- Hey, what's up guys, Josh from Trailbuilt,
and there is no doubt that trying to figure out
which size tire will fit on your jeep, truck,
or off road rig can be a bit of a guessing game,
hence by we have a fitment gallery right on our website
but then, there's trying to figure out how to read
all the different sizes as well.
Like P metric, LT metric, or flotation sizes,
and that's why in today's video we're gonna cover
the basics of how to read the different types
of tire sizes and help take some of that guesswork
out of it for you.
Also if you guys are looking to pick up
a new set of wheels and tires, or suspension lift,
make sure and head on over to our website,
it's trailbuiltoffroad.com.
All right guys, before we get started,

Ready, let's go.
If you guys have ever looked at a tire size chart
and thought it was a little overwhelming,
well, that's because it is.
There is a ton of information to break down
when trying to decide on what's the best tire size
to purchase for your own application,
and it can be a real challenge,
and also why we have a gallery on our Trailbuilt website,
made specifically to see what size tire fits,
and what doesn't, and that helps take a lot of that
guess work out of trying to figure it out for yourselves.
But first, we have to understand how to read the tire sizes.
To start, there are two different types of
listed measurements for tire sizes.
One of them is metric, and the other is flotation.
Metric sizes start with a number in millimeters
and there are four different designation
categories for metric sizes.
There's P for passenger, LT for light truck,
then ST for special trailer, then T for temporary tire.
Typically the designation is imprinted before the number,
and if it's not, then most likely it's a passenger tire.
The first number on a metric size is what's known
as the section width of the tire,
or basically the width of the tire,
and is measured from the side wall
to the other side wall in millimeters.
The next number is a percentage of the first number,
and is used to determine the height of the sidewall.
After that the next number is the size of the wheel.
Typically you will see an R that separates the sidewall
height number and the size of the wheel number,
and that'll tell you that is a radial ply constructed tire,
as opposed to it's counterpart the bias ply.
Radial tires are the most common tires
on the market for passenger vehicles,
as their construction allows for a much better ride
compared to the bias ply.
Light truck tires will have additional what are called
plies, or layers, of woven nylon or steel
to construct what is known as the carcass of the tire.
They'll also have a thicker rubber, deeper tread,
and stronger bead bundle.
The more plies or layers there are,
the stronger the tire is, plus,
are capable of holding a higher pressure of air.
All right guys, now that we have
that covered in metric sizes,
flotation sizes are much easier to understand
as their number directly relates to the tire's
measurement in inches.
The first number is the height of the tire in inches,
the second number is the width of the tire in inches,
and the third number the wheel size.
For example, we have a 35 inch by 12.50, 17,
which means the tire is 35 inches tall,
12 and a half inches wide, and fits a 17 inch wheel.
And for the other example for P metric sizes,
this one here is a 285, 60 with a 20 inch wheel
and measures to just about over 32 inches.
Or we also have the calculator link in the bottom
on the footer on our website at trailbuiltoffroad.com
so you can convert those metric sizes
into flotation sizes to know exactly what size tire
is gonna fit on your rig.
All right guys, hopefully this video has helped out
in one way or another, and if you guys are looking for
a new set of tires and wheels,
make sure and head on over to our website,
