Section XIX-D.
The following requirements must be met for your vehicle to be allowed in competition. All vehicles are subject to inspection at any time before, during, or after the event for legality. This section goes over the tire types allowed, wheel specifications, and requirements for RC drifting competition.
1. No rubber racing tires, no E-taped tires, and no unidentifiable tires (i.e. cut ABS/PVC/PE) are allowed during qualifying and/or main bracket competition.
2. All competition chassis must run drift tires mounted securely on wheels that are made and designed for 1/10-scale touring cars. Drivers are encouraged to glue their tires to the wheels with CA glue.
3. No “plus” sizing or use of “mini” scale wheels/tires; these will not be legal for qualifying and competition. The only exception is during open practice and/or concourse competition.
4. Unless a particular tire is specified by the event, drivers must run any identifiable, branded, “plastic-type” drift tire in competition. Tires must be easily identifiable for tech inspection. These include (alphabetical order by brand):
a. HPI Racing
1) #4406 T-Drift Tire 26mm
2) #4421 Advan Neova AD07 T-Drift Tire 26mm
3) #4422 Proxes R1R T-Drift Tire 26mm
4) #4423 Potenza RE-01R T-Drift Tire 26mm
5) #4424 Direzza Sport Z1 T-Drift Tire 26mm
6) #4425 Falken Azenis RT615 T-Drift Tire 26mm
b. Take-Off
1) #RPD RP-D Tires
c. Tamiya
1) #54020 Super Driftech Tire 24mm
d. Yokomo
1) #ZR-DR01 Zero-One ‘R’ double ring
2) #ZR-DR02 Zero-Two ‘R’ single ring
3) #ZR-DR03 Zero-One ‘R’ low-profile double ring
5. Tires must have at least 50% of the sidewall intact (approx. 2mm). Tires worn below this limit will be okay for practice, but may be flagged as “illegal” for qualifying and competition, due to the fact that they may not be easily identifiable.
6. If you use another drift tire than what is listed, please bring it to the attention of the event staff BEFORE the actual competition begins. The legality of the tire is up to the event staffs’ discretion unless clearly identified as ILLEGAL in these rules.
7. Anyone found or suspected of using a non-approved or unidentifiable drift tire may be asked to change to legal, identifiable tires, or will be subject to disqualification.
8. If illegal tires were used during qualifying, all qualifying points for the driver in question will be removed. If illegal tires were used during a tandem round, the driver in question will be disqualified.
9. Some events or competitions may have modifications, exceptions, or additions to the rules above.
