Left Front Tire 10 degrees hotter than the rest

boostm3 · 04-07-2023, 06:29 PM

Ive been noticing that, pretty consistently, after driving about 10 minutes down here on the hot Florida roads, the driver side front tire is running about 10 degrees hotter than the two tires on the passenger side, and about 6-8 degrees warmer than the drive side rear.. Does anybody have an explanation that could account for what's going on?

That's where the driver is.

Is the sun on that side of the car when you drive? Maybe some excessive toe?

Apparently the left side radiator throws a lot more heat than the one on the right side because it’s part of the engine cooling system. The one on the right side is part of the charge cooling system. The charge cooling system doesn’t have to deal with anywhere near as much heat as the engine cooling system.

OP has an OG M2. It only has one cooling system unlike the M2C.

That might mean there’s only a secondary engine cooling radiator on the left and nothing on the right? I think my N55 135i was like that.
