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 Defenders that are used for off-roading, you may come across flotation sizing designations. These will typically read as 35×12.50×17.
Every Land Rover Defender trim comes with specific tire sizes, usually ranging from 18 to 22 inches depending on the model and package. Always check your owner’s manual or the driver’s door jamb for the exact size that fits your Defender best.
RBP recommends inspecting your tires every 5,000 miles and replacing them every 30,000 to 50,000 miles, depending on tread wear and driving conditions. If you notice cracks, bulges, or uneven wear, it’s time for a new set to keep your Defender performing at its best.
Absolutely, you can use mud-terrain tires! They’re a great choice if you love off-roading or need extra grip. Just make sure the new tires match the recommended size and load rating for your Defender to maintain safety and performance.
The ideal tire pressure varies by trim and tire size, but it’s usually between 34 and 38 PSI. You’ll find the exact number on a sticker inside the driver’s door. Keeping your tires properly inflated helps with fuel efficiency, handling, and tire life.
Run-flat tires aren’t standard on most Defender trims, but you can fit them if you want extra peace of mind. Just remember, run-flats can affect ride comfort and off-road capability, so weigh your options based on how and where you drive.
Each Defender sub-trim, from the S to the X-Dynamic and V8, may have unique tire needs based on performance and wheel size. Stick with tires that meet Land Rover’s specifications for your trim, and consider your driving style—whether it’s city cruising, highway travel, or rugged off-roading.
