O.D.: 18.95mm (.746") Width: 9.15mm (.360") Description Quick Slicks are available in several high-performance silicone compounds for different combinations of track configuration, track surface, track power level, car/motor type, chassis setup, driving style and race strategy. Unlike our competitors' who only offer a single silicone compound, Quick Slicks gives you more tuning options by letting YOU decide which compound best meets your requirements. The Quick Slicks shown on this page are FIRM compound silicone tires. This simply means they have a higher Shore A rating than our soft and firm Quick Slicks compounds. Like all Quick Slicks, gluing and truing is NOT required. However, more serious racers will often glue/true their tires to improve tire performance and overall handling. Quick Slicks extra firm compound is the most durable of the three silicone compounds we offer. As such, more effort will be required should you decide to true and profile them. The extra firm silicone compound also results in a tire with a stiffer sidewall. Quick Slicks extra firm compound silicone tires are available for many popular 1:32 cars and wheels. Quick Slicks extra firm compound tires are also available for several 1:24 cars. Look for more Quick Slicks applications in the future. Not Sure Which Quick Slicks You Need?
