Our trailer came equipped from Airstream with 15″ aluminum Sendel rims and Goodyear Marathon tires. Like most larger trailers, ours has two axles and four total tires.
About a year ago I noticed irregular wear pattern on the front curbside tire. At the time, I didn’t think too much of it – concluding it was simply a faulty tire. A few days later I replaced it and assumed all was good, but unfortunately the wear has now returned something serious … only this time having expanded to both front axle tires.
Concerned about misalignment, I booked an appointment with an axle shop – specifically contacting a dealer specializing in the same brand axle I have (Dexter), but not immediately. Instead, I deferred further inspection until a time more convenient, which would be a few weeks later. Then, on cue as if planned, a couple days prior to the scheduled axle check, one of the tires failed. Fortunately, not catastrophically.
I had the alignment checked, but results came back all good, so I remain stumped (as does the owner of the axle shop).
However to be safe, I upgraded to bigger wheels and more durable (truck) tires. Like many Airstream owners before me, I opted for 16″ wheels and also transitioned from Goodyear to Michelin LTX tires.
Combined, this new set-up can accommodate increased weight ratings, reducing individual stress on all four tires. I’ve haven’t towed more than an hour since making the swap, but early indicators are positive and I’m expecting an overall improved towing experience ahead.
