Well does the standard 3/32nds[?] of tread left apply to scooter tires? 4/32nds is an 1/8th and that's pretty thin in my book and would be the minimum for safety. Old school test is to put a penny in the tread and if the tip of Lincoln's head is = to tread depth or less it's time for a new tire. Some states they're also illegal at that point.
Don't know. I stick my finger nail in the groove and feel for how much rain grip I'll have on most tires.
I keep new Michelins under my family.
Beetles always rotted the sidewalls before the tread wore out.
Kenda tires, I am told, wear like iron -
and have about the same wet gripping capacity!For decades I have read that if a tire compound lasts a long time - it has traded off wet grip characteristics in the process.
I'm no tire chemist or engineer - but that makes sense to me.
So, I don't worry too much about how many miles my tires will last - being more concerned about things like temp & speed ratings, wet & dry grip & braking. (
Noise - I recently found was an issue with a set of Pirrelis and happily dumped them long before they were worn out! Stupid things howled at all speeds! But that's not an issue on scooters - too noisy to hear the tires!)
