What do the markings on a tire mean?

The markings indicate different information:

205 – tire width (mm),
55 – aspect ratio (%),
R – radial tire,
16 – rim diameter (inches),
91 – load index,
V – speed rating.

What should you pay attention to when buying tires?

Choose the correct size for your vehicle.
Select summer, winter, or all-season tires based on climate.
Check the production date (indicated by the DOT code, e.g., DOT 2223 = 22nd week of 2023).
Prefer tires with A-grade for good grip and durability.

What are all-season tires?

All-season tires are designed to be used in both summer and winter. They're suitable for moderate climates, but in severe winter or icy conditions, winter tires offer better performance.

How can you change the tire size?

Changing tire size should follow the manufacturer’s recommendations. It's best to consult a professional to select a suitable size for local conditions.

Should snow chains be used with winter tires?

Snow chains are only necessary in extreme snow or icy conditions, even with winter tires. Always match chains to road conditions for safety.

Can winter tires be used year-round?

Winter tires perform best in cold, snowy, and icy conditions. Using them in summer increases wear and reduces efficiency, so year-round use is not recommended.

Can a spare tire be used instead of buying a new one?

Spare tires are for emergency use only and should not replace a regular tire for long-term use.

Should new tires be installed in the front or rear?

New tires are usually installed on the rear axle to improve vehicle stability and handling.

What should tire pressure be?

Tire pressure should match the manufacturer’s specifications, usually found on the door frame or fuel cap. Regular checks and seasonal adjustments are important.

What are the risks of under- or over-inflated tires?

Under-inflation increases wear and fuel consumption. Over-inflation can reduce grip and cause faster wear.

Is there a difference when inflating tires with nitrogen?

Nitrogen helps maintain more stable pressure and increases tire lifespan. It expands and contracts less with temperature changes.

When and how should tire maintenance be done?

Regular inspections are essential. Balance and rotation should be done every 10,000–15,000 km. Tread depth should be above 1.6 mm.

When should tread depth lead to tire replacement?

If tread depth falls below 1.6 mm, the tire should be replaced.

What is the lifespan of a tire?

It depends on usage and quality, typically 5–6 years. Tires older than 10 years (from manufacturing date) should be replaced for safety.

Can tires be repaired?

Small punctures or damage can be repaired. Severely damaged or heavily worn tires should not be repaired.

Why are tires black?

Due to carbon black in their composition, which improves durability and wear resistance.

What factors should I consider when choosing a tire?

Pay attention to size, load and speed ratings, seasonal suitability, production date, brand, grip performance, noise level, and durability.

When should a tire be replaced due to wear or damage?

Replace when tread is under 1.6 mm, or if there’s sidewall damage, deformation, or air leakage.

How to know if tires are suitable for high speeds?

Check the speed index printed on the tire’s sidewall.

How to measure tire pressure?

Use a tire pressure gauge. Follow the vehicle manufacturer's recommendations based on tire size and type.

Why are some tires asymmetric?

Asymmetric tires have different inner and outer designs to improve performance in various driving conditions.

Why does tread direction matter?

It enhances grip and helps channel water away from the tire, especially in wet or icy conditions.

How long does it take to change a tire?

Usually 15–30 minutes, depending on tools and experience. Safety precautions are important during roadside changes.

When should tire balancing and rotation be done?

When tires are changed, or every 10,000–15,000 km, or if there's uneven wear, noise, or vibration.

What’s the difference between all-season and summer tires?

All-season tires suit various conditions, while summer tires are designed for warm weather and offer better grip.

Why is low tire noise important?

It enhances driving comfort and reduces disturbance to others on the road.

Are there special tires for electric vehicles?

Yes, EV tires are designed with lower rolling resistance to improve energy efficiency and extend range.
