Hi, glad I found this forum so I can sound like an idiot semi-anonymously rather than in person to the local engineer.
I have a VW Touareg that was certed when it came into NZ in 2017, a couple of weeks before it was issued rego plates. The cert was only for adjustable suspension, and specifies "OE F&R" for rims, with no specific dimensions. No mention is made of tyre size.
Does this limit wheel options to the stock wheel for that specific chassis number (18x8 ET57) or can another OEM option for the platform be used without re-cert? For example, 19x9 ET60 and 21x10 ET50 were OEM fitment for other Touareg models that same year. I'd actually prefer to run 20s, which weren't offered on the Touareg but were on other vehicles built on the VW PL71 platform, namely the Audi Q7 and Porsche Cayenne.
Or am I over-thinking this and something like a 20x9 is acceptable anyway, as long as it's a reputable brand etc? 20x9 ET35 are readily available, and I'd be happy running them as long as it clears body, brake, steering and suspension components. I want to further improve handling and grip, looks aren't a consideration.
I'm pretty sure your answer is going to be "you'll need a re-cert either way" but hope springs eternal. If I'm going to need a re-cert then at least I can investigate a wider range of sizes and offsets.
Bonus question: A whole lot of 22in tyres seem to carry a 102 load rating, while stock for my specific vehicle is 109. Since a 102 is still well above a quarter of the GVM can tyres with this rating be used?
Many thanks in advance.
