He doesn't want to say for obvious reasons. He got mugged for a no name tyre.
You shouldn't mix winter tyres and all year tyres on the same axle. I know that much. As these are for cold climates will they not deteriorate and wear much faster in the summer?
If you care to do a bit of research (and I mean just a bit) before posting you will see that the Speed 606 tyre mentioned is actually designed as a summer/all weather tyre; not a winter tyre. The comment I think a fellow poster made was that Gislaved appear to get very good reviews for their winter tyres, so one could assume that they might know a thing or two about tyres and therefore there other tyres might be reasonable.
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...
