Default Tire pressure -- door or manual?

What do you set your tire pressure to?
The sticker on my door says 50 psi (2015 Q7 TDI Premium Plus)
But the manual says 35 front/35 rear (normal), and 44 front/49 rear (full load conditions).

Which do you use? I suspect the door column is more accurate, but these are rather different numbers.

(And while I'm talking about tires, I just bought winter tires for next year, downsizing to 255/55 r18's. I don't even have the right size rims yet, but now is a good time of year to get cheaper snow tires.

Defer to the Owner's Manual. The B pillar label shows MAX LOAD only on cars sent to the USA.

35-35 will yield a cushy ride but it will wear out tires much more quickly. On our 2011 on 20” wheels I always ran 44-44 unless heavily loaded or towing. Then I ran 44-49.
We always got great tire life and personally I prefer the crisper feel. The vehicle feels much more agile. I’m running 44-44 on our new to us 2015 on 19” wheels too for the same reasons.

Timely thread! I was just going to ask the same question. The dealer just deflated my tires to the specs in the manual and I was severely annoyed.

+1 here. I tried to split the difference (38-38) and I lost MPG noticeably. 20"
I run 44-44 and back to getting 640 on a tank, running on fumes (straight highway with just a p.p. break {pisses my wife off]) But she's asleep for 500 miles so what is she complaining about...

yup. 640 miles is about our limit on ours too. Thatís Birmingham to DFW. We have grandsons in Keller and make the run frequently.

You're coming in pretty well next door to me in over in Coppell.
I don't even leave Texas and putting 625 miles in on one leg of my circuit.

I'm running 55psi, but I threw the manual out when I put 17in tires on it, my valve stems and tires are rated to like 95psi so I'm no wear near max.. I cant remember last time I ran stockish tire setup so I've always just kinda winged it and found a PSI that worked best for me.. almost always a bit higher than the manual says.

I drop it down to 20-30psi when I'm on a trail for the extra comfort, but then air it right back up when I find asphalt again.

Thanks all. I was concerned about even wear on the tires due to over/under-inflation.

I'm pretty sure in the US you go but the door sticker..The manual covers every model, which obviously is different.
