Jeep Grand Cherokee is well known for its off-road prowess. This popularity paved way for it to be introduced in the SUV market. Its high-performance powertrain, good looks, and comfortable interior made it a four-wheel drive worth owning. Aside from this, some maintenance work like adding pressure to your Jeep’s tires is also important so you do not get stuck in the middle of anywhere.
How tire pressure is measured?
Tire pressure is measured in two ways. The first is pounds per square inch (PSI). This is the most common method used by tire manufacturers and the auto industry. The second way to measure air pressure is a bar, which tells you how much air is actually in the tire. The problem with PSI is that it isn’t a precise measurement because it’s not standardized.
It can vary between tires of the same size, as well as between size designations for different cars that happen to have the same size tires. Bar units of measurement are more precise but are rarely used on passenger cars and trucks. They’re most often found in specialty racetracks and off-road vehicles.
What PSI should Jeep Grand Cherokee tires be at?
The right tire pressure for your Jeep Grand Cherokee tires depends on the year, model and trim level of your vehicle. The ideal tire pressure for your Jeep Grand Cherokee should be between 33 and 36 PSI.
You can find a tire pressure chart for all Jeep Grand Cherokee models below:
Tire pressure recommendations are also listed in your owner’s manual and on the door jam of your Jeep Grand Cherokee. If you drive a newer Jeep Grand Cherokee, you can also check the tire pressure monitoring system (TMPS) display on your dashboard for recommended PSI levels
Is 40 psi too high for Jeep Grand Cherokee?
No, 40 psi is not too high for your Jeep Grand Cherokee. The “PSI” you’re referring to is called the tire pressure, which is the measure of how much air is inside the tire. The manufacturer’s recommended tire pressure is always going to be the best place to start. It’s usually the right pressure for a Jeep Grand Cherokee.
It is important to remember that every model of car or truck has specific recommendations for tire pressure. Some vehicles have different recommendations for the front and rear tires, depending on how the vehicle is designed or its intended purpose. Additionally, having a blowout can cause a vehicle to rapidly lose control, which could result in an accident.
Should all 4 tires have the same PSI?
The answer depends, so “ideally” all 4 tires should be at the same PSI but for some cars and tire brands, it’s not. In fact, for many drivers, it’s actually impossible to have all 4 tires at the exact same PSI. The reason why is because of the different size tires on each corner of your car. The front and back tire are usually different sizes and usually, the front tire pressure is different from the back too.
That makes it impossible to match the pressure on every tire. So what should you do? Usually, there is an ideal PSI range that you should aim for on each corner of your car. For example, if your owner’s manual says you should have 32 PSI in your front tires and 33 PSI in the back tires, aim for 32-33 PSI in both fronts, and 33-34 PSI in both backs.
The most important thing is to stick within a 1-2 pound range of your target pressure. Small differences in tire pressure are OK as long as they are within the recommended range.
How to avoid over inflating tires
Over inflation of tires can be avoided by following some simple tips.
One should not over inflate the tires of the car. The amount of air that one needs to put into the tires should be according to the actual recommended level or pressure.
This is ordered by the manufacturer and it is usually displayed on a label inside the doorjamb.
The rubber in your tire can only handle so much pressure before it starts to bulge and flex. If you push it too far, you could end up with a blown-out tire on your hands that leaves you stranded on the side of the road.
To avoid this, check your tires with a pressure gauge every time you fill up for gas. You’ll need a dedicated pressure gauge for this task, as the ones at gas stations are notoriously inaccurate and unreliable.
Some digital gauges are more accurate than others, but if it’s off just a little bit, that’s all you need to know if you’re already at or near maximum capacity. If you’re still above 36 psi, let out some air until you reach your ideal level and check again until it’s perfect.
Conclusion
Having the correct tire pressure is one of the most important aspects of maintaining your Jeep. Not only is it necessary for safe driving, but having low tire pressure can lead to poor gas mileage and poor tread life.
