1. Knobs worn flat

If the tire tread has worn down to the point that the knobs are visible, it is time to replace the tires. You must focus your attention on both the center knobs and the outer knobs.

The knobs provide traction for climbing and braking in the middle. Cornering traction may be achieved thanks to the edge knobs. Both of these components are necessary to securely ride your mountain bike.

Take a look at the dials. If just one to two millimeters of tread remain on them after extensive use, it is time to replace them. If you want a measurement that is more precise than just looking at the tread on the tire, you may acquire a tire tread measuring gauge.

Look for knobs that have been ripped off. It is time to replace the tire if more than a handful of the knobs have been ripped off or chopped off.

2. Losing traction

Pay attention to what it’s like to ride your bike. Is it coming apart at the seams in some of the corners? Is it not grasping like it used to?

If you feel you are slipping and sliding in places where you used to feel locked in, it is time to replace the rubber. At 10-15% treadwear, some mountain bike tires begin to lose their ability to grip the trail.

3. Holes or gashes in the tire

Tubeless tire sealant can perform an effective job of maintaining the air pressure in a tire that has minor holes in it. If there is a significant hole or a cut in the tire’s sidewall, it is likely time to replace the tire. There are kits available that may be used to fix holes and gashes.

There are many who will use crazy glue to reattach the pieces of the tire. There is a limit to how far band-aids can go you. You should consider getting a new tire if the sidewalls of the one you have been severely damaged or if it has holes in it.

4. Bumps or blisters in the tread of the tire

Tires used for mountain bikes often contain many layers of rubber. Underneath the tread surface, there is something called a casing. Additionally, there could be a few layers of protection for the sidewalls.

Cracks of the rubber layers may be identified in a tire by the appearance of a hump or blister. When this occurs, the integrity of your tire has been compromised, and you should replace it. A good example of a bulge may be seen in the following image.

At first, this may not be particularly visible, but the unreliable bike handling will become more apparent as you ride more.

How to Extend the Life of MTB Tires?

Avoid using the brakes and sliding on asphalt, concrete, or other surfaces with high friction levels. Even if there are occasions when you truly don’t have a choice, avoid doing it until it is required. Here, proper inflation is essential. Verify that the tire’s applicable specifications set the pressure.

You may add bike parts to programs like Strava to keep records of them while tracking your miles. Even though you cannot predict with precision when a component will need to be changed, at least you are aware of the miles and active use hours.

Avoid the heat since your tires will wear out more quickly in hot temperatures. Keep your bike away from heaters; prolonged exposure to ozone might harm your tires. But don’t worry; I’m just referring to prolonged sun exposure. Your tires aren’t vampires, so they won’t blow up merely by riding on a sunny day.

If your tires need to be front- and rear-specific, switch them around. But keep in mind that the front tire needs additional traction. Although my dentist thinks it’s preferable to have a rear tire that slips out rather than a front tire. Although some riders wear down their rear tire before their front, this is an excellent method to get the most out of your wheels.

However, if you must purchase a new tire, put it on the front first and switch it to the back. Make careful to change the tires before the rear wears down too much if you truly want to save money.

When driving on rough or dry terrain, inspect your tires often since they will deteriorate more quickly. Replace any cuts in your sidewall as soon as possible if you find them.
