in WA its no more than 50mm lift INCLUDING tyre lift.
From the NCOP that WA follow:
www.infrastructure.gov...eb2006.pdf from:
www.infrastructure.gov..._ncop.aspx (page 20/71, section 4.10)
Modifications that result in raising the vehicle body greater than 50mm are to be carried out and approved in accordance with Codes LS7 and Code LS8.
LS7 - page 61 - point 1: Design of modifications that result in the vehicle body being raised by more than 50mm from the original "as manufactured" height.
Page 63: Wheels & Tyres - The overall tyre diameter can be increased by up to 26mm (four wheel drive vehicles only). Tyres fitted to commercial vehicles must not be more than 50% wider that the vehicle manufacturer's widest optional tyre.
The wheel track of off-road and four wheel drive vehicles must not be increased by more than 25mm...
LS8 - page 68 - point 1: Design of modifications that result in the vehicle body being raised by more than 50mm from the original "as manufactured" height. which includes points 6. installation of body lift and 7. alternative wheel and tyre specifications with modified axles or suspension.
So in essence.. a 215/75r15 is in fact ILLEGAL to run on a vehicle that has a stock 205/70r15 as its 35.5mm larger - exceeding the maximum allowed increase by 9.5mm, and running a larger tyre in combination with a lift of 50mm or more is also illegal.
Cool huh? =)
