Yeah, ad08r's and ao50's in 225/45, and 245/40 for 15s would be the greatest. Maybe some sizes in between too

I'm surprised at how good 225 A050s feel on 10x15" rims. The car sits a bit high but the grip levels are excellent. I've been running them at 22PSI hot and even at those crazy low pressures the turn in is great and there is very little squirm. I think the tyre stretch makes a big difference to sidewall feel.

The drifters are on to something.
I was surprised how much difference in gearing the 225/50 vs a 205/50 made. With my limited/no power, it really hurt speed at the end of the straight.

unfortunately the car really needs a wide tyre and this is the smallest rim a suitable one will go on.

Yeah, no point rocking up on 205s, even with a built NA engine, let alone boost

More boost in the motor than in the tyres.

In F1 they can feed some of the boost through to top up the air tank to drive the pneumatic valves and gearbox etc. They are probably well past 50 PSI though.
