Wheels

Three.
The UniSA prototype car used 14x5J 45 alloy wheels from a Suzuki Cappuccino, with 165/65R14 Michelin Energy tyres (the last three in Australia). The combined mass of a wheel and tyre was 10.6 kg.
Trev does not necessarily need wheels and tyres designed for 1–2 tonne vehicles. However, it does need:
- low rolling resistance tyres
- wheels and tyres that can handle side loads during cornering.
Motorcycle wheels and tyres are not necessarily suitable because they are not designed to handle large side loads, and they may not have low rolling resistance.
What do the Australian Design Rules require for LEP2 vehicles?
The wheels need to be easily removed for servicing the brakes and tyres, though this should not be required as frequently as on a heavier car.
We do not need a spare tyre—a can of tyre sealant will repair many types of puncture.
The (incomplete) table below indicates candidate tyres that are narrow and are claimed to have low rolling resistance:
| Michelin XM1+ | 175/65R14 82H | |
| Hankook enfren | 17 sizes, but smallest appears to be 195/60R15 | |
| Pirelli P6000 Powergy | 185/60R14 82H |
