It seems to me that you would put extra work into getting the same
result, Either way you end up with 3 tyres that have to discarded long
before they are worn out.

I used top think that tyre failures were fairly random and caused by
external events, but a few years ago I changed my mind. One weekend
driving a subcompact (Fiesta) at 75-80 mph to the glider port I had an
explosive failure of a rear tire. Next weekend the other rear tire
failed in the same way. Both tyres were the same age, about 5 years
old. Too old to be safe in Arizona it seems.

My experience (in a very different climate in England) is that trailer tyres
get very iffy after 5 years or so due to sidewall cracking (normally
visible) caused by UV degradation of the rubber. I'd expect a spare tyre
kept on the inside of the trailer to last a lot longer than on the outside.
