The orange Kymco I just purchased has new Maxxis tires and a new battery.
I beleive you can get city grip in your size in UK and Greese, since they are manufactured I don't understand why they don't import them to the US. I guess not a large enough market to bother with.
Not many (any other?) skinny-tired big-wheel scooters sold here.
That skinny front looks like it'd go 18,000 miles if I'd let it.
I don't have trouble with cracking or 'aging' with my tires. Maybe because of my gentle riding style, or the time of day I ride, and - if I'm not riding - they're parked indoors.
Frankly I think folks freak unnecessarily about tires failing due to age, as I can't recall the last time anyone reported an exploded tire. (on any vehicle)
If I was pushing a big bike at a ton while playing on the interstate - I'd likely rethink my attitude 😊
