Original Tacoma Tire Sizes – From 1995 to 2011
Thinking about new tires? Wondering what sizes are available that will fit your Tacoma? Maybe we can help.
Toyota offered quite a few different sizes on each Tacomas made between 1995 and 2010, with different rim sizes (from 14″ to 18″) and different bolt patterns (either 5 lug or 6 lug). Here’s a quick break-down:
OEM Tacoma Tire Sizes
Model Year Original Factory Tacoma Tire Sizes Sorted By Rim Size
1995-2000 195/75 R14 215/70 R14 225/75 R15 31×10.5 R15 265/70 R16
2001-2004 205/75 R15 225/75 R15 235/55 R16 265/70 R16 -
2005-2011 215/70 R15 245/75 R16 265/70 R16 265/65 R17 255/45 R18
As you can see from the table above, there’s been a pretty dramatic increase in tire and rim sizes over the years. In the mid-90′s, it wasn’t uncommon to see a Tacoma with 14″ rims. Today, it’s hard to find any new vehicle with 14″ rims, let alone a pickup truck.
The wheel and tire sizes above range from fairly small (as little as 7.7 inches wide by 25.5 inches tall) to decently beefy (10.4 inches in width by 30.6 inches in height).
What Lug Pattern Is On My Tacoma?
Do you have a PreRunner or a 4×4 Tacoma? If the answer is yes (learn what a Tacoma PreRunner is here), then you have a 6-lug wheel. Of all the tire and wheel sizes listed in the table above, 6-lug wheels will be bigger. 5-lug wheels are only available on base-model Tacomas, and they generally come with 14″ or 15″ wheels.
How Big Can I Go?
Many Tacoma owners want to know how big they can go on their trucks without modification. Here are some good rules of thumb:
1. For 2005+ Tacomas, you can pick from any OEM size on the list. Technically, the largest OEM tire and wheel size for your model year will fit on your truck without any modification…but that doesn’t mean that changing your 05′ Tacoma from a 215/70R15 to a 265/70R16 is a good idea. That’s a pretty dramatic difference in tire-size (nearly 4″ taller) which can cause problems:
Speedometer and odometer errors are going to be pronounced when you increase tire size by more than an inch or so in height
You lose low-end torque when you add bigger wheels. By increasing the overall diameter of your drive wheels, you effectively reduce your rear axle ratio…which means slower acceleration.
2. You can increase tire height and width 3% each without installing a lift or leveling kit. You can usually get away with using tires that are 3% larger than the tires you’re replacing…which means about 1″ of additional tire height and .3″ additional width on most trucks. Tire dealers often call this a “plus 1″ tire size increase, and it’s often a reasonable option for truck owners who want a little more tire without any sort of modification.
Keep in mind that you can’t always find a tire that’s exactly 3% larger than the factory size – you may not be able to go any bigger in some cases.
3. You can add 1″ inch of tire height for every 1″ of ride lift. If you go with a 3″ lift-leveling kit on your 2005+ Tacoma that means you can fit tires as tall 33.5″. HOWEVER, width is a concern as well. The widest factory tire on any Tacoma since 1995 is 10.43″ – if you can’t match this width (10.75″ max) you’ll need to buy new rims with different backspacing.
The bottom line is that you can’t always find tires that match both your width and height requirements.
Suggested 2005 and Up Over-Sized Tacoma Tires
NOTE: All of these sizes are based on using factory wheels. If you upgrade wheels, you can easily go with a wider tire…but if you go really wide (larger than 285) you might want to invest in some fender flares.
NO LIFT KIT
Max tire size for 16″ rims: 265/75 R16 – one inch taller but same width as factory.
Max tire size for 17″ rims: 265/70 R17 – one inch taller but same width as factory.
2″ LEVELING KIT (or smaller)
If you install a leveling kit, you may be able to shoe-horn some wider tires under your Tacoma than what we have listed here. If so, expect to do some trimming – and be sure to post your experience in the comments below.
Max tire size for 16″ rims: 265/75 R16 – one inch taller but same width as factory. You could fit a 275/75R16 tire, but no one makes them.
Max tire size for 17″ rims: 275/70 R17 – 1.5 inches taller and 0.4″ wider than factory.
3″ LIFT KIT
Note: If you’re planning on a 3″ lift, you almost have to go with either a new set of wheels OR some wheel spacers. There just aren’t any common tire sizes that can take advantage of your lift and still fit your stock rims.
If you go with a set of after-market rims designed for the Tacoma (which means they have the right amount of backspacing to accommodate a much wider tire), you can go as large as 315mm in width – about 12.5″. However, at this width you may have to do some trimming of the fenders and the plastic wheel wells so that tires don’t rub during turns. This also applies if you install some 1.5″ spacers, only wheel spacers can be problematic.
A more common tire width for Tacomas with a 3″ lift kit is 285 mm. For 17″ wheels, 285/70R17′s are more than 2″ taller than the largest stock Tacoma tire as well as .8″ wider. For 16″ wheels, 285/75R16′s offer similar dimensions.
