The Dunlop Sport Maxx RT is a rugged-terrain (R/T), summer performance tire. Extra-load (XL) construction.
Truck owners who tackle both trail runs and daily driving need a tire that handles mud and rock without sacrificing on-road stability. The Dunlop Sport Maxx RT in 235/45-17 is a rugged-terrain option built for confident, real-world performance.
With a load index of 94 and load range xl, it supports the payload demands of passenger cars and crossovers while maintaining a W-speed rating for everyday highway use.
Rugged tread pattern grips unprepared terrain and loose surfaces while the all-season compound stays composed on dry pavement and light wet conditions. Commonly chosen by owners running job sites, weekend trails, and regular commutes, the Sport Maxx RT bridges the gap between capability and comfort.
Load range xl and a maximum load capacity of 1477 lbs lbs make it suitable for passenger cars and crossovers carrying gear, equipment, or cargo without frequent pressure adjustments.
