Biggest Tire On Stock Toyota Tacoma: PERFECT FIT

What is the biggest tire you can fit on a stock Toyota Tacoma? The biggest tire you can fit without a body or suspension lift and stock Rims are 32.16″ i.e. 275/70/17.

Alternatively, Fitting 33“ tires i.e. 285/70/17 on a stock suspension requires modifications to the front fender liner and rear fender flair.

So there are 3 factors to consider before fitting bigger tires to your stock truck/Ute.

Fender liner clearance
Backspacing / Wheel Offset
Spare wheel clearance

When fitting a bigger tire to the stock Tacoma rims you can get away with a 275/70/17 since it is a narrower tire but still offers improved ground clearance with the 70 profile.

This size is 1 inch taller but the same width as the factory.

What if you want to fit 33” tires on your stock suspension with 0-offset wheel?

What modifications does one need to make them fit?

We discuss all of that in more detail a bit later.

let’s look at what we know so far:

Key Takeaway

275/70/17 or 32.2×10.8R17 on the suspension will fit without any modifications
When fitting 33″ tires the front tire touches slightly on the front fender liner on full lock.
When fitting 33″ tires the front tire also scrubs on the fender flair on full lock.
When fitting 33″ tires there are two pieces of protruding plastic that need to be trimmed away
There is a small bolt on the front fender that secures the liner in place that needs relocation
When fitting 33″ tires the front mudguards need to be removed
33″ tires touch the hangers on the leaf pack on the right side
An aftermarket rim with a zero (0) offset or more negative increases the backspacing for 33″ tires
A 2″-3″ leveling kit will eliminate the need to cut away too much plastic on the wheel fenders
Fitting a 2-3-inch leveling kit combined with a negative offset aftermarket rim will negate the need to cut away fender flairs and other plastic bits

Let’s now look into the modofications and fitment requirement in more detail!

Fender Liner Scrubbing

The front tire touches slightly on the front fender liner on full lock.

So fitting a 33-inch AT tire to a stock 2019 Tacoma with a 0-offset rim pretty much squeezes in, however, it requires some minor modifications to fully clear on full wheel lock.

The front tire touches slightly on the front fender liner on full lock.
The front tire also scrubs on the fender flair on full lock.
These two pieces of protruding plastic can easily be trimmed away
It won’t detract from the aesthetics of the truck.

Fender Liner Trim and Relocate

front fender liners touch slightly on full lock and require some modifications to allow the wheel to turn freely

So as mentioned, both the front driver and passenger sides’ front fender liners touch slightly on full lock and require some modifications to allow the wheel to turn freely.

Simply cutting away the plastic parts neatly ensures total clearance on both the driver and passenger sides.

There is a small bolt on the front fender that secures the liner in place
This bolt requires relocation

33” Spare Wheel Fit

The tires touch the hangers on the leaf pack on the right side.

You can deflate the tire for a more snug fit.

The right side sits against the exhaust.
The heat shield on the exhaust pipe should protect the tire from any heat damage and melting.
The exhaust pipe temperature is the coolest the further away it is from the engine outlet
The chances of it getting hot enough to melt the rubber are slim to none.

Tacoma Biggest Tire with a Leveling Kit

If you decide to go with a 3-inch lift kit to fit bigger tires on your Tacoma you might want to consider a rim upgrade as well.

This will allow you to take full advantage of the increased clearance by fitting a more negative offset rim.

A decent aftermarket rim will be a 0 offset or more and will improve the needed backspacing

A decent aftermarket rim will be a 0 offset or more and will improve the needed backspacing
This allows you to fit a nice 33-inch, or bigger tire without any scrubbing or chaffing against suspension components.
An aftermarket rim will allow you to go 315/70/17 or 12.5 inches.
There will still be a need to trim fender liners and the like to make it fit perfectly.

A popular tire width for 3″ lift kits is 285mm with little drama. This is something like a 285/70/17 or 285/75/16, which is a good choice since it gives you 2″ taller and .8″ wider than the factory.

Biggest Tire on Stock 2015 Tacoma

There are about 4 wheel sizes that will comfortably fit on a stock Tacoma with no lift or suspension upgrades on standard tires.

The biggest tires you can fit on a stock 2015 Tacoma is:

265/75/16
265/70/17
265-65-18
265/75/17 If you remove the mud flaps

With the 17” rim the wheels scrub slightly on the mud flaps when turning in reverse.
Remove them or risk having them ripped off when you reverse.
2016+ Tacoma Options: 265/70/17, 265/75/16 or 265/65/18

Will 33s Fit on my 2017 Tacoma?

Yes, you can fit this size if you want to run 16” in 285/75/16.

Same applies to 17” tires in 285/70/17.

It requires some trimming on the inside fender liners.

The wheel offset on TRD Pro wheels is 4mm.

The TRD Pro rims will cause minor scrub when at full lock, in reverse in an off-camber situation so you will need to trim a bit to maintain full articulation and clearance.
Fitting a slightly more negative offset rim will improve the backspacing clearance, however, some minor wheel arch and body mount trim will still be necessary.

What about a cheap body lift?

Fitting a relatively inexpensive 2-inch leveling kit will allow you to install slightly taller and wider tires.

Note, however, the factory stock shocks/dampers and springs are inadequate for the increased weight of a bigger steel bumper and winch, if you plan on fitting these accessories later on.

For those types of modifications, you’ll need a full suspension kit specifically designed to carry the additional weight.

a body lift will improve clearance, however, this will not give you much advantage when going off-road.

A full suspension upgrade will greatly improve the aesthetics, weight-carrying abilities, and ease of fitting 33-inch tires on your Tacoma.

Even a body lift will improve clearance, however, this will not give you much advantage when going off-road.
Body lifts will improve your truck aesthetics.
