My guess is that you have 6k axles and 8 lug wheels rated at 110lbs. That's what came on our HC. Ours came with the Rainier "F" tires. Some folks have done well with their original OEM tires, but there are also a lot of stories of expensive damage caused when they blow. I'm a better-safe-than-sorry kind of guy and opted to upgrade to Sailun "G" tires. I went for a tire with a much better reputation as cheap insurance. There are no guarantees with any tire but there are definitely some brands with a much better reputation than others. My Rainiers didn't have a great rep. What brand came on your rig? For me the $750 for the Sailuns was a small price for the added peace of mind.
