After 12 years on 2 wheels, 365 days/year including rain, wind, snow and ice, I have the following advices:
- buy new tires, any, and keep them properly inflated; throw them away when they are more than 30 months old or have more than 12-15.000 kms regardless of how they look, always change the pair
- learn how to drive, lean over, brake and accelerate when the road is wet
- have a lot of luck so you do not encounter obstacle you cannot avoid, oil spots, animals that run in front of you, pedestrians etc. (I do not know how to achieve this point though)
- wear helmet, gloves, jacket and have a good (life, injury) insurance
p.s. I have just modified my reply to post what is used on Agility: DUNLOP RUNSCOOT D207.
I have OEMs on People 250S; it has 12.000 kms and the front tire is more worn than rear which is strange. I plan to squeeze 3000 more and change them in half a year even though they will still look good.
For years I used Sava tires on my scoots.
I was a fan of Bridgestone Battlax BT020 tire when I had a bike. I could ride the bike in rain as if it is dry!
