NZTA BAN TYRE LETTERS
Yeah, you read that title right. In a new round of in-service-certification (warrant-of-fitness) amendments, the New Zealand Transport Agency (NZTA) has now made the presence of tyre lettering a reason for rejection when undergoing a WOF. The change comes under section 10-1 Tyres and Wheels, which states: “A tyre has had the following information removed or concealed so that the tyre can no longer be identified — manufacturer, brand, model, load rating, speed rating, standards markings ( where applicable) and direction of rotation (where applicable).”
This amendment includes visual examples of tyre lettering obscuring information as reference material for inspectors.
The wording around the use of external wastegates has also been altered to include the current practice of a “plumbed-in system” — which was previously unmentioned — and the only permitted systems, under the standards, were those “that feed gasses into their own muffled exhaust system exiting behind the passenger compartment”.
Definitions have also been tightened around bumper reinforcement bars and bumper fascia with regard to altering structural components, which will affect the interpretation of legalities concerning the likes of front-mount intercoolers.
These changes are set to be effective from 1 November 2018 onwards.
