Maintaining the Ideal Tyre Pressure for Your Alfa Romeo 159 Tyre Pressure: Dos and Don'ts
- Do check pressures when tyres are cold (driven less than 2 miles).
- Do use a reliable gauge; gas station gauges can be inaccurate.
- Don't bleed air from hot tyres; pressures naturally rise when driving.
- Don't ignore the spare tyre check.
Winter vs. Summer Tyre Pressures
In winter, for the Alfa Romeo 159 Tyre Pressure, consider adding 0.2 bar (3 PSI) to the standard pressures if you are using winter tyres, as cold air causes pressure to drop.
