Low Profile Tyres

Low Profile Ultragrip Tyres: Grip and Precision for Your Slot Car

The tyre is one of the elements that most influences the behaviour of a slot car on the track, and the choice of the right profile and compound makes the difference between running stably or losing traction in every corner. With the reference SRCRN0107, SRC offers a pack of 4 low profile Ultragrip tyres (T45) designed for front, rear, or 4x4 traction cars, thus covering a wide range of setups.

Technical Features

• Pack Contents: 4 low profile Ultragrip tyres (T45)
• Traction Compatibility: 4x2 and 4x4
• Width: 8.60 mm
• Diameter: 17 mm
• Bead: 0.9 mm with applied shrinkage (tolerance ± 0.05 mm)

Function and Performance

The low profile Ultragrip from SRC is designed to provide an optimal contact patch with the track surface, enhancing stability during braking and corner exit. The T45 compound represents a balance between hardness and grip, suitable for both regular running sessions and club racing preparations.

The 0.9 mm bead with applied shrinkage ensures that the tyre sits well on the rim without the need for additional intervention, reducing the risk of displacement during driving. The tolerance of ± 0.05 mm indicates careful dimensional control, important when seeking consistent behaviour at all four contact points of the car.

Mounting and Preparation

Before mounting the tyres, it is advisable to check that the rims are clean and free from adhesive residue or dirt. If you wish to optimise grip from the outset, a light sanding with fine-grit sandpaper can improve diameter uniformity. Since the pack includes 4 units, it is possible to equip the entire car —both front and rear axles— with the same model, ensuring symmetrical behaviour.

Ideal for…

This tyre fits particularly well with all-wheel drive (4x4) setups where grip is required at all four points, although it is also valid for more conventional 4x2 configurations. The 17 mm diameter makes it compatible with rims of the appropriate scale for that size; always check the dimensions of your rim before mounting.

Considerations

Check that the diameter and width of your rims match the tyre specifications (17 mm diameter and 8.60 mm width) before ordering. The indicated tolerance (± 0.05 mm) is indicative and may be affected by storage conditions; keep the tyres away from heat sources and direct light to preserve their properties.

Frequently Asked Questions

How many units are included in the pack?

The SRCRN0107 pack includes 4 low profile Ultragrip tyres (T45), sufficient to equip a complete car on all four axles.

What type of traction are they designed for?

They are indicated for cars with 4x2 and 4x4 traction, covering most common slot configurations.

What does the T45 compound mean?

The T45 refers to the hardness of the tyre compound. A value of 45 represents a balance between grip and durability, suitable for general use and club racing.

Is it necessary to sand the tyres before use?

It is not strictly necessary, but light sanding can improve diameter uniformity and optimise contact with the track from the outset.

What tolerance do the indicated measurements have?

The bead measurements (0.9 mm) have a tolerance of ± 0.05 mm, indicating careful dimensional control and appropriate for competitive use.

What rims are they compatible with?

They are compatible with 17 mm diameter rims that accommodate a tyre width of 8.60 mm. Always check the specifications of your rims before placing an order.
