Land Transport Rule
Tyres and Wheels Amendment (No 2) 2009
Note: This Rule should be read in conjunction with the consolidated version of Land Transport Rule: Tyres and Wheels 2001, which includes previous Rule amendments.
- 2.1 Clause 2.3 General safety requirements for tyres
- 2.2 Clause 2.6 Spare tyres
- 2.3 Clause 4.6 Functions and powers of the Agency
Land Transport Rule: Tyres and Wheels Amendment (No 2) 2009 amends Land Transport Rule: Tyres and Wheels 2001 (the Rule), which specifies safety requirements and standards for tyres, and the assembly of tyres, wheels, hubs, and axles for vehicles operating on New Zealand roads.
The objectives of this amendment to the Rule are:
- to allow a vehicle inspector to take into account written evidence from a person with current specialist tyre knowledge and experience in assessing the safety of a radial-ply, heavy vehicle tyre with exposed cords in the tread area;
- to reduce the risk of motor vehicle crashes associated with winter ('snow') tyres by requiring that if a vehicle is fitted with those tyres they must be fitted to all road wheels of the vehicle;
- to set new minimum tread depth requirements for winter tyres to ensure that those tyres are effective for their purpose;
- to remove the requirement for the label on a temporary-use spare tyre ('space-saver tyre') to be approved by the NZ Transport Agency (NZTA), which is no longer considered to be necessary and the removal of which would result in a reduction in compliance costs;
- to insert a definition of 'winter tyre'.
The NZTA released a yellow draft of this amendment Rule in February 2009 for public comment on the proposed changes. The NZTA notified about 650 groups and individuals who had registered an interest in the Rule, by letter or email, of the availability of the yellow draft, and copies were sent to key industry and other groups. The yellow draft was made available through the NZTA’s Contact Centre and, together with Questions and Answers, was available on the NZTA’s website.
The availability of the draft amendment Rule was publicised in the metropolitan daily newspapers in Auckland, Hamilton, Wellington, Christchurch and Dunedin and in the New Zealand Gazette. The NZTA received 16 submissions on the draft amendment Rule.
The submissions that were received were taken into account in redrafting the amendment Rule before it was submitted to Cabinet, and then signed by the Minister of Transport.
