Tires and Running Gear — The Only Contact Point for Riding Safety

Tires are the only part of a dirt bike that contacts the ground, directly determining riding safety, handling, and comfort. Industry data shows that over 30% of preventable dirt bike engine failures are related to poor intake system maintenance, while tire‑related faults are among the leading causes of riding accidents. Below is a detailed guide to tire and running gear maintenance.

1. Tire Pressure — Adjust Flexibly According to Terrain

Dirt bike tire pressure is far from trivial — it is fundamental to dynamic handling and mechanical harmony. Properly calibrated pressure enhances traction, suspension cooperation, tire life, and handling sharpness. Recommended pressure ranges for different riding scenarios:

When riding in mountainous or high‑altitude areas, adjust tire pressure appropriately based on local conditions — tuning pressure is one of the best performance upgrades you can make in just a few minutes.

Checking method and tips:

• Use a low‑pressure gauge with tires cold

• Measure indoors for more accurate readings

• Compare with the owner‘s manual recommendations

• If the bike will be parked for a long time, lift the wheels off the ground or rotate the tires periodically to avoid flat spots

2. Tread Depth — Direct Expression of Grip

Tread depth greatly affects the riding experience. Deeper tread provides better grip and handling; shallow tread means reduced traction.

Checking tread depth:

• Use a tread depth gauge or measure at several points across the tire

• 1.6 mm (2/32″) is the legal minimum safety limit

• Use a coin — if the top of a design is fully exposed, the tire must be replaced

Also carefully inspect sidewalls for cuts, bulges, or cracks, and the tread for embedded nails or stones. If a dirt bike tire shows obvious cuts, bulges, or cracks, repair or replace it before the next ride.

3. Spokes and Rims — The Overlooked Foundation of Stability

Spoke tension and rim trueness are critical for safe riding, especially for dirt bikes that repeatedly absorb impacts on rough terrain. Loose spokes affect wheel stability and can, in severe cases, cause rim deformation or wheel failure.

Spoke inspection and adjustment:

1. Run your fingers over all spokes to feel for even tension and ensure none are loose

2. If a spoke is loose, tighten it gently with a small adjustable wrench (do not over‑tighten)

3. Check the rim for dents or warping — rim trueness directly affects straight‑line stability and tire sealing

Perform a full wheel inspection after every off‑road ride and every 1,000 km. Dirt bike manufacturers recommend lubricating swingarm bearings, steering head bearings, and wheel bearings once or twice a year to prevent them from seizing.

4. Inner Tubes and Puncture Prevention

For tube‑type tires, inner tube maintenance is equally important:

• Whenever you replace a tire, inspect and replace the inner tube as well (rubber ages)

• Before installing a new tube, check the inside of the tire for any sharp objects such as nails or glass

• For extreme rock sections, consider foam inserts or a Tubliss tubeless system for puncture protection, but professional installation is recommended
