Custom car wheels:

Discover how to select the correct bigger custom car wheels and tires.

While bigger wheels look great on many vehicles, there are some important considerations to make the upgrade to large custom made wheels correctly.

When you change to bigger diameter custom wheels, you will also need to install new tires corresponding to the wheel size (e.g., 17-, 18-, 19- or 20-inch). However, to avoid clearance and performance problems, the outer diameter of the new tires should remain roughly the same as the diameter of the original equipment tires.

This will mean selecting new tires with a narrower or lower sidewall. A lower tire sidewall will offer the positive advantages of quicker steering response and improved handling. They will also give most vehicles a noticeably firmer ride.

What you should know about upsizing your custom wheels and tires:

Bigger wheels add visual appeal to many vehicles. This is especially true on light trucks and SUVs.

Bigger custom made wheels can also contribute to better handling when used with lower profile tires. By properly sizing bigger wheels and matching tires, vehicle performance and speedometer accuracy will be unchanged.

Select the wrong sizes, though, and acceleration and pulling power can be negatively affected, plus they may not clear your vehicle’s bodywork, especially over bumps and hard turns.

How to select bigger custom car wheels; do it right with these important tips:

Backspacing (inboard or outboard positioning of the wheel in the wheelwell) is important for tire clearance and suspension movement.

  1. Most wheel and tire dealers have books that list the largest wheel and tire combination that will fit your vehicle. It’s usually safe to use the Plus One (one inch larger diameter wheel with a lower profile tire) and Plus Two method (two inch larger diameter wheel with a tire that is two series lower in profile).
  2. Try to maintain the same backspacing as your original wheels. That is the distance from the inside wheel flange to the edge of the rim. If you are installing a one inch wider wheel, add 1/2-inch more of backspacing and 1/2-inch more to the front side offset. Mount only one tire and install this wheel and tire on the vehicle to physically check for clearance problems.
  3. Some trucks and SUVs require higher profile tires (taller sidewalls) as well as larger diameter wheels to properly fill the wheel-wells for that perfect look. You may have to recalibrate your speedometer to compensate for the larger diameter wheel and tire combination.

Make sure you have the correct length lug nuts for your custom wheels. Also make sure the seat of the lug nut is appropriate for the wheel. When you tighten your custom car wheels, check to see if the lug nuts are bottoming out before the wheel is being tightened. Always re-torque your custom wheels after a few miles of driving as they may loosen up as the wheels and lugs seat.
