Do you want to get new rims for your 12.5 tires but don’t know which rim size will best fit your tires? If so, you might be wondering, “how wide of a rim for 12.5 tires” just like other people.
You don’t need to worry; here in this resourceful guide, I provide all the necessary detailed information for you to solve this problem.
Rim width is one of the most crucial points to consider for new rims to adjust with your tires. This guide will help you understand the necessary aspects that you must consider before choosing new rims.
In addition, a rim width tire size chart is also included in the following parts. It will help you know the recommended rim widths for different tire sizes. So, dig through the whole content for further details.
Things to Consider for New Rims?
There are several important aspects you should consider whenever you want to have new rims. Tire size, wheel diameter, materials, offset, rim width and other things play a crucial role in picking the right rims.
In addition, consider the following things for your new rims; we are certain you will have great rims to perfectly fit your tires.
Tire size
First, consider the tire size you are looking for new rims. A quick chart of tire sizes and their recommended rim widths are given below to make this choice super easy for you. You should follow this formula, a perfect rim size is always less than half of your desired tire’s overall diameter.
Wheel Diameter
Wheel diameter is the next important thing that you must consider to get the right rim size. The larger the wheel diameter is, the costlier the tire and wheel will be.
Choose a rim size that is less than half of your tire’s overall diameter. For example, if your tire’s overall diameter is 37″, a 16 or 17-inch rim size is a perfect match for your tire.
Material
Wheel material is another key point to consider whenever you want new rims. You can choose either stainless steel or alloy wheels to get maximum durability and optimal performance for your vehicle.
Wheel weight also depends mostly on its material and on its size as well. So, pick the rim material to get the best performance out of it.
Rim Width
Another important feature that you must consider is the rim width for choosing new wheels. Rim width plays the most important role in fitting your tire into new wheels.
If a 7.5″ wheel’s rim width is bigger than 235 millimetres then it won’t fit your stock tires. Every tire is constructed to match its recommended rim width. That’s why picking a wheel with less or greater than 2-3 inches of your tire is a smart choice.
Wheel Offset
The offset of a wheel is the gap between its assembling surface and its centerline. Backspacing, on the contrary, refers to the separation between the mounting surface and the back lip of the wheel.
However, positive offset rims make it possible to insert wider tires without having them emerging from the wheel. Positive offset wheels are frequently used by 4×4 users to prevent clearance problems.
Bolt Pattern
The bolt pattern is another must-consider feature to have a perfect fit wheel for your vehicle. In some cases, adapters can transform the bolt pattern, but you must make sure it fits your axle’s bolt design.
For example, new JKs come with a 5(the lugs numbers)-on-5(bolt circle’s diameter in inches) bolt design, while on the contrary, older XJs and TJs come with bolt pattern 5-on-4.5.
Backspacing
Many people think that wheel offset and backspacing are the same thing. But for your kind information, backspacing refers to the gap between the back lip and the mounting surface of the wheel.
On the other hand, wheel offset refers to the separation between the centre line and the assembly point of the wheel.
Both term offset and backspacing are almost similar to each other. However, a deep backspacing is similar to a positive offset, while shallow backspacing is similar to a negative offset.
Bead Seat
The Bead Seat of a rim/wheel is another key point to consider for having new rims for your stock tires. Wheel bead seat aid with perfect air pressure and helps to ensure your tires are perfectly seating on the wheel without failure.
In addition, the plus point of the bead seat is “taller and wider seat bead lets you air down your tires without removing them from the wheels.” Securing bolt clamps of beadlock wheels keeps your tires mounting even with zero air pressure.
Center Bore
You should consider the center bore, which refers to the wheel’s center hole. Your wheel’s bolt pattern is connected to its size. For example, if the bolt pattern is smaller, the center bore will be small as well. On the contrary, if the bolt pattern is large, then the center bore will be larger too.
The Center bore plays a crucial role during attaching to full floating axles and over-locking hubs. Hub centric wheel uses a center bore to install on the axle, while the lug-centric wheel uses lug nuts to install on the wheel.
Load Rating
The last thing to consider for having new rims is the wheel’s load rating. Wheels/rims come with load ratings, and the bolt pattern and wheel’s construction play an important role in determining load ratings.
When contrasting to cast aluminium wheels, steel wheels are often evaluated at lower loads. On the other hand, forged wheels have the greatest load ratings.
A wheel’s design will have a higher load rating if it has a larger bolt circle and additional lug nuts. It helps to distribute the loads evenly for better balance.
