Riding a motorcycle is all about freedom, adrenaline, and adventure. But whether you’re cruising on highways or zipping through city streets, your safety depends heavily on one important part of your bike: the tires. Motorcycle tires are the only point of contact between you and the road, so keeping them in top shape is required for a safe ride. So, how do you know when it's time to replace them?

1. Tread Wear

One of the easiest and most common signs that your motorcycle tires need replacing is tread wear. The grooves on your tire, known as tread, help with traction by gripping the road, especially in wet conditions. As these grooves wear down, the tire’s ability to provide proper grip and stability decreases significantly.

How can you check the tread? Many tires come with built-in tread wear indicators—small raised bars within the tread grooves. If the tread has worn down to the level of these indicators, it’s time for a replacement. You can also use the tried-and-true penny test: insert a penny into the tire’s groove. If you can see all of Lincoln’s head, it means your tread depth is too low, and new tires are in order.

2. Uneven or Bald Spots

Not all tire wear is even. If you notice that certain parts of your tire have significantly more wear than others, it may indicate a problem with your motorcycle’s alignment or suspension. Bald spots are also common in tires that have seen extensive use, especially for those who frequently corner aggressively or ride with underinflated tires.

Riding on tires with bald spots or uneven wear is extremely dangerous. These tires are more likely to lose traction, particularly in wet conditions, and could lead to skidding or a loss of control. If you see any bald or unevenly worn areas on your tires, don’t wait—replace them immediately.

3. Cracks and Dry Rot

Even if your bike spends more time in the garage than on the road, your tires can still degrade over time. Rubber naturally ages, and as it does, it can become dry and brittle, leading to cracks on the surface of the tire. This condition is commonly referred to as "dry rot."

Dry rot can compromise the structural integrity of the tire, even if the tread still looks fine. It typically appears as small cracks along the sidewall or on the tread itself. If you spot any cracking, it’s best to replace the tires as soon as possible, as dry rot can lead to sudden tire failure.

4. Bulges or Bubbles

If you notice a bulge or bubble on the surface of your tire, it’s a clear warning sign that something is seriously wrong. Bulges occur when the internal layers of the tire are damaged, often due to hitting a pothole, curb, or other hard objects at high speed. This internal damage causes air to leak into the outer layers of the tire, creating a bubble.

Riding on a tire with a bulge is extremely dangerous, as it can result in a blowout while you’re on the road. If you notice any bulges or bubbles, replace the tire immediately—don’t take the risk.

5. Age

Tires don’t last forever, even if they look fine on the outside. Most tire manufacturers recommend replacing motorcycle tires every 5 to 6 years, regardless of wear. This is because the rubber compounds break down over time, even if the bike isn’t ridden frequently.

You can check the age of your tires by looking at the DOT code on the sidewall. The last four digits of this code represent the week and year the tire was manufactured. For example, if the code reads “3019,” the tire was made in the 30th week of 2019. If your tires are more than five years old, it’s time to start thinking about replacing them, even if the tread looks decent.

6. Loss of Air Pressure



If you find yourself frequently needing to top up your tire pressure, it could be a sign that your tires are wearing out. Consistent air loss can indicate small punctures, aging rubber, or even a compromised tire bead (the part of the tire that seals to the rim).

Maintaining proper tire pressure is crucial for safety, fuel efficiency, and the overall lifespan of your tires. If your tires aren’t holding air as they should, it might be time to consider a replacement, especially if you’ve already patched them up before.
