Wheels. 19 inch vs 18 inch

If you run 19s then you have to increase pressures to compensate for the lack of free volume within the tyre carcass.

Yep, I'm running 38F 37R. The dealer always drops it down to 34/33 when it goes in for anything.. too low for 19's IMO.

i'd be running at 42F/38R in a 225/35r19 with just 1 or 2 people on board. Your dealer is insane.

just out of interest, what does it say inside the fuel flap? I'll assume 19" isn't listed but what about for 225/40r18?

Yeah I find anything below 38 too low. Sticker says 39/39. Most of the time it's just me and the 3 kids. Lots of road work going on around here though so I found 40+ a bit harsh.
