Is a 245 tire considered very wide?

[SanBriella]

245 is considered a wide tire. Generally speaking, for car tire widths, microcar tires range between 125-155mm, while small car tires are between 165-195mm. Compact vehicle tires are around 195-225mm, and tires with a section width above 225mm are referred to as wide tires. Therefore, a tire with a width of 245mm falls into the wide tire category. Below is relevant information about tires: The marking 245/45R18 commonly found on tires represents the tire size, where 245 indicates the tire's section width (i.e., a tire width of 245mm), 45 represents the aspect ratio (the percentage of sidewall height to tire width), R denotes that it's a radial tire, and 18 signifies the tire's diameter in inches. Each vehicle model has standard tire specifications. If you switch to significantly smaller or larger tires, you may also need to change the rims. However, it's recommended to select appropriate tires based on the vehicle's standard tire specifications, as changing to different rim sizes can affect driving performance to some extent. Installing excessively large rims may cause rubbing against the wheel arches, increase the vehicle's unsprung mass, disrupt the factory-set suspension geometry, and compromise driving safety.

I've been driving for over a decade, and 245-width tires are quite common for city driving, not considered overly wide. For regular sedans or SUVs like the Camry or Highlander, this size is standard factory equipment. Compared to narrower 185 or 195 tires, they provide better stability, especially at high speeds where the car feels less floaty, with stronger grip and shorter braking distances in rainy conditions. However, when compared to ultra-wide 255 or 275 tires used on sports cars, 245 tires are relatively fuel-efficient, consuming only about 0.5 liters more per 100 kilometers. Daily usage costs are low, with minimal tire noise and simple maintenance. Even self-replacement isn't expensive. Overall, this width suits most people—it's not exaggerated and is a practical choice. Once you're used to it, you won't complain about it being too wide.

In the car modification scene, a 245 width isn't considered particularly wide. I've modified several cars myself, and 245 is most common on 17 or 18-inch wheels. It improves handling, makes cornering more stable, and provides better grip during acceleration, especially when paired with performance tires. However, it's not a track-level width—265 and above are what we call truly wide tires, which require suspension modifications to prevent rubbing on the chassis. After modification, fuel consumption increases slightly, but the trade-off for driving enjoyment is worth it. For stock cars without modifications, 245 is a good choice—it's not extremely wide, just a moderate level, suitable for those who want a bit more fun without sacrificing daily practicality. Opting for higher tire pressure can also help extend tire life.

Having repaired cars for many years, I've seen all kinds of tires. The 245 width is quite common and not considered very wide. It's a standard size for most sedans, making it easy to find replacement parts during tire changes, with convenient installation and moderate maintenance costs. Compared to narrower 195 tires, it's more durable with a larger contact area that reduces the risk of skidding, but it's not as wide as the 255 tires used on pickup trucks that might scrape the chassis. Just perform regular tire pressure checks and replace them every two years, as they don't wear out quickly. Even novice mechanics can handle them easily, so don't worry about the width causing trouble.

In terms of safe driving, 245-width tires are not considered very wide, falling into a moderate level. They provide better braking and wet road grip, with a larger contact patch compared to narrower 180-width tires, offering more stability during emergency braking and enhanced safety at high speeds. However, unlike 255+ wide tires which can be overly stiff and prone to wheel damage, 245-width tires strike a good balance. They are commonly found on family cars, cost-effective with no increase in insurance premiums, making them an excellent choice for balancing safety and fuel efficiency. Developing a habit of regular inspections can help prevent tire blowouts.
