why more air in rear tires

[ron717]

what is the reason for more air in rear tires, and what is best recomodation, or do I just use what is on door?

I guess if you carry stuff,my sticker is wrong,it says 46 in rears and the max on tires is 44.I run 40 front,44 rear,with 255/60/17.

My stock '08 V6 17" sticker says 39 front 46 rear (I think, sitting at desk, not in car ), and that's what I pump them.

Where did you see the tires are only rated for 44?

I saw it on the tires,says 44 max.cold.

Nobody likes sitting on hold, but I would call VWoA and get their take on this. If the sticker says 46, yet the tires say 44, I'd be interested to hear what VW itself recommends. Are these tires in question 255/60-17 106H?

For the record, the sticker in my '05 V6 with 255/60-17 106H tires states 36 front and 44 rear. The stock Dunlop ST8000s I think maxed out at 51 psi, while the Pirelli STRs (which are now OEM, and what I ran before) were 44psi max. My current Nittos max at 35psi, but are oversized (265/70-17) with a higher load rating (113). So, they can actually support more weight with less air pressure.

I called vw,they said to go by the sticker on the door,I said I have two stickers,one on door itself,and one on door jamb.I waited for 20 minutes and he said I have optional tires,and go by the door sticker.I think I got a bad rep,at first he said 46 was ok,then 44,then he talked about some kind of optional tires,I said they came with the car,then he said 44.

I double checked my sticker for my '08 V6 17", 39 front, 46 rear.
And the scorpion tires state 44 max, very suspicious.

I submitted a web support request to VW about a week ago, asking about the 46psi vs. 44psi max, and today I received a phone call, asking me for pictures of the stickers.

I took some pictures, and discovered a second sticker on the bottom side of the driver door, may be the same as reported by JKUCSMA. This sticker recommends 44psi for the rear, this still seems too high given the tire max is 44psi.

maybe bc of 26 gallons of gas in the back, but then that would not make sence bc the engine is in the front and the is alot more weight then the gas
