Professional Tyre Repair Solutions by Maruni Japan

A proper tyre repair is about more than simply sealing a puncture. Choosing the correct repair method helps ensure safety, durability, and long-term performance.

Every tyre damage is different. A small nail puncture in the tread requires a different repair method than a larger injury, a sidewall cut, or damage to an inner tube.

At Setia Tyre Repair Product (M) Sdn. Bhd., we are proud to supply genuine Maruni Japan tyre repair materials, trusted by tyre shops and automotive workshops worldwide for their quality and reliability.

This guide explains the most common Maruni tyre repair products and when each one should be used.

Why Choosing the Correct Repair Material Matters

Using the wrong repair product may result in:

❌ Air leakage

❌ Poor adhesion

❌ Premature repair failure

❌ Reduced tyre safety

Professional workshops select the repair material based on:

• Tyre construction
• Damage location
• Size of puncture
• Passenger or commercial vehicle
• Tubeless or tube-type tyre

1. MR Series Tyre Patch

Best for:

Small to medium punctures on radial passenger car tyres.

The MR Series is one of the most commonly used repair patches in tyre shops.

Its flexible construction allows it to conform to the tyre's inner liner while providing a strong, permanent repair when used with the correct vulcanizing cement.

Suitable for:

✔ Passenger cars

✔ SUVs

✔ Light commercial vehicles

✔ Radial tyres

Ideal when repairing nail punctures from the inside of the tyre.

2. MB Series Tyre Patch

Best for:

Medium to larger tyre injuries requiring a stronger repair patch.

Compared with the MR Series, the MB Series offers additional reinforcement and is suitable for more demanding repair work.

Recommended for:

✔ Larger punctures

✔ Commercial vehicle tyres

✔ Workshop professional repairs

3. MU Series Tyre Patch

Best for:

Heavy-duty radial tyre repairs.

The MU Series is designed for larger commercial tyres that experience higher loads and operating pressures.

Suitable for:

✔ Trucks

✔ Lorries

✔ Buses

✔ Industrial vehicle tyres

4. Plug Patch Series

Best for:

Punctures that pass completely through the tyre.

The Plug Patch combines two repair methods into one product:

• The plug seals the injury channel.
• The patch repairs and reinforces the inner liner.

This provides a more complete repair than using a plug or patch alone.

Common applications:

✔ Passenger car tyres

✔ SUV tyres

✔ Light truck tyres

Recommended for straight tread punctures caused by nails or screws.

5. Power Valkaseal Repair Strings

Best for:

Quick external puncture repairs.

Power Valkaseal repair strings are commonly used when immediate repair is required.

Suitable for:

✔ Temporary roadside repairs

✔ Workshop emergency service

✔ Tubeless tyres

Many workshops also use repair strings before recommending a permanent internal repair.

6. Tube Patch Series

Best for:

Inner tube repairs.

Designed specifically for repairing motorcycle, bicycle, agricultural and tube-type tyres.

Suitable for:

✔ Motorcycle tubes

✔ Bicycle tubes

✔ Wheelbarrow tubes

✔ Agricultural equipment

7. Stem Series

Best for:

Valve stem repairs and replacement applications.

Maintaining a good valve stem helps prevent slow air leaks and ensures reliable tyre inflation.

Repair Chemicals Every Workshop Should Have

It provides excellent bonding strength between the repair patch and tyre casing, making it suitable for professional tyre repairs.

Recommended for:

✔ Plug Patches
