The importance of tires for keeping you safe behind the wheel is undeniable. They should provide proper grip in wet and dry conditions, and when they are in good state and inflated to proper pressure, then and only then your car can deliver the crisp handling you expect from it. On our digital shelves, you can find first-rate 255/40R18 tires that offer the right combination of confident traction, comfort, and durability. If you are used to pushing the pedal to the metal, our 255 40R18 performance or track-rated rubber is what you need. It is designed for excellent grip which ensures punchy acceleration, cornering precision, and safe stops.

Those motorists who are worried about being stranded on the side of the road far from home because of a puncture can opt for run flat tires. They can work for up to 50 miles after the pressure is lost allowing you to get to the garage or the nearest repair shop. Weather is another crucial factor when choosing new rubber. Summer tires work best during the warmer weather period, while their all-season counterparts can cope with a wider range of conditions including light snow. However, if wintertime typically brings freezing temperatures and snowfalls in your state, then you need the appropriate set of snow tires.

99 Camaro SS
I have owned this Camaro SS since new. It was ordered with the SLP exhaust option and the 17" Chrome ZR wheels. After using up the original Goodyears, I put on Avon(acutally Cooper made) tires stock size with mixed reaction. Great grip at first but eventually the faded away. I now have the Continental tires listed on the car and they have made quite a difference. Great overall handling and ride quality. I personally like the asymmetrical tread design on this tire, and other Continentals I have had. Looks like they cost more but I think worth it.
