City Grip rear has been on my XTown 300i for about 5,000 miles. Today noticed some rear wheel funny feeling---Givi E-46 box, 8.5 lb Dog in it----careful check of tire, checking air pressure, look at tire....it is starting to wear square.....like most of the scooter tires on the market and still has 4-5000 miles in it. Fix=will replace with Michelin Power Pure SC, based on them and my experience with them on both Burgman 400 and SilverWing 600---they wore round right to the end---one went over 10,000 miles rear of Burgman 400.
As long time rider, I do not like funny feeling rear---when all other factors working. Big Givi box can also affect rear end feeling----I have small box and may put it back on. Dog still fits.
