larger rolling diameter legality Perth?

[lefty]

looking at tyre options for the 15x6" Audis. what is the largest tyre you can go while staying legal?

Legal is +15mm rolling diameter.

215/70-15 is 18mm increase in diameter over 215/60-16

I'd personally choose 205/75r15 for the extra height verse width...

thanks, that pretty much leaves me with only 205/70/r15

nice but that's +24.1mm which would be illegal?

I got mine 217 75 15 engineer over 215 60 16

205/75/15 is what I've got, they don't look any bigger than the stock 205/70/15. Good size and don't scrub on the sf

Im getting a set of 225/75R15 Nexen ATs. Will be slightly smaller than my 225/70R16s and fit an SG. Not quite legal but will make the speedo read correctly.
