Hi, what about Avon slicks.
I have currently 8x17 ET15 MO,s 9/23.3 x 17 avon diagonal. This year 2006, slightly bigger 230/620 x 17 radial.
Air temp 30 deg, track temp 35 - 40 deg.
Race distance between 2km and 4km.
Tyres checked when warm, not hot. (2-3 mins after run). In fact due to short distance the tyre temp does not get hot, probably not to full working temps during some runs.
Front 28.5psi
Rear 27.5psi.

Could this be contributing to my slight understeer?


always looking for advice from others with more experience.

cheers.
