Thread: 275 65 18

Hi Kerryr,
First off do you have a spare wheel carrier?
If so yes either will fit.
If no then the 265 / 65 R18 will fit under the car only if deflated, it's approx 800mm in diameter.
The 275 / 65 R18 will most probably not fit underneath though, it's approx 815mm in diameter.

Thanks Rich
Yes I have rear wheel carrier and looks like the 275 65s are the go,hope to have ready in next couple of weeks.

I know it has been dne many times, but what is legal in NSW about changes in tyre width and diameter?

Still currently + or - 15mm "Rolling Diameter" only legal max.
Hopefully NSW will follow the other states where up to + 50mm is legal.

Believe it or not Rich NSW have actually adopted the National code as well, which they allow to run in parallel with their own State code, so it is possible to fit up to 50 mm larger tyres providing you get it engineered and then noted on your ego papers at the RTA. Then you must keep the rego papers in the vehicle all the time as proof of the modification in case you get stopped by the Police or RTA.

Actually I thought that was the case for yonks, as long as an engineer certificate was done on the vehicle. Do the other states require this certificate?

In Victoria we do not need to carry certification.

You can suspension lift the car 50mm & fit 50mm dia bigger tyres so 75mm of total lift.

Yep it has, but the mods must not exceed the National code so the RTA told me. Most other States don't require a Engineers cert now like NSW till does. ...
