So, having had the use of a compressor, have always been on top of keeping my tyre pressures spot on.
However, no longer have the compressor, so my questions is:-
What pressure do the air lines go up to on garage forecourts?
Presumably not high enough to cope with the higher pressures required over cars etc
So just curious to know what people do to check and maintain their tyre pressures.
Thanks.
 
Forecourt Airlines simply won't do it.

You need a Ring RAC900 mini compressor etc
I have a cheap maplins version, capable of pressurising a modified 20 ltr Aldi compressor tank to 115psi in around 7 minutes but I had to fit a cooling fan.
 
Garage air lines go high enough.
My works van runs higher than MH and I never have a problem.
65 psi.

Supermarket airlines always seem to go above 80 psi. Never had a problem.

Both Morrison and Sainsbury locally don't go above 50psi.
Both pre-set by user pressure type and stops at 50psi.

Anyway, you need air in an emergency you're going to need a long forecourt airline.
 
I had a tyre begin to deflate in Spain so went to the first garage I came to. It would not go above 40lb and actually let more air out.
Sitting in a hypermarket car park the tyre was almost down too far to drive but no problem as I have a big Chinese bicycle pump. I managed half a dozen pumps then realised I was not heavy enough to push the handle down. Then discovered a pump, a proper pump at the Hypermarket. Owing to the length of their airline, the layout of the site, I could only use it by blocking half of the exit. Which I felt obliged to do, being in Spain. After all it was a Spanish screw that had embedded itself in my tread.
 
Cordless rechargeable tyre compressor. One charge last for many tyres and its so convenient the pressures get checked more frequently. Around £40 from Amazon.
 
We have a Ryobi OnePlus inflator, does our van tyres to about 79psi, it can go alot higher. Handy if you need other tools such as drill etc...

That sounds like a very good solution. How big is it, is it small enough to carry with you?
Do you have a link?

I use a cycle track pump. I need it for the road bike anyway so not lugging any additional gear around. Pump the bike tyres up to 95 Psi but probably don’t need that much for the van !
 
I know not why but believe me, there is no way that I could hand pump my van tyre beyond 42psi. Bikes must be in a different league. I do own one of the get you home kits with a pump but as I never get punctures and the 150kg load in my garage was very iffy.....
 
I bought this
www.vonhaus.com

Cordless Tyre Inflator - 12V

Effortlessly top-up tyres, sports equipment, toys and more with the cordless, portable power of the VonHaus 12V Tyre Inflator.
www.vonhaus.com www.vonhaus.com
Along with a quick release adapter for about £3 from amazon

I got fed up with hanging the corded compressor out of various windows to get it to reach all the tyres. And it’s great for the bike tyres too.
Much easier job now and doesn’t take up much space to store. Also in an emergency it can be used in a corded mode.

It isn't the pressure, its the volume of air.
Look at a bike tyre next to a van tyre.
If you pumped the volume of air you pump into a van tyre into a bike tyre there would have been a very loud bang a while ago.
 
Pop ours into our local kwik fit.
Pop a couple of quid into the Dougie Mac collection tin. Everyone's happy ?

Got myself a heavy duty 15amp ext. lead that clips onto leisure battery plus added an ext. tube that clips on instead of screws on. So that with the heavy duty compresser supplied with van does the job .its the get you home type compresser that can pump in the sealing fluid but I carry a spare .
 
Morrisons - up to 70 psi no problems. But have an ECP proper 12v screw on pump style for when away from supermarket lines.
 
decent bicycle pump, used it on the van because my 12v pump didnt go to 70psi but i now use the bicycle one on all our cars
 
Most, though not all, air lines in garages will easily supply enough pressure... However, the gauges are woefully inaccurate as a rule
Even the gauges supplied on a lot of the 12v pumps are not great

I would urge you to buy a decent gauge .. Not a cheapo one off of fleabay, and use that rather than rely on something that has been used and abused for heaven know how long

Same one as Stroppy Bird above. Size of a cordless drill but much lighter. Only charges from mains but lasts ages. It can be operated direct from 12v with a supplied lead. I also carry a conventional double cylinder compressor 12v for any major inflation though have never needed to use it.
 
Ring RAC 900 here as well. Can't remember how many garage forecourt air pumps were either broken, not accurate or just not able to reach 5.5 bar. And like a few people i've had that situation where i've turned up and checked my tyre pressure, needed to top them up only to realise that i was actually deflating them due to a crappy pump at a garage....
 
Another vote for Ring RAC 900. Brilliant piece of kit

You need to change where you shop PJ. ::bigsmile:

I always use one of two Sainsburys in our area to top up tyres as they both have plenty of room on the forecourts. Both use the preset pressure setting and in both cases they go up to at least the 4.5 bar (65psi) I put into my rears.

I find that the 12V electric pump that came as part of the spray gunk tyre repair system with my Fiat based motorhome also gets up to that pressure as well, although it takes its time and I keep the engine running while I use it.
 
After a Funster suggested this type of option we bought this https://www.wiggle.co.uk/topeak-joe-blow-max-hp-track-pump/? (up to 160psi!) to try & it works very well plus this TyrePal tyre pressure gauge https://www.tyrepal.co.uk/product/wsl-digital-tyre-pressure-gauge/ . Not a lot of money for the convenience at home & can be carried on trips if wanted too.

My Ring pump went phuttt getting up to 95psi on four tyres, even though I rested it, so I bought a T-Max which is a beast. Did not tell Management ‘cos she would get excited about that much money to just pump up tyres. :gum:

How long does it take to say, increase the pressure by 4psi?
I remember years ago, my dad getting a foot pump. I let out the air in his tyre and tried to pump it up again with just the foot pump. After about 30 mins I was knackered and the tyre looked about as flat as when I started! Had to put the spare on and drive it to a garage.
That's why I'm surprised you've suggested an ordinary cycle pump.

Just a question, why doesn’t anybody use the actual Fiat pump which comes with the van, I always do but it just takes a little longer to pump up

Nah! I do all my tyres with my Maplins RAC copy and an accurate gauge if I can be bothered to get my garage airline out.
The mini compressor gauge went walkabout years ago, as did the carry handle, plastic cover and two of the rubber feet
