Clubsprint Class
All vehicles entering the Superlap Clubsprint Class must run on Tyres with a UTQG rating higher than 100. Each competitor will have to advise the Promoter on their entry form which tyre they are going to use. If the tyres fitted to your vehicle have a UTQG rating under or equal to 100 you may be moved into the Open Class or refused entry entirely.

UTQG

UTQG is the United States Federal Government Uniform Tire Quality Grading Standard

While not really relevant to Australian conditions measure specified on the sidewall of most tyres.

The treadwear grade is a comparative rating based on the wear rate of the tyre when tested under controlled conditions. However this may depart significantly from the nor due to variations in driving habits, service practices and differences in road characteristics and climate.

The traction grades, from highest to lowest, are A, B and C, and they represent the tyre's ability to stop on we pavement as measured under controlled conditions and surfaces. A tyre marked C may havae poor traction performance. The traction grade assigned is based on braking (straight ahead) traction tests and does not include cornering (turning) traction

The temperature grades are A (the highest), B and C, representing the tyre's resistance to the generation of heat and its ability to dissipate heat when tested under controlled indoor conditions. Sustained high temperatures can cause tyre materials to degenerate and reduce tyre life.
