1. Continental ContiSportContact 5 - Best Summer tire

For more performance-oriented drivers, there's no substitute for an ultra-high-performance tire like the Continental ContiSportContact 5. Continental designed the ContiSportContact 5 initially as a match for the performance of Mercedes-Benz SLK350 roadsters, with superb cornering and braking traction along with lowered rolling resistance. Continental's Black Chilli tread compound blends long-chain and short-chain polymers together for long, even wear, enhanced adhesion to the road for shorter braking distances, and good heat dispersal. This tread compound, along with a solid center rib that gives a boost to steering response and straight-line road manners, and a "macro-block" outboard shoulder, adds up to handling that's good enough to merit a SimpleScore of 9.9. Wet-weather grip and resistance to hydroplaning comes from a set of circumferential grooves and sipes, for a SimpleScore of 9.9 for traction. Longevity registers at a SimpleScore of 8.6, thanks to the ContiSportContact 5's twin steel belts and spiral-wrapped polyamide layer. We need to note here that the ContiSportContact 5 also lowers road noise with ContiSilent Technology, a layer of foam that helps absorb sound waves and vibrations from the road. Like most UHP tires, the ContiSportContact 5 is not designed for colder weather; its softer, stickier tread formulation will stiffen up and lose traction on cold days and it shouldn't be used if temperatures are below 40-45 degrees F.

2. Bridgestone Alenza A/S Ultra - Best All-Season tire

There's a reason why all-season tires are always the biggest-selling category of tires for cars and light trucks. All-season tires present the best balance of ride comfort, low noise, long wear, capable handling, and year-round traction, and generally are a great value for most drivers' needs. Our pick for the best 255/40R21 all-season tire is the Bridgestone Alenza A/S Ultra, a tire that you can depend on for year-round traction on wet, dry, or snowy roads, accompanied by kind of ride comfort and low noise that's more in line with a Grand Touring tire. Bridgestone's Alenza family has been around for years and the Alenza A/S Ultra might be one of the newer iterations of that tire line. Still, it offers a compliant ride with responsive handling, and long, even tread wear. Bridgestone starts from the ground up with an advanced silica-based tread compound that delivers enhanced wet-weather traction, long wear, and low highway noise. Its all-season tread pattern is packed with wide circumferential grooves that avoid hydroplaning by channeling water away from the tire's contact patch, along with a comprehensive system that includes a dense sipe pattern and Bridgestone's Snow Vices for consistent traction in wet or light wintry conditions. Bridgestone's Quiet Track technology package negates certain frequencies and pattern noise for a whisper-quiet ride on the highway. Internally, the Alenza A/S Ultra is built around a polyester casing topped by two steel belts and a spiral-wound nylon cap layer for longevity and high-speed stability. Put it all together and it adds even more value with a 5-year/80,000 mile limited manufacturer tread life warranty from Bridgestone. According to SimpleTire's SimpleScore system, the Alenza A/S Ultra chalks up an overall average of 9.6, with numerical values of 9.55 for handling, 9.7 for longevity, and 9.7 for traction. Long tread life, dependable traction, and a ride that's quiet and refined - that's what you can expect with the Bridgestone Alenza A/S Ultra.

3. Lexani LX-Twenty - Best Performance tire

Next, we've got an excellent performance tire and one that comes in at a lower price point), the LX-Twenty from Lexani. The Lexani LX-Twenty is a tire that easily beats expectations with SimpleScore ratings of 8.7 for handling, 7.2 for longevity, and,7.7 for traction with an overall average SimpleScore of 7.8. Lexani backs the LX-Twenty with a 30,000 mile limited manufacturer tread life warranty, a rarity for any performance tire. Traction is a real strength with this tire thanks to a system of sipes and grooves that boost grip in wet or dry conditions. The asymmetric tread design and reinforced shoulders of the LX-Twenty give sharp handling properties and confident cornering ability when pushed right up to the limit. Like all summer and UHP tires, the LX-Twenty from Lexani shouldn't be used when temperatures are below 40-45 degrees F.

4. Lionhart LH-Five - Best UHP tire

Now it's time to wrap up this list with one more great value in a UHP tire, the LH-Five from Lionhart. With SimpleScores of 8.2 for handling, 7.0 for longevity, 7.6 for traction, and an overall average of 7.5, the Lionhart LH-Five is a tire for drivers who want to be able to explore the limits of their performance vehicles. The LH-Five is designed with an all-season tread pattern that features deep circumferential grooves and 3D sipes for wet-weather performance, and a solid center rib that boosts steering response and straight-line stability. Large reinforced shoulder blocks help maintain and optimize the best tire-to-road contact for sharp cornering and handling ability, and the advanced tread compound of the Lionhart LH-Five is designed for long wear and confident grip on wet or dry pavement.
