GT-90 Rear Tyre 1/24 Shore 22. Dimensions 27x14

BRM GT-90 Rear Tyre 1/24 Shore 22: Soft grip for 1/24 scale

Within the BRM spare parts catalogue for 1/24 scale, the GT-90 series tyres stand out among enthusiasts seeking a true balance between traction and durability. This rear model, with reference BRM-S306E, comes with a Shore hardness of 22 — a compound clearly aimed at grip — and measures 27x14 mm, placing it within the usual range for rear axles of GT cars in this scale.

Function and Performance

The Shore value is the key data point when choosing a tyre in the 1/24 slot car world. A Shore 22 corresponds to a soft compound, which translates to greater deformation under load and, consequently, a larger contact patch with the track. The practical result is improved traction from corner exit and a more direct throttle response on straights.

• Shore hardness 22: soft compound, ideal for wooden or plastic surfaces with good base grip.
• Measurements 27x14 mm: diameter and width tailored for rear axles of BRM GT cars in 1/24 scale.
• Rear axle mounting: rear position, where traction and stability are paramount.

Compatibility and Mounting

This tyre is specifically designed for BRM 1/24 scale models that use the rim corresponding to the 27x14 measurements. Before mounting, it is advisable to check that your car's rear rim accepts that width and diameter, as a difference of tenths can affect centring and track behaviour.

For correct mounting and optimal performance, it is recommended to:

1. Ensure the rim is clean and free of previous rubber residue.
2. Mount the tyre without forcing it to avoid deforming the sidewall.
3. Lightly turn if a uniform rolling diameter and perfectly symmetrical grip are desired.
4. Clean the track and the tyre before the first session to activate the compound.

Common Mistakes

• Mixing hardness on the same axle: installing a Shore 22 tyre alongside a harder one on the rear axle creates traction imbalance. Always use the same compound on both rear wheels.
• Ignoring uneven wear: on tracks with asymmetric corners, the inner tyre wears out faster. Check periodically and rotate if possible.
• Forcing mounting on incompatible rims: a 27x14 tyre on a rim of different measurements may come off under load or cause vibrations.

Ideal for…

This tyre fits particularly well in:

• Club competition in 1/24 scale where the use of soft compounds is allowed.
• Intensive testing sessions where traction is prioritised over tyre longevity.
• Setups aiming to maximise the performance of a powerful motor, needing more grip on the rear axle to avoid wasting torque.

Frequently Asked Questions

What does Shore 22 mean in a slot tyre?

Shore is the scale that measures the hardness of the compound. A lower number indicates a softer tyre. A Shore 22 is a fairly soft compound, offering more grip but also greater wear compared to higher Shore compounds.

Can I use this tyre on the front axle?

This tyre is designed for the rear axle. The 27x14 measurements correspond to the rear position on BRM GT cars in 1/24 scale. For the front axle, consult the specific BRM references for that mounting.

Do I need to turn the tyre before using it?

It is not mandatory, but turning the tyre ensures a perfectly uniform rolling diameter and improves stability. For competition, it is highly recommended.

Which BRM rims is this tyre compatible with?

The BRM-S306E tyre is sized for rear rims of 14 mm width in 1/24 scale. Check the BRM rim catalogue to identify the rim reference corresponding to your specific model.
