Caravan tyres and 4×4 tyres won’t be attractive, however they’re important for touring safely and reliably. It’s a cliché, however tyres are the one contact between your car/caravan/trailer and the highway. So, realizing as a lot about them as potential is important.
There are three predominant varieties of tyre patterns used on 4×4 and caravan tyres: Freeway Terrain (H/T), All-Terrain (A/T) and Mud-Terrain (M/T) tyres. There are additionally three predominant varieties of tyre development: Passenger, Business and Gentle Truck. Caravans have a tendency to come back with Business tyres, A/Ts or M/Ts.
Caravan and 4×4 tyre sorts defined
Let’s take a look at the advantages of every tyre sort.
Freeway Terrain tyres
Freeway Terrain tyres are comparatively quiet and easy and sometimes last more than different tyre sorts. They’ve a high-speed ranking and comparatively mild sidewall development. With a tread sample like a ‘automotive’ tyre, these tyres present the most effective on-road traction on your caravan or 4×4. Freeway Terrain tyres are fitted to most new 4×4 wagons and a few 4×4 utes too, and are marked as Mud and Snow (M+S) tyres, which pertains to their tread sample being barely extra open than an everyday passenger-rated tyre. If you happen to limit your self to on-road driving and towing, then H/T tyres will do the job high quality.
All-Terrain tyres
What precisely defines an A/T tyre is determined by how the tyre producer has designed it. Some A/Ts will provide a tread sample and carcass development much like a H/T tyre, whereas others can have a extra aggressive (blocky) tread and stronger development nearer to an M/T. Usually the A/T tyre can be marked as ‘M+S’, which implies it has a extra open tread sample than a normal passenger tyre.
Mud-Terrain tyres
Mud-Terrain tyres are the heaviest alternative on your caravan or 4×4. They’ve a stronger development and have a blocky, deep tread sample. In addition they have a low-speed ranking and a excessive load ranking. Their tread sample is designed for biting by means of mud, and so they provide good grip in different off-road conditions, akin to climbing rock steps.
Passenger-rated tyres
Of the tyre development sorts, Passenger-rated tyres are the least puncture-resistant however are additionally the lightest and infrequently most cost-effective to purchase. As well as, Passenger-rated tyres have the very best velocity ranking. Some H/T tyres are P-rated. You may inform as a result of you will note a ‘P’ prefix on their tyre dimension (written on the tyre itself), akin to P225/75R16.
Gentle Truck
Gentle Truck (LT) tyres on your caravan or 4×4 have a stronger carcass in order that they will meet the load necessities of sunshine vehicles. However how puncture-resistant they’re can fluctuate. Gentle Truck tyres can be found in A/T, Business and M/T tread patterns.
Business
Because the identify suggests, LT Business-rated tyres are supposed for industrial car purposes the place the car’s excessive load-carrying necessities necessitate a heavier development tyre. They normally have a easy on-road or typically a extra open Mud and Snow tread sample and don’t have a high-speed ranking. Their heavier development provides the next load ranking and higher puncture resistance than passenger tyres, making them perfect for heavier caravan tyres. Determine these tyres by a ‘C’ suffix of their tyre dimension, for instance, 185R14C.
The most effective compromise – on your 4×4 tow car tyre
An All-Terrain tyre in LT development is an efficient compromise on your 4×4 tow car for each on-road driving and towing off-road. Whereas A/T tyres sometimes have a decrease velocity ranking than an H/T tyre — usually between T and H – that is nonetheless past the very best velocity you’ll be able to legally tow at (see speed-rating chart under). In addition they have the next load ranking and extra open, aggressive tread sample for higher off-road efficiency.
A/Ts can have a extra puncture-resistant, extra strong development too. Examine the tyre specs on-line or on the tyre sidewall — eight- or 10-ply scores are finest for cover in opposition to stone injury and sidewall staking.
If you happen to’re going to be slipping and sliding on a muddy observe, a very good A/T tyre goes to do nearly as good a job of preserving the van straight as an M/T in most conditions. If you happen to’ve obtained the trailer making an attempt to jack-knife on soapy mud, you then’d need to ask your self why you’re dragging it by means of there within the first place.
Caravan tyre – Mud vs Business vs All-Terrain
Many on-road caravans are fitted with Business-rated tyres, and they’re the most effective compromise for such a van by way of having enough load ranking, value, and provide an enchancment in puncture resistance over P-rated tyres.
