My 2012 requires only 38 psi in the rear tires. Are you sure you need 46 psi? Of course, the higher pressure is the reason that VW requires "XL" (extra load, or reinforced to handle higher pressures) tires on the Touareg.

 

yes, mine is 2010. front is 39psi and rear is 46psi ....

 

Exactly which 2010 Touareg model and wheel/tire sizes have you got?

 

2010 VR6, 255/60R17 106H

 

Are you sure you bought tires with the XL load rating, or not? That max air pressure on your tires, to me, indicates it is perhaps not the proper load rating for your vehicle, or that it is not a truck tire.

 

It is a truck tire. Where do I find XL load rating tires? I searched tirerack, but couldn't fine any XL tires for 2010 touareg VR6.

 

That 106H rating, not sure if that is right, when your car weighs 500 pounds more than my 2012, and mine runs a 108 XL ???? Better double check the tag on the drivers side door jamb near the sill for tire load specs again.

 

I am sure it's 106H. MY OEM tires are 106H rated. That's what confuses me.

 

You may be forced to find another brand of tire with a higher max tire pressure rating, don't know what else to suggest to play it safe in your vehicle.

 

235/65/17 V 108 XL and 255/60/17 V 106 were the OEM petrol 3.2 specs with both sets running at 36 psi/Front and 38 psi/Rear on half load and 38/44 on full load.

The only difference between H and V is the sustained maximum speed and either is acceptable.

What does the door sticker actually state for 2010 VR6 tire sizes and for half load and full load tire pressures?

[Were 17 inch wheels a standard fitment on the VR6?]
