A must have for any motorist is a tyre pump. Having this in the boot of your car can get you out of many a sticky situation. Numerous times I’ve relied on one when a leaky valve was causing problems, or when I’ve been miles away from civilisation and the tyre pressure warning has popped up. It also saves that monthly trip to the garage…those 50p’s add up!
Ring are well known for their quality car maintenance equipment, and I’m still using the same one we reviewed years ago. So what’s this new updated version like?
The Ring RAC635 is a 12v cigarette lighter powered compressor to pump tyres up with. It comes with a digital guage that can be pre-set to the correct pressure, once it hits that number the pump will automatically switch off.
Pressure ratings can be switched from PSI, KpA and bar, the pump will also measure the current pressure. At one end there’s a white and red light, for either normal illumination or as an emergency light.
It comes with a set of adapters so you can inflate bikes, footballs and other inflatable items. There’s also a soft carry case to store it in.
The compressor has a max pressure of 80 psi and should inflate a tyre to 35 psi from flat in under three minutes.
Build quality is great, it feels far more substantial than their older pumps. The cable seems longer too, measuring in at 3.5 metres it allows you to reach to the front and back of even the largest cars with ease.
The plastic does mark easily though, if you allow it to fall over onto tarmac it will mark. So be careful with it if you want to keep it in good nic.
On the end of the connector there’s a small air pressure release button, which is handy when you overfill or find a tyre is already at a higher pressure.
The pump can run with the ignition off or on, it seems to work faster with it on but there’s nothing in the manual to say either/or.
You change the pressure measurement by the small wheel just beneath the backlit dial. Press it to change and then turn it to set the desired level.
