Can 40 tires be replaced with 45?

[SanLila]

Yes, but the sidewall thickness of the tire will increase. Here are the relevant details: 1. Check for surface cracks: Vehicle tires are generally recommended to be replaced every 50,000 to 80,000 kilometers. As long as there are no obvious cracks or signs of aging on the tire surface, you can check the distance between the wear indicators in the main tread grooves and the wear layer. There are also triangular wear indicators on the crown of the tire. If the wear level is almost flush with the wear indicators in the tread grooves or the wear indicators on the crown, it means the tires need to be replaced. 2. Choose durable tires: If you want tires with better durability and handling, consider Pirelli, Goodyear, or Bridgestone. For tires with better overall performance, consider Continental or Michelin. Continental and Michelin use silica additives, which provide better comfort and noise reduction.
