Robin do you have shares in TyreSure or some other vested interest?
....Why do you think that?
The TyreSure is not well known and someone might be grateful for discovering it here.
I'm an enthusiast and express my enthusiasm for anything and everything I particularly like. So, as I find the TyreSure very useful I share my enthusiasm for it so that others can check it out for themselves and perhaps enjoy having one too - It's entirely up to them. No financial vested interests whatsoever in any of the products I enthuse about. I have to say that sometimes I feel a bit irritated that some people make such assumptions - Usually the same type of people who never express much passion about anything unless it's negative - It's unfortunately a very typically English trait I'm sad to say.
