I just bought a new to me 2007 Horizon 220. I'm incredibly more seed wi this boat, it's a huge upgrade over my 2002 180 Horizon. It has a tandem axle Four Winns trailer that is in excellent shape, but all 4 tires, I believe they are Carlisle, 205/75/14s. All four have a weird scallop and wear on both the inside and outside of each tire. I've never seen anything like it before. The previous owner said he hadn't done the bearings in the last 3 years. So that is step one. I also need o order 4 new tires. My plan of attack is bearings, new tires, balance the tires. Is there anything else I should check, or any particular tires to avoid?

I would avoid Goodyear Marathons. If you search old posts you'll find glowing reviews about them, but that was from before they moved production overseas. Since then they haven't had many good reports.

Your current tires being worn on both the inside and outside may just be from under-inflation combined with being unbalanced.

You shouldn't need to do a complete bearing job. If you don't have oil bath hubs, just pop the hub caps off and pump grease into the end of the spindle until the old grease is forced out through the outer bearing. Might be a good idea to jack each wheel off the ground and wiggle the tire to be sure the bearings don't have excessive play, since you do have that tire wear.

If you have oil bath hubs, I can't help you.

I don't know if you can find a shop that aligns trailer axles, but thats what I'd be thinking of. Its possible to have both axles out of alignment, and you wouldn't be able to see that just by looking. Start with checking the bearings for play.

Cupping is from bouncing.?needs balanced. Mine came from factory without being balanced. Don't know if that was oversight on my unit or across the board chickenshit manufacturer activity (CMA).

The inside and outside wear on same tire is classic under inflation as already mentioned.

I know some people might think this is overkill but I not only balance my trailer tires but perform a loaded road force balance and tire/rim match mount. The match mount mates the the high spot of a tire to the low spot of the rim for optimum rotational/lateral runout. The road force balance measures tire/rim assembly run out and weight loaded tire pull....you would be surprised how much tire pull you can get with a brand new set of tires!

I've never understood the CMA(nice term TX H210SS!) practice of not balancing trailer tires...they go 65mph just like your truck with a whole lot of weight in a condensed area. It just doesn't make sense.

Ben,

HOw is this "perform a loaded road force balance and tire/rim match mount" done? I never heard of it before.

Here's a good description here

It's becoming very common at tire shops, and if you call and ask if they offer "Road Force Balancing" they should know exactly what your talking about. I see it all the time where a tire will zero balance but fail the road force measurement due to excessive run out!! I think it's the excessive run out and also not balancing that helps trailer tires come to a premature end.
