I wanted to replace my 5.30-12C’s with new tires. Bought 3 on Amazon.com. Got them home tonight and they are 1 inch thinner than the tires I currently have. A total blunder on Amazons part in my opinion. They are labeled 5.30-12. But don’t measure up. My current tires are 4” depth vs the 3” from Amazon. Hopefully will save someone else the headaches, they were Carlisle. Anyone else with this experience. Now I’m not trusting the 5.30-12 sizing.
