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 is a 125 load index?
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 does 121 load index mean?
Tire Load Index Capacity
The rating of 121 shows that it has a load capacity of 3297LBS. Multiply that by four tires (4 x 3,297 = 13,188 pounds) to get your vehicle’s max load carrying capacity. Always remember to install tires that have a load index that is equal or greater than your original factory-installed tires.
What is a good tire load index?
The higher the tire’s load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original. Most passenger-car tire load indexes range from 75 to 100, but some are higher.
Is a higher load index better?
If you’re thinking about up-sizing, you can switch to a tire with a higher load index, because that means your tire can safely carry more weight, but you can never go down.
Will a higher load index tire last longer?
Why Is Tire Load Index Important? The tire load index tells you how much weight your tire can carry, and overloading your tires is never a good idea! When you put too much weight on your tires, you can cause damage and wear them down prematurely. Even worse, you run the risk of experiencing a tire blowout.
What load range tire do I need for my truck?

Is it OK to use higher load index tire?
It’s absolutely crucial to the safety of your driving experience that you select a tyre with an appropriate load rating for your vehicle’s needs. If in any doubt at all, always go for a higher load rating than you need, as this won’t cause any harm to your vehicle.
Is higher tire pressure better for performance?
Larger tires and higher inflation pressures provide more load capacity, while smaller tires and lower tire pressures provide less. Correctly inflated tires receive appropriate support from the contained air pressure to provide an even distribution of load across the footprint and help stabilize the tire’s structure.
