Does Skye desire 14" or 15" tyres, and also what section width, profile and ply rating should they be?
The reason I ask all this is that I have quite a lot of 14 inch tyres lurking about which should mostly have some life left in them, subject to the usual caveats about being well advised to not use old tyres, regardless of how much tread they have left. I don't have anything on the fleet which uses 14 inch tyres and so they just hang about getting older.
Some of these are probably car types, e.g. Rover P6, Granada, etc. but I may also have some van ones and those will have been stored in the dark during my ownership, rather than just being left lying about outside.
Martin is due down here in December to rescue the Telecom van so should be able to have a quick look at my various tyre offerings on the same occasion and pronounce on their suitability for Commer 15/25 cwt applications.
