I looked at their ad the other day and I didn't see an 18 at that weight rating. I will have to look at those again

A friend that used to be the supervisor for Metro in Seattle clued me into dates on tires. You have 6 years from production date of life. He said so many times they would get tires that were already 3 or more years old on their buses and would fail prematurely.

My rim cracked because they were not rated for more than 3500 lbs. When you get up close to 4000 lbs. its tires and rim maxes your getting to.

For anyone that truly wants to understand the answers to questions like this, I suggest going to your nearest university bookstore and go to the Civil Engineering section and get the text book for first year "Statics".

If you want it in condensed form, Eshbach's "Handbook of Engineering Fundamentals" is a great reference, but it condenses an entire book of the why to just 25 pages. I'll warn you, that level of information compression makes it pretty hard to read.
