Tyres are the only part of your motorcycle which are in contact with the road. Safety in acceleration, braking, steering and cornering all depend on a relatively small area of road contact. It is therefore of paramount importance that tyres should be maintained in good condition at all times, and that, when the time comes to change them, suitable replacements are professionally fitted.
It is essential that you refer to your machine manufacturer’s handbook when buying and fitting replacement tyres.
Changes in tyre size, type and construction should not be made without first seeking advice from the machine or tyre manufacturer, since fitting the wrong tyre may have an adverse effect on handling, safety and wear.
Motorcycle tyres which have been subject to use on rolling roads must no longer be used for subsequent, normal service. Use of Avon motorcycle tyres on a rolling road (Dyno) will invalidate the tyre warranty. All tests on rolling roads must be carried out with test tyres, special tyres reserved for maintenance purposes, or tyres which are worn out or downgraded.
Use of Avon motorcycle tyres on a trailer voids all warranties and no refunds will be given.
Running In Tyres
When new m/c tyres are fitted for the road, they should not be subjected to maximum power until a reasonable ‘running in’ distance has been covered. 100 dry miles (160km) is the recommended minimum (discount any wet miles covered).
Tyre should then be visually examined and their inflation pressure re-checked before riding.
Look After Your Tyres
What are the only things separating you from a nasty attack of gravel rash? That’s right, your tyres. And in order for your tyres to give you their peak performance, they need a bit of regular – as in every week ‘regular’ – care and attention. It doesn’t take long to check over your tyres; after all, there are only two of them and they’re very easy to get at. But by inspecting them carefully for damage and keeping a close eye on their pressures, you’ll not only get more performance and longer life out of them, you might well save yourself from a potentially serious accident. That may sound a little
melodramatic, but it’s the truth. The following guide tells you what to look out for and why you should do it. Once you’ve got into the habit of regular checks they’ll take no time at all – they could well save your life (as well as save you money in tyre wear and extra fuel costs) so please, read on.
Have you got the right tyre?
Just because a tyre will fit on your bike doesn’t mean it’s the right tyre. Check your bike’s handbook to see what the right specification should be, or if you’ve lost the handbook ask your local Avon dealer for help. The speed and load ratings for your tyres should be the same as the original fitment items – never fit a tyre of a lesser specification. And although it is possible in certain circumstances to fit a tyre of a non-standard dimension, always seek the advice of either your bike’s manufacturer or your Avon tyre dealer before doing so.
Pressures up to scratch? Maintaining the correct tyre pressures is critical to your safety, so never think, ‘oh, they’ll do’. Check in your handbook (or with your local Avon dealer) to see what’s right for the speeds you’ll be riding at and the load you’ll be carrying, then take the pressures when the tyres are cold – leave it an hour after you last rode the bike. The tyre pressure gauges in garages are notoriously inaccurate, so invest in a digital pressure gauge; they’re inexpensive and can be found in most bike and car accessory shops.
Correct pressures – Your tyre is designed to perform perfectly at a very specific pressure. Inflated correctly, it provides the optimum contact patch for superb roadholding and water dispersal, as well as giving good handling, comfort and lifespan characteristics.
Under-inflated – A tyre with too little air in it has a distorted contact patch, reducing its roadholding and ability to cut through water. As if that weren’t worry enough, the tyre’s carcass is forced to deal with stresses and strains it wasn’t designed for, which increases the risk of accidental damage. Tyre wear increases, too, and your bike will be unable to put down all of its power effectively – bad news on all counts.
Over-inflated – Too much air means you’ll wear out the centre of your tyre more quickly, which is going to hurt you in the pocket. Your bike’s handling will suffer, too, and there’s the distinct possibility of fracturing the tyre’s casing and badly
cutting its tread blocks – not to be recommended.
Use your eyes – Some problems you can see for yourself – cracks, bulges, splits, things like nails and stones embedded in the tread. Some of these things can be dangerous, so if you spot something potentially nasty, get it looked at by a
specialist at your local Avon supplier, and remove items stuck in the tread straight away; if left, they could embed
themselves further and puncture your tyre. And if there’s any evidence of the casing showing through the rubber of your tyre, replace it immediately – it’s dangerous and illegal.
Tread pattern – Although the minimum tread pattern depth is 1mm or 2/32 of an inch, it’s advisable to replace your tyres before they become that worn. If the tread pattern shows signs of uneven wear, check the pressures carefully and also check out the alignment of your bike’s frame and forks.
Valve cores and caps –
Pressure loss from your tyres can sometimes be caused by poorly
seated valve cores – try
tightening them down into place, or if they’re worn,
replace them. And remember that valve caps actually do a job
keeping dust from the valve mechanism – so try not to
