This is the bit that gets scraped across the tarmac going down ramps etc??
I've never replaced it, I just sand it down smooth again each time, probably 1/2inch thinner that it should be by now.
Jonm thanks for your response. That’s why it needs replacing due to my sloping drive and when I get to the bottom it scrapes
on the pavement.
I believe the replacement part number might be T2R4160?
