I purchased a 175 65 R 15 84H tyre and 15” steel wheel from mytyres and it fits fine with the flexible boot floor flat. The hanging basket does not fully hang down but that’s fine and is very useable. The only point where the flexible boot floor does not fit is when it is raised and folded vertically! The rear retaining clip does not quite sit in the slot. The rubber on the tyre sits a little too high but only on the off side. This is a pretty esoteric setting. I don’t think this setting would generally be used anyway and I cannot see that I would use it. So that is fine too! I have left the carpet and the under carpet polystyrene filler in place, so without those it may even fit perfectly.
I purchased the wheel and fitted tyre through mytyres.co.uk which was also fine although I won’t buy a set of tyres from them. Firstly, their prices change daily. When I searched the set was £83.50 delivered, the next day I purchased at £89.00 (+ 6.5%), the following day they were 85.30. My luck! You can get cash back ordering through topcashback.co.uk Communication with mytyres is by template response which is underwhelming! The main thing that concerned me is that they delivered a higher spec than I wished. I ordered 175 65 R 84 H. They delivered 88 H XL which is a much higher Load Rating. OK for this purpose. I wouldn’t like to risk this variation for a regular set of tyres.
So the result is a full size spare and clamp (ex Honda) for £105 rather than a space saver from Honda for £190. I know this cost is more than the Rover 25 space saver route but the tyre is new (date code 2114) rather than an old (year 2002) tyre probably past its useful life now and certainly by when I plan to sell the car in 10 years!. Also the rolling circumference with the full size steel wheel is exact rather the Rover space saver which is a little small.
To round it off, I purchased an excellent wheel bag from
http://www.autogas-lpg.co.uk/37-spare-wheel-bag-lpg for +/- £10 delivered (or try dkmotors1 on ebay) into which I placed the spare and into which I can place the dirty tyre if/ when taken off the car. Also plenty of space for storing those important bits and piece!
