Changing tire on A3?

[jaymcb]

Sorry for the obvious question, but I am on my phone and can't search a TM. What tool is needed to get the spare tire on an A3 down? No tool kit in mine
The tire company says they can't do anything without the tool.

You need an inch and a half socket. Tough tool to come by.

Pretty sure all you need is the lug wrench. Think it's 1 1/2"

 

[jaymcb]

is that all? Don't you need a 1.5" impact socket just to get the wheels off?

 

[gimpyrobb]

You use the socket to loosen the nuts holding the tire in place on the spare mount. Then you swivel it so the lug nuts fall through the holes and the weight is suspended on the hoist. Then you lower the hoist by undoing the saftey latch and lower tire to ground with socket on the draw bar.

Loosen the nuts, then flip the latch, then kick the tire to get the nuts aligned up with the holes. Let the tire and wheel free fall. No sense eating a tire iron or breaking an arm.

If the shop can't figure it out, let them break something.

Are you talking about lowering the tire from the carrier behind the cab?

A 1" square handle fits the bar that is the hand wench. If they don't have one, a Crescent wrench and portable jack against the tire will work.

If your tire shop is having this much trouble just lowering the tire, I'd look for another shop.

The shop comes at a recommendation from another member.

I will pass this info on, and thank you to all who answered!

If you decide to lower the tire by using the 1 1/2 inch bolt/cable/winch setup watch out cause the A3 tire is one heavy momma. And will do a number on your body if you are not careful. When I lower my A3 tires I really do a death grip on the socket handle (I use a 1 inch socket set).

Addition: I just looked up the weight of the tire and wheel "382 lbs" as per TM 9-2320-386-10, page 3-28. The warning paragraph on the bottom of the page says to always have another person with you when removing or installing a wheel. Having done the procedure I would go along with that.

IN section 3-9 of that TM< there is an illustration of the CTIS valve, with a short line between the valve and the tire.

Does anyone know where a line and nut set can be obtained? I have one with a crack. If it splits, I am out of luck.

This isn't the one you have to take off to get the wheel off, but rahter the one between the CTIS valve and the tire itself. I'd hate to lose another week for one line!

IN case anyone has pointers, it is for the left side middle axle.

I also emailed tdealmeida@cmautomotive.com to see if he has a source.....

I just got one from Erik. M35A3 Wheel Valve, 12448915

 

[jaymcb]

Does that have the line too? It just shows the valve in the picture and description, and there was only an answering machine when I called

 

[AceHigh]

If he is there he picks up. I just asked him for the brass parts I needed- they did not show up in his webpage- and he shipped overnight. Great service.

 

[jaymcb]

Just called him, and he was very helpful. He's going to his 'box of CTIS parts' to see if he has what I need. Fingers crossed.....REALLY want to get my hands on my truck...so the money can really start flying out of my wallet

If you choose to kick the tire to get it to twist off the carrier, be carefull to pay attention to where the ctis vavle is . During the Twist I hit the brass elbow of the hose on the spare tire carrier causing it to snap off . I had to use the hose and elbow off the flat tire to replace the one on the spare I broke.

 

[jaymcb]

anyone know how to get a 395 to fit in the spare tire carrier?

15.5 is the same size as a 395(basicly).

There is something I don't understand here. The spare tire does not have a CTIS wheel valve, weight, or any tubing. Simply mount it and use it. If you have another wheel besides the flat you removed with a cracked piece of tubing, temporarily remove the tubing from the wheel with the flat and use it. If the flat is the one with the cracked tubing, just drive it without a spare and fix it later. Or, you can buy new tubing from Grainger, McMaster-Carr and other places.

If you are recovering the A3, do not turn on the CTIS. Inflate the tires to 60 PSI and the truck will drive better without so much wobble. The wheels are red-lined at 60 PSI so don't go over 60.
