How do I choose a 4X4 tyre?

To give you a head-start, 4WD tyres are broken down into three main categories.

1. All Terrain (A/T) tyres.
2. Highway Terrain (H/T) tyres.
3. Mud Terrain (M/T) tyres.
4. Light Truck (LT) rated tyres.
5. Speed and Load Ratings.
6. Getting the right size.

What is the most common 4x4 tyre size?

The short story is that the top spots now all filled with either 17 or 18-inch sizes. This change has come at the expense of the 16 and 19-inch sizes managed to make it into the top five last year. The most popular 4×4/SUV tyre size remains 235/60 R18, which occupies 7 per cent of the segment.

Are wider tyres better 4x4?

Better traction

The bigger the tyre, the more rubber is in contact with the ground. This results in greater traction, as well as greater flotation. This is why vehicles with taller tyres perform well on the beach. More surface area touching the sand means you have less chance of sinking!

How are 4x4 tyres measured?

Calculating Tyre Diameter

To get the full diameter you need to add the rim size. In the example, this is 16″ (406.4mm). So the total tyre diameter is 213.75mm x 2 (sidewall x 2) + 406.4mm (rim size) = 833.9mm. Now when talking tyre diameter, most people & experts talk in inches – which = 32.83 inches.

Can you run different size tires on a 4x4?

Having different sizes on some four wheel and all wheel drive vehicles can actually do damage to the vehicle. Since tires vary from brand to brand, and even from model to model, damage can even occur with tires of the same size if they have a large enough difference in circumference.

Choosing bigger tyres for your 4x4 benefits & issues off-road, 4 Wheeling Quick tip

Do 4 wheel drive tires have to match?

Drivers with an AWD vehicle should refer to their owner's manual for specific guidance on tire replacement. It's always best to use four tires from the same brand—and the same model—on a vehicle. Unless specified by the automaker, tires should be the same size and have the same speed rating and load index.

Do you have to replace all 4 tyres on a 4WD?

For all-wheel-drive (AWD) cars, it is recommended that all four tires be replaced at the same time. This is because in these cars, the computer and differential work simultaneously to supply torque to each wheel, ensuring maximum control.

How do I choose tyre size?

Your vehicle manufacturer will have written the recommended tyre size in your vehicle's owner manual. This manual should have all the specifications you require to make an informed tyre decision. Tyre size information can also be found on the tyre placard, often inside the drivers door jamb.

What does the R mean in tire size?

“R” stands for the construction method of the tire indicating the tire is a radial tire. The following two numbers (16) indicate the diameter of the wheel rim in inches. The next two or three numbers (94) indicate the load index of the tire. In the example, 94 means the tire can carry 670kg.

What does 32 inch tyre mean?

The first number is your overall diameter of the tire. In this example the tire diameter or "height" is 33 inches tall. The second number represents the width of the tire. In most cases with inch measurement tires the width will have a . 50 decimal after the initial number.

Why are skinny tires better in mud?

The benefits of a narrower tyre are well known in muddy conditions, where a thinner tyre is more likely to cut through surface mud and find firmer ground below.

Do wider tyres use more fuel?

For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.

Are low profile tires good for off-road?

Low-profile tires have stiff tread, which means less contact patch area on uneven surfaces. So, such tires are only for on-road use, and off-road they will be useless. Besides, rocky bumpy roads need more sidewall flexibility, which these tires lack.

Are 17 or 18 inch wheels better?

The Quick Answer

Smaller 18″ alloys will have tires with a lower profile compared to the smaller 17″ alloys. The benefits of the 18″ alloys are that they result in sharper handling and look more aesthetically pleasing, however, the 17″ alloys are more comfortable, quieter and cheaper in comparison.

Are 17 or 16 inch wheels better?

The Quick Answer

Larger 17″ alloy wheels will have give the car sportier handling by improving cornering and stability compared to 16″ wheels. However, 16″ wheels are cheaper and produce less road noise, have better fuel economy and feel more comfortable compared to 17″ wheels.

Are bigger tyres better?

Bigger Wheels = Bigger Bills

Overall, bigger tires and wheels are better for increasing your vehicle's traction.

What does Z mean on a tire?

Some manufacturers will insert a “Z” in the middle of the tire size description (right after the aspect ratio) when the tire is rated at “W” or “Y.” And if a tire is rated in excess of 186 mph (300 kph), manufacturer's usually will list a “Z” within the size description, per industry standards.

What does P mean on a tire?

P identifies your tire as a Passenger Tire. The P stands for PMetric. If your tire size starts with LT rather than a P than it identifies the tire as a Light Truck tire. 225 identifies the tire section width, which is the measurement of the tire from sidewall to sidewall in millimeters.

What do the 3 numbers on a tire mean?

B: TIRE WIDTH The three-digit number following the letter is the tire's width (from side to side, looking at the tire head on) in millimeters. This may also be referred to as the section width. C: ASPECT RATIO The forward slash separates the tire width number from the two-digit aspect ratio.

Can you change just one tyre on a 4x4?

The answer is ideally, yes. Replacing just the one tyre without changing the tyre on the opposite side of the axle at the same time may cause an imbalance to the vehicle – potentially leading to wheel misalignment and excessive tyre wear.

Which tires wear faster on a 4x4?

A 4×4 or four wheel drive (4WD) vehicle powers all four tires equally, so the wear would be determined by forces other than acceleration. This means that front tires, used for steering and braking, would wear faster than rear tires on a 4×4 vehicle.

Can you replace 2 tyres on a 4x4?

What about four-wheel drive (4x4) vehicles? With four-wheel drive vehicles, you may need to replace all four tyres when one gets worn out or has a puncture. This is because 4x4 systems rely on all four tyres when operating.

Can you mix tires on a 4x4?

You should not mix tires in any way on an AWD (all-wheel drive) or 4WD (four-wheel drive) vehicle. If you drive a 4WD or AWD, your tires should match in tread depth, brand, model and size. Mixing tires in any way on these types of vehicles can cause wear and/or damage to the vehicle's drive train.

Should all 4 tires be the same PSI?

It is not true that all 4 of your car's tires should have the same tire pressure. However, all the tires you buy for the same vehicle will require the same tire pressure, regardless of the tire manufacturer – the PSI specified in the car's owner's manual.

Can I buy 2 tires instead of 4?

If two of your tires wear out faster, it may only be necessary to replace those two instead of replacing all four. If you do, it's important to have the two new tires installed on the back and the partially worn tires moved to the front – even on front-wheel-drive vehicles.
