1998 Volvo A40 tire valve stem?

[ed978]

About a year ago I picked up a 1998 Volvo A40 articulated hauler. Today I went to move it and found one of the tires a little low. When I went to air it up I found that the valve stem is larger than all my other equipment. Searching the net I find information about large bore, super large bore, z-bore, and Mega, but the sizes don't match. There is nothing in the service manual. The valve stem on this truck has a diameter of 0.475" or 12mm. Can someone recommend the correct Inflation gauge?

Welcome to the forum! I think they are going to be large bore,you can get a adapter’s if you don’t want to buy more gauges and chucks

Hi thanks shopguy. I wasn't sure because I found this chart showing a large bore is 4.826mm, a super large bore is 11.175mm, and a z-bore is 14.224. Using digital calipers on the stem on the truck it has a diameter of 12mm.
