What does the 105h mean on 245 60R18 105h?
R stands for “Radial” and the last two figures 18 indicate the wheel diameter in inches. The size ends with the load index 105, which is the maximum weight that each wheel can support, and the speed rating H, which is the maximum speed at which the tire is approved for use. H-Rated Tires: This is a perfect, average tire for most sedans and commuter vehicles. It might not seem to fit in our chart, but the tire speed rating “H” is rated for up to 130 mph. T-Rated Tires: This tire is often recommended for family sedans and vans. It’s rated for up to 118 mph.Letters ranging from A to Z represent the speed rating. Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).
What does 105h mean on a tire?
For passenger vehicles, load index ranges from 75 – 105. H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. Example load rating: (looks like 105T or 98V) The load rating represents the maximum weight that a tire can withstand (including the vehicle itself). For example, a 105T tire can carry up to 2039 lbs. A 98V tire can carry 1653 lbs.T and 102H are service descriptions. Load Index, what this means is, the tire is capable of carrying weight up to, 1,874 lbs per tire. The T and H are speed Ratings, this indicates that a tire is capable of speeds up to, 118 mph and 130 mph (respectively).The standard is set so that a rating of 100 is equal to 30,000 miles. The actual rating is a percentage of 30,000 miles. A tire rated at 200 has a projected tread life of 60,000 miles.
What does the H mean on a tire size?
Higher speed ratings, like H or ZR, can handle far beyond a normal highway speed. For example, “H” would translate to a tire that can only handle speeds up to 130 mph (or 210 km/h). Weather Conditions. Rain: H/T tires often perform better on wet roads due to optimized grooves. Snow & Ice: Some A/T tires are “Three Peak Mountain Snowflake” rated, providing excellent winter traction. Mild Conditions: Either can perform well depending on specific tire features.H-rated tires provide you with better control at higher speeds, which is good for both safety and performance, whereas T-rated tires balance a comfortable ride, longer life, and safe everyday driveability at moderate speeds.H-rated tires provide you with better control at higher speeds, which is good for both safety and performance, whereas T-rated tires balance a comfortable ride, longer life, and safe everyday driveability at moderate speeds.AT tyres are stronger than HT tyres, making them less likely to experience a puncture or tyre damage as a result of common off-road hazards such as rocks, ruts and tree roots. The strong sidewall of an AT tyre allows them to carry heavier loads and run at higher pressures than a HT tyre.
Can I fit H-rated tyres instead of V?
It is not recommended to fit new tyres with a lower speed rating to what is recommended for your vehicle. Whilst choosing to equip your car with a higher speed rating is safe, replacing your tyres with those of a lower speed rating will compromise the safety of your vehicle. Running a tire at speeds higher than its rating can shorten the tire’s life and potentially lead to a tire damage which could result in an accident, so it is important to follow the manufacturer’s speed rating recommendations when you are choosing tires.One of the most important aspects of any tire is its speed rating. The wrong tires with a less-than-adequate speed rating for your vehicle can cause safety issues, including tire failure and a loss in fuel efficiency.H-Rated Tires: This is a perfect, average tire for most sedans and commuter vehicles. It might not seem to fit in our chart, but the tire speed rating “H” is rated for up to 130 mph. T-Rated Tires: This tire is often recommended for family sedans and vans. It’s rated for up to 118 mph.
Can I mix T and H tyres?
Mixing different speed ratings on a vehicle is generally not recommended as it can affect handling and safety. So, mixing tyres on your vehicle isn’t just inadvisable, it can also be dangerous. It’s best to use tyres with the same speed rating across all wheels. Can I mix tires with different speed ratings? We strongly don’t recommend doing so.
