Does having different tire tread patterns have any impact?

Replacing two tires with different tread patterns can affect the vehicle, and in severe cases, may lead to loss of control. Here is some relevant information about tires: 1. Main materials of tires: The primary material of tires is rubber, which has the characteristic of aging over time or after prolonged storage, leading to significant changes in the tire's physical properties such as hardness and wear resistance. If an aged tire continues to be used, it may lightly affect vehicle performance or, in severe cases, result in a blowout. 2. Tire lifespan: Generally, all-season or economy tires have a lifespan of 3-5 years, with a mileage of about 50,000 kilometers. Under normal circumstances, a tire's lifespan from the date of manufacture is sufficient for one year of use. However, for high-performance tires, the lifespan is only 20,000 to 30,000 kilometers. If the price is reduced, it may also be worth considering purchasing them.
Changing to tires with different tread patterns can indeed have an impact. I learned this the hard way when I last replaced my tires. Different tread patterns are designed for different purposes—some focus on water drainage, others on noise reduction, and some enhance grip. The most noticeable effect after mixing treads was a decline in the vehicle's driving quality. During high-speed cornering, the inconsistent grip between the left and right wheels caused slight body sway, and braking distances were significantly longer in the rain. I recommend using tires with the same tread pattern at least on the same axle, and if possible, replacing all four tires together. Additionally, a tread depth difference exceeding 3 mm can affect directional stability, and in severe cases, it may trigger frequent intervention from the ESP system. Don't cut corners when it comes to tire replacement—it's best to replace them as a complete set with matching tires.
Mixing tire tread patterns requires caution, as I always pay close attention to these details when driving. Different brands have varying rubber compounds, with distinct wear resistance indices and heat generation coefficients, which may lead to uneven tire wear. Inconsistent tread patterns can also increase tire noise, especially noticeable as a humming sound above 60 km/h. More critically, it affects the four-wheel alignment parameters, potentially causing uneven wear on the suspension system over time. I recommend checking not only the consistency of tread patterns but also ensuring the tire speed rating and load index are the same when inspecting tires. The safest approach is to replace all tires with the same specification and tread pattern, rather than compromising safety to save a few hundred dollars.
Using tires with inconsistent tread patterns during replacement definitely has negative effects. I frequently encounter such cases in repair shops. The most immediate danger is the difference in water drainage efficiency during rain, especially when driving at high speeds through waterlogged areas. Uneven grip between the two sides can easily cause the vehicle to skid. This becomes more pronounced in winter, where variations in snow traction performance between different tread patterns may lead to loss of vehicle control. Additionally, differences in tread groove depth can affect braking distance—tests show that a mere 2mm difference between left and right tires can increase the braking distance by over half a meter from 100km/h. When replacing tires, it's crucial to ensure that tires on the same axle share identical tread patterns, as this is the most fundamental vehicle safety requirement.
