence you have .

On my dodge I put 275/60/15 on the rear and they fill the wheel opening nicely!
The front I put 225/70/15 but I had to trim down the corners of the wheel opening.

Thanks guys for the advice!

I put 275 / 50 x 15 on the back and 195 / 70 x 14 up front.

Looks like a gasser

The 50 or 60 part of the tyre size is the percentage of the width so a 275/50/15 should be roughly 138mm tall in the sidewall , hope this helps,

BTW, a nice rake actually presents a larger frontal area, which decreases aero.
I always like a nose down attitude too.

OK...this might help.....

The wheelie bars are borrowed from my other car.....This tire set-up looks and works well, but I have to angle the seats back a bit so I don't feel like I am falling out the front.....

Sorry to bring up an old post, but i'm at the point in the project where I'm about to buy tires.  Here is a mock-up pic with an old tire from my caravan mounted on the wheel i'm using:



The above tire size is 215/70 R15. The van is jacked up with no engine.

My local Big O tire guy (and owner of an older Econoline) suggested a 225/70 R15 should be fine, but I'm worried because Slimtronn stated he had to trim the wheel well.
Both tire sizes I mentioned are the same height, but the 225's are just wider.
On the pic above, there is a 1.5 inch space between the tire and wheel well.

Slimtronn, how much did you have to trim?
Any comments are appreciated.
thanks
Edit: the pic was cropped so you can't see the space from the tire to the well, but it's 1.5 inches
