Two Tires, Carrying Everything
A road bike tire has a contact patch only about 2-3 cm wide, yet it must bear your entire body weight, your pedaling force, and braking friction. Choosing the right tire and taking care of it is a basic skill every cyclist should master.
Choosing Tire Width
The trend in recent years has been toward wider tires:
| Width | Best For | Characteristics |
|---|---|---|
| 23mm | Old-school road | Lowest rolling resistance but least comfortable |
| 25mm | Traditional road | The old mainstream |
| 28mm | Modern road | Current mainstream, best overall balance |
| 30-32mm | All-around road/light gravel | High comfort |
| 35-45mm | Gravel | Suited to gravel roads |
Tire Types
| Type | Description | Best For |
|---|---|---|
| Clincher | Most common, uses an inner tube | General use |
| Tubeless | No inner tube, sealed with sealant | Low tire pressure and puncture resistance |
| Tubular | Tire and tube bonded together, glued to the rim | Racing |
Tire Lifespan
| Usage | Rear Tire Life | Front Tire Life |
|---|---|---|
| Training | 3,000-5,000 km | 5,000-8,000 km |
| Racing | 1,000-2,000 km | 2,000-3,000 km |
| Commuting | 5,000-8,000 km | 8,000-12,000 km |
The rear tire wears about 1.5-2 times faster than the front, since the rear wheel bears more weight and transmits drive force.
Signs Your Tire Needs Replacing
| Sign | Severity |
|---|---|
| Wear indicator has disappeared | ⚠️ Time to replace |
| Multiple cuts on the tread | ⚠️ Time to replace |
| Casing fabric is visible | 🔴 Replace immediately |
| Bulge or deformation on the sidewall | 🔴 Replace immediately |
| Frequent flats | ⚠️ Casing may be fatigued |
Tips to Extend Tire Lifespan
- Maintain correct tire pressure: Underinflation accelerates sidewall wear
- Avoid locking up the brakes: Skidding wears a flat spot into the tread
- Rotate front and rear: Swap front and rear tires every 2,000 km for even wear
- Inspect after every ride: Pick out embedded gravel and glass shards
- Store properly: Store inflated and out of direct sunlight
Tire Recommendations for Taiwan’s Road Surfaces
| Surface Type | Recommendation |
|---|---|
| Urban asphalt | 28mm, commuter tires with thick puncture protection |
| Riverside bike paths | 28mm, low rolling resistance training tires |
| Mountain roads | 25-28mm, racing tires with strong grip |
| Gravel sections | 32mm+, tires with a fine-particle tread pattern |
Popular Brand Recommendations
| Brand | Flagship Product | Characteristics |
|---|---|---|
| Continental | GP 5000 (S TR) | All-around king |
| Vittoria | Corsa Pro | Exceptional grip |
| Michelin | Power Road | Great value for money |
| Pirelli | P Zero Race | F1-derived technology |
| Schwalbe | Pro One | One of the top tubeless choices |
| Maxxis | High Road | Taiwanese brand, consistent quality |
A good pair of tires may cost only 2-3% of the total price of your bike, but their impact on ride quality can be as high as 30%. This is one of the best-value upgrades you can make.
