Understanding the Potenza S001 RFT

First off, what does all that mumbo-jumbo in the name even mean? Let's decode it: "Potenza" is Bridgestone's high-performance tire line, promising a sporty driving experience. "S001" is the specific model within that line, known for its balance of performance and comfort. "RFT" stands for Run-Flat Tire, a crucial feature we'll get into shortly. The "245/40RF19 94W" is the tire size and load/speed rating. Here’s the breakdown:

• 245: This is the tire's section width in millimeters. Basically, how wide the tire is.
