I ordered a set of the 205/65R15 Michelin XGT's today for my SD. Luke told me that the Green X Michelins were being discontinued soon by Michelin. He said that the XGT's have a fast steering response. (SOLD! Just what I've been looking for.) He did say they were a bit noisy, but since I have a diesel, I might not notice it too much. $89 each :) I'll let you guys know how I like them once they are mounted.

I have had the MXV4 energy and the XGTs, I now have the Yokohama AVS dbs on my W126 and they ride & handle better than the Michelins!!!!!!

Michelin needs to wake up to there expensive tires that are no better than certain other tires. They are riding on there legacy and the ride is going to stop one day! XGTs $85, MXVs $120 and the winner Yokohamas V rated for $70.

I would second James L's vote for the Yokohama AVS db, which I have on my daughter's 420SEL -- much quieter than the Michelins and cheaper as well.

Michelins may cost too much, BUT
 

over the last 42 years of tire buying, I have had zero cases of tread separation, uneven wear when the alignment was on spec, and sidewall breaks with them, whereas I have had some or all of the above with almost every other brand. I still often try other tires for a little handling advantage every now and then, but I keep coming back to Michelin; in fact I just finished emailing an order to TireRack (probably bought at least 50 tires there since 1980 or so) for a set of 225/60X14 for my recently acquired '85 300TD -- I wanted better turn in response, but couldn't bear the thought of abandoning those neat stock forged aluminum rims for something of larger diameter.
