TIRE & WHEEL MAINTENANCE
NOTE: Due to a wide range of driving conditions and techni ques, tire maintenance will vary.
Ariel Atoms are equipped with ultra high performan ce, 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 pressu res of 20 PSI are the recommended tire pressures for
most applications. Minimum and maximum tire pressures ar e listed on the sidewall of the tires.
Drivers should inspect tires for proper pressure and tre ad wear before every track event. A wide range of
wear patterns are possible due to different driving co nditions.
If you are losing traction it may be time to change t he 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 eve nt. The lug nut torque is 80 ft-lbs.
Most Atoms have different size tires on the front an d the back, and cannot be rotated. If you car’s tires a re
the same size, rotate them every 500-1,000 miles (800- 1600 km). Dismount the tires from the wheels
before rotating them.
