R18 tires measure 32. SUVs and trucks. Each number in the tire code has specific meaning – 275 (width in mm), 65 (sidewall height as % of width), R (radial construction), 18 (rim diameter in inches). This is also known as the aspect ratio. The lower the number, the more ‘low-profile’ the tyre.A 275/65r20 tire measures exactly 34. The tread width spans 10. This tire size has a circumference of 107.
What is the difference between 275 65 18 and 265 70 18?
