Where do the glowing reviews come from?

And finally, the most persuasive argument in favour of using a gas mixture in wheels: motorists’ reviews. Why do motorists praise gas in tyres, you ask? It is very simple, there are two whole reasons for that.

The first reason: the tyre fitters’ pressure gauges. You will laugh, but on the gas hoses they often lie by around 0.1-0.2 atm. On the high side, naturally! As a result, every “gas” customer’s tyres end up under-inflated by exactly that difference in the reading, which, depending on the make and model of car, can produce a stunning improvement in ride comfort. Either way, the car will become at least a little softer: an under-inflated tyre takes on much more of the load from bumps in the road and passes less of it on to the suspension.

The second reason is psychological. For someone who has paid money for a service, it is very hard to admit, even to themselves, that they have simply thrown the money away and been “taken for a ride”. On top of that, tyre-fitting marketing makes active use of positioning tactics: after all, there are different gases too, “two-component” ones, the sort of thing for the middle class, and then “four-component” ones, which must be the VIP option. And a green valve cap on the wheels, apparently, is also thought by some motorists to add a certain respectability to its owner.

To sum up. Filling your tyres with gas cannot harm your car in any way, and that is definitely a plus. But the only benefit of gas in your tyres is a green cap for passers-by to look at, and nothing more than that. Incidentally, you can buy the cap separately, so filling with gas is not actually necessary for that. On the whole, the decision on whether to spend money on this is yours to make; either way, you will not do the car any harm.

P.S. Can you mix gas with air?

Many tyre-fitting shops try to “tie” the customer to their own magic cylinder and hose, telling them that mixing gas in tyres with air is categorically not allowed and even dangerous. What’s more, sometimes the customer is not even told the name of the gas mixture, while being firmly assured that mixing different mixtures is not allowed either.

Given everything written above, it can be stated with full confidence: any gas mixture pumped into tyres at a tyre-fitting shop can be mixed with air, and with other gas mixtures too! So if you have already decided to spend money on a green cap, do not worry: you will be able to top up the wheel anywhere, at any moment. The whole article on why gas in tyres is unnecessary
