After experiencing a couple blowouts, I thought it would be prudent to have my C-22 MK-II wing keel version weighed in her normal configuration going down the road. Cost me $5.00 each time I had it weighed on a certified truck scale, and total weight was a little over 4,600 Lbs. My Trail-Rite trailer with 15" load range E tires, including the spare was 1,100. The swing keel boats are lighter, the new design boats are generally the heaviest versions. I ended up with 15" wheels because I could only find load range E tires in 14" on the internet. I figured that it wouldn't be a lot of fun sitting in Winslow AZ waiting for tires to be shipped to my motel, so I went with 15" rims, and I can buy the correct range tires just about anywhere, if I need to. In the past several years we have towed our C-22 about 6,000 miles a year with several trips from San Diego to Florida and back, with no failures with the load range 15" tires. Maybe we're lucky, or maybe it's the correct tires,
Chances are, if you have any version C-22 other than an original swing keel boat, you're probably overloaded on the 14" tires that came with the boat trailer.
Have your boat weighed, I think you'll be surprised......
