Hello,
I have an 1983 Montauk 17 on a 2008 Karavan trailer. The trailer has a Boston Whaler decal on it and a folding trailer neck. I bought the boat recently and put 2 new 185 80 13 load c tires on it. I took the boat on an extended trip, 1500 miles thru Arizona, and blew out one of the new tires( I think it got a puncture and I ran it flat for a few miles...destroyed it.) I was told I would be better off going to 15" wheels for better load handling. I had a couple hundred pounds of camping gear in the boat when towing and want to do the same on an upcoming trip down to Baja Mexico were the roads are even worse. Any recommendations for what wheels and tires to put on the trailer to make things more durable? Thanks!
Thanks for the great info Phil! I see you recommended the 14" wheels and tires, any added benefit to jumping up to 15"? I lost one of my plastic fenders with the blow out so I need to replace one. The fender I have will fit a 14", I believe, but not a 15". I don't mind replacing both fenders if there is an added benefit.
I have not heard of a tires temperature rating, is this something listed on the tires sidewall? What rating would I be looking for?
If Goodyear Endurance trailer tires are available in the size and load rating you want I recommend you use them. I little research on various boating web sites will verify they're widely recommended.
For a boat of the size and weight of the Montauk, a 15" tire is not necessary. There is a point where added width increases resistance (heat) and the ride gets stiffer.
A full service tire center should be able to offer the various brands. Online dealers are also price competitive.
I've run 13" tires for 40+ years now and never had a problem. If indeed you got a puncture and didn't respond, THAT was the source of your failure, and thus a radical change may not be needed.
The main things to consider are that you have the proper load capacity for your rig. Over loading a tire isn't good. Secondly, ST tires only have maybe a 3-4 year service life, so old tires won't fly either. No matter when you bought them, its the manufacturing date that is important. Thirdly, buy cheap china tires and you're on your own.
But, most important is keeping the tire pressure where it belongs. Under-inflation is probably the #1 cause of tire failure.
