My placard is not much different to yours. FYI I've attached it and highlighted the section I was reading from.

I don't mind being out a few k's on my speedo but not double that amount. I'm leaning to sticking with 45 profile tyres if the effects are as severe as you estimate.

Bridgestone has offered to give me the RE050A's for $315 which will reduce to $236 per tyre after the promo. Jax have the Michelin SP3 45's for $291 per tyre with a $100 fuel card promo so that cuts it to $266 per tyre, but I haven't fully shopped around for those yet and I may find them cheaper. I wouldn't mind trying those out as I've read quite a few good reports about them.
