Tire compound comparison

Tire type characteristics

When looking for racing tires, touring (GT) or rally tires often provide strong grip on smooth surfaces such as Roboracer tracks.

We used Stradale Mega Soft tires, which performed well both on smooth floors (auditorium or marble) and on surfaces with rugs or mats.

  • The softer the compound (Mega Soft), the stronger the grip but the faster the wear.
  • The harder the compound (Firm), the slower the wear but the lower the grip.

Therefore, Firm tires are better for asphalt-like conditions, while Mega Soft tires are better for smooth indoor surfaces such as auditorium or marble floors.

Factors that affect grip

Grip depends not only on tire type but also on temperature and humidity.

  • MEGA SOFT: below 0℃ or below 20℃
  • SUPER SOFT: 15℃ to below 25℃
  • SOFT: 20℃ to below 35℃
  • MEDIUM: 30℃ to below 45℃, or ultra-high-grip surfaces
  • FIRM: high-temperature or ultra-high-grip surfaces

In general, higher humidity increases grip and reduces slipping, while dry conditions reduce grip and increase slipping.

Wrap-up

Tire choice depends heavily on surface and temperature/humidity. Softer compounds work best on smooth surfaces, while harder compounds are more suitable for hot or rough conditions. Choose the compound based on the actual environment to achieve stable performance.
