Tire Care: Pressure, Wear, and Roadside Fixes
Updated May 29, 2026
Tires are the single component you should check most often. Correct pressure, early wear detection, and a small repair kit prevent most rides from ending early.
Set pressure for the surface and the rider
The right pressure is a range, not a single number. Every tire is printed with a minimum and maximum on the sidewall; stay inside it. Within that range, lower pressure adds grip and comfort on rough or loose surfaces, while higher pressure rolls faster on smooth pavement. Heavier riders and loaded bikes sit toward the higher end.
| Surface | General tendency |
|---|---|
| Smooth pavement | Toward the higher end of the printed range |
| Crushed gravel / rail-trail | Middle to lower end for grip and comfort |
| Loose or technical terrain | Lower end, still within the printed minimum |
Use a pump with a gauge and check before most rides. Tires lose pressure naturally over days, and narrower tires lose a noticeable share faster than wide ones.
Valve types matter
Two valve types are common: Schrader (the wider automotive-style valve) and Presta (narrow, with a small lock nut you unscrew before inflating). Make sure your pump head fits your valve, and carry an adapter if you ride bikes with both.
Inspect for wear before it strands you
A quick visual check catches most problems:
- Tread and casing: look for cuts, embedded glass or thorns, and a flattened or squared-off centre tread.
- Sidewalls: cracking, fraying, or bulges mean the tire is near the end of its life.
- Wear indicators: some tires have small dimples that disappear as the tread wears; when they vanish, replace the tire.
Prevent flats
Most punctures are avoidable with a few habits: keep pressure in range, pick lines around debris, and pull out small embedded shards before they work through the casing. On routes with thorns or glass, puncture-resistant tires or sealant reduce stops.
Fix a flat on the road
Carry a spare tube, two tire levers, and a pump or CO2 inflator. The basic sequence:
- Shift to a small gear, then remove the wheel.
- Use levers to lift one bead over the rim and remove the tube.
- Find the cause: run a finger carefully inside the tire to locate glass or a thorn, and remove it.
- Inspect the tire for cuts; a temporary boot can cover a small slice.
- Lightly inflate the new tube, seat it inside the tire, and work the bead back on by hand where possible.
- Inflate to your target pressure and refit the wheel, checking it is seated and the brake clears.
