quick fitment question

[.mazda.speed.]

I also posted this in the protege section but it does not seem to be very active, someone here may also be able to help me out.

I bought a 99 protege lx for a winter/commute car.

I had some wheels laying around I want to throw on. I am not sure if they will fit and what size tire to go with.

The car has stock suspension with lowering spring, 2" drop.

Wheels are 15x8 +15 offset. I dont mind streching a little bit.

Has anyone ran a 15x8? What size tire will I need ot fit this?

Thanks,
Justin
