Toyota Tundra Tire Sizes Guide - Stock, Larger And Lifted Size Options

Are you in the market for new tires for your Toyota Tundra? Looking to go bigger or wider? Here is a guide to what you can and can’t do with a stock truck.

Toyota has used only a few different tire sizes for the Tundra. Below are the different types/sizes for each production year.

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.

How Tall Can You Go?

Undoubtedly 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 too big and get some rubbing.

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 rob low-end torque. Essentially, you are adding more rubber for the axle to turn which means they will turn slower, particularly off the line. Consider that many vehicles set up for off-road use different axle gearing to accommodate the larger tires.

Rules 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. (More about tire care in this article.)

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. Manufacturers make a range of tires to meet a general demand.
