I went for a ride this morning (see, I'm not on Netrider ALL the time ) and a few kays from home the handling started to get real wonky. I thought the front tyre was going down, or pehaps I'd blown a fork seal. But I staggered it home, parked in the driveway and discovered a large builder's screw right in the middle of the rear tyre. I know this has been debated before, but I really don't want to have to spend another $300 when this tyre has only done 8,000 kays and has plenty of life left. What is the rules of the game with fixing radial bike tyres?
