Tire Diameter
The first thing to consider is the diameter of the tire. The 305 45r22 tires have a diameter of 32.81 inches, and the 33×12 50r22 tires have a diameter of 33 inches. That means that the 33-inch tires will be taller than the 305 45r22 tire size. This can be good or bad, depending on what you’re looking for.
If you want a taller tire, then the 33s will give you a little more ground clearance. That can be helpful if you’re doing any off-roading or just want extra protection from potholes and other road hazards. However, taller tires also mean that your vehicle is going to be higher off the ground. That can make it more challenging to get in and out of, and it can also affect your gas mileage because there’s more air resistance.
If you want a shorter tire, then the 305s will be a better option. They’re going to be easier to get in and out of your vehicle, and they’re going to offer better gas mileage. However, you may sacrifice some ground clearance and protection from road hazards. It’s really up to you to decide which is more important to you: the taller height or, the shorter height. There are advantages and disadvantages to both.
Section Width
The next thing to consider is the section width of the tire. The 305 45r22 tires have a section width of 12.01 inches, and the 33×12 50r22 tires have a section width of 12.52 inches. That means that the 33-inch tires are going to be wider than the 305 45r22 tires.
Wider tires can be good because they offer more traction. That can be helpful if you’re doing any off-roading or if you live in an area with a lot of snow and ice. However, wider tires can also be more challenging to handle, and they can cause your vehicle to feel “floaty” on the highway. If you do a lot of highway driving, then you may want to stick with the narrower tires.
Circumference
The last thing to consider is the circumference of the tire. The 305 45r22 tires have a circumference of 103.07 inches, and the 33×12 50r22 tires have a circumference of 103.73 inches. That means that the 33-inch tires are going to be longer than the 305 45r22 tires. The difference in the circumference is 0.66 inches or 0.6%.
Revolutions Per Mile
The 305 45r22 tires have an RPM of 614, and the 33×12 50r22 tires have an RPM of 610. That means that the 33×12 50r22 tires are going to make fewer revolutions per mile than the 305 45r22 tires. The fewer revolutions per mile, the less fuel your vehicle is going to use. So, if you’re looking to save money on gas, then the 33-inch tires might be the way to go.
Sidewall Height
The last thing to consider is the sidewall height of the tire. The 305 45r22 tires have a sidewall height of 5.4 inches, and the 33×12 50r22 tires have a sidewall height of 5.51 inches. That means that the 33-inch tires are going to be taller than the 305 45r22 tires. The difference in the sidewall height is around 0.11 inches or 1.9%.
Wheel Size
Rim size is an important thing you should consider when choosing the right tire size. The 305 45r22 tires can be used on a 22-inch wheel, and the 33×12 50r22 tires can be used on a 22-inch wheel.
Construction Type
The main difference between 305 45r22 and 33×12 50r22 Tire is in the section width. 33×12 50r22 Tire size is 0.51 inches or 4.3% wider than 305 45r22 Tire size. Both tires can be used on a 22-inch wheel. If you are looking for a taller tire, 33×12 50r22 is a better option.
