I put new tires on my trailer about 3 years ago. I'm now getting some funky weary patterns and have been doing some research to try to figure out why.

While researching, I found this interesting site:

http://www.discounttire.com/dtcs/inf...rTireFacts.dos

I'm suspecting my wear issues are underinflation.......but here are my questions to you guys:

* The site above says you should only pull ST tires at a MAX of 65 mph. How many pull faster than that, and if so, how fast?

* The site above also says tires are usually only good for 5000 - 12000 miles. What do you guys generally get out of tires............I think I'm at about 7500 miles........

Thanks,

Geo
