I have 4 aluminum wheels and 4 32" all terrain tires mounted on the Jimmy. I want to take them off and put them on the toyota for this weekend. I can't get any of the FOUR valve stem caps off. They are a different kind than normal, instead of a cap with grips on, they have a hex sort of shape (not sure if it has 6 points or not) so I can't get it off. I think its seized. I gripped the valve rubber part with pliers and tried twisting the cap off and it won't come off.

Any ideas on how to take it off? Thanks
 
No seriously, I dont want to wreck the valve stem so I can't try harder.

Someone please give me good help:doah:

I agree with Masiony. Put a pair of pliers on the valve stem and a pair on the cap and try it that way. Why do you need to get the valve stem cap off just to put the tires on your 'Yota? Is it just to air them down?

Rick

PS: try spraying them down with some PB Blaster.
 
if it is the same chrome hex ones ive seen, just run a socket on it. if it spins the valve stem, then put a pair of vise grips at the base to keep it still. but seriously, all this fuss for a vavle stem? they are like a buck a piece. just man-handle that thing.
 
steve, if twisting the cap off ruins the stem, the stems were rotten and in need of replacement anyway.

Sorry, to clarify my first post...

One tire is completely flat, so i NEED it off. The rest I just want to get off so in the future when I NEED to air down/fill up I can get them off.

They are the "chrome" ones your talking about, but they are pink (previous owner) and I will try a socket on there.

Are valve stems universal, or do I need a certain kind for a certain rim?

I will try harder I guess. Thanks guys
 
Thanks. Should I get new ones? I ripped up the rubber, its almost all off. Just the stem tube is showing. I got the cap off though, it was corroded on.

Thanks
 
You should go ahead and replace all of them. I started using the metal chrome ones that screw together with a nut on each side of the rim. As far as the types of valve stems, 95% of them are the smaller valve stem. The bigger ones that I've seen are usually on farm implement type tires. :D

Also, if the base and stem are rubber, if you can get the bead broke loose from the rim you can use a razor blade to cut the base off and it should fall right out.

If you get the rubber ones, just use a pair of pliers to pull them up through the rim. Just be careful not to tear them up. If you buy the metal ones just use a couple of wrenches. Just make sure not to over tighten them. :D

Oh yeah, a little bit of soapy water lets them go in a lot easier.

my 15x10 steels had the larger hole. they are nothing special as far as rims go. and walmart had the valve stems for 1.88 for a pair. if you use rubber ones, spray a little paint on the hole before you try and put it in. it will lube it up a little while the paint is still wet. then when the paint dries it will help seal it. just the plier method mentioned above. if you do it right, it goes right in without a struggle.
 
Hey steve. Got any progress pics on the jimmy? Last I checked in you had just taken it off the frame, then winter set in. So it's been about a year or so... lol.

The blazer got scrapped. Not enough money or time for that and my Jimmy. Kind of regret scrapping it, I wish I could have sold it for a bit more money. Oh well it was fun while it lasted...
 
Also if you have a metal cap for the valve stem, thread that on there and grip the metal cap with the pliers instead of the valve stem. This will keep you from chewing up the rubber part when you pull them through.
