I would say that for street use and as much stress as could be aquired durring street use, the plug should be fine. But, I would not recomend tracking the car with that tire on it. Also, I have been told that certain plugs are rated for different speeds... you may want to look into that. Last but not least- I would recomend ANYONE here to get a tire pressure monitoring system. they are only 300-400$ at any GoodYear dealership Incl. installation. It saved me a few times on my VR-4 from leaking valve stems... and with these low-profile tires, it is very hard to notice a low tire.
