Joe!
The fronts are 26.5X8.5X15 and the rears are 26.5X10X15. They do have a full tread and it is deep.
The fronts will rub on full lock - If I need to turn that tight I just use the throttle.
They fill the wheel wells beautifully in my humble opinion - in fact the tires are what most car guys comment on when they see the car.
I got them from Carroll Shelby Goodyear in LA and they were $198 for the front and $202 for the rears.
So far I have a little over 8300 miles on them and they still have decent tread. I would do them again.
These are the same tread pattern that sprint cars use on their fronts - the sprinter tires are MUCH softer though and they only cost about $125 each for the fronts. (?)
