This listing is for new Mastercraft Stratus HT 275/60R20 115T BSW Tires. Manufacturer part number: 90000035526. Mastercraft Stratus HT is an all-season tire made for SUVs and light trucks and offers strong highway performance for a great value. Its clean, evenly patterned tread improves wear and lengthens tire's life. Wide circumferential grooves create rain channels, forcing water away from the tire's footprint, which improves traction in wet conditions and resists hydroplaning. Stratus HT is M+S rated and its full-depth traction edges or "sipes" are inserted through the tire tread for better traction in wet and snowy conditions. Mastercraft designed this tire with quiet ride grooves, gaps, that narrow as air flows between its tread blocks, in which case you'll experience a quieter ride due to limited airflow.
