valve stem points inside on rear dual tires?

[Cooncatz]

I purchased a 98 Four Winds Class C in December and it has been parked since I brought it home. The snow is about gone so I wanted to check the air in the tires; but the valve stem on the rear outside tires are pointed inward and I can't see the stems on the inside tires - I assume I will have to crawl under the unit to check them.

Is this unusual - are the tires mounted incorrectly - is there a fix for this.
thanks

Great fit, durability, customer service.
Many have been fortunate to find parts that work at truck tire shops and some have found shops that will customize stock valves to fit RV needs. Some have home-brew rigs to get caps off, gauge on, air in, etc. Good for them, but the point is that good valves solve the air checking problems. And, they prevent slow leaks as well as catastrophic failures. Think of this:

1. BEST is a custom one piece heavy duty brass or steel valve

2. Extenders are OK if they're Braided Cover AND Airless, connected to METAL valves

3. NEVER put ANY extension/adapter/extender on RUBBER Valves

4. Replace Rubber with Metal (any kind!) at first opportunity

5. Class C's and probably everything American with 16, 16.5 or 19" wheels have .453" valve holes. Big truck wheels have .625" holes, so that reduces some of our choices when we go to truck stops and HD tire dealers.

Thing I like about our Borg Valves is that I can check and inflate anywhere. Bicycle pump, convenience store, interstate truck stop, doesn't matter. I carry a dual-footed gauge like shown above, but I can check just as easily with a free Discount/America's Tire gauge.

OH! Also added "Air Through" valve caps. Those rascals keep dirt out, provide a secondary air seal, and no unscrewing. Just push the gauge or air chuck onto them. They go by Gator, Crocodile, V2B. Available Amazon, NAPA...

I can check six tires in as many minutes and find that they still don't need air after months. We have Bridgestone R250's from Discount Tire. Between those tires, Discount's mounting, and the Borg Valves, adding air is about a twice-yearly process. Mostly when the seasons change and affect tire pressure. Drudgery became Pleasure.

X 2 I also have Borg extenders, they are great.

X2 The inside valves point to the outer rims, easy to check and fill w/ a long air chuck.

I had the same problem! I just loosen the valve stem and turned it so I could get a gauge on it.
Good Luck

Look into Dual Dynamics' Crossfire Tire Pressure Equalization System or Valve Stem Extenders. You can add air to duals at one easy access valve.

Here is a few page from years back that may be of help,some of the links are old and don't work but the info is good.
The kit looks like this.


The long ones go to the inside duel,coming out one of the holes in the wheel,the curved ones are for the outside duel facing out thru another hole and the short ones go on the front. Making it easy to check and fill your tires.

$5 :S

Your situation is normal. You need the tire chuck that is made for duallys that faces both ways. Also, a gauge with the same type of head.

Is there any more information on Tire Man extenders.

This! Also I have extenders... Cheapies. I just do not leave them installed all the time, but manually screw them on when I need them. Just a cheaper way to do it than buy expensive ones.

[IAMICHABOD]

I have to agree about the Tire Man valve stems,they make it easy and fast to check the tire pressure.
DO NOT put the extenders on them,they have a tendency to leak and if they come loose they can cause a catastrophic air loss. You need solid valve stems,many of us have these.

To check and fill the tires with the valve stems you describe you will need a duel headed inflator Like this

I had these installed on my E450

Best $200 (installed) that I have spent on the RV

This is normal with dual rear wheels. You can buy extenders to route them to the outside; go to a tire shop, they should have them but get the best ones you can get as the cheap ones seem to cause problems.
