4 Classic Tyres 20x6 Smooth

Classic Smooth Tyres 20x6: Reliability and Consistency on Every Lap

The tyre is one of the elements that most influences the behaviour of a slot car on the track, and it is often the first to require replacement after several running sessions. This pack includes 4 classic smooth tyres in size 20x6, with reference CXM070, designed to fit directly onto the M026 rim.

Tyre Features

• Size: 20x6 mm
• Profile: smooth, no tread pattern
• Type: classic
• Declared compatibility: M026 rim
• Pack contents: 4 tyres
• Reference: CXM070

Function and Performance

The smooth profile offers the largest possible contact surface with the track, resulting in a uniform footprint and predictable behaviour both on straights and in wide-radius corners. This type of tyre is common in club racing cars where consistency and regularity lap after lap are prioritised over aggressive lateral grip.

With no tread, wear is uniform across the entire contact patch, extending the tyre's lifespan as long as the fitting is correct and the car is well balanced.

Fitting and Preparation

Before fitting the tyres, it is advisable to clean the M026 rim with a dry cloth to remove any silicone, grease, or dust that may compromise the adhesion between the rubber and the rim. Once fitted, it is recommended to slightly true the tyres with a bench sander or similar to ensure perfect concentricity relative to the axle, especially if competing on a track. A well-trued tyre eliminates wobble at high speeds and significantly improves contact with the track.

Check that the size 20x6 corresponds with the available space on your rear axle before installing them, as a few millimetres of difference can affect the ride height and the car's behaviour in corners.

Ideal for…

This pack is designed for enthusiasts looking to replace the tyres on their slot cars with a classic smooth profile option. It is suitable for both recreational use on home tracks and club racing in categories where this type of rubber is permitted. It is also useful for preparers working on multiple cars simultaneously who prefer to have a stock of tyres on hand.

Common Mistakes

• Not checking rim compatibility: these tyres are designed for the M026 rim; fitting a tyre on a rim of different diameter or width can lead to improper fitting and loss of control.
• Omitting truing: even new tyres may have small factory irregularities. Truing before the first racing session improves the final outcome.
• Applying lubricant in the contact area between rim and tyre: reduces grip and may cause the tyre to spin on the rim under load.

Frequently Asked Questions

How many tyres are included in the pack?

The CXM070 pack includes 4 classic smooth tyres in size 20x6.

Which rim are these tyres compatible with?

According to the manufacturer's information, they are designed to fit the M026 rim.

Is it necessary to true the tyres before use?

It is not strictly mandatory for recreational use, but it is highly recommended if competing. Truing ensures concentricity and improves contact with the track, reducing vibrations at high speeds.

Can they be used on plastic and wooden tracks?

The smooth profile works on various surfaces. The specific behaviour will depend on the hardness of the rubber and the track conditions, factors that the manufacturer does not specify in the available information.

How long do these types of tyres last?

The lifespan depends on the type of track, motor power, and frequency of use. A smooth profile tends to wear evenly, making it easier to detect when it is time to replace them.
