Well....I guess "if" I drove in the rain, I would have to change the stock CST tires out. Too be honest....I like them well enough as I cruise only when it's not raining. You see...I don't rely on my S8 for real transportation. It's just a fun toy that I use when the outside condintions are good. Whne the start to wear-out, I'll score a decent tire. But...for now, I'll keep them.
Scolburn...Sorry to hear about dumping your S8! I know Vivo been using his stock tires for a while now & he's ok with them. As I recall...She been in the rain with them as well. You cannot expect Kymco to put on a Pirelli, Avon or any really decent tire for a budget scooter. Hell...My Kymco GT300i came with Maxxis tires & they are considering semi-budget!
