The two things that affect tires are time and mileage. Naturally, the compounds on tires have a limited lifespan as they begin to breakdown over time. The mileage on a tire is only a general indication of it’s wear and usage. Neither time nor mileage are accurate indicators of a tire’s usability. The reason for that is because factors such as tire storage and care can improve or diminish lifespan. Typically most tires are manufactured to last at least five years under normal circumstances. If your tires are older than 5 years, it may be a good idea to consider replacements.
Reading the sidewall and understand tire sizing options can seem difficult at first. Once you learn the basics of what these numbers and markings mean, it becomes much simpler. Oftentimes original equipment tires use standard sizing designations, such as 255/70R17. However, when upgrading tires, especially for the Jeep Gladiator, you may come across flotation sizing designations. These will typically read as 35×12.50×17.
Most tire manufacturers will give a suggested rotation interval. The OEM tire rotation interval for the Jeep Gladiator is 5,000 to 7,000 miles. Regularly rotating your tires is a great way to extend the life of your tires. Learn more about proper off-road tire rotation.
The Jeep Gladiator is a purpose-built truck. The best tires heavily depend on your driving style, temperature, and weather. For example, a driver who often drives on unpaved or off-road situations would require a different tire than a driver who only uses their truck for commuting.
There is no one answer to this question. Every truck and every tire require a different tire pressure. The best way to find what tire pressure is required is to check the driver's side door for a label that displays the recommended tire pressure for that vehicle. It's important to note that this recommendation changes depending on the load of passengers, as well a cargo load. Learn more about light truck load ratings.
Every tire has a UTQG rating that provides information regarding number of miles the tire is expected to last. However, this number is an estimate. How you drive your vehicle has a big impact on the life expectancy of a tire.
As stated above, the way you plan on driving your Jeep Gladiator will help you make a better decision on what tires to choose. If off-roading and driving on unpaved roads is a normal occurrence, then dedicated off-road tires may be beneficial.
