![]() That’s the reason why it can get away with running less tire pressure while still being able to perform. The big tire provides you with more protection as there’s more distance between it and the rim. Mountain bike tires come in many shapes and sizes. A high volume wide tire (like plus size or fat bike tires) is a basketball and a low-volume tire ball is a handball. Let’s talk about high-volume tires versus low-volume tires and why is it they require completely different air pressures. If you’re wondering, here’s how to accurately measure tire pressures on a bike. ![]() For reference, I weigh around 170 lbs fully geared up. It helps with puncture protection in rocky alpine terrain. And on my downhill rig I run 24 psi front and 28 psi rear with tubes and DH tire casings. I don’t need it to roll fast but grip to loose trails. I know back-to-back runs are not the most exciting thing ever, but doing that will give you the best types of comparisons and an invaluable understanding of how your bike feels under what conditions and at which pace.įor me personally, I found 23 psi front and 27 psi rear a good benchmark on the enduro bike with tubeless tires. To find your personal sweet spot it really helps to ride the same section of trail again and again. Rider weight includes all your gear including helmet, other protectors, or your backpack. This simple formula should be able to give you a good baseline for the right tire pressure for you. Finding your optimal tire pressure is trial and error. Table: Optimal mountain bike tire pressures in psi and bar for specific rider weights in lbs and kg.Įven 3 psi can make a noticeable difference. Tip:Bookmark this page on your phone for quick and easy look-ups out on the trail. There is an extremely simple, yet effective formula for both the front and rear tires using only your weight as a rider including all your gear. With so many possible combinations of tire sizes, suspension travel, rim width, riding styles and rider weights where do you even start? Glad you asked. It works great for Presta and Shrader valves and is just as good as the newer, more expensive D2X version. ![]() I personally use the Topeak Smartgauge D2 before every ride. I even wrote an entire article explaining why the correct MTB tire pressures are so important (including actionable tips).Īn accurate pressure gauge is critical to reliable, consistent tire pressures every time. To take full advantage of what your bike and tires have to offer, finding your optimal tire pressure is probably the single most impactful performance boost you can do on your bike that’s absolutely free. When going over rough terrain downhill or saving energy uphill even slight variations in the psi (or bar) have noticeable effects. It’s a metric that needs to be measured regularly as it’s crucial to the overall riding characteristics of a mountain bike. Setting the correct tire pressures on a mountain bike is the easiest way to prevent flat tires and also a free method to improve the overall performance of the bike.
