Post Tire Sizes

Hello, folks;

Question for you;
What is the biggest 15" tire size that anyone has run on the front wheels of your ride? I'm thinking about investing in some 15"x8" or 15"x9" rims and putting P255 60 R15 tires on the Cougar, but I'm not sure about interference problems. I thinkit should fit from all the measurements I've taken, but...
I know that P275 60 R15 tires will fit with ease on the back wheels, but I'd like to keep the tire and wheel size consistant on all 4 corners for handling purposes. But if anyone has successfully fit those fat meats on the front, what the hell! That'd be cool so far as I'm concerned.

As always, any help would be appreciated.

Mike

Well, I've gone and done it. I got 15"x8" wagon wheels and four P255/60 R15 BF Goodrich Radial T/A's for the Cougar last weekend. They look fantastic, and the handling of the car with these ample meats is simply fantastic! I don't think I've driven a car yet with as much lateral grip. Now, since the front springs are still very soft (I haven't gotten around to replacing them with stiffer ones; anyone have any idea where I might get stiffer ones from a junkyard application that I might be able to cut down, etc?), going over REALLY serious bumps the sides of the tires rub a little bit up in the inner fender, but its nothing a little creative hammering won't fix easily enough. :)
Also, since the front wheel isn't centered in the front wheel well, occasionally when I'm turning sharply and I go over a bump, the tire will rub the bottom radius of the rear of the front wheel well a little bit. Again, a little bit of bending here will go a long way. But overall, I'm extremely pleased to announce that yes, indeed, P255 tires do fit quite nicely on our Cougars and Birds. Let the rejoicing begin! :D
