To learn more, check out our article on tubes vs. This special bead is generally made of carbon fibre to ensure it stays perfectly put, which makes these more expensive. Tubeless-ready tires, especially for road bikes, require a bead that’s designed to stay in place without any stretching. Tubeless-ready tires are designed to be used without a tube, which means the tire needs to hold air without blowing off the wheel. Some tires even use multiple compounds in a single tire, so it can have a firm rubber in the centre and softer, grippier rubber along the edges. Not all rubber is created equalĮvery manufacturer has their own secret rubber recipe to create the right balance of grip, rolling resistance and wear resistance for their intended use. A lower TPI count results in a tire that isn’t as smooth and fast, but usually comes at a lower price and can be more durable. Higher-end tires will have a high TPI count, which creates a smoother ride, increase traction and roll faster. The TPI count of a tire carcass influences how pliable and supple it is. Under the top rubber layer is the carcass, which looks a lot like a piece of fabric. Whatever width you choose, make sure that your bike has enough clearance to fit the tire so it doesn’t rub on the frame. Not long ago, 23mm tires were all the rage but riders who’ve switched to wider tires haven’t looked back. 28mm tires are also becoming more common, as they give you more comfort on rougher roads with minimal drawbacks. ![]() The width that seems to have won the heart of most road riders is 25mm it offers a good balance of comfort, grip and speed. The tire width that’s right for you depends on the type of bike you’re riding: Road biking tire widths Less comfortableNot as grippy, since you need to have them at a higher pressure to prevent pinch flats ![]() Higher rolling resistance and heavier, which slows you down Lower rolling resistanceLighter and more aerodynamic More comfort and gripResist pinch flats better because of high volume inside the tire While you don’t want to buy a tire that is wildly wider or narrower than the one your bike came equipped with, there’s usually a little bit of wiggle room in either direction. You have a little bit of room to play with width. The width is the second number (e.g., 27.5 x 2.80 means a 2.8in. What is the best bike tire width?Įach tire on mec.ca shows the tire width measurement under “tire size” in the tech specs. Learn more about the best tire widths for your bike below. This number is expressed in inches for mountain bike tires and in millimeters for road tires. The second number is the width of the tire. Buying a tire with the incorrect diameter will make it impossible to install it on your wheel.Ģ. Start your search for a new tire with this number. for mountain bikes, and 700 for road bikes. The most common options are 26in., 27.5in. ![]() Look at the side of the tires currently on your bike to find out the size.ġ. Most modern bikes will be equipped with one of four wheel sizes, and you’ll need to know what size your wheels are so you can get tires that fit. The lugs directly affect the tire’s ability to stop and accelerate effectively. Worn-down lugs are rounded and much smaller compared to a new set of tires. On mountain bike tires, take a look at the centre lugs. If the tire looks squared off in the centre of the tread – instead of making a nice round shape – that tells you that a significant amount of tread has worn off. If there are no wear indicators on the tire, you can look at the tread, head on. Some road bike tire brands have wear indicators that show when your tires are past their prime. Tires that look dry and cracked mean the rubber has lost its elasticity and is a problem waiting to happen.If you’ve worn the rubber down to a point where you see any of the tire casing, you’re lucky to have made it this far! Get some brand new rubber.But if you see any cuts that are deep enough to show the casing, cause bulges, or allow to you see the inner tube, it’s time to replace the tire. Minor cuts in the tire aren’t too problematic.Knowing when to replace a tire is a great way to avoid being stranded on the side of the road or having to walk back to the trailhead.
