What 235/55R18 tires means
The code breaks down into exact measurements. The 235 is the section width in millimeters (about 9.25 inches across the widest part of the tread). The 55 is the aspect ratio, meaning the sidewall height equals 55% of that width — roughly 129.2 mm, or about 5.09 inches tall. The 18 is the wheel diameter in inches the tire is built to mount on.
Add two sidewalls to the rim and you get an overall tire diameter of about 28.18 inches, which turns roughly 716 revolutions per mile. Those figures matter to a buyer: overall diameter affects your speedometer reading and clearance in the wheel well, while the taller-than-low-profile sidewall here helps absorb bumps for a more comfortable ride.
Vehicles & uses
This size is a common fit for crossovers, compact and midsize SUVs, and touring-oriented passenger cars — the 18-inch diameter paired with a moderate sidewall is a mainstream choice for daily driving and highway travel. Because the exact fitment depends on your specific vehicle, always confirm against your door-jamb placard or owner's manual before ordering.

How to choose
Season
Match the tire to your climate. All-season tires balance dry, wet, and light-winter capability year-round; summer tires prioritize warm-weather grip; and dedicated winter tires deliver the best traction in snow and ice. All-weather models sit between all-season and winter, carrying enhanced cold-weather performance.
Treadwear & UTQG
The UTQG rating gives comparative treadwear, traction, and temperature grades. A higher treadwear number generally suggests a longer-lasting tread compound, though real-world mileage depends on driving habits and maintenance.
Load index & speed rating
The number and letter after the size (for example, 100V or 100H) indicate the load index and speed rating. Choose values that meet or exceed your vehicle's original specification — never go below it.
Warranty
Many touring and all-season tires include a manufacturer treadwear mileage warranty. Check each model's stated coverage before you buy.
