OK noticed my Carlisle Turf-saver NHS tires on the back of my cub have what looks like blistering on the sidewalls inside and out on the outer part. These tires are about 7 years old and are never in the sun or stored outside other than mowing. The muffler is at the rear of my Cub but I don't see how it would blister both tires in the same way. besides the exhaust shoot straight out the back.
I'm guessing they are cheap made-in-china (cheaper than the usual) tires? Anybody else see this blistering or deterioration on the sidewalls? Just noticed this and I know they didn't look that bad last year or bad at all?
Maybe a bad batch, my 21 year old tires on my LT4000 look new compared to these on the cub.
