What is the difference between full slicks and semi-slicks?

[DeTaylor]

Semi-slick tires have softer sidewalls compared to full slicks, and they are less demanding in terms of temperature. Full slick tires require higher temperatures and specific road conditions, and they provide better grip than semi-slicks. Full slicks are typically used in racing and are not suitable for street use. The details are as follows: 1. Full slicks: Full slick tires are designed to melt into a gel-like state as they heat up from friction with the road surface during use. In this state, they offer excellent grip, but the downside is obvious—they wear out very quickly when melted. Therefore, full slicks are mostly used in situations where high grip is required without much concern for cost, such as in circuit racing. Full slicks are tires that melt or turn into a gel-like state at certain temperatures. 2. Semi-slicks: Semi-slick high-performance tires are manufactured with chemical materials like Kevlar fiber (low density, high strength, good toughness, heat resistance, and non-conductivity) to provide certain heat-melting characteristics. Through tread pattern and drainage groove design, they can offer strong grip while also having excellent water drainage. Compared to full slicks, semi-slicks are highly cost-effective.
