245/40R18 Tires in Sacramento
The 245/40R18 is an ultra-low-profile performance size, built around a short 3.86" sidewall wrapped on a large 18" wheel. That short sidewall is what gives cars on this size their sharp, immediate steering — but it also means there's very little rubber between your 18" rim and a Sacramento pothole. At roughly 25.7" tall, it's a size you'll find on sport sedans, coupes, and performance trims.
What 245/40R18 Means
Every number on the sidewall describes a real dimension. Here is exactly what the 245/40R18 works out to:
Expect sharp turn-in and strong grip, a firmer ride, and more vulnerability to pothole and curb damage — keep an eye on pressures and consider road-hazard coverage.
