Is a 45 tire too thin?

[VonBethany]

45 tires are not too thin. Here are the specific details: 1. Performance: 45 tires have a small aspect ratio, thicker tires, smaller rims, and narrower treads, which do not affect the tire's lifespan and reduce the risk of blowouts. They offer strong grip, better steering, wet performance, noise reduction, and wear resistance. Comfort is improved; performance at low to medium speeds is better, and the narrower tires reduce rolling resistance, leading to lower fuel consumption. 2. Inspection and protection: Check the tires, especially the tread grooves. Tires have circular grooves and raised wear indicators. If the tread wear level matches the raised indicators, the tire needs replacement. Use a tread depth gauge to measure wear. The gauge has red, yellow, and green indicators. Press the gauge against the bottom of the tread to check the color: green means good, yellow is critical, and red indicates replacement. For gauges without color indicators, check the scale—if the tread depth is 1.6 mm or less, replace the tire. If the tire shows bulging or deformation, or if the internal metal cords are damaged or broken, there is a risk of blowout, and the tire should be replaced immediately.
