Replacing an 8 yr old tire, which has been on my scooter for 7 yrs.....and still has plenty of tread.
Three things to note, so far:
1) That dealer installed 19mm axel nut was a bear to remove! Glad I had an impact gun! White residue on the axel is old Loctite.
I'll wire-brush it off and use blue Loctite again.
2) 8 year old brake pads look great
3) both bearings feel smooth, and rubber dust seals look good - may reserve the bearings & only replace the dust seals & valve stem this tire change.
Buttered things up & reinstallation went well, for a Senior.
New tire born - Feb 2019.
