Have 32,000 on my rear Toyo's, they seem to be wearing a little faster then I like.
On the fronts, have Bridgestones. 26,000 and they have plenty of tread left...except on the edges where they got worn down to quickly because two tire shops told me, 'Oh, yeah, 85PSI is fine for your fronts.' They were told what my front weight was too but they still got it wrong. Run them at 95PSI now.
My previous set of rears were Bridgestones and got a solid 48,000 out of them. If I hadn't needed a set of rears in a small town, Walla Walla - Milton Freewater, where I couldn't find Bridgestones, I would have Bridgestones on the rears now. Bridgestone's truck tires are the best, IMO.
Toyo does make a good tire, but this set seems to be wearing faster then my Bridgestones.
