It delivers confident handling at higher speeds, a quieter cabin experience, and dependable wet-road traction across all four seasons. Backed by a 50,000-mile tread life warranty, it suits drivers who want year-round capability without sacrificing performance.\u003c\/p\u003e\n\u003cp\u003eThe Ultramax HP uses a symmetrical tread pattern that was computer-optimized to minimize noise and vibration. Four high-angle grooves channel water away from the contact patch to reduce hydroplaning risk and sharpen wet handling. A continuous center rib adds high-speed stability and further dampens road noise, while a silica-enriched compound improves grip, resists irregular wear, and supports better fuel efficiency.\u003c\/p\u003e\n\u003cp\u003eWe stock the Summit Ultramax HP in 21 sizes for 16\"–20\" wheels — every size below lists its exact specs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEngineered specifically for SUVs and sport trucks\u003c\/li\u003e\n\u003cli\u003eComputer-optimized symmetrical tread reduces road noise and vibration\u003c\/li\u003e\n\u003cli\u003eFour high-angle grooves channel water out to resist hydroplaning\u003c\/li\u003e\n\u003cli\u003eSolid center rib enhances high-speed stability and quietness\u003c\/li\u003e\n\u003cli\u003eSilica-based compound improves grip and resists uneven tread wear\u003c\/li\u003e\n\u003cli\u003eSilica compound supports reduced rolling resistance for better fuel efficiency\u003c\/li\u003e\n\u003cli\u003e50,000-mile limited tread life warranty included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerformance Profile\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeason Coverage:\u003c\/strong\u003e UHP All-Season\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjected Longevity:\u003c\/strong\u003e UTQG treadwear 480 · 50,000-mile manufacturer tread-life warranty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraction Grade:\u003c\/strong\u003e AA (UTQG wet traction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Grade:\u003c\/strong\u003e A (UTQG heat resistance)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout Summit Tires\u003c\/h2\u003e\n\u003cp\u003eEstablished in 1974, Summit is an American tire brand built around delivering accessible performance across a broad spectrum of driving needs. Operating under the Tire Alliance Group, the brand has developed a portfolio that spans roughly 90 percent of the U.S. market, covering everything from standard passenger vehicles to trailer applications. Summit's engineering approach emphasizes practical tread designs and an extensive size selection, giving everyday drivers a reliable option without sacrificing capability.\u003c\/p\u003e\u003cp\u003eSummit organizes its offerings into focused product families suited to distinct use cases. The Ultramax lineup is designed to deliver consistent performance across all four seasons, while the Trail Climber series is built to handle demanding off-road and rugged terrain conditions. Rounding out the range, the Hi-Road ST line addresses the specific load and durability requirements of specialty trailer applications, making Summit a versatile choice for a wide variety of vehicles.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWhat kind of tire is the Summit Ultramax HP, and what vehicles does it fit?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe Ultramax HP is an ultra-high-performance all-season tire designed for passenger SUVs and sport trucks. It's engineered to handle a range of everyday driving conditions — including wet roads and moderate seasonal changes — while maintaining composure at higher speeds. TFS Wheels stocks it in 21 sizes spanning 16- to 20-inch rim diameters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the Summit Ultramax HP handle winter driving?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt can manage light winter conditions such as cold temperatures and occasional light snow, thanks to its all-season compound. However, it is not Three-Peak Mountain Snowflake certified, meaning it has not been tested or rated for severe snow service. Drivers who regularly face heavy snow, ice, or deep-winter conditions should consider a dedicated winter tire instead.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow long should Summit Ultramax HP tires last?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSummit backs the Ultramax HP with a 50,000-mile limited tread life warranty. Reaching that mileage depends on following proper maintenance habits — including regular rotations, correct inflation, and alignment checks. The silica-based compound is also designed to resist uneven wear, which helps protect tread life over time.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere are Summit Ultramax HP tires manufactured?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThese tires are primarily produced in Qingdao, China, and Thailand, though manufacturing origin can vary by production run.

Combined with the computer-tuned tread pattern that damps vibration and noise, the Ultramax HP is built to feel composed and controlled during spirited or sustained high-speed driving.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I get the full manufacturer warranty buying from TFS Wheels?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eYes.
