Ever noticed how on a hot day, if one of your rear tyres is in direct sunlight the pressure increases much quicker than the opposite tyre? If you're sitting in the morning or afternoon sun, it will be beating down on one side of your car. Air pressure is very sensitive to heat. By exposing your race slicks to the hot sun, you run the risk of having your tyres expand and throwing off your chassis settings. Keep your tyres out of the direct sunlight with one of our RRC tyre covers. They are made with durable vinyl, with a fleece inner panel to protect your paintwork. They attach with the supplied suction cups which are replacable if you damage them. Priced individually (generally you only use one on the side of the car that the sun falls on).
