Choosing between 275 and 285 tires affects more than just the numbers on your sidewall. That 10mm width difference creates distinct changes in how your vehicle handles, sounds, and performs on the road. A 275 tire measures 275 millimeters across the tread, delivering a quieter ride and better fuel economy. The wider 285 tire spans 285 millimeters, providing stronger grip and enhanced stability when you need it most.
The decision between these two sizes comes down to what matters most for your driving. Narrower 275 tires excel at daily commuting and highway driving, offering improved fuel efficiency and reduced road noise. When you want better traction for off-road adventures or need enhanced stability at higher speeds, the wider 285 tires deliver a larger contact patch that boosts grip.
Your choice depends on whether fuel economy and comfort take priority, or if traction and performance drive your decision. This guide covers everything you need to know about both tire sizes, helping you select the right option for your vehicle and driving style.
Tire size numbers follow a straightforward system once you understand what each part represents. The difference between 275 and 285 tires becomes clear when you break down these measurements and see how they affect your vehicle's performance.
These numbers tell you the exact width of your tire tread in millimeters. A 275 tire measures 275mm across its tread surface, while a 285 tire spans 285mm. This width measurement is part of a complete tire designation like 275/65R17, where the number following the slash shows the aspect ratio (sidewall height as a percentage of width), R stands for radial construction, and the final number indicates wheel diameter in inches.
The width difference between these sizes is exactly 10mm or approximately 0.39 inches. This measurement might seem small, but it creates noticeable performance changes. The wider 285 tires put more rubber on the road, creating a larger contact patch for better grip. The narrower 275 tires concentrate more pressure per square inch on their smaller footprint.
Tire height depends more on the aspect ratio than just the width measurement. When comparing tires with identical aspect ratios, a 285 tire typically measures 0.3 to 0.5 inches taller than a comparable 275 tire. The height difference becomes more pronounced with different aspect ratios - a 275/65R17 versus a 285/70R17 shows approximately 1.63 inches or 41.5mm difference in overall height.
A 285 tire is 10mm (0.39 inches) wider than a 275 tire. This represents about a 3.6% increase in width. While less than half an inch difference might not look dramatic, this extra width changes the tire's contact patch and affects cornering performance, off-road traction, and handling characteristics.
Complete tire measurements show the real impact of this width difference. A 285/70R17 measures 11.22 inches wide compared to 10.83 inches for a 275/65R17. That 3.6% width increase translates into measurable performance differences you'll notice while driving.
Real-world driving reveals where that 10mm width difference between 275 and 285 tires makes the biggest impact on your vehicle's performance.
Daily road conditions favor the 275 tires with reliable grip on both wet and dry pavement. Their narrower profile cuts through snow more effectively, reaching the traction layer beneath. Off-road terrain tells a different story. The 285 tires deliver superior traction on sand, mud, and loose surfaces through their wider footprint. This increased contact patch provides better grip when you need it most in challenging environments.
Fuel economy becomes a key consideration when comparing these sizes. The 275 tires typically provide better fuel economy due to reduced rolling resistance. Drivers frequently report a 2-3 mpg decrease after switching to wider 285 tires. This happens because wider, heavier tires demand more energy to rotate, increasing resistance against forward motion.
High-speed stability favors the wider 285 tires, which provide enhanced cornering ability through their broader stance. They feel more planted during highway driving and offer better control when you push the limits. The 275 tires counter with more responsive steering and easier maneuverability, making them ideal for daily driving situations.
Comfort characteristics vary significantly between these sizes. The 275 tires operate more quietly on both highways and city streets. They also absorb road imperfections better, providing a smoother ride quality. Despite their performance advantages, 285 tires generate more road noise due to their wider contact patch and typically stiffer sidewall construction.
Understanding if these tires will actually fit your vehicle requires looking beyond just the size numbers. Several factors determine whether your vehicle can safely run either 275 or 285 tires.
Both tire sizes share similar wheel width needs, making the switch relatively straightforward. A 275 tire typically fits wheels between 8 to 10 inches wide, while 285 tires work best on 9 to 10-inch wheels. This overlap means if your current wheels accommodate 275 tires, they'll likely work with 285s too.
The extra width of 285 tires creates potential clearance problems. These wider tires may rub against wheel wells, especially during full steering lock or suspension compression. Before making the switch, measure your current clearance carefully. Most vehicles designed for 275 tires have only minimal extra space, and that 10mm increase per side (20mm total) can make the difference between smooth operation and constant rubbing.
Stock suspension systems rarely accommodate larger tires without modifications. Running 285 tires often requires lift kits ranging from 2 to 4 inches depending on your vehicle. Some drivers opt for wheel spacers as a less expensive alternative, though this solution brings its own handling considerations. The 275 tires typically fit stock configurations without issues.
Switching tire sizes affects your speedometer accuracy and odometer readings. Moving from 275 to 285 tires changes the tire's rolling circumference, causing speedometer readings to display slightly lower than actual speed. A 285/70R17 with its larger diameter will show approximately 2-3% error compared to factory 275 specifications. Recalibration restores accurate readings.
Beyond performance and fitment considerations, the financial impact of choosing between 275 and 285 tires plays a crucial role in your decision.
Tire prices follow a consistent pattern across tire sizes. The 275/65R18 tires average $202.67, while comparable 285/65R18 tires cost $216.08. Premium models show larger price differences—BFG KO2 in 285/60/20 costs $385 compared to $235 for the 275/60/20 size, creating a $600 savings for a complete set.
Warranty coverage varies between sizes and models. The General Grabber HTS60 in 275 provides up to 65,000-mile tread warranty, while the Crossmax AT-1 in 285 offers 50,000-mile coverage. The narrower 275 tires often deliver longer tread life due to reduced rolling resistance and more even wear patterns.
