Ok so still waiting on T5a but have a general question. On averagely wet roads will I have to fit stabilisers or am I fearing a little too much life on 23mm of rubber? Only done a little bit on a friends at slow pace in the dry.
Be interested how others approach the autumn (fingers Xd I will get some miles in before then!) and the increased rain and greasy roads.

Just got to take it easy in the bends. Smooth movements. Not banked over so far when turning. You'll get the feel for it. Brake in a straight line before turns. Have fun

The main purpose of tread is to give water somewhere to go so that the tyre doesn't aquaplane, which is when a layer of water builds up between the tyre and the road and you are effectively trying to ride on water. In the case of a narrow bike tyre this is very unlikely to happen because the contact patch is so small in the first place.
The friction is dependent on the surfaces and the force acting downwards.

Thanks. That's peace of mind. Just need to get this bike soon!

Very unlikely, read somewhere that to get a 23C tire to aquaplane you'd need to be doing several hundred miles a hour. Slippery bits on the road are another matter of course.

I've never understood the concerns about the 23mm rubber. Sometimes I look at my front tyre and think it looks a little fat even.

The worst time is if there is a little scattering of rain after a dry hot period, as you get oils on the road, but a good shower gets rid of that pretty quickly. I do think you can read to much from articles and reviews when it comes to tyre performance in the wet, especially if the review is by a journalist rather than a physicist thats specialises in road friction coefficients. I would suggest it all about riding style when it comes to jurnos, or what they have been told to say
I was actually in Decathalon yesterday listening in while a kid was selling a white T3 to a middle aged guy, and the kid told him that the tyres are rubbish in the wet, and if he keeps them on the bike will go out from under him, I did keep quite when he recommended a harder compound tyre. ( none of my business, and what do I know) but when I say the guy outside I went over and told him the stock tyres will be fine so long as he does not try and take wet corners at top speeds.
For everyone else I would suggest you look at your tyres, if you have any significant scrubbing on the sides of your tyres, you may want to take it easy in the wet, if you have tyres that are perfectly worn square across the top, you probably have no problems at all, and for everyone in between, learn and know your limits

I doubt anyone will be cornering to the extent they wear the sides out. Otherwise what JTJ says, except I'd say angle of lean in relation to your line through the corners is the key factor, which combines with speed of course.
Speed in itself isn't necessarily dangerous, it's getting the forces involved unbalanced that catches you out, we are on a pretty fast moving rock anyway (apparently) - cue 'Universe Song'.

And also ... finding the limit best avoided unless you can slide in corners like Aldo Rossi, I think even he would struggle with a contact patch the size of a postage stamp.

Also - sort out the basics of cornering.
OUTSIDE pedal down and put your weight on it.
natural physics will transfer that weight to the tyres for more grip

We need to be a bit careful here as the title of the thread is 'rain', I doubt I'd be going for full on leans that require proper cornering techniques in the wet, I'd back off a bit and take it easy; this vid below is not bad, it sketches over line choosing a bit but no big deal, the bit at the end applies to wetter weather and winter roads. I speak from experience here, I have slid off my MTB in days of old when cornering - I remember it well, about 2002, went straight across the A4 Anchor Road in Bristol after flying down Jacob's Wells Road on a wet workday morning when trying to corner fast going left out the roundabout. Inky gunk all over me, gloves and trousers ruined; ended up laying in the opposite side of road with a car stopped in it's tracks and the driver looking at me like I was an alien; whilst I was dazed by crash and road rash. You'll likely only do it like that once.

White painted lines on and metal grids can get slippery when wet on cornering. I nearly came a cropper on a metal grid. It was located at the bottom of a hill next to a mini roundabout and I was turning right.
