I can't be bothered to get into an argument of pricing up alternative tyres, etc. as I have no doubt that for £25 or so more I could probably have got a better known brand fitted (particularly if going through a mobile place that comes to you), but that was never the question I asked or in fact am at all interested in.
All I was interested was in if anyone had an objective opinion of Gislaved tyres, and I think only one poster has pointed towards any actual reviews.
Frankly I have no more time to waste on this matter as it would appear there isn't really an answer and only experience will tell.
If it helps you sleep at night and boosts your ego, then yes, I got mugged, poor me...
