20x11 ProSpeed hard tyres

ProSpeed Hard 20x11: firmness and consistency lap after lap

The ProSpeed Hard 20x11 tyres from Sloting Plus (ref. SWPS1HW) are the natural choice when stability and durability are prioritised over maximum grip. The hard compound provides a firm contact patch that keeps the car's behaviour predictable during long sessions, reducing lap time variation and premature wear that penalises softer compounds.

Main features

• Size: 20x11 mm, suitable for rear wheels in standard 1/32 slot setups.
• Compound: Hard, designed to maximise tyre lifespan and provide a firm and controllable rear end.
• Profile: Designed to offer a uniform tread that enhances grip consistency across different track types.
• Manufacturer: Sloting Plus, a brand specialised in spare parts and preparation tools for slot racing.

Function and performance

In slot racing, the choice of tyre compound is one of the most influential preparation decisions. A hard tyre does not provide the instant grip of ultra-soft compounds, but in return offers several clear advantages:

• Greater consistency of lap times throughout a session, with no noticeable degradation.
• Firmer rear end, reducing oversteer in chicanes and fast corners.
• Ideal for tracks with rough or abrasive surfaces, where a soft compound wears out quickly.
• Less stickiness, facilitating clean starts without abrupt reactions when applying power.

Compatibility and mounting

The 20x11 size fits a wide range of standard 1/32 slot rims. Before mounting, it is advisable to check the inner diameter of the tyre against the outer diameter of the rim to ensure a proper fit. The recommended mounting procedure follows the usual practice: centred on the preparation lathe and, if optimal contact is desired, a fine sanding to equalise the contact surface.

Sloting Plus, as a manufacturer specialised in spare parts and preparation tools, designs these tyres to integrate seamlessly into the regular tuning routines of any preparer.

Ideal for…

• Club competitors seeking consistent lap times in long races or endurance leagues.
• Preparers working with abrasive or poorly treated track surfaces.
• Enthusiasts who prefer a manageable and predictable car over one with extreme grip but difficult handling.
• Setups in high-power cars, where a soft compound would be too reactive.

Considerations

The hard compound is not the optimal choice for very smooth tracks or in conditions where maximum grip is crucial. In those cases, medium or soft compounds from the same ProSpeed line may be more suitable. The correct choice always depends on the type of track, the car, and the driving style.

Frequently asked questions

How many units are included in the package?

The manufacturer does not specify the exact number of units per blister in reference SWPS1HW. We recommend checking the product description in-store or contacting our team to confirm before placing your order.

What scale are these tyres intended for?

The 20x11 mm size is common in rear setups of 1/32 slot cars, although final compatibility always depends on the diameter of the rim used.

Do I need to turn the tyres before using them?

It is not strictly necessary, but it is advisable if you are looking for maximum performance. A light sanding on the preparation lathe ensures that the entire tread contacts the track evenly from the first lap.

What is the difference between the hard and soft compounds in the ProSpeed range?

The hard compound offers greater durability and a firmer, more predictable behaviour, while the soft provides more initial grip but wears out faster. The choice depends on the type of track and competition strategy.

Are they compatible with rims from other brands?

Generally yes, as long as the inner diameter of the tyre matches the outer diameter of the rim. The 20x11 size is standard in the industry, but it is advisable to verify the fit in each specific case.
