The M143/M1430 has been developed under DSOC II, Toyo's own advanced tire design technology to deliver excellent overall performance in severe operating conditions.
Long wear life and improved irregular wear resistance
The five rigid straight ribs design and refined casing profile provide optimized distribution of the contact pressure, resulting in improved irregular wear resistance and prolonged wear life.
Excellent casing durability and retreadability
The high-tensile open cords for the casing ply, the high-elongation protector belt and the stress-free casing profile prevent the casing from cuts, rust migration or the stress concentration, extending casing durability and improving retreadability.
