Why does the steering wheel feel heavy after switching to summer tires?

[GageDella]

It may be due to insufficient tire pressure. Underinflated tires can affect the steering wheel's heaviness, and in severe cases, may even lead to the risk of a tire blowout. A heavy steering wheel is a common issue and does not necessarily indicate a problem with the car's quality. Car owners should accumulate more knowledge about common car maintenance to handle such situations correctly. Here is some additional information: 1. Electro-hydraulic power steering. The electro-hydraulic power steering system is an upgraded version of the purely mechanical hydraulic power steering. Originally, it used an oil pump to provide assistance, making steering easier for the driver. 2. Issues with steering fluid. In such power steering systems, the feeling of steering heaviness is usually relatively constant. If it suddenly becomes very heavy one day or gradually becomes heavier, it could be due to dirty steering fluid, which, like engine oil, needs to be replaced.
