When I needed new tires I checked at Camping World. The lady behind the counter said they had tires that would fit my RV. When I asked her for the date code on the tires she gave me a disgusted look and then reluctantly went into the back to check the date on the tires.
Les Schwab Tires also had a set that would fit my RV. When I asked for a date code the guy said come with me. We went to see the tires and check the date code. The tires were three months old, much newer than the ones at CW. I’ll bet she already knew the CW tires had shelf time on them.
