Center line tire wear
 

I bought my 160 60 17 tires 6 months ago. And my center of tire is showing wire already and rest of tire still 90% its wearing in a forwards direction of the tire and jaggeds to the right the bac to center of tire..... what is my issue?

Hard to tell without seeing it. Sounds like you are going straight a lot with maybe lots of throttle. The jagged tread could be that your wheel is not straight or low air pressure mixed with hard acceleration.

Heres a pic of tire

This is only side of tire showing wire othe side is worn but only dead center. The tire is dirty cause i have dirt drive. But besides middle. The rest is good as new. Maybe i bought a cheap tire cause ive only had it 5months.

What kind of tire is it? How old is it (date code)? What pressure are you running? How many miles did you go in those 5 months? Are you doing burnouts?

It could also be to high of air pressure in the tire. What are you running? Manual says 42rear 36front when cold

Dunlop tire. No burn outs. Im currently running a 15t front and 43t back. But im considering got to a 45t sprocket on rear

Also curious what tire you are running. My 600 had a basically street legal track tire (don't remember what it was) when I bought the bike. Where I live, you have to ride at least 30 miles of interstate to get to anything curvy enough to get off the centerline, and that tire was toast halfway through the summer. I didn't run it quite as deep into the cords as yours, but once they show at all it's already overdue for replacement.

A friend of mine turned me onto the Dunlop Sportmax series. I have the Sportmax Roadsmart III, installed May 2018, with probably 2500 miles on it now. I REALLY like this tire. It has a hard compound in the center for longer life, and tackier rubber further into the lean angle for better traction in the corners. I don't ride track at all, but on windy mountain roads it's got plenty of grip for me. I get low enough to drag my toes and have never experienced any indication of the tire letting loose. I run a Sportmax Q3+ on the front for piece of mind, and it's looking like it'll last about the same as the rear.
