Just swapped to 22in staggered set up all seasons on a 20 M50I

When I went to to adjust the tire pressure, I noticed the summer/all season selection doesn't have any options for 22in rims.

The door insert seems way too low. The summer tire recommended setting is 37/45. I might be missing something but curious what the recommended setting is for others. I'm in the north east of that matters.

I also think something might've been off with the sensor at the last place I filled up bc filled to 37/45 but somehow, the cold reading is 39/47. Do I need to go let some air out, or is that ok?

friendly bump - would greatly appreciate any insight on this

I just use 38/44 on my '19 xDrive50i with those tires. I think your 39/47 is within spec, and I personally wouldn't let air out. However, I'm in Texas and drive mostly highway miles.

whats the benefit of running 39/40 on the fronts if the reccomended is 37? I'm assuming going slightly below 37 would be better from getting flats/rim damage since I'm in the northeast with horrible roads

i tend to run a few psi more- to lessen the possibility of sidewall damage, although sometimes not much u can do.
sidewall damage happens when the tire bottoms against the rim, the counter is more pressure instead of less pressure.

pressure for a given size should be the same regardless of all season or summer performance at a high level.

that's helpful, thank you. Is there a trade-off for increased pressure?

harsher ride, but if you're going from rft to non rft its not going to make that much of a difference. also if you overdo it, the center of the tread will wear faster.
a few psi isnt likely to make a big difference

ok got it. so if i'm in pothole heaven, it's prob safer to run a few psi over recommended to protect against damage but i'll feel the bumps more

yeah, there's only about 4.3" of sidewall on the 22s.
i tend to leave my 20" snows on till they patch up most of the potholes, cant beat almost 5.5" of sidewall!

Where did you end up purchasing them from? Searching in my area, looks like my only option is Discount Tire

Tire rack for me
