My idrive tells me to run 2.4 (35psi) bar all round.

I run more along the >100 mph recommendations (as I do hit those speeds with frequency) but don't go quite as high as they recommend. I think I'm at 36/40.

On my base X3M, the car suggest 41psi rear and 37psi front. I was at 51psi in all 4 corners from dealer when purchased. I reduced to 39 rear and 37 front, and made a world of difference.

I set same 33/38 per door jam but also reset the warning in the idrive menu. Haven't gotten any new notification but only put 100 miles since I updated.

To the folks getting idrive errors. You need to set the tire size spec in the config and reset it.

The tires are over inflated when the car is shipped to help slow down flat spotting while they sit. Dealers should be adjusting to proper spec but they don't always do it...

I have noticed that I Drive recommended tires pressures change as the tires warm up. There is a significant difference between cold and warm pressures measured by I Drive so I really appreciate this feature.

Does anyone have picture of the actual sticker (X3m LCI)? My idrive doesn’t show any values, just refers you to the sticker. Unfortunately someone has removed mine and they’re on back order with no delivery date.

Google search suggests 32/32 which appears to be different than the above.

Don’t go by the sticker, go by what’s in the manual.

I run 39/46 on my 2020 as recommended for >100 mph.

It’s not exactly smooth, but I’m a tough guy like that
