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.

:confused: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 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.

Here are some pics:

If it were me, I'd go with the sticker UNLESS that value were greater than what's on the tire. In that case, go with what's on the tire.

In the US, tire manufacturers are required to publish, on the tire's carcass, the maximum save inflation pressure for that carcass. Any overinflation can lead to damage to the carcass, especially if driven for extended periods.

Note that this maximum inflation pressure also applies to the pressures needed to seat the bead while installing the tire onto the wheel. We had a tire installer who had a lot of tires with belt separation issues on quality-brand tires (Dunlops, michelins and Goodyears, if I remember correctly. The shop owner did a little investigating and foind one of his installers using up to 100psi ov pressure to seat the bead -- WAY over what the tire was rated for. The tires got over-pressurized, and the carcass got damaged, leading to the belt failures.

Tires are complex beasts. It's best to adhere to the manufacturer's recomendations, in all cases. If you can find out the amount of load the front and rear tires will be carrying, you can always call the tire manufacturer to get a tire pressure recomendation. I'd use THAT in place of the VW recomendation. The manufacturer knows his tires better than VW does, ESPECIALLY if its a brand of model that VW doesn't normally install on the car.

If you have tires that won't handle the placard spec. you got the wrong tires.
What do you mean by "the wrong tires?"

If the tire can handle the vehicle load (i.e. the tire's loading at GVWR does not exceed the tire's load capacity,) then the tire is up to the load imposed by the vehicle, regardless of whether the tire's maximum pressure is above or below the manufacturer's recomended inflation pressure.

Pirelli STR ,255/60/17,08 vr6 If you look at the pictures GVWR is over 6000lbs.,tires handle like 2250 each.
According to Pirelli USA'a web site, the load index for that tire is 106, meaning a load capacity of 2094 lbs per tire.

Ubnfortunately, their techinical data page does not include your size, but most other similarly-sized tires in that line are spec'd to 44psi.

I'd inflate to no more than 44.

(And truthfully, I'd probably air mine up to 42, check wear patterns and tire temps, and adjust from there. As a racer, I have the gear to do that properly -- most folks don't.)
