Low-profile rims and tires upgrade the looks of your vehicle and typically rate higher in performance. The biggest issues most drivers have with these style rims and tires are the uncomfortable ride and the price tag attached to replacing these tires. Low-profile tires are typically 30 to 50 per cent higher in cost than conventional tires. This, over the life of the vehicle, can lead to a substantial amount of money. Thankfully, you can convert back to conventional rims and tires.

Look inside the drivers door jamb an locate the information plaque. This is the sticker that contains the VIN, factory tire size, paint colour code and other vehicle-specific information.
Read the tire size from the plaque. For example, the size will appear as: "225/60R16." The first number is the tire width, in millimetres. The second is the sidewall height, relative to the width. The final number is the original rim diameter in inches. Make note of the sizes taken from this plaque.
Read the tire load and speed rating from the plaque. It will be listed directly after the tire size; for example: "92S." The number is the load rating and the letter is the speed rating. Make note of these ratings.
Multiply the tyre's width measurement by 0.03937007874 to convert to inches. For example, 225/60R16 is 8.85-inches (225 X 0.03937007874).
Round the section width, in inches, down to the closest number in 0.5-inch increments. This gives you the correct rim width. In the example, the rim width needed would be 8.5 inches.
Determine the rim diameter by reading the last number on the tire size.
Take this information to a local tire and rim retailer.
Locate a group of tires that match the size the vehicle requires.
Reduce the selected group of tires to match the speed rating and load rating required by the vehicle. The load rating can be higher than recommended if the correct rating is unavailable.
