What is the difference between 94 and 94h tires?
Load Capacity The "94" part of the 94T and 94H tire codes indicates load capacity, which is the same for both types of tires. A 94 load rating indicates that the tire can safely carry a load of 1,477 pounds. The rating is based on individual tires, so four 94T or 94H tires could support a car weighing up to 5,908 pounds, fully loaded.
What is the difference between a 95h and a 95T tire?
The 95H tire has a higher speed rating compared to the 95T tire. The load index rating, 95, is identical. Tire speed ratings, L thru Y and (Y), indicate the maximum speed the tire should be driven. L is for off road vehicles and indicates a maximum speed of 75 mph.
What is the difference between 94T and h speed ratings?
A speed rating of T indicates that the tire can be safely driven up to 118 mph. A tire with an H rating has a higher limit -- 130 mph -- which means it can be safely driven faster than the tire with the 94T code.
What is the meaning of T & H in tyre size 95?
While the 95 represents the load carrying capacity of the tyre which is 690kgs /tyre the T & H represent the speed rating which is 190 & 210 kmph. The adjacent comments on speed ratings & concomitant handling are all correct, but let me add -
What does 94H mean on tires?
Tire load index chart and understanding your tire's code In our example, the service description is the last three characters: 225/45R17 94H 94 is the load rating and H is the speed rating.
What does 95H mean on a tire?
The figure “18” indicates the wheel rim diameter in inches, while “95” is the load index, indicating the maximum weight the tire can bear; 95 equates to 650 kg. Then comes the letter “H” which is the speed index, where “H” signals a maximum speed of 210 km/h.
What is V or H rating on tires?
An “H” rated tire is designed to operate at a maximum speed of 130 mph. A “V” rated tire on the other hand is designed to operate at a maximum speed of 149 mph, almost twenty miles an hour more than the “H” rated tire.
What does H and W mean on tires?
The most common ratings are S and T (sedans, minivans, light trucks); H (some passenger cars, sports cars, coupes, some light trucks); N, P, Q and R (light trucks); and V, W and Y (high-performance and some electric vehicles). Most winter tires have Q, S or T speed ratings.
What does H speed rating mean?
130 mphSPEED RATING H If you recall from earlier, the “H” speed rating doesn't appear after “G” but between “U” and “V.” It represents a maximum speed of 130 mph (210 kph) and is commonly found on sports sedans and coupes.
Are H-rated tires good?
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 you mix V and H-rated tyres?
We'd never recommended mixing tyres with different speed ratings on your vehicle. It's safest to fit the same size and type of tyre, with the same speed rating, on all your wheels.
Can I use H-rated tires instead of T?
A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.
Can I mix V and W rated tyres?
Mixing tyre speed ratings isn't recommended. If you are in a situation where you must mix tyre speed ratings (after an emergency puncture, for example) then make sure the lower-rated tyres are on the front axle to prevent turning more sharply than you intended (oversteering).
Do speed ratings on tires matter?
The speed rating tells you the speed the tire can safely maintain over time. A higher speed rating usually means you will have better control and handling at higher speeds - and that the tire can take the extra heat. As a general rule, tires with higher speed ratings also handle better at slower speeds.
What is the difference between AT and HT tires?
AT tyres have a deeper and more aggressive tread than HT tyres. This provides greater grip in off-road conditions. Generally speaking, the stronger, thicker sidewalls of an AT tyre make them less likely to suffer damage caused by common hazards encountered off-road, such as rocks, ruts and tree roots.
Does speed rating affect comfort?
Speed ratings affect more than just speed, they also contribute to ride comfort, wear, and cornering capabilities. In general, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.

How much weight can a 94 tire carry?
A 94 load rating indicates that the tire can safely carry a load of 1,477 pounds. The rating is based on individual tires, so four 94T or 94H tires could support a car weighing up to 5,908 pounds, fully loaded.
What is the recommended tire load rating for a replacement?
Automobile manufacturers recommend that replacement tires have at least the same load capacity and speed rating as the original equipment tires. If the original tires on a car were rated at 94H, someone replacing a tire with one rated 94T should be aware that the replacement tire has a lower speed rating than the original tires on the car.
What is 94H code?

THE ORIGIN OF SPEED RATINGS
We can thank Germany’s famous Autobahn for tire speed ratings. Tire speed ratings range from A (the lowest) to Y (the highest). But the chart is not completely in alphabetical order. For example, H is between U and V, with the common perception that H stood for “high performance” at one time.
SPEED RATINGS REFER TO MORE THAN JUST SPEED
Contrary to the name, speed ratings aren’t just about speed. They’re also about ride comfort, wear and cornering ability. Typically, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.
MIXING SPEED RATINGS
We certainly don’t recommend it, but if tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle regardless of which axle is driven. This is to prevent a potential oversteer condition.
LOAD INDEX
235/55R17 99H- The load index (99) is the tire size's assigned numerical value used to compare relative load carrying capabilities. The higher the tire's load index number, the greater its load carrying capacity.
What Is Tire Speed Rating?

What is the difference between a T tire and a H tire?
As previous comments noted the difference is in the rated maximum speeds that they are designed to be driven at. A T rated tire (118mp/h/190km/h) is generally a more all round general purpose tire while a H rated tire (130mph/210km/h) will generally be designed to have better handling and grip with the higher speed advantage.
What is the maximum speed of a tire?
Tire speed ratings, L thru Y and (Y), indicate the maximum speed the tire should be driven. L is for off road vehicles and indicates a maximum speed of 75 mph. On the other end of the spectrum, Y indicates use up to 186 mph and (Y) indicates speeds in excess of 186 mph although the rating does not indicate how far in excess of 186 mph or 300 kph the tires can be used. Tires with a T designation are rated for a maximum speed of 118 mph or 190 kph. They are common on family cars, vans, and suvs. Tires with an H have a maximum speed rating of 130 mph or 210 kph and are common on sporty cars.

When were tire speed ratings invented?
Tire speed ratings were first established in Germany in the 1980s to help drivers pick the correct tires for the high speed autobahns. The speed ratings were initially in kilometers per hour, making the conversion to miles per hour somewhat odd for certain speed ratings like 149 mph for the V rating.
How much pressure is a volt tire?
The tire always looks a bit deflated compared to the other 3, even though it's inflated at 40 PSI. BTW, I checked the pressure with my gauge, with a convenience store tire pressure, and of course with the volt built-in TPMS system, and they all show around 40 for that tire. The other 3 OEM tires are inflated at 36PSI.
