Your tire life appears to be rubbish. Barely 1,000 miles to wear down a FRONT tire?? My Continental GP 4 Seasons typically last well over 5,000 miles when used on the front end. The Schwalbe Big Apple 2.15" tires on my e-bike have over 2,000 miles on both tires and they're both still doing great, despite the rear tire being under quite a heavy load.
