Motorhome tyres are the number one priority when it comes to ensuring your vehicle is safe and legal, therefore it is imperative that you regularly check all four motorhome tyres and the spare tyre to ensure they are in good condition. Motorhome tyres that are on a stationary vehicle are always likely to age more quickly than those in regular use, and those motorhome tyres that are exposed to coastal air are also prone to faster aging. Watch our video here on how to check if your tyres need to be replaced.

Motorhome tyre care

First of all look out for any obvious signs of age deterioration such as cuts, lumps, embedded objects, sidewall cracking and carcass deformation. Also pay particular attention to the tread depth. Motorhome tyres, like all car and light commercial tyres are legally required to have a 1.6mm tread depth. However, in the interests of safety it is advisable to replace motorhome tyres well before they reach this legal limit.

There are some simple steps you can take to prevent early deterioration to your motorhome tyres, for instance consider covering the tyres to shield them from direct sunlight and, if possible, relieve the weight but jacking the vehicle up. If you cannot jack the vehicle up you can help prevent pressure damage by turning the tyres occasionally to prevent flat surfaces forming.

Tyre pressure

Making sure your motorhome tyres are set to the correct pressure is essential to the safety and stability of your vehicle. Incorrectly inflated motorhome tyres not only offer reduced handling capabilities and increased chances of a blowout but also wear out more quickly and increase the vehicles fuel consumption, costing you extra money.

The correct inflation pressure for your motorhome tyres can be found in your vehicle handbook. It is not the same as car tyres because the ply rating is much higher (up to six or eight ply as opposed to just two), as a result motorhome tyres can tolerate a much higher inflation, often up to 65 psi (car tyres are usually around 40 psi or less). Motorhome tyre pressure should be checked and adjusted, if necessary, when the tyres are cold. Never reduce pressures when the tyres are warm, because they could be too low when they cool down. This also applies to the spare tyre too; here the pressure should be set at the maximum required for your vehicle.

Punctures

The use of pre-puncture sealant is not recommended by tyre manufacturers. However, post-puncture sealants may serve a useful purpose in an emergency when its use can enable the driver to move the vehicle to a safer location. After suffering from a puncture it is also crucial to have the tyre on the other side of the axle examined as it may have sustained damage while bearing an extra load. Any tyre that has sustained a puncture and run, even for a limited distance, in a deflating or deflated condition is likely to have suffered internal damage and will be in need of replacement. etyres will always try and repair a puncture before replacing the tyre, so make us the first point of call should you suffer a puncture.

Tyre Impact Damage

When your motorhome tyre comes into contact with solid objects such as kerbs the force can cause the ply’s between the tyre sidewall to delaminate. The effects of such erosion can sometimes be seen in the form of bubbles on the tyre surface, this is caused by air escaping between the ply’s. When cornering, motorhomes can have a load factor of up to three tonnes, so it is not surprising that sidewall impacts can easily cause irreparable damage, and result in dangerous blowouts.

Overloading Tyres

Motorhome owners need to be especially careful to not overload their vehicle as this can greatly increase the probability of a tyre blowout. To safeguard against this, the UK tyre industry recommend that when choosing tyres, the maximum technical permissible laden mass (MTPLM) of the vehicle should not exceed 90% of the tyre load capacity as indicated by the tyre’s load index. MTPLM is the motorhomes maximum total weight allowable when full of people, equipment, pets whilst still being safe and stable. Most motorhomes will have a weight plate on them and the MTPLM is usually the first figure in the list, MTPLM can also be called the ‘gross vehicle weight’.

The tyre load index can be found on the sidewall of all motorhome tyres after the size coding and in front of the speed letter code. A typical example is 175/80/R/13 97T: 175 is the tyre width in millimetres; 80 is the sidewall height expressed as a percentage of the width; R indicates radial construction; 13 is the wheel diameter in inches; 97 is the load index; T is the speed rating. The load rating is a very important factor with all motorhome tyres. It is not sensible to compromise the handling and safety of your motorhome by fitting a regular car tyre instead of a properly load rated motorhome tyre. In fact in most cases this is actually a false economy because there is little or no difference in price. The compromise often occurs because the correct tyre is not available; ordering from etyres overcomes this problem, because we order in your exact tyre requirements. etyres are able to come to you at your home or caravan store six days a week to fit new tyres, repair a puncture and fit Tyron Safety bands

How old are my motorhome tyres?

Finding out the age of your motorhome tyres is important because even if the vehicle hasn’t covered a lot of touring miles and the tyres don’t look worn they will still have deteriorated. Like all tyres motorhome tyres will deteriorate with age and can become distorted if they are under-inflated. For this reason etyres and insurance companies recommend that motorhome tyres should be replaced before they reach five years old.

Follow these simple steps to find out how old your motorhome tyres are:

You can find the date of manufacture on the sidewall of all motorhome tyres as part of the DOT (U.S. Department of Transport) code found close to the wheel rim, see the image below.

DOT codes are tyre identification numbers

An example code is DOT A87C DEF 0102, the final set of four numbers are the date code. This four digit code shows the calendar week and the year of manufacture e.g. 0102 is week one of 2002. There are a small number of tyres that may not have a DOT code, in these cases the date of manufacture will still be shown elsewhere on the tyre, for instance if you see a separate group of letters and numbers such as 4202 this is definitely the 42nd week of 2002.

The correct tyres for your motorhome

The original tyres chosen for a motorhome are decided by joint consultation between the vehicle and tyre manufacturers. They weigh up all the information and take into account all aspects of operation. etyres advise owners not to make changes in tyre size or type without consulting the vehicle or tyre manufacturers to avoid detrimental effects on the handling and safety of the vehicle. The tyres originally fitted to your motorhome are usually of a “Light Commercial” (C) category. They are designed to cater for the higher loads imposed by motorhomes. Deviating from the original specification is likely to have an effect on the handling and general characteristics of the vehicle. Never replace tyres with ones of a lower speed rating or load capacity. Watch our video here on how to buy the correct tyres online

etyres also advise that having the same construction of tyres on all wheels is preferable for handling, however if this is not possible only tyres of equal size and service description (load index/speed symbol) and identical wheels should be fitted across an axle and carried as a spare.
