Max tire size on a stock rallye wheel / setup ideas

The problem is that here in Australia the tires can only be different by one size for the car to be legal, so these are probably the best setups I can have.

I think I'll go with the 65 profile just because it's a lot cheaper than the 70. There won't be much difference in height with only 5% between the two sizes.

Thanks for the info guys!

Cheers.
