How to Check Tire Pressure on Your BMW 328i
Check cold (parked 3+ hours) with a gauge. Every US-market 328i (2007-2016) uses direct TPMS with a sensor in each wheel — ignore European-market advice about the indirect ABS-based system, US cars never had it. On 2012+ (F30) cars, iDrive shows per-tire PSI and temperature: Vehicle Info > Vehicle Status > Tire Pressure Monitor. Replacement sensors are generation-specific (pre- and post-March-2014 use different part numbers), so match the build date when buying.

What PSI should my spare tire be on a 2015 BMW 328i?
The compact spare tire (donut) for the 2015 BMW 328i should be inflated to 60 PSI. Check your spare every few months — it can lose air while sitting unused in the trunk. Compact spares are for temporary use only (max 50 mph, up to 50 miles).
Does tire pressure change with temperature?
Yes. For every 10°F drop in outside temperature, your tire pressure drops about 1 PSI. This is why TPMS warning lights often come on during the first cold snap of autumn. The opposite is also true — tire pressure increases about 1 PSI per 10°F temperature rise. Always inflate to the recommended 35/38 PSI when tires are cold.
