I've got the S-Line 20's w/ Conti's. Checked tire pressure last night which was in the mid 30's all around. Checked the door pillar which said 42 front and 49 rear so I went ahead and inflated to specs. That's pretty high imo.

That is the recommendation with full load

The label on the door pillar doesn't give you a range.

I too find the PSI specs to be strange. What would be the "best" PSI for all-around comfort, handling and mileage, assuming the load consists of 4 adult passengers? I'm on the stock 18's.

am glad someone is picking up on this!

I have 22" was advised by th 3rd party fitters that I shld have 32 PSI all round.

I could tell that was visually too low so I upped it to 46PSI rears and 42PSI fronts.

My tires state highest PSI is 51 thus I am within range and car feels solid - was 'sliding' round bends at 32 PSI.

I guess in time I would know if PSI is wrong as tire ware would indicate so.

RAD2

Yes, maximum weight capacity.

look in the manual (tire pressure section)

That would be an extreme. Odd to give only PSI recommendations at the extreme and not the average

Look in the manual
