How to Scrub (Break) In New Motorcycle Tyres Safely 

We’ve all been there: after thoroughly researching and placing your order, your brand-new tyres have finally arrived. You can’t wait to burn rubber and try them out on your next big adventure.

Don’t be fooled, though.

While it’s easy to let excitement take over, you must take safety into account. Do the most important thing any biker should do: scrub in your new motorcycle tyres. 

Why New Tyres Have Less Grip

There are many benefits to investing in a new pair of motorbike tyres. However, it may come as a surprise that a brand-new tyre – fresh off the production line – has less grip than a slightly worn one.

The science behind it?

You might assume the slipperiness is due to Mould Release Agents: the tyre manufacturer's equivalent of grease in the cake tin used to help tyres pop out of their moulds. While this is true for many tyres, some premium manufacturers now use high-tech coated moulds that don't require lubricants.

However, even ‘clean’ tyres need scrubbing in – coated moulds solve the sheen problem, not the two issues below. This is because:

1. Surface Smoothing: A brand-new tyre is microscopically smooth. It needs mechanical keying—the process of the road surface scuffing the rubber—to create the friction required for grip.
2. Structural Settling: A tyre is a complex mix of rubber, steel and fabric. The first 100 miles allow these internal components to settle and ensure that the tyre performs exactly as the engineers intended.

Golden 100-mile rule

Now that we’ve established why you should scrub in your motorbike tyres, you’re probably wondering how long it takes to do so.

No need to wonder: the industry standard for scrubbing in, or breaking in, a tyre is roughly 100 miles (160 km).

During this time, which some call the settling process, there are a few precautions you’ll have to take when riding:

• Avoid reaching maximum lean angles or applying maximum power until the 100-mile threshold is met. Gentle cornering, gradually ramped up as the miles increase, is the way to go.
• With that aforementioned mould release agent, your new tyres will have longer stopping distances. As a result, you should leave extra following distance for smoother, more reliable braking until the release agent has worn away.
• In addition, you should be especially cautious when it’s raining. Water on top of a fresh mould release agent is a recipe for loose grip and crashing.

Front tyre vs rear tyre: do they scrub in differently? 

Your front and rear tyres don’t scrub in at the same rate, and treating them identically is one of the most overlooked mistakes riders make.

The rear tyre carries the drive force and the majority of your weight under acceleration, so it tends to scuff in faster. This happens particularly down the centre of the tread, where most upright riding takes place.

The front tyre does most of its work under braking and at lean, but sees far less centre-tread wear early on. This means the sides of the front tyre are often the last part of either tyre to be properly scrubbed in – exactly where you need grip most when cornering. Be extra cautious increasing lean angle on the front until you’ve covered the full 100 miles, even if the rear already feels settled.

How to properly scrub in new tyres 

Dos include:

• Do check your pressures: Always ensure they match the manufacturer’s cold-pressure specifications. There’s no separate ‘scrubbing-in pressure’. Running your tyres a few PSI under spec doesn’t speed anything up, and only adds uneven wear and handling vagueness while you’re trying to learn how the new tyre feels.
• Do focus on heat cycles: A heat cycle is one full warm-up-and-cool-down of the tyre. Ride for 15–20 minutes to get the tyre up to working temperature, then let it cool completely before your next ride. Aim for several short heat cycles across your first few outings rather than one long, hot ride – this helps the rubber cure evenly and settle into the carcass.
• Do be progressive: Ensure you slowly increase your lean over several journeys.

Don’ts include:

• Don’t use chemicals: Never use ‘tyre shine’ or cleaners on the actual tread surface.
• Don’t use sandpaper: Some people try to ‘scuff’ tyres manually; this is uneven and unnecessary.
• Don’t ‘Full Send’: Avoid heavy acceleration or emergency-style braking for the first few days.

Don’t just ride straight 

One of the most common mistakes riders make is riding in a straight line to ‘get the miles done’.

That’s not enough. 

Your tyres need to be scrubbed across their entire surface, including the edges. 
This means gradually introducing lean angle in a controlled and safe way. 

