I have removable valves on my wheels (see picture) and need to pump my tires up. My car is in winter storage in my garage and has summer tires on, so a trip to the gas station is not desirable. I have bought a small compressor that plugs into the cigarette lighter, however none of the fixtures/adapters that I have will fill the tire with air.



Has anyone else experienced this? Suggestions?

Thnaks - Mark.

 

Yeah, those little valves are a pain to get air into. Unfortunately, just about your only bet is to get a tire chuck with a screw in air hose fitting and hook it into a small pancake style compressor. I'm sure someone else will chime in with a better answer than mine. But this is what I've had to deal with on several of my customers XKR's/XJR's.

 

Mark,
You can't put Norwegian air into a British tyre! If you think this is a joke, you are right!!
Seriously, you can't expect a tiny 12V compressor to inflate a completely flat tyre; it's just way too much volume. You need to get a real 110/220 Volt compressor.
Much easier than taking each wheel to local service station and with a real compressor, you can use an impact wrench to remove the wheels.................but then you do need a torque wrench to tighten the nuts!
It's only money!! Jaguars deserve the best! And of course you should have a code reader but that's another subject.............

Hope this helps, Adrian

 

This is the best portable air compressor I ever had:
It connect to your battery and puts out a lot of air, it also has a screw on valve.

 

Those little cigarette lighter compressors WILL fully inflate a tire, but it would probably take at least an hour. They are mostly rated between 200 and 300 PSI, but with an abysmal CFM rating. (Some claim to "Fully inflate a passenger car tire in eight minutes") Of course, an hour of running would more than likely fry the little things.

 

Thanks for the input guys.

Just to clarify... the tires are only partially deflated and I just need a top up. I want to try and keep them inflated to around 60psi to avoid flat spots during the winter lay up. A 12V compressor should be able to do the job. It seems it is the connection between valve and compressor which is limiting the procedure.

Brittania... As I am an Expat Aussie, I am sure I assist in the negotiation between Norwegian air and British rubber :-)

I have been advised (on other forums) to go with a clamp connector, and will source this next week.

Until then gentlemen, let the snow melt fast and the salt wash away even faster!

 

Go to your auto parts store and buy a portable air tank. A 5 gallon tank costs between $50 and $60 in the U.S. Buy a regular tire inflator and screw it onto the hose. Go to your local garage, ask nicely and they'll fill it to 120 psi for nothing. You'll have plenty of air to top up your tires.
Re this 60 psi inflation pressure you speak of. Check the maximum inflation pressure on the tire sidewall and I strongly suggest you do not exceed that. If you choose to do so remember, now you are the test pilot...
Regards,

 

Adrian,

If you use an impact wrench to either loosen or tighten the OEM Jaguar lug nuts, you risk damaging one or more of them. They are 2-piece nuts, with a chrome outer cover that is easily stripped. If that happens, you'll have a hard time removing that stripped nut. It's stripped against the inner nut and not the thread, so the socket will turn but spins and doesn't engage the inner nut. There have been many threads about these OEM nuts on this and other model forums.

Don't let anyone use an impact wrench on your Jaguar. Protect your nuts!

Mark,
FYI, my Hankook tyres show 50 psi MAX ! That's at max load...........unloaded?
just don't know, so be careful ...................

I don't use an impact wrench to tighten nuts but at 81 yo I do need a little help undoing things! And I do use a crow bar to put wheels on after aligning studs with holes, works just great!

I get my British air from BA daily flights from LHR to SEA but it has to be dried and then kept in a waterproof container (Seattle!!).

My 2007 XK Coupe is best Jag I have ever owned except maybe the E Types.

Cheers, Adrian

 

And my Bridgestones say 40 psi MAX !

 

I tried using this stuff but every time I opened it I lost the air. https://www.rt.com/uk/331438-bottled-british-air-china/

 

Thanks for the response to all.

I have now bought an adapter that fits and the max tire pressure on my Pirelli P Zeros is 50psi. They are now pumped up to that pressure. The little compressor had a hard time from 40 up to 50psi, but we all need a workout sometimes :-)

I had generalized on the max pressure as I coundn´t remember and it was minus 10deg C here and a trip out to the garage wasn´t that tempting.

Now we wait for snow/salt free roads and the driving season!

Cheers - Mark.
