Toyota Tundra Tire Sizes Guide – Stock and Larger Tire Size Options

Trying to find tires for your Toyota Tundra? Here is a quick guide on what tire sizes the it uses. Plus, here is what you need to know when going larger.

What size tire do you have or want to have? Here is a handy guide.

There aren’t too many different tires sizes Toyota has used for the truck. Here are for the different types/sizes.

OEM Tire Sizes – Toyota Tundra

The majority of owners will fall in the 255/70 R18 or 275/65 R18 range. The larger R20s are special package upgrades for most buyers.

Lug Nut Patterns

The next step to finding tires is to check the lug nut patterns. This will generally seperate out 2wd and 4wd tires. Generally, 6 lug patterns are used in 4wd pickups while 5 lug patterns are more common on 2wd trucks.

How Tall Can You Go?

Undoubetdly the most common question asked is how large can you go with tires. It is a really easy way to add height to your truck and create a more “unique” look. While the Tundra has an ample amount of wheel well space, you can go to big and rub the tire.

The simplest way to go bigger is to just go with one of the sizes above. Going larger than this may mean:

1. Your truck’s speedometer and odometer can get out of whack with the larger size. You will then need to reprogram your truck’s computer to recalculate this for you.
2. Bigger tires may look cooler, but they have less low-end torque. Essentially, you are adding more rubber for the axle to turn which means they will turn slower – slower off the line speed. Consider that many off-road vehicles have a different rear axle to accommodate the larger tires.

Rules of Thumb to Remember

3% Height and Width. Most tire dealers also call this the “plus 1” tire size increase. Generally, you can increase your tire height and width by 3% each without having to do a lift or leveling kit.

An important note is that not every tire manufacture makes tires that are exactly 3% larger and this may not be an option for you.
1″ Lift = 1″ Tire Height. If you have a lift, you can go larger. How much? About 1″ inch per lift inch. Essentially, if you have a 3″ lift, you can add 3″ to your tire height. However, this doesn’t apply to width. Increasing width requires different backspacing.

Over-Sized Tundra Tires

Note: These recommendations are based on the factory wheels. Using an upgraded rim with different backspacing will allow you to increase to a wider tire. Also, if you go really wide, you will want to consider fender flares.

First Gen Tundra 

No Lift Kit
Max tire sizes are:

• 16″ rims: 275/70 R16 – 4/10ths wider, half-inch taller than largest factory tire size
• 17″ rims: 265/70 R17 – one inch taller but same width as factory
• 17″ rims: 275/65 R17 – 4/10ths wider, half-inch taller than largest factory tire size

1.5 – 2″ Leveling Kit (or less)
When installing a leveling kit, you might be able to fit some wider tires than what we have listed. It may require some trimming though, but it is possible.
Max tire sizes are:

• 16″ rims: 265/75 R16 – one inch taller but same width as factory
• 17″ rims: 275/70 R17 – 1.5 inches taller and 4/10ths wider than factory

3″ Lift Kit
With a 3″ lift kit, the options continue to get better. However, the wider the tire, the greater the likelihood of trimming.
Max tire sizes are:

• 16″ rims: 285/75 R16 – slightly more than 2″ taller than factory, this tire is 8/10ths wider than factory as well. This width may be problematic in tight turns and/or at full suspension compression.
• 16″ rims: 265/80 R16 – an oddball size, this tire is the same width as the factory but more than 2″ taller
• 17″ rims: 285/70 R17 – slightly more than 2″ taller than factory, this tire is 8/10ths wider than factory as well. This width may be problematic in tight turns and/or at full suspension compression.

Second Gen Tundra

No Lift Kit
Max tire sizes are:

• 18″ rims: 285/65 R18 – 5/10ths taller and 4/10ths wider than factory. Trimming may be necessary.
• 20″ rims: 275/60 R20 – one inch taller but same width as factory

1.5 – 2″ Leveling Kit (or less)
When installing a leveling kit, you might be able to fit some wider tires than what we have listed. It may require some trimming though, but it is possible.
Max tire sizes are:

• 18″ rims: 275/70 R18 – One inch taller but same width as factory.
• 18″ rims: 285/70 R18 – 4/10ths wider and 1.7 inches taller than factory. Trimming may be necessary.
• 18″ rims: 295/65 R18 – 1 inch taller, 8/10ths wider than factory. Trimming is probably needed due to width.
• 20″ rims: 285/60 R20 – 4/10ths wider and 1.5 inches taller than factory.

3″ Lift Kit
With a 3″ lift kit, the options continue to get better. However, the wider the tire, the greater the likelihood of trimming.
Max tire sizes are:

• 18″ rims: 285/75 R18 – 4/10ths wider and 2.8″ taller than factory.
• 18″ rims: 305/70 R18 – 1.2 inches wider and 2.8″ taller than factory. There are Tundra owners running this size, but trimming is required. Replacing the stock wheels with after-market 18’s that have less backspacing is recommended.
• 20″ rims: 285/65 R20 – 4/10ths wider, 1.6″ taller than factory.
• 20″ rims: 305/60 R20 – 1.2 inches wider and 2.4″ taller than factory. There are Tundra owners running this size, but trimming is required (it’s a tight fit).

Lastly, remember that when you shopping for tires, you may not find the exact tire you need for BOTH height and width. Manufactures make a range of tires to meet a general demand.
