I am in a situation where I am not sure what to do with my truck and hopefully INGO can voice some opinions. It is a 2011 F150 and I have had it for about 20 months. When I bought it there were brand new Michelin M/S2's on the front and over 1/2 worn Michelins on the back. Fast forward to now and the back tires are just about done for. What would everyone do if they were me? Luckily I only drive 12-15k miles every year on my personal vehicle. My options as I see it are:1. Buy 2 Michelin Defender M/S and run on the front. (They quit making M/S2)2. Buy the 2 cheapest tires I can find and run on the back to catch up with the Michelins on the front. Buy 4 new tires in the future once they are bald.3. Buy an all new set of 4 tires now, and try to sell the 2 good Michelins on ebay/craiglist/in person. I am looking at Michelin A/T2 or BFGoodrich T/A K02 currently.Help! Opinions?
