Stop guessing. Start with the placard.

Most beginner drivers grab whatever tire the seller recommends or try to match a worn sidewall code. That's how you end up with rubbing, speedometer drift, and return hassles.

This ebook flips the script: start with the driver door-jamb tire placard—the manufacturer's official fitment spec—then decode the sidewall, verify every number, and buy with confidence.
