i was just estimating with the 5cm, i havnt had the chance to ride my bike in ages
i wanted them because my mate had them on his 06 GT Chucker 2.0 and they were heaps good,
last really long, we were like going flat out, locking on the rears and doin 20 metre fishies and the tyre would barely loose any rubber. My tyres on the other hand last about 10 good skids before i pop them, which sucks.
But its not all about skids
the main thing is the wear factor
i want it to take the abuse that i dish out (on road, off road, tricks, skids)
but still last for a while
ill have a look at both of them next time i go down to the bike shop
