I have read so many tire threads over the past 8 years and often times wonder how did I get so lucky? My Montana 3400RL was a 2004 that I bought new and came with the "infamous" Tacoma tires. I had those tires on the coach for the entire 8 years I owned it and covered more than 50,000 miles. When I traded the coach, there was still more than 45% tread life left on them and they had worn so perfectly. I kept those tires at 80 psi regardless of load. The only other thing I did to the tires that I dont see many rv'ers do is I kept tire covers on the wheels anytime I was stationary over 2 days. I am not saying that my covering the tires for 8 years and stored the coach indoors during the winter was the cause of my success with the Tacoma's, but I sure would like to think it didn't hurt. With Keystone changing the frame to the new 12" frame on the 2013 Montana's, I wonder if we will continue to read all of the tire thread issues or not???
