Nitrogen for tyres
Nitrogen filling at the workshop on Dairy Flat Highway. It holds pressure more steadily than compressed air, so your tyres spend more of their life at the pressure they should be at.
What it does, and what it does not
Ordinary compressed air carries moisture, and moisture makes pressure swing as temperature changes. Dry nitrogen is a larger, more stable molecule that also seeps through the tyre wall more slowly. The practical result is that a nitrogen filled tyre drifts away from its set pressure more slowly than an air filled one.
That matters because under inflation is the single most common cause of premature tyre wear, and most people do not check their pressures anywhere near often enough. A tyre that holds its pressure wears evenly and rolls with less resistance, which shows up in fuel use.
We will also say what it is not. Nitrogen is not a substitute for checking your pressures, and it will not rescue a tyre that is already worn or damaged. It is a small, useful gain, not magic.
Because it needs the generator at the workshop, nitrogen is not something we can bring out in the van.
Honest summary
- Pressure stays steadier for longer
- Less moisture inside the tyre and on the rim
- More even wear across the tread
- Still check your pressures now and then
- Workshop only, not a mobile service
533 Dairy Flat Highway, Albany. Ask when you book a fitting.
What to look out for
Steadier pressure
Less drift between checks, which is where most under inflation comes from.
Even wear
A tyre at the right pressure wears flat across the tread instead of on the edges or the middle.
Less moisture
Dry gas rather than damp compressed air sitting against the inside of the rim.
