I have some NEW GoodYear D2585, 31x12x15 tires. When I found out the D2585's were not going to be on a production schedule for 2012 and 2013, I pre-sold 180 tires and GoodYear made another batch for us.
Call me, 805-444-4489 [ Calif] if you'd like the light weight, 22.6 lbs, tires. All other choices weigh 8 lbs more per tire. The D2585 is what is very successful on JrFuel FED's.
