Periodically, I have posted the wear measurements for the Verdestein Quatrac5 tires on our 2014 RTL spyder.
I only do this as information showing OUR experience - yours may vary based on many factors :dontknow:
Oh Yeh........we always ride 2 up...and at the "Recommended" maxweight limit

OK.........now
Tire pressures front and rear are run at.... 17 PSI fronts and 18 PSI rear.
Spyder OD reads 56,872 today.
The front tires are 175x55xR15 from tire rack, mounted on rims by local tire dealer. 03/23/19 at 26,676 Spyder miles.
Tires currently have 30,196 miles on them. Tread depths in 32nds measured 3 places across each tire are 7/8/7 on the left and 8/8/7 on the right.
The rear tire is 205x60x15 from tire rack, mounted by motorcycle dealer (all major brands, who will do ANY work requested, including tire changes!) while doing requested annual maintenance work plus a few other items I wanted done. 10/27/21.
A VERY professional dealer to work with. 100 mi away, but it was/is worth it !
OD read 50,575 at tire install. Tire currently has 6297 miles on it. Tread depth reads all 8s in three places across the tread.
Hope this is useful tire info for someone.
