LM 20 tie?

[Pete]

What is the longevity of a Hoosier LM 20 tire? Time frame when to throw away or can you bring back to life by grinding and tire treatment?

[TheJet-09]

My thought on all LM's, but most certainly the 20, is that once the shallow "groove" built into the tread goes away (meaning the tire has worn that far), it's done. I don't run them past that because it seems the performance goes way down.

the 20 doesn't like heat cycles
