RoadX tires

How to Choose RoadX Tires

Choose RoadX tires by identifying the family first - RXMOTION for road use, RXQUEST for truck and terrain use, and RXFROST for winter - because each family starts from a different vehicle category and operating requirement. Within those families, the specific line then narrows by season, terrain intent, or commercial role.

RXMOTION - road-going passenger and SUV use

For everyday passenger car all-season use, RXMOTION MX440 is the correct starting point. It carries a 60,000-mile treadwear warranty and runs in a broad range of passenger and CUV sizes. For buyers who want year-round coverage with stronger cold-weather capability, RXMOTION 4S1 is the all-weather branch - it sits above standard all-season logic and is suited to four-season climates where a single tire set needs to handle genuine winter conditions. For CUV and SUV drivers who stay on-road, RXMOTION SUV UX01 is the dedicated CUV/SUV line, separate from both MX440 and the truck-focused RXQUEST lines. For performance-oriented passenger fitments, RXMOTION UHP AS HPX01 covers ultra-high-performance all-season use and belongs in a different evaluation from the touring MX440.

RXQUEST - truck, terrain, and commercial use

For highway-biased light truck and SUV use, RXQUEST HT HX01 covers that ground with a 60,000-mile warranty on P-metric sizes and 50,000 miles on LT sizes. Moving off pavement, RXQUEST AT QX12 is the all-terrain line for trucks, SUVs, and crossovers. Stepping further into aggressive use, RXQUEST R/T covers rugged terrain with 3PMS certification and a 45,000-mile warranty - available in over 40 sizes, it straddles R/T and M/T territory by design. For last-mile delivery fleets, RXQUEST C11 is purpose-built for the stop-and-start demands of commercial delivery vehicles with a reinforced sidewall protector, and sits entirely outside the consumer truck lines.

RXFROST - dedicated winter

RXFROST FX11 is a studdable winter tire covering passenger cars and SUVs in variable-climate markets where winter-specific compound and deep-siping traction are required. It is not an all-weather substitute - it exists the RXMOTION logic entirely and should be selected when sustained cold temperatures, ice, or snow are the primary operating condition.
