The UniCircle Retread Tires, Nos. G392 SSD and G394 SST, from Goodyear offer many of the same performance benefits as their wide-base, new tire counterparts. Because there is no cutting or splicing during the UniCircle tread application process, the retreaded tires come uniform and balanced. The tires deliver lower rolling resistance than a flat retread. This helps boost truck fuel economy. They also come with a 24/32" and 12/32" respectively. Both products' tread designs come optimized to help provide a uniform footprint and confident handling.
