tire wearing on right only why
IT's a worn suspension part on that side and or alignment. Get the suspension looked at to get the worn part replaced, and alignment done and a new tire.
Check your air pressure first. Note how long the air pressure stays the same. If it drops at the end of the day you have a noticeable leak. If after a few days your tire pressure remains the same you may have an alignment issue, a possible toe-in or toe-out, but also could be a suspension issue.
