What size tires will fit on a stock Jeep Wrangler?

However, when it comes to conventional factory sizes, the Wrangler often comes with 15"–17" tires. The first set of digits (255) represents the width of the tire in millimeters. The second number is the height of the tire in centimeters. For example, a 255/75R-16 has a width of 1501mm (59.9 inches) and a height of 75cm (29.5 inches).

Jeep only offers three sizes of tires: XJ, JK, and YJ. These names come from the years the vehicles were built. The XJ model was produced from 1971 to 1997. The JK model came out from 1998 to 2006. And the YJ model was made from 2007 forward. Today, most people think of a Jeep as having four wheels, not three. However, back in the day, two-wheel-drive models were labeled JK, and four-wheel-drive models were called XJ.

Both two- and four-wheel-drive models use the same tire sizes.

What PSI should my Jeep tires be?

Jeep Wrangler Tire Inflation From 2005 until 2021, the Jeep Wrangler was available in 30 trim levels, each with 15 original equipment tire size sets and a recommended tire inflation range of 29 psi to 43 psi. As you might expect, higher-trim models came with larger tires that required lower pressures for comparable handling.

Today, the only model still being produced is the JK (jeep grand cherokee). It comes in two trims: Sahara and Rubicon. Each has three sizes of tires: all-season, mud terrain, and rock crawl.

The recommended tire pressure for the JK is:

Sahara: 1st and 2nd rows- 29 psi; 3rd row- 34 psi

Rubicon: 1st and 2nd rows- 29 psi; 3rd row- 34 psi

Both rows use the same pressure. The car's weight plus cargo volume determine which rows have more or less load than the others. For example, if you drive mostly in city traffic, leave your spare key in the ignition, and carry a small amount of gear, then you'll need fewer pounds per square inch (psi) under the vehicle to keep it stable on its wheels.

When checking tire pressure, always refer to the manufacturer's recommendations.

How do I know my jeep tire size?

The first number (33) refers to the tire's full-length diameter in inches, measured from the ground to the top of the tire. The following figure (12.50) represents the tire width in inches. The final number (15) represents the rim's diameter in inches. For example, a 33-12.5-15 wheel fits an SUV with tires sized 33-13-16.

You can use this formula to find out the approximate tire size for your vehicle:

Size = [(Vehicle Full Length) - (Wheel Base)] / [Wheel Diameter] + 2

So, if your Jeep is 70 inches long and your wheel base is 37 inches, then its tire size should be calculated as follows:

Size = 70 - 37 = 33

Then, divide 33 by 12.5 to get 3 degrees of inflation. Since 10 pounds per square inch equals 1 degree of pressure, you'll need to add 10 to the calculated number to get the actual pressure your tires should be carrying.

If your car or truck has factory-installed tires, it will usually say which size goes with each one on the sidewall. If not, you can estimate them using our sizing guide. There are three main types of tires: sedan, wagon, and off-road.

Can I fit 33s on a stock Jeep Wrangler?

A 33-inch tire may be installed on a factory Jeep Wrangler JK, but only with little clearance on the front bumper and insufficient clearance for complete off-road articulation. The tire should be mounted with it being centered on the axle.

The problem with installing larger tires is that they need more room for wear. This means removing some of the existing suspension components so the tires can move up and down freely. Also, larger tires tend to have lower pressures which can cause handling problems at low speeds.

You will need to remove some parts from your Wrangler to install these large tires. Here's what you can expect to lose:

- Front end lift kits will give you more ground clearance but also require more torque to get started in cold weather conditions.

- Rear drop-in suspensions will remove the rear axle housing and attach it to the frame instead. This reduces unsprung weight and provides better traction by distributing most of the vehicle's weight over a wider area.

- Off-road tires will require special equipment to handle difficult terrain; usually this involves adding extra steel to the chassis or purchasing an aftermarket kit. Without such modifications, your Jeep might not be able to climb over rocks as easily or traverse rough surfaces without risk of damage.
