What do 107 and H mean on a tire?
In numbers like that, 107 is the load rating and H is the speed rating. The numbers are the tire’s load index rating. The letter is the tire’s speed rating. The biggest thing you need to know is what speed and load index rating is required for your specific year, make and model of vehicle.
What is the difference between H and T speed ratings for tires?
In your samples, H (130 MPH) is a higher speed rating than T (118 MPH), and the numerals represent load rating per tire, so higher numbers represent higher load ratings.
What is the difference between the first and the second tire?
The first tire has a smaller load rating but a higher speed rating. It can take higher speeds for a longer time compared with the other. What's more important is that these are two completely different tires. One is a P-Metric tire which is well suited for the kind of driving and towing you mention.
What does 113t mean on a tire?
So, what does the T or H mean on tires? The “T” or “H” on tires pertain to their speed ratings. 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.
What does the S or H mean on tires?

What is load range H?
From a G to an H Truck tires typically come in two load ratings: G and H. Load range G is a 14-ply configuration, while load range H tires have 16 plies. The heavier-rated tire will usually add between 700 pounds and 1,000 pounds more load-bearing capacity per tire (see "How Much is Too Much," next page).

What does 112t mean on tires?
Though not an absolute, the general rule is: The higher the speed rating, the better the tires will corner and stop, the faster they'll wear out, and the more they'll cost. Common speed ratings on tires are as follows: R=106 (mph) S = 112, T = 118, H = 130, V = 149, W = 169 and Y = 186.

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.