Mud Terrain tyres on a caravan are overkill for many tourers. They usually value greater than different tyre sorts, their added rolling resistance will add to towing gas consumption, and so they provide much less grip on the highway – particularly within the moist. As they aren’t pushed wheels, the little off-road grip benefit in having M/Ts as a substitute of A/Ts on a caravan might be felt in lateral traction.

Match health
When touring in distant areas, it’s helpful to have your 4×4 and caravan fitted with matching wheels and tyres. If you happen to get a number of punctures or broken tyres or wheels, you have got multiple spare to go round to go well with both car or van. This set-up requires a trailer to be fitted with the identical stud sample, offset and tyres with the identical rolling radius because the tow car.
Sizing up the choices
You may improve total tyre diameter by as much as 25mm legally, which provides improved floor clearance and infrequently elevated tyre choices. Take a look at tiresize.com to see what you’ll be able to improve tyre dimension to legally.
The writing on the wall
The sidewalls of your 4×4 and caravan tyres include a lot of helpful details about the tyre dimension, velocity ranking, load ranking, and even the way it must be balanced.
Be a part of the dots
Questioning what the pink and yellow dots imply in your brand-new set of 4×4 or caravan tyres? When tyres are made, they aren’t completely balanced nor completely spherical. The pink dot on the tyre sidewall marks the purpose the place the tyre is the lightest on its radius, and due to this fact the tyre fitter ought to align this mark with the wheel’s tyre valve — which is the heaviest a part of the wheel. When the tyre is fitted this fashion, it would want fewer weights to stability it.
The yellow dot marks the tyre’s excessive level — and this mark must be aligned with an indent on the wheel, which marks its low level (as a result of wheels are usually not made completely spherical both).
Studying between the traces
Tyre producers say that tyres solely have a helpful lifetime of between 5 and 6 years earlier than the rubber deteriorates and turns into harmful. Meaning the danger of a complete tyre failure in your 4×4 and caravan — a blow-out — will increase exponentially because the tyre reaches 5 years outdated, whatever the quantity of tread remaining. To learn the way outdated your tyres are (or how lengthy your new set of tyres have been mendacity round), search for a four-digit code on the tyre sidewall similar to the week and the yr it was made. For instance, a 4718 code means the tyre was made within the forty seventh week of 2018.
Scores matter
Like many elements in your 4×4 and caravan, tyres are designed to take a most weight, and legally, their load ranking should meet or exceed the Gross Automobile Mass of the car or Gross Trailer Mass of the van. When changing tyres (or for those who’ve simply purchased a used tow car or van), verify the scores are appropriate. For instance, in case your tandem-axle van has a GTM of 2000kg, every of the 4 tyres ought to have a minimal index variety of 90 (equating to a 600kg load ranking for every tyre).
Roll them round
Tyre rotation is crucial to even out tread put on, particularly for the 4×4 tow car, which is able to make the tyre set last more and must be carried out each 10,000km. You need to rotate tyres so that they put on evenly, and also you’re not left with tyres which have tread remaining however are too outdated to make use of (see above). Supplied the tyres are all the identical dimension with the identical load ranking, the spare is fitted to the precise (driver’s aspect) rear, and the (passenger aspect) left entrance turns into the spare. The correct rear goes to the precise entrance, which fits to the left rear. The left rear strikes to the left entrance.
Scale back pressures
When touring on outback filth roads along with your 4×4 and caravan, drop tyre pressures to round 25psi. The much less stiff, extra versatile tyre carcass will scale back the possibility of tyre punctures. When you shouldn’t tow at greater than 80km/h on filth anyway (because of the diminished grip and due to the injury you are able to do shaking gear round in your caravan), that is particularly related once you’ve dropped tyre pressures as warmth build-up within the tyres will threat a tyre blow out. Keep in mind to re-inflate tyres to beneficial pressures earlier than returning to sealed roads.
 The way to learn a sidewall
Three varieties of dimension descriptions are used on 4X4 and caravan tyres. For instance:
265/65R17 100T
9.50R16LT
32×11.50R15 LT
Learn the placard
A tyre placard is a plate or sticker that, by regulation, have to be fitted to autos and caravans with the tyre sizes designed for the car and the minimal velocity and cargo scores for these tyres. These are thought of the legally appropriate specification tyres on your car. You may normally discover the tyre placard caught on someplace like a door jamb or aperture, gas filler flap or glovebox lid in your car and the compliance plate on your van, normally fitted to both the boot, door entry space or A-frame.
