Inflating Tyres to your required pressure.

I'm trying to do a comparison between the Ring RAC 900 and the T Max... I can see that the T max delivers 160 lts per minute but I can't find the comparable "lts per minute" pumped by the RAC900? Does anyone know what the figure is by chance? They both seem to be recommended by all on here, so I'd just like to see which one might suit me best.. The RAC900 is about £80 on Amazon at the moment and the cheapest I've seen the T Max is £98...

Update... I have just found a listing that quotes "Flow rate 55 litres per min."... quite a bit less than the T Max!

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

Although I can only speak for my self, I bet a LOT of other people will be thinking the same................Cos I did not get a Fiat pump with the van !

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.

Two or three minutes I would say but you could be out of puff at the end, I argue its all good exercise and I can then have an extra choccy biccy with my next cup of tea.

If it takes 30 minutes you are definitely doing it wrong ;)

never timed it myself, when i say decent i mean a floor/track one not the old style that attaches to the bike (can you still get them?) but definitely a lot less than 30 mins for all 4 tyres
use it for the bikes and the rear air assist as well
 
I too use the compressor supplied with my Fiat based van. Have a Lidl bicycle pump that works as well, bit of exercise though.

Our old Hymer had tyre pressures of 80psi, as we had a slow puncture and to get to the garage I used my stirrup type bicycle pump that I used for my racing bike (typical pressures of 90 to 110psi). It was a hot day and I was even hotter when I reached the correct tyre pressure, so I quickly decided to buy a Ring electric pump should I need to pump the tyres in the future! So bicycle pump is excellent emergency solution for the tyres and to get fit!
 
I did not try to use the supplied Fiat pump, they do not include them on Renaults. They do supply a spare tyre though.
May I also add that my Chinese bike pump looks very similar to the one illustrated earlier but there was no chance of using it to inflate my tyre.
 
Have a look at this one. I bought it to inflate my Land Rover tyres, and carry it in my Hymer. It needs the engine running to work, but is very good.

edit: Mine is actually the 88P model which 120psi.

Thanks for all the replies and suggestions. The more you look the more confusing it gets. The RAC900, sort of takes my fancy, and seems priced somewhere in the mid range, around £80.
So, the 12-99 ones on Ebay through to the £130+ ones like Peppadog has, what are the differences? Is it just build quality of the unit, as they all seem to be claiming the same.
 
It’s a ymmv situation ?
My double barrel pneumatic car tyre pump & push on pressure reading wasn’t coping with the MH tyres so I looked at this forum for advice & bought the RAC900

it’s working well for me but I’ve no comparison to garage pumps or rival similar pumps.
I power it from the MH vehicle battery and can easily reach all MH tyres with the supplied hose.
The on/off switch is on the pump so for the rear tyres I have to travel back to the pump to alter that, or work with mrskevenh as a team ?

I fancy the VanHaus one. The Ring pump needs access to the battery terminals; a bit of a pain in our van.

Will order one when back from France.
 
Nigel L did you not have a pump come with your van on the three Fiats we have had they all had a compressor with tw options air only and another for putting tyre repair gunk into the tyre.?

We had a Bursner on a Fiat base in 2016, and that had one, but our 17 plate Autotrail V-Line only has the spare wheel and the basic jack and supporting items to just be able to change the wheel. No compressor!
 
I have a basic bike track pump in the van. Does the van & the bike, although if I had to do a van tyre from fully flat I expect I would need a coffee break half way through.

Just adding the last few psi as a result of normal losses over some months of use is not enough to raise a sweat. I should point out that just walking upstairs is about all it takes to bring me out in a sweat. ?

It doesn't have a built in gauge. I have a good quality dial gauge to check pressures.
 
? my track pump had a fitting too fat to attach to my MH valves. The wheel trims make the area to cramped.
Not a fan of wheel trims so maybe I should see how the bare steel looks ?

With Fiat based motorhomes I think you only get the pump, which is primarily there to put the repair gunk in, if you do not get a spare wheel. One or the other. I got one because I did not get a spare wheel, but I subsequently obtained a spare wheel so now have both. As I have said before the pump works fine for us.

If the pump you go for doesn’t require you to connect directly to the battery, the pump will not be man enough for the job. There’s a reason the better ones connect directly to the battery.

I hear what you say but there do seem to be some cordless ones that are man enough. See posts #9, #10, and #13

Ingwe the ones you refer to are all battery operated and derive their power therefrom and not via a cigarette power point.

The current required to run a heavy duty compressor is beyond that available from such points.

Ian
 
Ian, thanks but I wasn't proposing to connect via a cigar lighter or other 12v point. I am proposing buying a cordless, i.e. A battery operated one. Like the Van Haus one or the Ryobi 18v. (y)

Great stuff, you’ll have to let us know how they perform.

I don't have that problem with on board air :D

I have terrible trouble with wind, oops sorry, I meant air so I bought my auto pump from Europarts £29. Set the pressures go for a cuppa and when I get back all done 65psi in the rears no problem, you only get what you pay for. I only buy tyres that stay up and don’t leak. If they do then the wife takes them back they argue with her.

I also have the Ryobi one inflator and it copes very well with the pressure needs on the van. We also carry a ryobi flashlight as well, the same battery powers them both

Most forecourt airlines go to 80 psi. If you need higher then try the hgv fuel area , often have airlines in with the pumps and they go plenty high enough.
