TIRE & WHEEL MAINTENANCE
NOTE: Due to a wide range of driving conditions and techniques, tire maintenance will vary.
▪ Ariel Atoms are equipped with ultra high performance, wet/dry (not all-season) tires. Tire sizes are:
Front 195/50R/15 or 205/50R15 Rear 225/45R16 or 225/45R16
▪ Front tire pressures of 18 PSI, and rear tire pressures of 20 PSI are the recommended tire pressures for
most applications. Minimum and maximum tire pressures are listed on the sidewall of the tires.
▪ Drivers should inspect tires for proper pressure and tread wear before every track event. A wide range of
wear patterns are possible due to different driving conditions.
If you are losing traction it may be time to change the tires.
Suspension settings may affect tire wear patterns.
Grainy tread may indicate a suspension issue.
▪ Tires may last up to 20,000 miles (32,000 km) under conservative driving conditions or as little as 300
miles (480 km) for track conditions.
The wheels should be re-torqued before every track event. The lug nut torque is 80 ft-lbs.
Most Atoms have different size tires on the front and the back, and cannot be rotated. If you car’s tires are
the same size, rotate them every 500-1,000 miles (800-1600 km). Dismount the tires from the wheels
before rotating them.
