Umm...no offense, but I seriously doubt if it will get close to 140. Especially if it's stock. Manufacturers usually will put tires that have speed ratings appropriate to what the car is capable of or in most cases limited to. If the limiter is set to 130, then H (rated at 130) rated tires are used. Even if you can, I would not recommend exceeding the speed rating for the tire, unless they are high-performance to begin with and you only do it under certain circumstances. The speed rating is really a measure of the tire's ability to dissipate heat. My tire's are H-rated (Comp T/A's), and I wouldn't have a problem doing 140-150 on them for a short period of time on a cool day. I wouldn't try that on tires from Wal-Mart, though.Originally posted by: DaiShan
I will check again when it is light outside, maybe I missed something with the flashlight, it is an accord v6 btw (I know I know, but really I just want to know if there is a chance the tires will explode on me) Also the more you do it, does it wear the tires down more?
