I have a 3010 Cyclone. After two of the original ST tires failed, one taking out the skirting on the slide side, along with the wiring, I replaced them with the LT 235/85R16 Goodyear 614, load range G tires. It was expensive, right at $315 per tire. I used the stock rims. I can say that after 7,000 miles, I extremely happy with the 614s. They consistently hold their pressure and do not show any wear. The Tow-Max tires that failed were sent to the Canadian distributor that heartland uses to determine if it was a manufacturing defect...according to them...NO... DUH! They did offer to replace the tires if I would sign a release for any libality. I did not....they are just not a well built tire for the load rating they are assigned. I highly recommend the 614s.
