When good tyres go bad. :(
Sunday at Mt Wellington was fine and just great for racing but the ESE boys were complaining amongst themselves that their tires have gone off and that they were just not getting the grip that they needed. This was messing with their heads and they just did not have as good a day as they had expected.
Later when I read the bit below from Keith Codes book it occurred to me that the last couple of meeting had been wet and the tyres had become polished up and what they needed was a jolly good thrashing to get them working again. But everyone thought their tyers had come to the end of their life so they rode around like nannies. :baby:
From “A TWIST OF THE WRIST” by Keith Code
""Tire sliding and slippage are built-in safety valves.
They’re telling you the tire is reaching its limits. Premium street tires and racing tires are designed to operate in this area of friction and heat. The used-up rubber “balls up” and goes away, exposing a fresh rubber surface to the pavement. A standard street tire usually will not give up the used and un-resilient rubber fast enough, so it’s top layers become dry and slippery. The “oil’s” that are used to keep it resilient have been “cooked” out of the top layer of rubber, but the layer still clings to the tire. If you’re not letting your racing tires slip, you’re really riding under the ability of the tires.
Buying racing tires that are beyond your capabilities as a rider will not allow you to experience how tires perform at their limits.""
So if your tyres go bad give them a good thrashing, this works well for wives, dogs and children too. :zzzz: Just checking to see if the PC brigade is awake.
It explains why I have some times thought my tyres were dirty/oily and after a few laps were working ok, I thought they had just cleaned themselves up, in a way I guess they had. So if your tyres are slippy, thrash them untill they become grippy. ;)
