Tire Speed Rating Question

I'm posting this here because the speed rating of a tire seems to me to cross all lines/types of vehicles.

Reading up on warranty issues/questions just now, I came across the following language w-a-a-a-y down the page at Firestone/Bridgestone tire FAQ's
Firestone/Bridgestone wrote:
The tire’s speed rating is void if the tire is repaired..... snip for clarity.....It should be treated as a non-speed rated tire.

That's repeated in the warranty published at this link (page 14)

What the heck does that mean?

  • It means that the basis used to give the tire a speed rating is canceled because the integrity of the tire has been compromised. You can no longer count on that information being true. It could fail at any speed and the manufacturer does not back up the original rating
