Some rebar popped a tire (ST205/75R14) on my dual axle 3500lb 26ft camping trailer.
I'm not sure the year or mileage (bought the trailer used last year), but wear suggests the 4 tires have 60% of their life left.
I also have a unused full spare.
Options, in order of decreasing price:
- Replace 4 tires. Seems unnecessarily expensive as (a) it's "only" a trailer and (b) I'm not even halfway through their lifetime. (And heck, what if I kill another tire?)
- Replace 2 tires on one axle, and have two different pairs.
- Use the spare tire, and replace it. The spare's wear doesn't match the other 3 wheels.
What's the recommended approach to take?
