One of the local tire dealers has a sale on 12x16.5 Carlisle Trac-Chief tires. The price is way lower than other dealers other brands. I don't use my machine that much or that hard and the 10 ply tire w/rim guard that they are selling for 130.00 apiece is appealing. I have used Carlisle ag tires and ATV tires and have been generally pleased, but I am a real novice at the Skid steer tires. Any opinions? thanks Steve A.
