What PSI should a 19 inch low profile tyre be?
Small tyres (13–15 inches): Lower PSI, usually around 30–32. Medium tyres (16–18 inches): Standard PSI, 32–35. Large tyres (19 inches and above): Higher PSI, often 35–40. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi. Always check the car maker’s recommendations for the exact figures. Keeping your tires at the correct pressure ensures better gas mileage, safer handling, and longer tire life.Tire pressure between 32 to 35 PSI is suitable for most vehicles. However, one can go as low as 20 PSI (although that is not recommended). Anything below 20 PSI is considered a flat tire. PSI stands for pounds per square inch.But you shouldn’t go too much over recommended PSI. You can safely over-inflate tires by up to 10%. For example, if your tires have a recommended PSI of 35, you can go up to around 38 PSI without worry. Anything more than that is too much and not recommended.
