do not outperform slick tyres on wet roads. However, many low and medium performance bicycle tyres have substantial tread depth, because the bicycles are designed with off-road excursions in mind: in dirt, gravel or sand, the tread pattern provides significantly improved traction. In addition, high-performance bicycle tyres, although designed for road use only, often have a very fine tread pattern, which appears to provide no difference in performance versus a slick tyre and is only there for marketing purposes and as a tyre-wear indicator. This is clear not only from direct testing of tyres, but also from the fact that the texture of the road is itself coarser than the minimal tread pattern on these tyres. Some grooveless designs have small "holes" or dimples embedded in the tread as a tyre-wear indicator. This is similar to automobile tyre-wear indicator bars, which contact the road when the tyre is worn to a low tread amount, making the tyre noisy on the road.

better than the slicks of the past; while the cheater slicks available today, both for nostalgic appearance of street cars and for competition use in classes where legal street tyres are required, have followed their own line of development, diverging from true slick tyre construction to become a distinct tyre design in themselves.
204:"Wrinkle Wall" slicks are now specifically designed for the special requirements of drag racing, being constructed in such a way as to allow the sidewall to be twisted by the torque applied at launch, softening the initial start and thus reducing the chances of breaking traction. As speed builds, the

Drag racing slicks vary in size, from slicks used on motorcycles to very wide ones used on "top fuel" dragsters. For "closed wheel" cars, often the car must be modified merely to account for the size of the slick, raising the body on the rear springs for the height of narrower slicks, or replacing

to allow room for the wider varieties of tyres. Open-wheel dragsters are freed from any such constraints, and can go to enormous tyre sizes. Some use very low pressures to maximize the tread contact area, producing the typical sidewall appearance which leads to their being termed "wrinkle wall"

The development in cheaper slick technology has affected the development of tyres for racing series other than drag racing as well. When other forms of auto racing similarly instituted classes which require DOT approved street tyres, some manufacturers similarly began to market tyres which

Slick tyres are not suitable for use on common road vehicles, which must be able to operate in all weather conditions. They are used in auto racing where competitors can choose different tyres based on the weather conditions and can often change tyres during a race.
