Time to get new tires again but while the rear has worn very evenly (about 7500 miles), the front tire has a scalloped or cupped wear pattern to the left of center causing a need for replacement at about 3500 miles. I've never seen this before but if it were a car, I'd say it was a suspension issue. So, I'll replace the fork fluid but I'm not sure there is much else I know how to do. Any ideas out there? I'm running Shinkos 130/60 on the front and 160/60 on the rear. And yes, they were cheap. I am considering Pirelli Angel GT Sport as replacements. Thanks in advance!
