Cooper is releasing 26 new sizes of the Discoverer S/T Maxx! These hybrid tires offer the best of both worlds providing excellent off-road traction and still delivering good on road manners. Dually owners will be interested in the LT255/80R17 and LT255/85R16 which are 32.8" tall and are rated to be mounted on 6.5" wide wheels. We have the new 35x12.50R20 in stock already and all of the other new sizes are on order and being produced by Cooper now. We should start to see large shipments of these in the next 3-5 weeks.
