Why are tyres important?
Motorcycle tyre maintenance
Motorcycle tread depth
The legal limit for motorcycle tread depth in the UK for motorcycles over 50cc is 1mm across ¾ of the tread pattern’s width, with visible tread on the remaining ¼. For motorcycles up to 50cc the law requires that all the grooves of the original tread pattern must be clearly visible.
But why is tread depth important? Tyre treads are designed to give good wet grip, but the road surface also plays a significant role in tyre to road adhesion. In general, wet grip decreases as tyre tread patterns wear down and as the depth of surface water increases. Riders should take this into consideration and reduce speed in wet conditions.
Motorcycle tyres normally have tread wear indicators in the tread grooves and as these are approached, you should consider replacement. Once the indicators are level with the tread surface the tyre should be replaced.[/vc_column_text][/vc_column][vc_column width=”1/2″]
Motorcycle tyre pressure
Under-inflating (or overloading) your tyres may cause rapid shoulder wear, excessive flexing and deterioration of the casing. While over-inflating your tyres may result in accelerated wear, reduced road contact, and an increased susceptibility to damage. Not only are both of these scenarios deeply unsafe, but they will increase your fuel consumption and make for a less comfortable ride.
Inflation pressures should be checked once a week when the tyres are cold using an accurate and reliable pressure gauge.
Don’t forget that you’ll need to adjust your vehicle’s tyre pressure depending on whether you are travelling solo or with a pillion passenger, check your owner’s manual to adjust your pressure appropriately.[/vc_column_text][/vc_column][/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1738758962618{background-color: #FFFFFF !important;}”][vc_column width=”1/2″]

How to choose motorcycle tyres
Tips for checking motorcycle tyres
- Check your tyre pressures from cold at least once a week using an accurate gauge
- Inflate tyres to the level recommended in the manufacturer’s handbook
- Inspect tyres for cuts, bulges, uneven wear or objects embedded into the tread pattern and replace if necessary
- Check that your tread depth is not below the legal minimum of 1mm (for motorcycles over 50cc)
- Use dust caps to keep dirt away from the valve core and to act as a secondary air seal
- If your rims are cracked or bent, they should be replaced immediately
- Check that your tread depth is not below the legal minimum of 1mm (for motorcycles over 50cc)
- Replace old or damaged valve stems
- Select the correct type of tyre for your machine and riding style
- Check that both tyres fitted to the motorcycle are made by the same manufacturer and have the same tread pattern
- Make sure that your tyre has been fitted the right way round by checking the directional arrows on the sidewall
- When replacing tube type tyres always use a new inner tube
- Make sure your tyre/wheel assembly is balanced correctly
- Keep oil and grease off your tyres using detergent if necessary
If you are unsure on any aspect of tyre pressure or tyre condition, take your motorcycle to an approved fitting centre and speak to a qualified professional.[/vc_column_text][/vc_column][vc_column width=”1/2″]
Inspection and maintenance
Driving over potholes, kerbs and speed bumps, even at low speeds can result in the weakening or fracture of the tyre structure. Riders experiencing an in-service impact should ensure immediate inspection by a tyre professional. Lumps and bulges can indicate internal damage or a puncture and should be examined by a tyre specialist without delay.[/vc_column_text]
Common FAQs
Older tyres or those on vehicles that haven’t been driven for a while are more likely to crack, especially if they have been exposed to cool temperatures or left in uncovered storage.
Under-inflated tyres can also cause cracking, as under-inflated wheels cause more friction and as a result, more heat. Similarly, with the rubber stretched beyond what it recommended, over-inflated tyres can be susceptible to cracking.
Environmental conditions, such as extreme temperatures and prolonged wet conditions, can also contribute to tyre wear and tear. It is important to conduct regular motorcycle tyre maintenance to ensure you stay safe on the road.[/vc_toggle][vc_toggle title=”How should you ride a motorcycle when new tyres have just been fitted?” style=”square_outline” size=”sm” custom_font_container=”tag:h3|font_size:16|text_align:left” custom_use_theme_fonts=”yes” css=”” use_custom_heading=”true”]Motorcycle tyres need to be ‘broken in’ to safely remove the thin film applied when they are demoulded in the manufacturing process.
For the first ~100 miles with your new motorcycle tyres, you should drive slower than normal, avoiding heavy braking, leaning or acceleration.[/vc_toggle][vc_toggle title=”How do I avoid “squaring-off” my tyres?” style=”square_outline” size=”sm” custom_font_container=”tag:h3|font_size:16|text_align:left” custom_use_theme_fonts=”yes” css=”” use_custom_heading=”true”]Long journeys on motorways can cause the meeting of the tyre’s sidewall and tread to ‘square-off’, which gives a feeling of loss of grip when the motorcycle is used on winding roads. Often on long journeys motorcyclists switch from the motorway to fast A- and B-roads, without knowing their motorcycle’s handling is compromised. The squaring-off phenomenon will always affect motorcycle tyres because of their design, but if the motorcycle is being constantly ridden on winding roads squaring-off will take longer to occur, meaning extended tyre life.
The type of journey covered isn’t the only reason for squaring-off, as other factors can have an impact. Most notably the compound of the tyre and the original profile of the tyre when new. Some tyres have a flatter profile to start with while others can be very pointy. The ‘pointier’ they start out as, the more the squaring-off will become apparent as the tyre gets older.
Tyre pressures can also affect the squaring, with both under- and over-inflation causing problems. If tyres are underinflated this will cause squaring off, as would running them overinflated, but then the width of the ‘squared band’ around the tyre would be narrower as the contact patch would be narrower in the first instance.
Tyre design means there is no cure for the squaring-off phenomenon, but once they’re aware it might happen, riders can adjust their riding accordingly. It’s important that motorcyclists make allowances for any unusual handling characteristics their motorcycle might show when they leave the motorway. Keeping tyre pressures at recommended levels is one way to ensure safe riding, as is rider awareness.[/vc_toggle][vc_toggle title=”Can you mix motorcycle tyres?” style=”square_outline” size=”sm” custom_font_container=”tag:h3|font_size:16|text_align:left” custom_use_theme_fonts=”yes” css=”” use_custom_heading=”true”]It is illegal and dangerous to mix tyres of different construction on motorcycles in certain ways.
If in doubt a tyre specialist should be consulted, but it is generally recommended that both tyres on a motorcycle should be of the same construction and from the same manufacturer.[/vc_toggle][/vc_column][/vc_row][vc_row][vc_column]
