* The vehicle's specifications: Your vehicle's owner's manual will specify the maximum tire pressure for your vehicle's tire size and weight capacity. This is the most important source of information. Never exceed the maximum pressure listed in your owner's manual.
* Load: How much weight is the vehicle carrying? Heavier loads require higher pressure.
* Terrain: Lower pressures (within safe limits) can improve traction off-road, but higher pressures are generally better for on-road handling and fuel economy.
* Tire sidewall: The tire sidewall itself will have a maximum pressure printed on it. This is the absolute maximum pressure that should ever be put into the tire.
To find the correct pressure:
1. Consult your vehicle's owner's manual: This is the primary source of information. Look for the tire pressure recommendations section.
2. Check the tire sidewall: The maximum pressure is printed on the sidewall. This is a maximum, and you should not exceed it.
3. Consider your load and terrain: Adjust pressure within the safe limits given in your owner's manual, based on the weight your vehicle is carrying and where you'll be driving. If you're unsure, it's generally better to err on the side of slightly higher pressure for on-road driving.
Do not rely solely on online sources or generic recommendations. Always prioritize your vehicle's owner's manual and the information printed on the tire sidewall. Using incorrect tire pressure can impact handling, fuel economy, tire wear, and even tire safety.
