This is an RC-scale replacement set of rubber radial tires in Shape B with a 15 degree profile, produced for KYOSHO Mini-Z AWD use by GPM (MZA890F/R15G). The pair is intended for Mini-Z AWD platforms, offering a straightforward tire option when adjusting front-to-rear grip balance on small-scale tracks.
Constructed in a standard rubber compound, these tires provide predictable contact feedback for tuning steering response and mid-corner traction without altering chassis geometry. The Shape B radial profile and the 15 degree specification refer to the tire shaping used to influence slip angle and bite on typical Mini-Z track surfaces.
Installation is direct: remove the worn tires from the stock wheels and mount this pair in their place, checking seating and even contact across the tread. Use routine tyre maintenance practices such as cleaning before runs and inspecting for wear; avoid solvents that could degrade rubber.
Sold as 1 pr, the set is suitable for hobbyists working on tight indoor circuits where incremental changes to rubber grip and steering feel are the main tuning levers.
