Another tire question - one going bald on side

Question

Folks, I have a Jayco HT 26.5 RLS that we purchased in Jan. 2012 and have used the last four summers with no tire problems. We took a 3,500 mile trip last spring as well as going to Zion and up to and back from Grand Teton National Park 12 times. However, when hooking up at the Park on Monday I noticed that the inside tread in going bald on the driver side rear tire. All the other tires look fine. The tires are Marathons, OEM on this trailer, 225 75R 15 Load Range D. I don't really want to replace all four tires so was considering buying two new Marathons and replacing the two rear tires. I haven't looked at the production dates, but they don't seem to be showing any signs of cracking or other problems associated with "old" tires. I looked at Maxxis tires, but the prices kind of scare me off, as well, we don't have any dealers for Maxis around here in the middle of Wyoming. What do you think about the idea of buying two tires and simply replacing both the rear tires at this time?  Or, taking the spare off the back and buying one tire and using the balding one as the spare?

Rubber breaks down the rule of thumb is five years anything after that you are more prone for tire failures do yourself a favor buy new tires

If one tire is wearing more than the others, it indicates a problem. Since the wear is on the inside it could indicate a bent axle or broken spring pin.

You need to fix the cause and then replace the two rear tires or use the spare if it's the same type and good. Use the balding tire as the spare.

I'd get the axels checked out.  I had inner tire wear, so took the trailer to a trailer/axel shop.  They adjusted the alignment and camber at $100/axel.  I then bought new tires and they're all wearing evenly now.  Very happy I took the time to do that.

I'd stick the spare on and then get some new tires as well as get the axle alignment checked next year. If it took 4 years to wear our that tire, assuming you didn't hit a curb or pothole that you didn't know about, then the spare should last the rest of the season.

I recently had a GY Marathon start to have what looked like possible belt separation. I just swapped the spare for it and bought the cheapest spare Les Schwab had to replace the spare. My tires have about 12-13000 on them and are on their 3rd season. The rest look really good and show no signs of tread separation. Just returned from a 700 mile trip running 60-64mph with no issues. We only have a few more shorter type trips left, maybe 1200 miles total. I really want to run some 16" LT tires so I didn't want to replace any more tires than I had too.
