just got CPOed 2015 LX570. Has new Dunlops on the rear and the ones on the front has 3/4 of tread remaining. Anyone have experience on how many miles you normally get out of the stock Dunlops?

 

A very rough approximation would be 50K or so. It looks like PO didn't rotate the tires...had they been rotated every 5K to 7500 miles, there would be more or less equal wear front to rear. IMO the oem Dunlops are adequate on pavement, barely acceptable driving fast on a gravel road, and a somewhat scary in snow, rain, and / or a mixture.

 

Not an answer to your question, but I've got 116,000 miles on my 2009 LX equipped with Michelins. I am on my second set, and expect to get 10's of thousands of miles more before they need replacement. My previous LX 470, went through Dunlops twice as fast. If you need tires call Tire Rack and buy a set of Michelins.

 

^This.

I've not run Michelins on my 200, but I put a few sets (LT and AT) on several company-leased Chevy Suburbans years ago. 80-90K was easy, and that's with annual mileage ~70K. I'd throw Michelins on my 200 now, but I really prefer Toyo A/T II's which are now on my 200, my wife's '01 LX, and the Dodge 2500 diesel she uses to haul horses. Preference for Toyo is based on better off-road traction due to a bit more aggressive thread than the Michelins, 10 ply construction, and load range E.

 

Looks like based on tire rack reviews The Michlen LT A/T2 tires in the 275/55/20 size are the best replacements and only 200 dollars a tire
