I always look at the tyre wall to see max pressure and pump moderately..

[Odessus]

I pump my 18" 250kpa front 280kpa rear (hot).

[Martin]

I pump at 240kpa front & rear. Should I go higher?

Are you on a staggered setup?

What car? What tyre section? Front or rear? What tyre model?

You should mostly stick with manufacturer recommendation found on door or fuel flap.

I am a smart alec so I do it my way. Please don't follow.

SLK R172 non OEM tyre size.

Front: 245/40R18 230 kPa cold. Michelin PSS

Rear: 255/35R18 260 kPa cold. CSC5P

Can share why you mix and match different tyres for front and back? I've seen some cars doing the same as well...
