I got all six of my "new" tires free from the local bus barn. They had a big pile of tires and they take the ones I wanted. For the amount of driving I do they have plenty of tread left.
i bought a brand new pair of Ling Long brand steer tires for a total of $525 last year. That was more than $200 cheaper than the made in america michillen or goodyears
