How to Tell the Tire Size on a Jeep Rubicon

The tire size on your Jeep Rubicon can vary by year, but most models come standard with 33s, but you might be able to go smaller or bigger.

Not everyone is familiar with tire sizing, especially if the vehicle is purchased through a private sale. 

You are probably missing some of the manufacturer’s paperwork detailing the vehicle’s specs.

A previous owner may make modifications that include switching out the factory tires.

Don’t worry; you can still find out the tire size without heading to the dealership.

Tires are sized in millimeters or inches. Both measurements use sets of numbers to reference the tires’ height and width.

In millimeters, the first set of numbers is the tire’s width, and it denotes the diameter from top to bottom in inches.

The second set of numbers gives you the speedwell aspect ratio in millimeters. The percentage lets you know the height and width of the tire’s sidewall. 

Tires not using the metric system use the second number set to reference its width in inches.

The third number set is in inches for both measuring systems. It denotes the diameter of the rim.

A capitalized alphabet letter is included between the second and third number sets. It refers to the tire’s inner build and should be an R for radial. 

An occasional Rubicon owner may find a B. It stands for Bias Ply, and you often see these tires on vintage vehicles.

Radial and Bias Ply Tires

Bias Ply tires are pretty easy to recognize. The tires have a slightly smoother and narrower tread, giving them a classic look.

The name references the internal construction. 

Nylon and polyester cords form a crisscrossing pattern at 30-45 degree angles, and the overlapping cords create a strong but rigid tire with a narrow tread.

Radial tires use ply cords crossing at 90-degree angles. You get a strong tire with a wider tread for more traction and grip. 

Unlike narrow tread tires that can’t conform to the road, radials can grip it with ease. 

The flexible cords conform to the terrain and skim over rough trails.

With a wider footprint, radials give you improved traction on wet surfaces, along with improved cornering. 

For off-roaders, traction is critical over the classic appearance of Bias Ply tires.
