Thanks to picking up some free roofing nails in the Home Depot parking lot this weekend and taking them home in the tires

I got to fix the leaks with four new tires

Since I have a spare tire now though, I did go with the Yokohama 740 GTX tires and already am enjoying a quieter, smoother and easier rolling ride than what I experienced with the Goodyear run-flats that came on it.
And I at least have the lifetime replacement warranty and 60,000 mile guarantee that $1260 will get you.
