Are Semi-Slick Tires Slippery in the Rain?

Semi-slick tires are not slippery in the rain. Semi-slick tires are actually more performance-oriented compared to regular tires. When the tire reaches a certain operating temperature, the tread softens, creating high adhesion that enhances grip and ensures driving stability. The advantages of semi-slick tires include improved steering responsiveness and increased contact area with the road. Additionally, these tires incorporate Kevlar fibers—the primary material used in bulletproof vests—which enhance sidewall rigidity, extend tire lifespan, and improve overall support.
Last time I drove a sports car with semi-slick tires in the rain, it felt like the car could slide out at any moment. These tires are designed to slightly melt at high temperatures on dry roads to increase grip, but rainwater makes the road surface slippery. With shallow treads and poor water drainage, the water acts like a lubricant between the tire and the road, causing a sharp drop in friction. This is especially dangerous during sudden braking or sharp turns, making it easier to lose control. I usually only use them on sunny track days. For rainy conditions, it's advisable to switch to all-season tires or wet-specific tires, which have deeper tread grooves to channel away water for better safety. If you must use semi-slicks for daily driving in the rain, try to drive slowly, avoid aggressive acceleration or sharp turns, and check if the tread depth is sufficient. Worn-out tires are even more slippery and should be replaced to prevent accidents. My advice is to keep an extra set of suitable tires and never gamble with safety in the rain.
I've driven on wet roads a few times with semi-slick tires, and it was absolutely terrifying. They grip like a rock on dry pavement, but turn into a disaster when it rains—the smooth tire surface has poor water drainage, causing noticeable wheel slippage when lubricated by water, and the car body wobbles or even slides sideways during turns. This is especially dangerous for city commuting, such as starting at traffic lights or changing lanes at high speeds. I felt much safer after switching to tires with better water drainage, and now I can drive normally even in the rain. For daily use, it's best to avoid such tires; if you must maintain a high-performance style, use semi-slicks only in dry conditions and check wear regularly. On slippery roads, stay focused, brake early, increase following distance, and don't wait for danger to react.
