It doesn’t matter if you have a track bike, scooter, cruiser or road bike, they all have many components in common. One of the most important components of your machine is its tyres. Here at Zenith motorcycles, we know all about tyres and most importantly when it is time to change them. Motorcycle tyres are one of the most critical components for ensuring a safe and smooth journey. They are the only contact point between your bike and the road surface, making their condition crucial for performance and safety.
Knowing how often should motorcycle tyres be replaced can be tricky, but I have made a simple guide to help keep you and your bike safe. The photos used in this article are all from real MOT failures or tyre replacements we have had through the Zenith workshop.
Factors Influencing Tyre Replacement
Tread Wear: One of the most common reasons for replacing motorcycle tyres is tread wear. The tread provides the necessary grip on the road, and as it wears down, the tyre’s ability to grip decreases, especially in wet conditions. Most tyres have tread wear indicators – small raised bars within the grooves, see our previous post – What is the treadwear on a motorcycle tyre. When the tread wears down to these bars, it’s time to replace the tyre.
Mileage: On average, motorcycle tyres should be replaced every 3,000 to 15,000 miles, depending on the type of bike and riding conditions. Sportbike tyres tend to wear out faster, often within 3,000 to 5,000 miles, due to their softer compound designed for better grip. Touring or cruiser tyres, made of harder compounds, can last between 10,000 to 15,000 miles.
Age: Even if the tread is still in good shape, tyres degrade over time. The rubber compounds lose their flexibility and can become hard and brittle, leading to reduced traction. It’s generally recommended to replace motorcycle tyres every 5 to 7 years, regardless of mileage. The manufacturing date is stamped on the tyre sidewall as a four-digit code; for example, “2420” means the tyre was made in the 24th week of 2020.
Damage: Any visible damage such as cuts, punctures, or cracks in the sidewall or tread area can compromise the tyre’s integrity. If a tyre is damaged, it’s usually safer to replace it rather than repair it, especially if the damage is on the sidewall or if the puncture is large.
Riding Conditions: Riders who frequently ride on rough or off-road conditions may need to replace their tyres more often. Similarly, those who ride aggressively or carry heavy loads may also see faster tyre wear.
Tyre Type and Compound: Different types of tyres (e.g. touring, sport, off-road) and their compounds (hard, medium, soft) have varying lifespans. Softer compounds provide better grip but wear out faster, while harder compounds last longer but may offer less traction.
Signs That It’s Time to Replace Your Tyres
Worn Tread: Check the tread depth regularly. If it’s worn down to the wear indicators, it’s time for a new tyre.
Visible Damage: Look for cuts, punctures, cracks, or bulges. Any visible damage usually necessitates replacement.
Uneven Wear: Uneven wear can indicate alignment issues but also means your tyre is not performing optimally and might need replacing.
Vibrations or Handling Issues: If you notice unusual vibrations or if your bike doesn’t handle as well as it used to, the tyres might be the culprit.
Ageing: Even if not worn out, replace tyres every 5 to 7 years to ensure safety and performance.
Tyre squaring: Tyre squaring occurs when long journeys are undertaken with not much cornering (such as motorway riding) or if the rider is not confident to lean on cornering. The symptoms of a squared tyre is that the middle of the tyre has worn more than the edges creating a visible flat-looking surface on the centre tread of the tyre. Squaring can significantly affect the handling and traction of your motorcycle.
Performance Decline: A decline in performance, such as reduced grip or longer stopping distances, often signals worn-out tyres. This is particularly noticeable in wet conditions, where worn tyres can significantly increase the risk of hydroplaning. Check for Reduced Traction. If you feel less grip, especially when cornering or braking, it might be time to replace the tyres.
Longer Stopping Distances: If you notice it takes longer to stop than usual, tyre wear could be the culprit.
Maintenance Tips to Extend Tyre Life
Proper Inflation: Always maintain the manufacturer-recommended tyre pressure. Over-inflation or under-inflation can cause premature wear and affect handling.
Regular Inspections: Check your tyres regularly for wear and damage.
Balanced and Aligned: Ensure your wheels are balanced and aligned properly to avoid uneven wear.
Avoid Harsh Conditions: Whenever possible, avoid riding on rough roads or through debris that can damage your tyres.
Storage: Store your motorcycle in a cool, dry place away from direct sunlight when not in use. UV rays and ozone can degrade the rubber over time.
How Often Should Motorcycle Tyres Be Replaced Conclusion
We have seen some tyres in the workshop in a condition that would possibly render you speechless. I can’t help but shake my head writing this as it is something that continues to shock me. Some people view their motorbike tyres as an inconvenience when requiring replacement and will literally try and drag out a replacement as long as possible. I do understand the socioeconomic positions of my clients but what price can be placed on your or someone else’s life?
Replacing motorcycle tyres is a crucial part of bike maintenance that should not be overlooked. By paying attention to tread wear, mileage, age, visible damage, and riding conditions, you can determine the right time to replace your tyres. Regular inspections and proper maintenance can extend tyre life, but ultimately, when in doubt, it’s always better to err on the side of caution and replace your tyres to ensure a safe and enjoyable ride.
