I’ve been running the Grand Prix 4 Seasons for about a month now as my Winter setup and covered lots of miles in different riding styles – hill climb time trial, extreme HC, sportive, commuting and social rides. So far I am very impressed!

As a tyre renowned for its grip and toughness I was also pleasantly surprised by its speed. I went for the 25mm version upping from my previous 23 tyre, thinking about safety but haven’t noticed any perceivable difference in rolling speed. In fact throughout my month I’ve only had positive thoughts for its running, and with improved grip brings confidence in bad conditions. I took part in a hill climb event recently which peaked at 25% gradient and unlike other competitors who complained about slipping I had no issue at all, partly helping me to PB the event…. obviously improved fitness helped too 😉

I’ve been plagued with punctures over the past year and touch wood nothing yet… I’ll keep you posted on my puncture to ride ratio! Thanks to its Duraskin cut-resistant layer and wear resistant ‘Max Grip Silica’ compound the tyre is designed for puncture resistance, good mileage performance as well as excellent adhesion on wet roads and at low temperatures.

Generally given 5/5 ratings across the web I also agree, and will be hard pushed to swap these off when the better weather arrives next year. Perhaps for the upcoming 4000 S II of course!!
