my tyres have had about 3 'incidents' with the number plate - suspension bottoming out at speed - number plate rams in to the tyre. Now i've ridden on them for another 1000 miles but the cuts in the tyres are huge! (i'm pretty sure i can see material under the rubber

). Considering they're stock tyres with 5000 miles on them - worth keeping? or just waiting for a blowout?
