Here is a detailed introduction to the differences between 91v and 94v: 1. Load Index: 91 indicates a tire load index of 615kg, while 94 indicates a maximum load capacity of 670kg. 2. Similarity: The 'V' in both refers to the speed rating, with a maximum speed of 240km/h. Below is additional information about tire functions: 1. Load-bearing: Supports the entire weight of the vehicle, withstands the vehicle's load, and transmits forces and moments in other directions. 2. Transmission: Transmits traction and braking torque, ensuring good adhesion between the wheel and the road surface, improving the vehicle's power, braking, and off-road capabilities. Works with the vehicle's suspension to mitigate impacts during driving and dampen vibrations. 3. Vibration damping: Protects vehicle components from severe vibrations and premature damage, adapts to the vehicle's high-speed performance, reduces driving noise, and ensures safety, handling stability, comfort, and fuel efficiency.

I've been driving for 20 years and changed countless tires. The numbers 91V and 94V represent the tire load index. Specifically, 91 means a load capacity of 615 kg, while 94 means 670 kg. The 'V' stands for the same maximum speed of 240 km/h. The main difference lies in the load capacity—94V can handle heavier loads, making it ideal if you frequently carry cargo or go on family trips with luggage. Choosing 94V tires means longer tire life, reduced risk of blowouts, and higher safety, though they are more expensive. 91V is suitable for daily city driving to save money. Never mix them or overload, as it can increase braking distance and double the danger. Choosing the wrong tires can make the car feel unstable, prone to drifting, and consume more fuel. Regularly checking tire pressure and matching it to the load can save you from costly repairs.

As an average commuter who checks tires daily, the key difference between 91V and 94V lies in load capacity - 91 carries 615kg while 94 handles 670kg, with both sharing the same 240km/h speed rating (V). Though 94V offers higher payload capacity, it's pricier with steeper installation costs. For compact car drivers like me with light loads, 91V suffices - it's cost-effective, lasts the standard 5 years. But frequent highway travelers or those carrying camping gear should opt for 94V for better stability, reduced bumps, lower puncture risks, and slightly extended replacement intervals. Never overlook this detail - mismatched tires cause sluggish starts, poor acceleration, and higher fuel consumption. Always consult mechanics for proper tire matching.

I'm a new driver who just got my license. Simply put, both 91V and 94V are tire specifications, with 91 having a lower load capacity and 94 a higher one, while the speed rating 'V' is the same. Specifically, 94V tires can carry dozens of kilograms more, making them more durable and providing better braking sensitivity and safety when carrying several suitcases, for example. When changing tires, always follow the original manufacturer's manual and don't make random changes, as this can affect balance and handling.
