Is Wheel Balancing Not Necessary for Rear Wheels?

[DePaisley]

Wheel balancing is required for rear wheels. Below is relevant information about wheel balancing: 1. Reasons for wheel balancing: Vehicle wheel balancing refers to the balance between wheels when the car is in motion. To prevent an unbalanced state caused by uneven mass distribution of various parts during driving, wheel balancing is necessary. 2. Benefits of wheel balancing: Regular balance checks can not only extend the lifespan of car tires but also improve driving stability, avoiding traffic accidents caused by tire wobbling, bouncing, or loss of control during high-speed driving.

The tire shop owner told me this: as long as the wheels are rotating, whether they're front or rear wheels, they all need wheel balancing. Think about it—if the rear wheels are unbalanced, driving on the highway feels like sitting on a massage chair in the back seat. Especially now, with more and more rear-wheel-drive cars, the rear wheels spin even faster than the front ones. Last week, a BMW owner only balanced the front wheels, and after hitting 80 km/h, the trunk started rattling. When we took it off, we found the right rear wheel was off by 30 grams in weight. After the mechanic calibrated it with lead weights, the noise disappeared instantly. Seriously, don’t skimp on those few bucks.

I've been modifying wheels for seven or eight years, and I can tell you for sure that any place with wheels needs balancing. Skipping dynamic balancing on the rear wheels might save you a hundred bucks, but the tire noise will double inside the cabin. The worst part is uneven wear—the outer side wears out twice as fast as the inner side, costing you an extra five hundred per tire. Last week, I helped a fellow car enthusiast check the data: just a 15-gram imbalance in the rear wheels caused wavy wear patterns in just three months. My advice is to get a balance check every time you change tires or after every 20,000 kilometers. Many shops now offer discounts for balancing all four wheels together.

Just experienced rear wheel imbalance: At highway speeds, you can clearly feel the rear seats shaking. Once the speed exceeds 70 km/h, it feels like riding an old-fashioned tractor. The mechanic checked with a diagnostic tool and found the left rear wheel was missing a 20-gram counterweight. He mentioned that modern cars come with ABS sensors, and wheel speed differences can affect the anti-lock braking system's judgment. Especially for electric vehicles with high torque, rear wheel imbalance can damage the differential bearings more severely. He advised against believing the 'rear wheels don’t need balancing' myth, emphasizing that four-wheel balancing is the standard procedure.

From a mechanical principle perspective, all rotating components require dynamic balancing. While rear wheels may appear non-steering, they actually rotate over 2,000 times per minute at high speeds. I once experienced an unbalanced right rear wheel - mineral water bottles in the trunk would roll around on their own, though the dashboard showed no warning. My nephew, an auto repair professional, explained that rear wheel imbalance can cause high-frequency suspension oscillations, which may lead to shock absorber oil leaks. Now I insist on four-wheel balancing during every seasonal tire rotation, because safety should never be compromised.

Car tires are like drum washing machines; any asymmetry is amplified into vibrations when spinning at high speeds. Last month, I replaced the rear tires with AT tires without balancing them, and even the steering wheel started shaking on the national highway. The maintenance manual clearly states: It is recommended to perform dynamic balancing every 8,000 km or after tire repairs. Pay special attention during the season for changing snow tires, as melted snow inside the rims can cause weight imbalance. Don’t cut corners by neglecting the rear tires—the vehicle’s weight balance is an integrated system.
