We have bought a trailer tent which didn't come with a spare wheel.
We have now bought a new wheel for the spare. But I cant help but think instead of the brand new wheel sitting there just in case why not replace the old wheels and have 2 new wheels on the trailer then use one of the old ones as a spare wheel.
Does this seem sensible or am I just making hard work for myself?

If you have bought one new wheel/tyre then yes, buy another & have 2 new tyres then you are ok for 5yrs. Your existing tyres may be much older. Over 5/6 yrs old & it's better to replace tyres as matter of course as they could be perished & fail at motorway speeds.
Having seen loads of trailers / caravans stuck on the hard shoulder due to their tyres giving up the ghost I would replace the tyres if they are coming up to 5 years old or have visible signs of deterioration such as sidewall cracking etc. You can age a tyre using the date code which is stamped on the sidewall usually in a 4 number code ie 3010 which means the 30th week of 2010.
Trailer tyres lead a hard life sitting still for a lot of time exposed to UV and being run on units with primitive suspension. It is usually a lot less hassle/stress/dangerous to change them as a consumable rather than on a how long can we go basis.
We have just replaced two 8" wheels and tyres on our baggage trailer at a cost of £52. As the trailer won't be used over the winter, we won't change them over until we come to use it next year.
