Tyre Speed Rating Chart — Complete Guide for Pakistan

Understanding your tyre’s speed rating is essential for safe driving in Pakistan — particularly on motorways where speeds of 120 km/h are common, or on GT Road sections where vehicles travel much faster. The speed rating is a letter code stamped on the tyre sidewall that indicates the maximum sustained speed the tyre can safely handle. Using a tyre with an insufficient speed rating can cause catastrophic tyre failure at high speeds. This complete tyre speed chart guide explains every speed rating code, what it means, and which cars in Pakistan use which ratings.

What is a Tyre Speed Rating?

The speed rating is part of the tyre’s service description — a combination of load index and speed rating found after the tyre size. For example, in 195/65 R15 91H:

• 195 = tyre width in mm
• 65 = aspect ratio (sidewall height as % of width)
• R = radial construction
• 15 = wheel diameter in inches
• 91 = load index (615 kg per tyre)
• H = speed rating (210 km/h maximum)

Tyre Speed Ratings for Common Pakistani Cars

Here are the factory-fitted speed ratings for popular cars in Pakistan:

Speed Rating and Temperature Resistance

A critical fact about speed ratings that Pakistani drivers must understand: speed rating is directly related to heat resistance. A tyre with a higher speed rating doesn’t just go faster — it’s engineered to manage the heat buildup that occurs at sustained high speeds. In Pakistan’s hot summer temperatures (40–50°C ambient), tyres already operate under thermal stress. Using an under-rated tyre compounds this danger significantly.

Can You Use a Tyre with a Higher Speed Rating Than Required?

Yes — using a tyre with a higher speed rating than the vehicle requires is always safe. A T-rated car fitted with H-rated tyres will benefit from the additional heat resistance and handling capability. The concern is lower ratings, not higher ones.

Consequences of Using Under-Rated Tyres in Pakistan

• Tyre blowout: The most serious risk — heat buildup causes sudden tyre failure at speed
• Void insurance: If a road accident is caused by incorrect tyre fitment, comprehensive car insurance claims may be partially or fully rejected
• Reduced handling: Under-rated tyres have softer compounds that distort under cornering, reducing steering precision
• Rapid wear: Operating near the maximum rated speed causes accelerated tread wear
• Legal liability: In Pakistan, using non-compliant equipment is a traffic violation if detected after an accident

Pakistani drivers frequently buy replacement tyres from local shops that may not stock the exact original fitment. Here’s how to ensure the replacement is appropriate:

Conclusion

The tyre speed rating is not a performance specification for speed enthusiasts alone — it is a fundamental safety parameter for every Pakistani driver. Given Pakistan’s hot climate, potholed roads, and motorway use, choosing tyres with an appropriate speed rating and ensuring they haven’t exceeded their age (replace tyres over 6 years old regardless of tread) is critical. Always verify both the speed rating and the load index when replacing tyres, and consider running costs including fuel prices when selecting between tyre compound options that affect rolling resistance and fuel economy.
