GPM Team Associated RC18T Rear Radial Tyre Standard Rubber 40 degree Insert AR899R40G - Upgrade Part  [AR899R40G]

Rear radial tyre for RC18T

This rear radial tyre is produced as a replacement for Team Associated RC18T rear fitments, identified by model AR899R40G. It uses a standard rubber compound together with a 40 degree insert to reproduce the correct tread profile and sidewall stiffness for RC18T rear assemblies.

Fitting to compatible RC18T wheels follows a simple routine: remove the old tyre from the rim, seat the new tyre over the bead, place the insert to set the desired sidewall firmness, then trim or tuck the bead to suit the wheel. Basic tyre tools are all that is required for a neat installation.

Used as a tuning piece, the 40 degree insert affects how the tyre maintains shape under lateral and drive loads, influencing rear traction and steering balance. Combine insert choice with compound and suspension tuning when optimising rear behaviour on carpet or firm surfaces.
