The Grand Prix 4000S was the reference tyre in the road market but now gets a facelift. 4000S II gets a Vectran breaker for unsurpassed puncture protection and Continentals advanced BlackChili compound for lower rolling resistance and increased grip.
 

Wet weather grip.

Invested in a set of these tyres to replace my Armadillo all seasons.

Fitted without issue, decided to go with 25, had 28s previously.

Initial thoughts were very good, seem to roll better and faster.

However went out this morning, there had been a little bit of early morning rain. Some of the surfaces were dry and some wet. Went to take a sharp right at the a T junction at a fairly slow speed and to my surprise and the rear wheel gave way. I had my cycling shoes on so could not stick my foot out like I would normally if commuting. The pedal scrapped the road but somehow I managed to right the bike. This knocked my confidence a lot and I slowed down when taking subsequent corners.
So I am not sure what to do now.

Should I buy a set of GPs all seasons and use these all year round and get rid of he GP4000 II.
Or put an all seasons tyre just on the back wheel (perhaps even a 28mm).
Or maybe reducing the trye pressures from the current 105 to 95 would provide better grip in the wet?
Or perhaps I was just unlikely this morning and there was maybe some oil on the road surface - tbh that's unlikely as not even many cars use the road.
Any thoughts / experiences / suggestions would be much appreciated.
Thanks

 dhb Slice 15L Rucksack
dhb Slice 15L Rucksack
A compact, 15L rucksack for riding the trails or commuting with a modest amount of gear. The dhb Slice 15L Rucksack has a slim design for a compact, nonrestrictive feel and high-vis finish for enhanced visibility in low lighting conditions.
 

Suitable for running?

I am looking for a small rucksack for cycling and running. Clearly this suits for riding but what about running,. Has anyone tried running with it? I really need something that is not going to move around much on my back.
