How Can You Tell if Your New Tires are the Best Match for Your Wheels?

This is a regular query from motorists who want to improve the aesthetics of their wheels without changing the tires or the performance of their cars.

The wisest (and safest) course of action when pursuing a wheel upgrade for aesthetic reasons is to keep the standard wheel specifications, which entails preserving both wheel width and diameter.

Your stock tires will fit your new rims well if these wheel requirements are maintained.

Your factory tires will no longer fit the rims if you modify the rim width or diameter, such as going from a 17″ wheel to an 18″ wheel diameter.

How To Read Wheel Sizes?

Reviewing your tire size information is the simplest way to find out the diameter of the stock car wheels, also known as wheel height.

The last number on the label indicating your tire size shows the wheel size. For instance, a 225R70/17 tire size, 17 indicates the wheel diameter. Knowing the wheel width is a little bit complicated, and in most cases, a dealership store is frequently the most reliable source for knowing your wheel width size.

The tire width can also hint at how wide your wheel is. The first number on the tire size label always indicates the width. For instance, if you have a 225R70/17 tire, its width is 225 millimeters. However, you must note that tire width is not reliable for determining the wheel width. This is because a tire of a given width can be fitted on different rims with different widths. For instance, a 225 tire can be fitted on an 8-inch, 8.5-inch, or 11-inch rim.

What Happens if You Install a Tire That is Too Wide for the Rim?

The proportion of tire section width to rim width is significant. If you install tires that are too narrow for the rims, the tires might rip away if you drive at high speeds. On the other hand, if you fit your tires on rims that are too narrow for them, they will bulge in the cross-section.

Are Wider Rims Better?

Wider tires offer enhanced support to the tires and allow you to lower the tire pressure. However, rolling resistance (and wheel weight) rise as rim and tire widths do, but it has been discovered that 30mm-wide rims offer an excellent middle ground for most riders.

Final Take

12.5 tires mounted on 8-inch rims are a fantastic choice for light trucks and off-road vehicles. Performance, durability, and load capacity are all well-balanced by the combination. The tread pattern is made to be quieter and to offer superior traction on a variety of surfaces. Additionally, the tires have strong handling qualities that make it possible to drive with assurance in a variety of road and weather conditions.
