Choosing the right tire size for your vehicle is essential for safety, comfort, and performance — and in Southern California, where driving conditions vary from sunny highways to coastal roads, it’s even more important. This Tire Size Guide provides you with an easy way to understand which tire sizes fit the most common cars in the region, how to find your correct size, and how to make a confident tire purchase. Whether you drive a Honda Civic in San Diego or a Tesla in Riverside, this guide simplifies the process and helps you get on the road safely and efficiently.
Why Tire Size Matters
Tire size affects everything from your fuel efficiency and handling to your car’s alignment and braking. Driving on the wrong size can lead to uneven wear, reduced traction, and even damage to your suspension system. That’s why every driver in Southern California should take the time to check their tire size — especially before buying replacements or upgrading wheels.
How to Read a Tire Size
Tire sizes are printed on the sidewall of each tire and follow a standard format like this: 215/55R17. Here’s how to decode it:
215 is the width of the tire in millimeters.
55 is the aspect ratio (height of the sidewall as a percentage of the width).
R indicates radial construction.
17 is the wheel diameter in inches.

Where to Find Your Exact Tire Size
Every car comes with a manufacturer-recommended tire size listed in two places:
The driver’s side door placard
Your owner’s manual
Using these sources ensures you select a size that maintains speedometer accuracy, load handling, and safety ratings.
What Happens If You Pick the Wrong Size?
Choosing a tire that’s too large or too small can result in:
Poor handling and longer braking distances
Reduced fuel efficiency
Incorrect speedometer readings
Premature suspension wear
That’s why using a reliable Tire Size Guide like this one, or referring to our Tire Size Guide, is critical for safe driving in Southern California.
Regional Factors That Influence Tire Sizing in Southern California
Due to its climate and road conditions, Southern California drivers might lean toward certain tire types and sizes. For example:
All-season tires dominate due to the warm, dry weather.
Low-profile tires are common in urban areas like Los Angeles for performance vehicles.
SUV tire sizes are popular in suburbs and desert-adjacent cities like Riverside and Palm Springs.
These regional habits affect tire size availability and can even influence tire pricing or wait times for rare sizes.
Tips for Choosing the Right Tire Size When Replacing Tires
While sticking to your original manufacturer-recommended tire size is the safest bet, there are situations where adjustments make sense:
Upgrading wheels for aesthetics or performance: You might choose a plus-size tire (larger wheel diameter, lower sidewall) to maintain overall diameter.
Switching to a different tire type: Off-road, performance, or eco tires may come in different size ranges.
Compensating for availability: Sometimes the exact OEM size is out of stock — a close alternative may work if approved by a tire specialist.
