The GPM MZA891RW20G is a rubber wide rear radial tire set supplied as 1pr for Mini-Z AWD use. It uses the Shape-c 20 degree profile named in the product title and is intended for scale Mini-Z AWD setups where rear traction tuning is important.
Fitment is listed for Mini-Z AWD platforms and related MR-03 AWD variants referenced in the product group, so these tires install onto compatible Mini-Z rear wheels or wheel assemblies that accept this radial style. The rubber compound is chosen to adjust rear grip characteristics without requiring changes to electronics or driveline parts.
Fit these tires when you want to tune rear-end traction and balance during indoor track sessions or practice runs, and swap back to standard tyres when you need the original handling back.
