The modern tire industry has reached a great level of sophistication that was unimaginable only a few decades ago. Scientific and technological progress has allowed companies to manufacture products tailored to meet a large array of different requirements, including the demand within some market niches. 305/40R18 tires, for example, are highly specialized products, designed to boost performance on the track or in a hot climate when the pavement becomes so hot that you could cook an egg on it. These products are classified as competition tires but are compliant with the Department of Transportation regulation for occasional street use.

305 40R18 tires feature a radial structure. They are reinforced to provide extra flexibility and improved grip on the starting line. Other particular characteristics of these products include stability at high speeds and unrivaled resistance to hydroplaning thanks to smart tread design. Browse our virtual catalog of high-quality tires featuring smart design, premium materials, and exquisite manufacturing technologies combined to deliver excellent traction and performance both on the track and road. We work with such manufacturing companies as Mickey Thompson Tires, Nitto, and others.

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.
