You can fit 12.5 tires on 7.5 rims by using a tire rim adapter. A tire rim adapter is a device that allows you to change the size of your tires without having to replace your entire wheel. This can be a great way to save money and time when you need to change the size of your tires.
- You will need to purchase 12
- 5 tires and 7
- 5 rims
- Once you have the tires and rims, you will need to mount the tires on the rims
- To do this, you will need to place the rim on the ground with the tire next to it
- Take one side of the tire and line it up with one side of the rim
- Once both sides are lined up, push down on the tire until it is fully seated on the rim
- Repeat this process for all four tires
Widest Tire on 18 7.5” Rim
One of the most frequently asked questions we get here at Tire Rack is “what is the widest tire I can fit on my car?” While there isn’t always a definitive answer, our experts have come up with some general guidelines to help you choose the right sized tire for your car.
When it comes to tires, width is measured in millimeters (mm).
The first number in a tire size is the width of the tire from sidewall to sidewall. For example, a 225/45R17 tire has a width of 225 mm.
The second number in a tire size is called the aspect ratio.
This is the height of the sidewall expressed as a percentage of the width. In our example above, the 45 means that the height of the sidewall is 45% of 225 mm, or 101.25 mm. The smaller the aspect ratio,the shorter and wider the sidewall will be.
The last letter in a tire size indicates what type of vehicle the tire was designed for. In our example, R means Radial construction (99% of all passenger car tires are radial). Other letters include B (for bias-ply construction) and D (for diagonal construction).
Now that we know how to read a tire size, let’s talk about what sizes are available and what applications they’re best suited for.
Passenger cars can accommodate tires anywhere from 175 mm wide up to 275 mm wide…and sometimes even wider! As you might expect, wider tires offer more grip than narrow ones but they also tend to be more expensive and may not fit under your fender without some modifications.

How Wide of a Tire Can I Put on a 7.5 Rim?
The width of a tire that can be safely used on a 7.5-inch rim depends on the width of the rim and the width of the tire. For example, a 225/45R17 tire has a section width of 9 inches and an overall diameter of 26 inches. The section width is the measurement from one sidewall to the other, not including the tread.
The overall diameter is the distance from one sidewall to the opposite sidewall, including the tread.
The rule of thumb is that you do not want to exceed a 10% difference between the section width and overall diameter when changing tires. In our example, that would mean not exceeding a 9-inch wide tire on our 7.5-inch wide rim (0.9 x 7.5 = 6.75).
However, it is always best to consult with your local Tire Shop or Automotive Service Professional to get their expert opinion before making any changes to your vehicle’s tires or wheels.
How Wide of a Rim Do You Need for a 12.5 Tire?
A 12.5″ tire is most commonly used on ATVs and UTVs. The width of the rim you need depends on the width of the tire. A wider tire will need a wider rim to support it properly.
For a 12.5″ wide tire, you’ll need at least a 10″ wide rim. However, if you’re running an aggressive tread pattern or are using your vehicle for off-road purposes, you may want to consider going up to an 11″ or 12″ wide rim. This will provide more stability and support for your tires, preventing them from being damaged by rocks or other debris on the trail.
Can You Put a 12.5 Wide Tire on a 9.5 Wide Rim?
It’s possible to put a 12.5 wide tire on a 9.5 wide rim, but it’s not recommended. The reason is that the wider tire will cause the tire to sit outwards from the rim, and this can lead to problems with the bead of the tire staying seated on the rim. Additionally, the extra width of the tire can put stress on the sidewalls of the tires and cause them to bulge outwards.
If you must put a wider tire on a narrower rim, make sure to use caution and check your tires frequently to ensure that they’re still seated properly on the rims.
Can You Put a 12.5 Inch Tire on a 8 Inch Rim?
It’s possible to put a 12.5 inch tire on an 8 inch rim, but it’s not recommended. The reason is that the larger tire will stick out past the edge of the rim, and this can cause problems with the tire being able to grip the road properly. Additionally, the extra weight of the larger tire can put stress on the rim which could cause it to break.

Conclusion
You can fit 12.5 tires on 7.5 rims by using a spacer. A spacer is an adapter that goes between the wheel and the tire to create more space. This will allow you to fit a wider tire on a narrower rim.
spacers come in different sizes, so you will need to measure the width of your rim and the width of your tire before ordering one.
