I purchased a new Dodge Ram 2500 on September 8th, 2001. The truck had 75 miles on the odometer Michelin LTX A/S tires were the original tires that came with the truck. I never used a Michelin product before this point. But I noticed the truck had excellent ride characteristics with these tires. The winter was just around the corner but I found that I never had to worry because these tires always performed flawlesslsy in the worst weather. Another excellent quality about my Michelin tires was was how long the lasted. I was shocked to reach over 100,000 miles and still measure 5/32nds in tread depth. and in those 100,000 miles I never even had a flat or a puncture in any of the tires. Well, my choice for tires when it came time for replacement was obvious at this point, Michelin. I chose to go with the same exact tires that I had on the truck Michelin LTX A/S. and I experienced the same flawless year round performance for another 100,000 plus miles. By the time I was ready for my third set of tires for some reason Michelin discontinued the LTX A/S and I began to panic. Now what was I going to do? I could not switch brands now. Then I spoke to my tire dealer which is an official Michelin dealer and they assured me that the Michelin LTX M/S was a good replacement. I was a little skeptical at first because I liked the perfromance as well as the look of my Michelin LTX A/S tires. I took thier advice and purchased the Michelin LTX M/S tires and once again I got 100.000 plus miles of good solid year round performance. I have always been happy with Michelin tires, I am a mechanic and I am often asked which tires are a good purchase and I always recommend Michelin and refer to my history with them on my truck. That Ram has always been a special truck to me because it was the first new vechicle that I have ever bought, and the events that would unfold three days after I bought my new Ram on September 11. 2001 would suddenly give me a renewed appreciation for life and the freedoms we are blessed with in the United States of America. My Ram currently has about 450,000 miles on it and I am ready for my fourth set of Michelins. That truck has been good to me and has never given my any problems. My Michelin tires have been good to me too. I never even got a flat and my original Michelin LTX A/S spare tire is still mounted under the bed and still has full air pressure in it. My truck and my Michelins have taken me a lot of places. Somtimes a long way from home. But, I know that Ill always make it back because my truck has never let me down and neither has my Michelins
