R0 15x8 Wheels — the starting point for a balanced rear end
The R0 15x8 wheels (CXM020) come in a pack of 2 units and are designed as a direct replacement or as a tuning part for those looking to adjust the rolling diameter, offset, and wheel behaviour on track. A well-chosen wheel is the foundation on which the tyre works correctly: if the wheel vibrates, is out of true, or does not fit well with the tyre, everything else becomes irrelevant.
Function and features
- Dimensions: 15 mm diameter × 8 mm width (standard format for competition and tuning slot cars).
- Pack of 2 units, sufficient to equip the rear axle of a car.
- Reference CXM020, easy to locate for replacement.
- Design compatible with mounting tyres of equivalent section, facilitating adhesion and centring.
Assembly and preparation
Before mounting the tyre, it is advisable to check that the wheel spins without eccentricity on the axle. A light pass with fine sandpaper on the lathe or with a Dremel can eliminate tenths of a millimetre that make a difference on track. When gluing the tyre, apply the adhesive in a thin and even layer to avoid imbalances. Allow to cure for the time indicated by the adhesive before turning.
Compatibility and applications
The 15x8 wheels are a common format for 1/32 scale cars for the rear axle, especially in setups aimed at club racing or federated competition. Their use is frequent when combined with silicone or urethane tyres of 8 mm section. Always check that the hub diameter fits your axle before purchasing.
Common mistakes
- Mounting the tyre without first checking the centring of the wheel on the axle.
- Applying too much adhesive, which creates an imbalance that is clearly noticeable at high speed.
- Not checking that the width of the wheel is compatible with the chosen tyre: a tyre that is too narrow or too wide relative to the wheel does not seat properly and loses performance.
Frequently asked questions
What does the R0 designation mean for these wheels?
The R0 nomenclature refers to the type or profile of the wheel within the manufacturer's catalogue. It indicates a specific geometry of hub and outer profile. Consult the manufacturer's documentation to confirm which cars and axles accept this specific type.
Are the dimensions 15x8 diameter × width or the other way around?
In the usual slot nomenclature, the first value (15) corresponds to the outer diameter of the wheel in millimetres and the second (8) to the width. Thus, a 15x8 wheel has a diameter of 15 mm and a width of 8 mm.
What tyres do these wheels combine with?
Generally, with 8 mm section tyres designed for 15 mm diameter wheels. The most common materials in competition are silicone and urethane. Always check the tyre measurements before purchasing to ensure a proper fit.
Can I use them on the front axle?
It depends on the car. In many competition models, the front wheel is narrower or of a smaller diameter. Check your chassis specifications before mounting these wheels in any position other than that indicated by the car manufacturer.
How many wheels are included in the pack?
The pack contains 2 wheels, just enough to equip the rear axle of a slot car.
The R0 15x8 slot car wheels (ref. CXM020) come in a pack of 2 units, designed for 1/32 scale slot cars. With a 15 mm diameter and 8 mm width, these replacement rims are a standard choice for rear axle setups in club racing and competitive slot car preparation. Compatible with silicone and urethane tyres of matching section, they provide the stable base needed for precise tyre mounting, centring and gluing.
