Went to Discount Tire a week ago..Snow is now here and I am happy I got them..I have the Pirelli's Scorpion Snow & Ice 20" 275 & 315's rear...But that was not without some PITA days...

SHORT STORY: is to make sure if your X5 is an after 10/11 build to make sure you have the right TPMS part #.

LONG Story:
I had to deal with the Discount Tire Manager after my Sales Rep was convinced the BMW was defective after his TPMS set-up wasn't being recognized by the BMW. THe rep insisted I needed to go to BMW to resolved this problem and that my BMW was "defective" as his "highly sophisticated $500 hand TPMS-sensor" was detecting the TPMS, thus my BMW was defective! ; )
(Its a 2011 X5 35d with about 1500 miles 3/11 build)
I did not tell him yet that I had already gone to the BMW dealer that AM after getting yellow TPMS faults, with blinking yellow TPMS faults which the BMW SA said means the BMW isn't recognizing the TPMS (SA doubted they were installed at all).
After a heated discussion , I insisted I speak to the Manger, and only dealt with the Mgr after that , I kindly pointed out to the Manager when he showed me his Computer Order page that there was a second Part # for TPMS on X5 E70 with one column showing " 10/11 - " , that must be the right one and for Builds after 10/11. I confirmed this with the local BMW Tech Expert,which differed from that A.M. as that BMW SA and the Parts Dept said there was only one TPMS part # for the X5.

Well they put the newly ordered "10/11 -"'s on today and the TPMS indicator stayed on, so we thought we were screwed. I drove home and after a mile the "new" TPMS monitors were recognized and the Yellow TPMS icon finally went away.

Hopefully, I'm in the clear.
I chose Discount Tire as they offered free swap of winter to spring tire sets and vice versa for the life of the tires, which also carries to all locations in the country. ( I also got a Tire Ins for the RFT's as some rec'd on here).

Does this concur with others ?
I never saw any previous posts to specify the TPMS part # etc otherwise I could have saved some time.



P.S.
(I dont hold any anger towards Discount Tire, but there was more "frustration" and 3 trips invovled)
I had a driver rear RFT go flat after the first install by them too ; ) I now know what a a flat RFT sounds like (just like a car with a flat running on the road) I had not driven the X5 in 3 days after their install, I thought the tire looked low and after the AM and a cold front went by is when I then noticed it was a lot lower and now made noise.

I put air in it and it stayed inflated for the day, but then they replaced the valve and it stayed inflated.
Ive dealt with enough dealers, mechanics shops, and tire stores over the years to learn that sh*t happens. You just gotta stay calm and hopefully everything turns out OK after some sound logical analysis.
(Hopefully these new TPMS's stay fault-free)
