That's about where I get really nervous, just because that's the number on the tire, it doesn't say anything about the integrity of the wheel, I've had new ones, that were cracked, from the factory, something goes a little off kilter in the forming process, the material is compounded wrong, doesn't take much, I know this, it to me, is more nerve wracking than driving the car, that's relaxing. JMHO! Bob
