I can't tell... I just bought the car, so the tires could be from anything. The manual says that the regular escort should run a 175/60 r15 not 165 and the GT should run a 185/60 r15 and I have 195. It is a constant noise, but I can't tell if it's more when I turn (because the exhaust is being replaced too) or if there is wear because the tires are new. I can see, though that without anyone in the car, I can see the bottom plate of the spring (is it the strut?) is VERY close to the tire and if there was play of about 1" it would rub. I assume my weight makes it drop that inch.
