Going on a camping trip in a couple of weeks so need space. Anyone any experiences with Tirefit sealant? I reckon Holts Tyreweld does the same thing and a good deal cheaper? Frankly the spacesaver wheel is such a faf! Until recently I never realised that you actually had to put air in the thing. It's a pain to deflate and fit back in to space, heavy and takes up a lot of valuable camping equipment space. What are your thoughts people for long term or temporary precaution.
