18.5 x 10.5 Low Profile Pro-Speed Medium

Low Profile and Medium Compound: the combination that makes a difference on track

The Low Profile Pro-Speed Medium tyres from Sideways in size 18.5 x 10.5 mm are designed for those who want to maximise performance without sacrificing consistency throughout the race. The low profile reduces the vehicle's height and helps lower the centre of gravity, improving stability in corners. The Medium compound offers the ideal middle ground: enough grip to tackle corners with confidence and the hardness necessary to maintain predictable behaviour throughout the session.

Function and Performance

The Low Profile design is not just aesthetic: by reducing the effective diameter of the tyre, it enhances steering response and minimises body roll in the fastest corners. The Medium compound is a very versatile choice, suitable for both plastic tracks and wooden circuits, where soft rubber tends to pick up dirt too quickly and hard rubber does not reach optimal temperature.

This balance makes them a regular reference for long practice sessions and club championships where consistency matters as much as lap time.

Compatibility and Fitting

They are designed to fit rims between 15.8 and 17.3 mm in width. Before installing them, check the width of your rim with a caliper to ensure they fall within the indicated range. A correct fit ensures that the tyre is perfectly centred and free from lateral tensions that could distort the rolling profile.

As with any competition tyre, we recommend truing them with a truing lathe once mounted, to achieve perfect concentricity and eliminate any diameter variation that could cause vibrations.

Ideal for…

• Club racers looking for a versatile compound for different types of track.
• Tuners wanting to lower their car's centre of gravity without changing the rim.
• Enthusiasts competing in long-duration championships where compound durability is key.
• Slot cars with rims in the range of 15.8 to 17.3 mm that need a real performance option.

Considerations

The Medium compound is not the softest in the Pro-Speed range, so it may require a few initial laps to reach optimal temperature, especially on cold or low-abrasion tracks. If your circuit is very aggressive or the session is short, consider whether a softer compound might better suit your conditions. For long sessions or circuits with less abrasive surfaces, the Medium is usually the most suitable choice.

Frequently Asked Questions

How many units are included in the pack?

The provided information does not specify the number of units per pack. We recommend checking the product sheet in-store or contacting our team to confirm before placing your order.

What type of track is the Medium compound recommended for?

The Medium compound performs well on plastic and wooden tracks with medium abrasiveness. It is a balanced option that delivers consistent performance without accumulating too much dirt or losing grip throughout the race.

Do I need a truing lathe to use them?

It is not strictly necessary, but it is highly recommended if you are looking for maximum performance. Truing ensures that all tyres spin with the same diameter, eliminating vibrations and improving the car's response.

Are they compatible with rims from other brands?

Yes, as long as the rim width is within the range of 15.8 to 17.3 mm indicated by Sideways. The brand of the car or rim is not decisive; what matters is that the measurements fit correctly.

What is the difference between a Low Profile tyre and a standard one?

The Low Profile tyre has a lower sidewall height, resulting in a smaller outer diameter for the same rim. This lowers the car's centre of gravity, improves cornering stability, and reduces body roll, at the cost of less absorption of track irregularities.

Sideways Pro-Speed Medium Low Profile tyres 18.5x10.5 mm are a top choice for slot car competitors seeking consistent grip and stable handling throughout long practice sessions and club championships. Designed to fit rims between 15.8 and 17.3 mm wide, these low-profile tyres lower the car's centre of gravity for improved cornering stability. The medium compound strikes the right balance between traction and durability, performing reliably on both plastic and wooden tracks. A must-consider upgrade for 1/32 slot car tuning and performance preparation.