Use familiar, dry roads or roundabouts to slowly work the tyre from the centre to the sides. A quiet route with a mix of roundabouts, gentle bends and varying speeds will scrub a tyre in far more evenly than a single long motorway run. A motorway run mostly wears the centre strip and leaves the shoulders untouched.

Scrubbing in safely in the wet 

UK weather being what it is, you probably won’t get 100 dry miles in a row. Here’s how to handle it if you must ride in the rain during the break-in period.

Reduce your lean angle further than you would on a scrubbed-in tyre, as the combination of a fresh mould release agent and standing water dramatically cuts available grip. Increase following distance even beyond the extra margin already recommended above, and avoid painted road markings and drain covers where surface grip is already reduced. Stick to lower speeds too. If it’s genuinely wet, consider extending your break-in period slightly rather than pushing through the full 100 miles on schedule – there’s no downside to taking it slower.

Debunking common scrubbing-in myths 

A few myths persist around speeding up the scrub-in process. None of them hold up:

“Sandpaper or a scouring pad scuffs the tyre faster.” This roughens the surface unevenly and can damage the tread compound in patches, leaving some areas over-scuffed and others untouched.

“Tyre shine or cleaning chemicals help remove the release agent.” Most of these products leave a residue of their own, which can be just as slippery as the mould release agent you’re trying to get rid of.

“Straight-line miles are enough.” As covered above, motorway miles scrub the centre of the tread while leaving the shoulders completely fresh – exactly the part of the tyre you rely on mid-corner.

There’s no shortcut. Progressive, varied riding over the full 100 miles is still the only reliable method.

Different bikes, different approaches 

Compound hardness varies significantly by tyre category, which affects how scrub-in feels in practice.

Touring tyres use harder, longer-wearing compounds and tend to scrub in more gradually – don’t be surprised if they feel slightly less planted than a sport tyre even after 100 miles.

Adventure/dual-sport tyres often have a more aggressive tread block pattern, so pay particular attention to progressive lean on tarmac, where block movement can feel vaguer until the tyre has settled.

Sportbike tyres use softer compounds that generally scrub in fastest, but also lose that fresh mould release layer more quickly. Don’t mistake early grip for full break-in – still complete the full 100 miles.

Track days: why you can’t skip the road miles 

Never fit brand-new tyres and head straight to a track day. Track riding involves sustained high lean angles, hard braking and rapid heat build-up – exactly the conditions a fresh tyre isn’t ready for.

Complete the full 100-mile road break-in first, ideally including a mix of dry and (carefully managed) wet riding so the tyre has seen a range of conditions. Tyre warmers can help bring a scrubbed-in tyre up to temperature safely trackside, but they’re not a substitute for road-based scrubbing. Warmers maintain heat; they don’t replace the mechanical keying and structural settling that only comes from miles on the road.

Choose tyres from trusted manufacturers 

Not all motorcycle tyres are created equal. Leading manufacturers invest heavily in research, materials and performance testing to ensure consistent grip, durability and safety.

Whether you're commuting, touring or riding aggressively, choosing a trusted brand gives you confidence from the very first mile – especially during the crucial break-in period. Break-in characteristics do vary slightly by brand:

• Michelin – Known for excellent all-round performance and longevity. Michelin recommends a gradual break-in and publishes its own rider guidance covering the process in more detail. 
• Bridgestone – Strong grip and innovation across sport and touring ranges, with a compound structure that typically settles within the standard 100-mile window. 
• Pirelli – A favourite for performance and track-inspired tyres; softer sport compounds mean the surface sheen wears off quickly, but full structural settling still takes the full break-in distance. 
• Dunlop – Trusted for durability and consistent road feedback, with a break-in feel that’s generally described as predictable and linear. 
• Continental – Advanced technology with a focus on safety and control; Continental’s touring compounds tend to favour the more gradual end of the break-in curve. 

Metzeler is also worth a mention for adventure and touring riders – its coated-mould process reduces surface sheen, but the same structural break-in period still applies.

Always check the manufacturer’s own fitting and break-in guidance alongside general advice like this, as recommendations can vary slightly between individual tyre ranges.

The finish line

Once that oily sheen has disappeared and the rubber has a dull, matt-grey finish, you’re good to go. Your tyres are now operating at their peak performance levels, providing the safety and efficiency you bought them for.
