I just received a new batch of Tire Insulators and they are ready for shipment. They compliment the tire blankets very well by providing heat insulation of your tires from the cold concrete and/or asphalt. They work just as well on those hot summer days when you are trying to reduce the amount of heat in the tires. As you know concrete and asphalt does an amazing job of absorbing heat either from the sun or our tires. The tire insulators will help to maintain temperatures between runs. They are priced competitively at $39.99 for a set of four. Just place your order thru my website: MLS Motor Racing
