18" tire pressure

[rlsjr]

What is the best tire pressure to have on the X5 for the best driving (handling) and milage capabilities? I do realize that the tires (Mich) are rated for up to 49 lbs., but placing that much air in the tires would make the vehicle drift and not get the best handling.

I have 33-35 in mine. Also read my post in your other thread "Premium Gas" on your question about milage.

Yeah I've thought about going to 40psi myself. Shouldn't cause any drifting issues. I will say, though, thatif you're mainly driving in the city this won't do you any good. I don't spend much time at speed on the highways so the improvement would be minimal for the reduction in comfort.

Recently I've gone 2 psi higher than recommended in the manual. I now have it at 34 psi front and 35 psi rear. I have found the ride smoother than at 32 front/33 rear (this is on the Michelin Energy MXV4 Plus).

i go by 33 in the front and rears on the same Michelin Energy MXV4's

Suggested pressure settings are listed on the door jam on the sticker.

I go max tire pressure and have never had problems with "drifting" or anything. Sure the ride's a little firmer but that doesn't bother me. I'm not sure but the higher the tire pressure the less the rolling resitance should be, it makes sense. I go with 51 lbs on my general grabbers (295/45/20) and have never had problems even after 40,000 miles.

i had 40 in my BMW323. The local indy pointed out that increased tire pressure above suggested can be harder on suspension components and wheel bearings.

i now run 35 in warmer weather and 30ish in cooler weather to help with some grip.

I run 34 psi in all my 19" tires. Good ride for the summer season
