Back end kicked out

[Andywinds]

During a wet Saturday ride the back of the bike slipped out and part of the rim ran on the ground. I run 23c slick tires Mavic Aksion. Is there a more sticky tire out there that would suit wetter conditions?

What you have is virtually a slick you would need to take corners gingerly with those when wet : Conti gp4000s or conti four seasons 25mm

Umm, there is no valid reason to have tread pattern on a bike road tyre so "slick" is the right design.
I dunno if the contis suggested are grippier though - quite possibly - but this is down to the rubber compound and not tread patter.

I live in a hilly area and in the wet I am getting very nervous. Forgot to mention my back end came out going downhill and I ended up on the wrong side of the road on a bend this was at a slow speed, so two issues on Saturday. The conti's are expensive but have good reviews.

I run Conti 4000s great tyres,but they will still kick out if pushed to hard in the wet..Know the limits of your chosen tyre and caution in the wet is my suggestion..

 

[Andywinds]

I'm more than happy to be cautious, thanks I'll order these. What size do you run?

nothing !

For various physics / engineering reasons it is impossible to get aquaplaning on a push-bike - and tread is to shed water to prevent aquaplaning - which you can get in a car hence car tyres need tread. However ill-informed consumers expect tread on a tyre, so people selling tyres put some tread on.

Off road is a different thing - and then you do need proper tread

I run 25mm..But I would investigate Conti more they do more of a winter based tyre, more puncture protection etc..
Do love the 4000s though. Commuter bike is shod with Conti Sport 25mm they are a tad cheaper,used all last winter no problems and no punctures ,hope I haven't invited the dreaded flat...

tread not needed on motorbike or bike tyres due to the curve surface and cannot aquaplane like car tyre with a flat contact area.

During a wet Saturday ride the back of the bike slipped out and part of the rim ran on the ground.

Cannot see how the rim would catch the ground because the back wheel slipped out. I could not even physically slide a tyre across the ground with my hands and get the rim to touch the ground and if it does the bike would be leaning that much, it would unrecoverable and be "an off". All the crashes I have had where I have had the wheel slide away its never happened including sliding sideways on the tarmac, so there must be a reason to what has happened for the rim to catch the ground and not entirely the tyres fault, underpressure, gravel, small pothole or crack in the road, combination of things etc

You will soon find out what the tread on a tyre does if you try taking a shortcut across the mown grass where dog walkers exercise their dogs alongside the cycle track because its congested with ignorant pedestrians on the approach for the Humber Bridge and pray heaven you do not puncture till at least you have had a few hours riding in the rain, otherwise, all those little skids you had on the grass which you thought was mud etc, may have same colour as mud, but does not smell like mud and is not mud and renders your tyre unhandlable to fix a puncture because of all the S*"!e stuck in the tread.

My tyres do feel a little under pressure at the moment. Maybe this was the reason?

Could be your tyres where rolling (sideways) when corning and not slipping as first thought

if they feel underpressure (by pressing fingers in?) then they are likely very very underpressure. Road bike (up to 25mm or so) should likely be 90+psi - maybe a good bit more, especially the back one.

Wider tyres somewhat lower - should have some numbers on the side. Ideally you want a track pump as it's very difficult to get tyres pumped up enough with a normal pump.
