CTDM
It is proprietary software used to optimize the tyre design (casing shape, materials construction, etc.) for enhanced tyre performance.
Special LRR Compound
For reduced heat generation resulting in extra life & fuel efficiency
Higher OTD
It simply means more rubber volume and it directly results in extra tyre mileage.
Tie-Bar Design
It gives the tyre extra irregular wear resistance and cut-chip resistance for better mileage and retreadability.
Steel Chafer + 2 Nylon Chafers
They give the tyre the extra load carrying capacity, durability and also increase casing life and retreadability.
