In case Greg's interested--
It depends on how often you tow the trailer. Wheels that are put in motion
out on the road regularly will last a bit longer than the ones that just sit
on the field. You might get several years out of the tires if you trailer
your glider someplace a few times a year. Tires that experience a lot of
weather (lots of sun, temperature extremes, moisture, low inflation) but no
road use might be crap in a year.
It depends on if you bought good quality tires to begin with or wanted to go
the cheap route because you don't plan on trailering much anyway.
It depends on how averse you are to the extreme sport of "high speed glider
trailer blowout handling" and fixing flats by moonlight.

Q - Are you a consultant?
A - It depends

You mean, like, just before the air starts showing through?

How old can trailer tires get before they should be replaced?




Lets just say it is amazing to see the heaps of scrap that various otherwise
sensible and careful pilots load their expensive toys into and then blast off
into the unknown. Have had the experience of arriving back at the airfield after
an hours rather nervous return from a retrieve. When we stopped the driver was
honestly surprised to find the bits of melted recap tyre hanging forlornly from
the casings. Fortunately the original casings had been good, and were still
partially inflated and nominally intact.

It had not occured to him that the "cheapest deal available" on tyres because he
virtually never used the trailer would not have the same capability as the
225x50 V rated rubber on his executive express, which has the power and weight
to ignore anything happening to a single seater in trailer dragging behind.

Dumb luck appears to be frequent, but I would advise against counting on it. Buy
decent tyres, tow at their rated speed and replace them once they start
weathering. It is a lot cheaper than the alternative.
