Run Flats

[Ralphhall]

I have a 2012 X5 5.0 iDrive with staggered 275/40/20 frt and 315/35/20 rr.
What are you guys running to get best mileage?
Thanks

I literally just got 64k out of a set of Michelin Latitude runflats. Square set up tho, and I rotated occasionally and pay attention to tire pressure and alignments. 255/50-19. (Actually toyed with the idea of getting that tire in a non-RFT, but it is currently restricted by michelin to only Porsche dealerships....)



Also, finally, had to change the TPMS sensors- after 10+ years the batteries finally died. (was getting constant faults for the last 3,4 months)

I ran the Latitude RFT and they were an instant upgrade over the OE Bridgestones. Also square in 255/50R19. Later I went with the Michelin Premier LTX in the same size and now 255/55R18. Excellent, excellent tire, just not RFT. Don't know if the Premier LTX is available in staggered fitments.

Looked like a nice tire. Good load rating, so probably a decent sidewall so not squishy.


Assume you mean -19? Or did you change rims too?



Looked at the LTX. looks like the mileage will be pretty high too, 600AA rated. You'll beat your latitudes I bet.


Edit: I usually get an alignment with tires...but I need to replace Thrust Arm bushes, so holding off. Just got a new vertical press, look forward to doing bushes on NOT a bench vice!

I changed rims. Went to the snow package wheel - Style 210 - and tire since I got tired of switching between winter and summer tires. Just wanted a good all season. The Premier LTX delivers. Wears well, good traction . . .
