Pleased to learn that you made the main gig. Good job you left plenty of time.
I second the idea of buying a space saver. Last Autumn, I bought one for Mrs F's Mini Clubman. The kit came in a fabric case which sticks to the boot carpet with velcro and includes a jack and wheel brace (jack is a tad flimsy but it does work). Less than 8 weeks after I got the kit, she clipped a concrete corner at the stables and put a whole the size of my thumb in the side wall of the tyre. No can of goo was ever going to get us anywhere. The space saver kit saved the day.
Our Discovery 5 came with a space saver spare wheel. I really don't like the idea of towing our two horses with a space saver on the car - trailer gross weight fully loaded is around 2.8T. When we bought the car at 2 years old, I asked the dealer about a full sized wheel to match those on the car. The sales chap, to his credit, replied: "You really don't want to buy one of those from me!". When I started shopping around, the Land-Rover price for a wheel on its own was £1100 ish. He wasn't joking.
I found one on eBay, without tyre, for £270. A couple of very minor scratches but no accident damage. A new tyre and valve later and we have a full size spare - which we have already used once as we got a slow puncture in Norfolk last October.
Oh the joys of motoring.
