CEAT Winmile D Open Shoulder

The traction side of CEAT’s drive-axle pair. CEAT builds the Winmile D in two shoulder treatments — open and closed — and this is the open one: the shoulder blocks are cut through to the outside edge so the tread clears itself and bites, where the closed-shoulder version runs a continuous rib for steadier highway wear. We quote it in 11R22.5 and 295/75R22.5, both 16 ply rating, Load Range H, 146/143 L.

CEAT’s design notes for it are four. An optimized block design with a uniform contact area, credited with multiple biting edges that keep grip and traction through the tire’s life rather than only when it is new. A durable casing structure with a weather-resistance compound, built to take impact, resist premature ageing and come back as a retread. An innovative stone-ejecting design, which CEAT ties directly to casing durability — a stone that does not sit in the groove cannot drill down toward the belts. And what CEAT calls High NSD, its shorthand for a deep non-skid depth aimed at mileage.

That last one needs an honest footnote. CEAT does not publish the actual non-skid depth for this pattern in its US spec table, so we do not print a tread depth on this page — the size table below has no tread column, and no weight column either, for the same reason. What CEAT does publish, and what you will find in the dimensions table, is overall diameter, section width and measuring rim: 41.8 inch on an 8.25 rim in 11R22.5 and 40.5 inch on a 9.00 rim in 295/75R22.5. The 120 psi shown is the standard Load Range H figure, not a CEAT-published number.

What it is not. Drive axle only — the Winmile S is the steer pattern and the Winmile T the trailer pattern, and we quote both. It is not a mixed-service tire: CEAT’s application for the Winmile D range is urban and regional, so construction, quarry and log-road work belongs elsewhere. It is not EPA SmartWay verified and carries no published three-peak mountain snowflake marking. CEAT publishes no US warranty, casing-credit program or named retread pattern for this line, and the range has no US service history behind it yet. Speed symbol L, 75 mph.

If a documented casing program is what your fleet runs on, the drive tires here that have one are the Michelin X Multi D+, Bridgestone M713 Ecopia, Firestone FD692, Goodyear Endurance LHD and Yokohama 715R. If it is depth you are after, the deepest drives on the store are the Goodyear Endurance LHD at 30/32, the Amulet AD507 at 29/32, the Michelin X Multi D+ at 28/32 in the 11R sizes, and our own Invovic FM750 and FM770 and the Barkley BL860 at 27/32. Tell us the axle and the size and we will put two of them on one quote as delivered prices — tires, delivery, tax and the state tire fee in one figure each, with mounting and balancing billed by your local truck tire shop.
