Methods to determine if a tire is underinflated include: 1. Visually inspect if any of the four tires appears noticeably flat. 2. Use a tire pressure measurement device, such as a handheld tire pressure monitor or an onboard automatic tire pressure display, to accurately measure the tire pressure. 3. Install a tire pressure monitoring system to continuously monitor the tire pressure. Here are the effects of underinflated tires: 1. Damage to the tire sidewall and inner edge: Damage to the inner edge of the tire is usually caused by improper operation during mounting or dismounting the tire from the wheel rim. This often occurs during the installation of new tires or after tire repairs. Damage to the sidewall and inner edge can lead to slow leaks and a high risk of tire blowouts. 2. Foreign objects puncturing the tire: Punctures from foreign objects are the most common type of tire damage. Objects that easily puncture tires include nails, screws, wires, glass shards, sharp stones, and ceramic fragments. Among these, nails and screws are the most likely to puncture the tire, causing slow leaks. If left unaddressed, these objects can worsen the damage to the tire. 3. Deformation of the wheel rim flange: When a car tire is fully inflated, the outer edge of the tire tightly seals against the wheel rim flange to prevent gas leakage. If the wheel rim flange is deformed due to impact, it can compromise the seal with the tire's outer edge, leading to slow leaks.

Is the Corolla based on the TNGA architecture?

Corolla is based on the TNGA architecture, which is similar to Volkswagen's MQB and MLB modular platforms, but these are not identical concepts. This architecture represents an upgrade in the overall system capabilities. The Corolla is a compact sedan launched by FAW Toyota. The new-generation Corolla is built on the all-new TNGA architecture, achieving overall vehicle lightweighting. In terms of the car's exterior and interior, the vehicle's quality has significantly improved, with a more youthful overall design. The TNGA architecture lowers the center of gravity of the new Corolla. For the hybrid version, the battery is relocated beneath the rear seats, which not only enhances driving stability but also increases interior space. Built on the new platform, the Corolla also features upgraded suspension. The front suspension's eccentric pressure bearing aligns with the kingpin, effectively improving steering precision and enhancing the durability of the eccentric pressure bearing.

How to Adjust a Slightly Misaligned Steering Wheel?

First, measure the tire pressure on both sides. When the tire pressure is inconsistent, the vehicle will tend to drive towards the side with lower pressure. If there are no issues with the tires, check the condition of the chassis components. Changes in the four-wheel alignment values can also cause the steering wheel to become misaligned after some time of use. When the tie rod is at the front, if the steering wheel is tilted to the left, extend the left tie rod outward and shorten the right one inward. Conversely, if the steering wheel is tilted to the right, do the opposite. The same applies vice versa. If the issue persists, you can first straighten the steering wheel, keep the wheels stationary, remove the steering wheel, adjust its position manually, and then tighten the steering wheel screws.
