Overview of the RC18T rear radial

This single rear radial tyre suits the Associated RC18T, listed as part AR899R30G. The rubber radial design includes an internal insert and a 30 degree shoulder profile intended for rear axle applications on scale off-road kits.

The part fits specifically to RC18T rear setups and is sold as 1 pcs. The radial profile with insert supports shape retention under load and offers a stable contact patch for setup and tuning work.

Standard installation applies for rubber tyres with inserts - place the insert into the tyre, seat it evenly on the wheel, trim any excess and balance the assembly for consistent lap times. Small insert or offset changes will tune rear bite and rotation response.

Do these tyres come glued to the insert?

No, the tyre and insert are supplied separate so you can position and glue or leave removable depending on your balancing preferences.

Is this part sold individually?

Yes, the item is sold as a single piece, 1 pcs, suitable for replacing one rear tyre or testing different inserts.

What tuning changes are most effective?

Start by testing insert thickness and lateral offset; small adjustments deliver noticeable changes in rear traction and rotation without swapping compounds.
