Just purchased a set of Michelin ltx ms2 tires for my Z71 Tahoe and was looking at the tread pattern and something caught my eye. With the white lettering on the outside the driver side tires have the outside lugs angled forwards. On the passenger side the tires have the lugs angled to the back. This is due to the tire being turned 180 from the driver side tires. I have 2 questions on this. The first being, why would Michelin build a tire that when mounted will have the tread lugs facing opposite ways? This does not make sense if say you are trying to gain traction in mud (for 4x4's) or channeling rain as both front tires have an opposite tread angel as do both back tires. My second question is when it comes time to rotate the tires the tires with the tread lugs facing forwards will now be facing backwards and the tires with the tread lugs facing to the back will now face towards the front. How will this affect the tire? Seems like Michelin should have built this tire as a directional tire with a separate driver and passenger side model.
