The load index of this tire is “126” – 3,748 lbs for a single-wheel rear axle, and “123” – 3,417 lbs for a dual rear wheel application.
What does 123 120r mean on a tire?
Service description: 123/120 R 123. Load index – single wheel fitment. 120. Load index – dual wheel fitment. R.
What does 121R mean on a tire?
The 121R sequence tells us the tire’s maximum load rating or the amount of weight the tire can bear (in kilograms; in this case 121), and the R gives us the speed rating, or how fast the tire can safely rotate. The lowest rating (speed) that you’d usually see on a passenger car is Q, which is equivalent to 99 mph.
What does 125 R mean on a tire?
The next number (12.50) is the width, and the “R” that follows indicates that this is a radial tire.
What does 126 123R mean on tires? – Related Questions
How fast can an R rated tire go?
What does R and R tire mean?
R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction. 17 The last dimension listed in the size is the diameter of the wheel rim, which is most often measured in inches. LOAD INDEX AND SPEED RATING.
What does R mean on a tire size?
Radial tires are the most common tires on the road in the United States today; thus “R” will usually be shown in the tire size designation. Radial construction means the tire’s internal ply cords are oriented in a radial direction, from one bead over to the other, essentially perpendicular to the direction of rotation.
What load range is 125?
Higher load index ratings mean your tires will be able to handle a heavier load. In this example, there are two numbers. The higher number (load index) is for single rear-wheel applications.

What is a 125 load rating?
As It Pertains to GVWR
And because a load index of 125 means that each tire can carry 3,638 pounds apiece (14,552 pounds in total), the truck is more than capable of operating at its 10,000-pound GVWR safely.
What is a Type R tire?
The Type R rolls on wheels and tires designed for exceptional acceleration, cornering and braking. The Type R Touring shows off big 20-inch alloy wheels wrapped in super-sticky maximum-performance 245/30 ZR20 tires33.
Which is better D or R tire?
A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. A radial tire will normally run cooler than a bias ply tire, especially when the tire is under a load. A tire that runs cooler will last longer. For those reasons I would recommend an R tire over a D tire.
What does the R in Type R stand for?
Type-R stands for ‘racing‘. Honda’s engineers set out to develop a racing car for the road, one that would give drivers raw thrills and an immersive experience. They succeeded. The first Type-R impressed even one of the world’s greatest racing drivers – Ayrton Senna.
What size are Type R wheels?
The Civic Type R shows off 19-inch alloy wheels wrapped in super-sticky maximum-performance 265/30 ZR19 Michelin Pilot Sport 4S tires33.
Does the R in tire size matter?
Tire Speed Rating
The speed rating is the letter that follows the load rating, but you may also see it following the “R” on some tires. This indicates the maximum speed the manufacturer designed the tire to handle.
Does the R on a tire mean rim size?
The lower this number, the shorter and more aggressively the tire sits on the wheel. The R means the tire is of radial construction (they all are) and the 18 is the diameter of wheel the tire fits, expressed in inches.
What is ZR vs R tire?
The Z in ZR corresponds to an old label used by manufacturers to indicate that the speed index is higher than V, i.e. 150 mph. Thus, a ZR tyre has a speed index of V, W, or Y. R indicates that the structure is RADIAL.
What does the Z and R mean in tire size?
ZR: This isn’t necessarily relevant to the tire’s size but rather the construction, with the “R” meaning that it’s a radial tire (the Z refers to speed rating, most tires will have construction only here—only Z-rated tires have the speed rating here)
Does Zr mean run flat?
The following letter(s) describe the construction: R is for radial; ZR stands for a Z-rated radial (see service description); and ZRF means Z-rated run-flat (rare).
How fast can ZR tires go?
ZR Designation
Tires having a maximum speed capability over 149 MPH may have “ZR” in the size designation. Tires with a maximum speed capability over 186 MPH are required to include “ZR” in the designation. Below are examples of tire sizes with a “ZR” speed rating.
What does the ZR stand for?
The letters ZR on the sidewall relate to a tyre’s speed rating, which in this case is 150mph. That means it should not be driven at speeds in excess of 150mph (240kmph) – of course, where such speeds are even legal! Before 1990, ZR was used for high-performance tyres.
