What is the difference between AT22 and AT25?
3 Answers
The differences between Dunlop AT22 and AT25 tires are as follows: 1. Quality difference: Dunlop AT25 tires have better quality, are more wear-resistant, and have a longer service life; Dunlop AT22 tires have relatively lower quality, slightly inferior wear resistance, and produce more noise. 2. Design difference: Dunlop AT22 tires feature larger tread patterns, making them off-road tires with thicker treads, providing better performance in muddy terrain; whereas Dunlop AT25 tires have simpler, regular groove patterns on the tread, with a more reasonable design that enhances durability and wear resistance. 3. Fuel consumption difference: Dunlop AT22 tires consume more fuel due to their coarser and wider tread patterns, which offer greater grip but at the cost of higher fuel consumption; Dunlop AT25 tires, on the other hand, have lower fuel consumption, making them more economical for urban road driving.
As a veteran driver with over a decade of experience, let me explain the difference between AT22 and AT25. These primarily differ in automatic transmission fluid types. AT22 has lower viscosity, providing smoother operation in city traffic jams, better fuel efficiency, and quicker cold starts in winter. AT25 has higher viscosity, making it more suitable for highway driving or frequent heavy-load situations, as it better protects internal transmission gears from wear. But don't switch arbitrarily - always consult your vehicle manual. Once I mistakenly used AT22 in an old SUV during hot weather, which caused increased transmission noise until I promptly switched back to AT25. General recommendation: Use AT22 for daily commuting vehicles, and AT25 for frequent highway or off-road driving - it's both worry-free and fuel-efficient.
As a professional auto mechanic, I must remind everyone that AT22 and AT25 are no trivial matters. AT22 has a thinner molecular design, flows faster, and is suitable for lubricating compact car automatic transmissions, reducing friction; AT25 is more viscous, providing stronger protection for high-power engines or high-temperature environments, commonly used in trucks and SUVs. But choosing the wrong one can be disastrous—I've dealt with cases where owners mistakenly used AT25 in regular cars, leading to seal leaks and pump pressure drops, which were time-consuming to repair. So always check the specification in your car's manual, don't just buy the cheapest option blindly, as it could shorten your vehicle's lifespan—what a loss that would be!
