When it comes to wheel and tire upgrades, it’s never a straightforward answer as it depends on several factors, such as the width of the rim, the aspect ratio of the tire, and the overall diameter of the tire. In this article, we will explore the factors that determine the maximum tire size for a 17-inch rim and provide some guidelines to help you make an informed decision when upgrading your vehicle’s wheels.
The biggest tire you can fit on a 17-inch rim is 54X19.50R17 which has a Diameter of 54.0″
And a Width of 19.5″. The Sidewall is 18.5″ and it has a rolling circumference of 169.6″
larger tires simply look amazing on almost any 4WD and greatly improve the aesthetics of your vehicle. There’s also the added offroad benefit of improved traction and ground clearance.
Remember, exceeding the manufacturer’s recommended tire size can have serious safety and handling side-effects on your vehicle. We do these upgrades at our own risk.

Can You Put 35 Inch Tires On 17-Inch Rims?

Can You Put Any Size Tire On A 17-Inch Rim?
No, the maximum tire size depends on factors such as rim width, diameter, and the maximum offset for the vehicle.
What Size Tire Is Best For 17inch Rims?
This largely depends on the vehicle you are driving. For a stock Jeep, for example, a 285/70/17 or 33-inch tyre works well in a range of conditions with minimal modifications.
What Size Tire Is A 33 On A 17-Inch Rim?
A 33-inch tire is usually between a 285/70/17 to 295/70/17.
Are 285 Tires The Same As 33?
285 wide tires are the same as 33” tires although 285 is the tread width in millimetres and 33″ is the tire diameter. 285/75/16 is usually the accepted metric equivalent size for 33’s.
When comparing a 33” tire to a 285 wide tire, you are essentially talking about two completely different measurements. The 33” refers to the width of the tire (285) multiplied by the height percentage of the sidewall (75), in millimetres, x2 because there are two sidewalls, divided by 25.4 (inches) plus the wheel size in inches (16”).
Phew!!! That’s a mouthful and a lot to digest at once so let’s break it down into a simple formula. Click the link below for more detail.
35×12.5R17 vs 315/70R17 – SIZE/WEIGHT/HEIGHT/LOAD Difference
Understanding tire measurements can be very tricky and complicated, especially when tires are similar in size but described using different measurements. There is the metric measurement and the imperial or standard measurements and these can become confusing very quickly. So what is the main difference between 35×12.5R17 vs 315/70R17 tire?
The 35” tire represents the overall combined width (mm), aspect ratio (%), and wheel diameter (inches) measurement. The 315 tire measurement is a metric value and only represents the tire width which is measured in millimetres.
The two sizes are almost the same but vary somewhat between tire models and brands. Let’s find out what the exact differences are between the two when it comes to size, weight, height, and load ratings.

Biggest tire – well, the tallest is the Toyo Open Country M/T 34.1 ” LT285/75/17…that doesnt mean it will fit your stock wheel well without leveling and some trimming. I think most LT285/70/17’s will fit with a leveling kit

I have a 2″ RC level on mine with BFG AT 285/70/17. I wouldn’t go any bigger than that. This size tires fills the wheel well very well, any bigger and your probably looking at some trimming. Plus the stock wheel is only 7.5″ wide. I believe that 285 is the max for that size wheel.

The tallest seems to be ~33-34″. 285/70R17 would be the biggest I would run personally. It is likely the biggest that will fit without any issues – though actual measured size may vary between tire manufacturers.
