What Size Tires Do Jeeps Have Stock?

Tires are an important part of the overall look and feel of a vehicle. 

When it comes to cars, sporty-looking models usually have sportier tires that stick out just enough with good treads to give the vehicle a masculine look, while luxury rides usually have tires that are wider and less aggressive in style.

Jeeps are no exception to this rule, although there is some variation within the Jeep community as not everyone uses “stock” size wheels for their ride. 

What Size Tires Do Jeeps Have Stock?

31-inch tires are the standard stock size for most Jeeps. However, jeep owners who want their vehicle to stand out from the rest often go slightly bigger. The traditional tire size for Jeeps is 33 inches, but some owners will go as large as 35 or 37 inches. These larger tire styles give a bulky and large look while retaining that rugged “every-man” style.

I was surprised to find out what options I had regarding tire size on my jeep. However, I also found several factors played into this choice.

Can I Use 31-inch tires?

Jeep owners who want to go smaller when it comes to tire size will often use 31-inch tires. 

As I stated before, this is a popular choice amongst Jeepers because it retains that rugged style with a touch of compact poise.

These tires fit perfectly on the stock wheel style of a Jeep. 

For example, if you have a standard size Cherokee, you will also have standard-sized wheels measuring 17 inches in width and 6 1/2 inches in diameter.

However, if you have a new Wrangler with larger alloy rims at 18 inches wide and 7 inches thick, a 31-inch tire will not fit on these wheels.

Can I Use 33-inch Tires?

33-inches can be an ideal option for those who want their Jeep to have the ultimate macho look, but certain factors need to be considered before going with this size.

Again, if you opt for standard-sized alloy rims, you should be fine since they are approximately 6 3/4 inches in width and 18 1/2 inches in diameter. 

The only issue that you may run into is that 33-inch tires might rub against the fender if they are pushed to their limits.

These are the largest size tires you can use on a stock jeep without investing in a lift. Yet, certain models have larger alloy rims that are not compatible with these larger-sized tires.

Can I Use 35-inch Tires?

Jeep owners who have their hearts set on riding with larger tires will usually go with 35-inch models.

These tires work best with alloy rims measuring 7 inches in width and 18 1/2 inches in diameter.

However, these tires will not fit on standard-sized alloy wheels and could result in rubbing against the fender if pushed to their limits.

Can I Use 37-inch Tires?

The ultimate macho tire size is the 37-inch variety.These massive tires are also great for those who want to go off-roading because they have lots of extra strength and power.

The only problem with these tires is that they are too big for stock alloy rims, which measure 6 1/2 inches in width and 18 1/4 inches in diameter.

Calculator For Stock Jeep Tire Size

Now that you know what the four most popular tire sizes are for stock Jeeps, let’s look at how to calculate what size tire to get for your ride. 

If you want to change the size of your tire, you can use a general formula. Start by multiplying .12 by your Jeep’s tire diameter (Example: .12 X 38″ =4.56).

It is the ideal tire height for clearance between your vehicle and the road. 

The next step would be to add 4 inches to this height (Example: 4 X 38″ = 152.4 + 4 = 156.4). This is the ideal tire width for your Jeep.

When Do I Need Larger Rims for a Stock Jeep?

When my jeep needed tires bigger than the standard 33-inch size, I had to get alloy rims.

These larger rims will allow for wider and taller tire styles that will fit your vehicle’s lift kit perfectly.

Jeepers can buy these wheels through Jeep dealerships or other retailers specializing in off-road vehicles. 

A 37-inch tire will not fit on stock alloy rims because standard-sized alloy rims only measure 6 1/2 inches wide.

How To Decide Tire Size

Not all 33-inch tires will fit all Jeep wheels. The wheel needs to be designed for these tire sizes, and larger wheels will need larger-sized tires, as well.

For example, a 33-inch tire on a 16-inch rim won’t fit properly and will rub up against the fender of the Jeep, which defeats the purpose of putting those bigger tires on in the first place.

The general rule is to use one size larger tire than what is listed on the wheel. 

Of course, you should always double-check to make sure it will fit your particular model.

Buying Wider Tires

It’s also important to note that not all 33-inch tires are wide enough for a Jeep.

Some models of Jeeps come equipped with larger flares, fenders, and bumpers than others, and this changes how much room is available in the wheel well.

If you need help determining what size tire is best, most tire companies offer a chart for tire sizing and compatibility.

Some people prefer a wider tire than what comes in stock sizes. For example, 33-inch tires are available in both nine and ten inches in width

It might sound like a large difference, but in fact, it’s not. 

The increase in tire width is only an inch on each side of the wheel (totaling two inches total). 

Keep this in mind when shopping for a new set of tires – a little difference goes a long 

Way.

How To Find Wider Tires?

Not all tire companies offer wider tires, but they have a section specifically for off-road and performance tires.

Some companies will even give you the option to build your tire by choosing the tread pattern, size, and sidewall.

It’s important to note that some companies charge more for wider tires than what they list for their stock sizes. 

Also, not all wide or bigger size tires will fit on all four-wheel styles, so make sure the width and height of the tire you choose are compatible.

When purchasing a wider tire, you need to pay attention to the overall height as it will affect how much clearance you have within the wheel well. 

For example, a 33-inch tire with a five-inch sidewall will be higher than a tire of the same size with a four-inch sidewall.

What About Off-Road Tires?

Off-road tires are built more for performance than looks or comfort. They typically come in smaller sizes of 37 inches and up.

However, if you’re driving on-road, it’s not recommended to use these types of tires as they are too aggressive and don’t provide enough tread for wear and tear.
