Why do the tyres of the Suzuki Swift wear out unevenly in Pakistan?

Uneven tire wear on a Suzuki Swift in Pakistan is a common issue due to a combination of road conditions, driving habits, and maintenance practices. Here’s a detailed breakdown of why it happens:

1. Poor Road Conditions
Roads in many parts of Pakistan—especially urban areas—are full of potholes, speed breakers, and uneven patches.

Frequent impact with these surfaces causes the suspension and wheel alignment to shift, leading to uneven tire contact with the road.

Impact:
This results in inner o r outer edge wear, commonly seen on the front tires.

2. Improper Wheel Alignment
Swift’s suspension geometry is sensitive to misalignment, which is often neglected o r done incorrectly at low-cost alignment shops.

Misaligned camber, toe, o r caster angles cause one side of the tire to wear faster.

Impact:
Feathering, cupping, o r slanted wear patterns.

3. Irregular Tire Rotation
Many Swift owners don’t rotate their tires regularly every 8,000–10,000 km.

The front tires wear faster due to steering and braking loads, leading to imbalance over time.

Impact:
Front tires may show more wear on edges, rear tires may last much longer.

4. Incorrect Tire Pressure
Overinflation o r underinflation—common due to reliance on inaccurate air gauges at petrol pumps—causes:

Overinflated tires to wear in the center.

Underinflated tires to wear on the edges.

Impact:
Inconsistent wear across tread surface.

5. Worn Suspension o r Steering Parts
Worn-out shocks, struts, o r bushings in older Swifts o r high-mileage vehicles cause instability, especially on bumpy roads.

This leads to uneven tire contact with the road surface under load.

Impact:
Uneven tread depth, excessive bouncing, o r noisy ride.

What You Should Do:
Get a 4-wheel alignment every 6 months o r after hitting potholes.

Rotate tires every 8,000–10,000 km.

Maintain correct tire pressure usually 30–32 PSI.

Inspect suspension components annually.

Use reliable tire brands suited for local road conditions e.g., Dunlop, Yokohama, Continental.
