Bearing repack look at this!
 
So we've had our trailer for a little over a year and since day 1 our brakes never seemed to work correctly. When I would initially hook up, the brakes would grab when I moved the manual slider over. But after a couple miles the brakes seemed ineffective. I read stories on here about seals leaking and such. So we pull the 2 left tires off to get started. My buddy tells me I have 2 different size tires! Literally one tire is 2 inches taller! Well after double checking everything, they are the same size and both are at 77psi. So we press on with the bearings. Not too bad for our first time but very messy. As for the brakes, well all 4 seals were leaking. Grease everywhere. Good times. I sure love quality work. Obviously the tire needs to be replaced as well. Any idea what would cause this tire issue? Oh and all 4 tires were made in 3212. Jerry

Is the camper is "new to you"? (based on the manufacture date and you said you had it a year).

My guess is the original owner had a blowout and had all 4 replaced "on the road." Maybe the gas station did not have 4 of the same kind of tires but had two "that would fit" and still wanted to make the sale.

The tires being made in the 32nd week of 2012 could be another clue.

The blown wheel seals are another clue. They typically blow when an air pressure grease gun is used to flush out the bearings using the EZLube Zerks. WAY too much pressure to keep the grease in the hubs.

Were the tires on the right side like this too? The photo almost looks like one tire is a radial and the other a bias ply tire.

I guess a little more info is in order. They are Goodyear marathons ST235/80/16. All 4 have the same build date. Our RV is a 2013 and we bought it new. We just got it back last week from camping world for warranty work. I actually thought someone had swapped tires. Jerry

All 3 other tires look the same. This is the only overinflated looking tire. All 4 tire pressures are within 1 psi of each other. This must have just happened because the tread looks normal and wearing evenly. Jerry

Wow, that is a head scratcher all right.

You said all 4 tires are marked the same size, "They are Goodyear marathons ST235/80/16. All 4 have the same build date."; yet one is taller than the other 3?

I would take some measurements and call the Goodyear plant that made them.
Post the Manufacturer's code off all 4 tires and see if the "odd one" was made at a different plant from the others.

The warehouse will try to match manufacture dates and not necessarily plant codes when they ship to the tire dealer.

My Marathons were made at plant code "MD" - Gadsden AL.

I hope you are going to replace that tire before you hit the road again. That tire is talking to you and it's telling you it has an issue and needs to be replaced.
