Associated RC18T Rear Narrow Radial Tires with 30g Insert by GPM AR893R30G/GPM  [AR893R30G/GPM]

Rear narrow radial tire for RC18T

This tyre set is an RC-scale replacement designed for the Associated RC18T rear axle, supplied as one pair with a 30g insert. The tyre uses a narrow radial profile molded in rubber and is intended for fine-tuning rear traction and handling on short-course 1/18 style setups.

Fit and installation:

• Confirm wheel compatibility with Associated RC18T rear rims before mounting.
• Slide the 30g insert into the tyre prior to seating on the rim to ensure even fit and balance.
• Seat the tyre fully on the wheel, check for smooth rotation, and trim excess bead if needed for clearance.

Tuning role and handling notes:

• The included 30g insert increases rear-end stability and mid-speed traction versus a tyre without insert, helping to tame oversteer on loose or mixed-surfaces.
• Narrow radial profile encourages more predictable turn-in and can be used when a more responsive rear feel is desired.
• Use these tyres as part of stepwise setup changes, altering only one variable at a time to evaluate effect on lap times or handling.

Care and lifespan:

• Inspect tread and sidewalls for cuts or deformities before each run.
• Clean off debris after use and allow tyres to cool before storage.
• Replace inserts if they compress unevenly or show damage.
