I'm a firm believer in this -- although in general, do not think the Forteras are a great tire. I had OE Cross Terrains on a Mariner. Everyone raves about them. I thought they were mediocre at best. It's true that car manufacturers strike deals with tire manufactures. Not all Forteras (or many other OE tire for that matter) are created equally. There's a reason for this:
Check how many Fortera HL Edition there are in 245/65/17! They range from $129 - $175. Click on each, and then click the OE tab. First @ $129 is for Jeep. Second @ $142 is for Explorer, etc. etc. I can bet you the one for $175 (with NO "OE" tab) is the best.
PS. Sorry to hijack your thread. Your new wheels look great! Fortera are a great looking tire, and ride pretty good. I had them as OE on a Sport Trac. They would have needed replacing before 30k.
