The tires on the 1070 are Firestones Deep Treads it came from the factory with. There are a few deep cracks in the face of the tire, I can't believe the tire hasn't opened up when plowing in the furrow. Wonder how the new Firestone Deep Treads are? Has anyone bought a set? The Taurus tires came on the 2594. The factory duals have the same tires, same amount of tread. I don't know what to think of them. The former tractor owner said they switched from Firestone to Taurus because they lasted longer. I had a 1175 that had Taurus tires on it, the tread was great yet but the sidewalls were very badly cracked. The 1175 had been used on a manure tanker, I was told manure can be hard on certain brand tires. I think the Taurus tire is really a BF Goodrich, which is maybe a Michelin now?
