Power King tyres are sold for light trucks, SUVs, trailers, and on- and off-road use. Choosing the right one comes down to the vehicle, its load, and how it is driven. This guide explains how to match a Power King tyre to your vehicle, what the sidewall markings mean, and how to care for the tyres. Ranges change, so confirm current models and sizes with the manufacturer or a tyre supplier.
Match the size and load rating
Start with the tyre size, load index, and speed rating on your current tyre or in the owner’s manual. Trucks and trailers carry heavy loads, so the load index matters most. Any replacement must meet or exceed the vehicle requirement, and must be approved for the wheel width.
Read the sidewall markings
The sidewall shows the tyre size, load index, speed rating, and load range, along with the DOT code and manufacture date. Load range markings show the tyre’s capacity at a given pressure, which is important for trailers and heavy-duty trucks. Check the markings before buying, not only the size.
Choose the right type for your use
Highway tyres suit mostly paved roads. All-terrain tyres suit a mix of road and light off-road use. Mud-terrain tyres suit serious off-road work, but they are noisier on the road. Trailer tyres are designed for steady loads and should not be used for driving-axle duties unless approved.
Tyre pressure and load
Keep pressures at the level required for the load. Under-inflation overheats the tyre under heavy loads, and over-inflation reduces grip and wears the centre of the tread. Check pressures when the tyres are cold, before every trip with a heavy load.
Fitting, balance and inspection
Have tyres balanced when they are fitted, and check the wheel nut torque after the first short drive. Inspect the tyres regularly for cuts, bulges, and uneven wear, and check the tread depth. Replace tyres that show sidewall damage, whatever their age.
Tyre age
Check the DOT code to see when the tyre was made. Many manufacturers advise replacing tyres after a set number of years, even if the tread looks good, particularly on trailers, which are often used less and can age without showing wear.
Frequently asked questions
Are Power King tyres good? They can be suitable for the right use. Choose by size, load range, and use rather than by brand alone, and compare current independent test results where available.
Can I use a trailer tyre on a truck? Not unless the tyre is approved for that use. Check the markings and the vehicle specification.
How do I find the right size? Check the tyre size on your current tyre, the owner’s manual, or the trailer data plate, and match the load and speed ratings.
