Damn where did u get that tyre placard??? Mine only says 16. If i had that tyre placard i would hav saved $100's on defects! Just to reconfirm, every dumb coppa in sydney says 1inch wider, 1inch higher than wat it says on the tyre placard. I suppose u could try an argue with em but last time i was threatened with being arrested so i stay quiet now. lol
