26I don't know that any tyres can grip on a wet man-hole cover. (They're the culprit in my only tumble in London too.) I think it's just part of urban cycling that you have to avoid man-hole covers when turning. (To those unfamiliar with man-hole covers in the UK they're often polished completely smooth by wear.)– thosphorCommented Oct 20, 2020 at 9:56

1Did you ever remember riding a Boris Bike over a metal plate in the rain while turning/braking ? If so, do you remember how fast you were going ? I expect, "slower than on the new bike" given the weight of boris bikes.– Criggie ♦Commented Oct 20, 2020 at 10:30

2There are definitely differences in grippiness between different tire brands. Reducing tire pressure won't help, grip is determined by force times area, and it's irrelevant whether you put lots of force on a small patch, or low force on a wide patch. However, as @thosphor says: It's your eyes that save you from falling on manhole covers.– cmaster - reinstate monicaCommented Oct 20, 2020 at 10:31

4@cmaster-reinstatemonica yes, you integrate the contact force over the contact area, but on real life surfaces the coefficient of friction is non-uniform, and a smaller contact patch samples a smaller area of road - if that patch is unluckily slippery you'll have trouble. Plus too-hard tyres can lose contact more easily due to bumps (e.g. the edges of the covers).– Chris HCommented Oct 20, 2020 at 10:52

2Don’t let out too much air, it’ll mess with the handling, which is bad especially considering how you crash while cornering. I thought Schwalbe was notorious for having high grip and poor durability? At least in the MTB world, Schwalbe tires grip much better than you would expect, but wear out absurdly fast (and are bloody expensive to boot).– MaplePandaCommented Oct 20, 2020 at 15:23

```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. mountain-bike), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
