Two years ago, I had changed my tires to the popular 245/35/19 front and 275/30/19 rear in Michelin PSS. Upon recent inspection, my rear tires have almost completely worn out but my front tires seem to have plenty of tread left? I've been to the drag strip once on these tires and the rest has been mostly highway miles. I've heard that rear tires wear faster on rwd cars but I was not expecting this. I had an alignment performed shortly after the tires were changed as well.
Anyway, I was considering changing back to oem size for the rear tires and leaving the front tires. Will I notice any issues with this combination? Thanks!
