Simple review - Fantastic tyres really in every respect. Outperform the best Michelin Touring tires by a mile (no pun). Frankly, the best tyres I have ever purchased, and would highly recommend them to anyone who is looking for a higher end touring tyre, and whom doesn't want to pay the Continental price - you even get a better tyre than Continental with these Bridgestones. Bottom line, you get what you pay for, and irrespective of this rationale, you just get great value comparitively. I will never buy Michelin (or anything else for that matter) again after these.
Side note - Bridgestone in general; I purchased a set of Blizzaks a decade ago and they completely outperform ANY other snow tyre I've had before.
Just a great manufacturer.
PS, don't be fooled by 'Turanza with Serenity Technology' you have to get the 'Serenity Plus'.
