What Does 265 and 275 Indicate on a Tire’s Sizing?

The number before the R, 265 or 275, states the tire width in millimeters from side to side along the tire. Here’s what you need to know:

• Tires that are 265 tire wide have a width of 265 millimeters
• The tires are 275 millimeters wide.

So, the 275 is ten millimeters wider than the 265. Even though the difference looks minor, it can greatly affect your car’s handing, gas mileage and how it performs.

How to Understand a Tire That Is 275/65R18

When looking at tires, you’ll typically find the size written this way:

•  275/65R18

Let’s start by looking closely at this:

• 275 equals the width of the tire (in millimeters)
• 65 = Ratio that compares the height of the tire’s sidewall to its width
• Most modern tires and those recommended, are built using the radial construction, referred to as R.
• The wheel’s diameter is 18 inches.

That’s why a 275/65R18 tire means:

• The opening for the acoustic planars is 275 mm.
• Has a sidewall ratio of 65% of 275 mm
• Has an opening for wheels of size 18 inches

The format for 265 tires is the same. To illustrate, 265/70R17 represents that size.

• The PANO wall system has a width of 265 mm.
• There is 70% sidewall height, totalling 265 mm.
• Measures 17 inches across.

Key Differences Between 265 and 275 Tires

Comparative Analysis Between 265 and 275 Tires

How Do They Perform?

When you opt for 275 tires, their extra grip and contact with the road help you avoid skids, especially when you drive fast, whether on roads or off them.

But 265 tires remain highly responsive for every-day driving and make your ride smoother under usual circumstances. This performance gap is more easily seen in severe or advanced uses.

Fueling Your Car: Which Tire Will Save You More Money?

The larger 275 tires make bringing the car to speed a bit more taxing for the engine. Tires this size might provide less fuel efficiency than 265 tires.

Drivers who want to get the most MPG should consider 265 tires. Still, the difference isn’t very big — you should notice about 1 to 2 miles less per gallon in real-world driving.

How Riders Feel

With their slim profile, 265 tires can feel softer and be even quieter on highways. More importantly, their narrow design helps them drive through pools of water more efficiently.

Yet, for the extra contact, 275 tires may have a stiffer feeling, particularly when fitted on a car not made for such a size wheel. Even so, several people who drive trucks and SUVs like the firmer, secure way the vehicle responds.

Often, 265 tires are less expensive than 275s. On average:

Does Your Car Allow You to Use 275 Tires Instead of 265 Tires?

If your vehicle allows it, you can change to 275 tires after using 265 tires, but there are a few points to think about.

✅ Verify the dome light on the ceiling doesn’t contact the wheel well when it’s on

Narrow wheel wells or suspension parts can be hit by wider tires when there isn’t enough clearance. Check the instructions from the manufacturer or talk to an expert before carrying out any work.

✅ Make any Wheel Offset changes you see fit (if required)

In some cases, adjusting the wheel offset is needed after getting wider tires to avoid rubbing or trouble with the vehicle’s stability.

✅ checking if the speedometer is within proper calibration will greatly benefit you

Different tire sizes can make your speedometer and odometer readings off and this happens more often with larger wheels and different aspect ratios. You may have to reset your expectations now.
