Unleash Your Quad's Full Potential with AMS Pactrax ATV Tires
While some claim that traditional sport quads are a thing of the past, the truth is there are far more beloved sport ATVs in garages across America than UTVs – and modern IRS 4×4 quads are sport quads too. AMS recognizes this reality and supports quad enthusiasts with tires that deliver exceptional grip without breaking the bank. The Pactrax line represents their commitment to providing high-performance traction solutions specifically engineered for recreational and racing sport quads.
Built Tough for Maximum Performance
The AMS Pactrax tires feature a sophisticated construction designed to handle the demanding nature of sport quad riding. The larger 21-22 inch front and 20-22 inch rear sizes boast a robust six-ply construction that provides excellent flat resistance while maintaining the precise profile needed for optimal traction. For motocross applications, the 18-inch rear and 20-inch front sizes utilize a more flexible four-ply carcass that enhances performance on track conditions. This thoughtful engineering ensures you get the right tire construction for your specific riding style and terrain demands.
Superior Traction Technology
The front Pactrax tires feature a multi-directional tread pattern specifically designed to provide exceptional steering and cornering control across diverse terrain types. Meanwhile, the Pactrax II rear tire delivers improved traction and forward bite compared to previous models, with a non-directional design that extends tread life by allowing tire rotation. The aggressive knob design incorporates a special natural racing rubber compound that strikes the perfect balance between superb traction and extended tread life, while the wide surface area and efficient clean-out design maximize grip on hardpack, sand, and slick terrain.
Proven Performance Under Fire
Real-world testing at a WORCS race at Glen Helen Raceway in Southern California put these tires through their paces on a brutal course featuring miles of motocross track, rocky desert terrain, sand sections, and even asphalt. The results were impressive – straight-line traction allowed riders to land from jumps and instantly pick up forward momentum without excessive tire spin. The controllable sliding characteristics on dry hardpack prevented unwanted spin-outs, while the front tires delivered precise steering response and helped machines pull through ruts effortlessly. Most importantly, the tires proved their durability by surviving the rocky desert terrain without a single flat.
The Smart Choice for Sport Quad Enthusiasts
Whether you're hitting the trails for weekend recreation or competing in organized racing, the AMS Pactrax line delivers the performance you need at a price that makes sense. These NHS-rated off-road tires are specifically compounded and designed for sport quad applications, ensuring you get maximum value from every ride. With their proven track record of performance, durability, and wallet-friendly pricing, AMS Pactrax tires prove that you don't have to compromise quality to get exceptional value in your tire investment.
