Which tire size is cheaper?
Tire Size (Small, Medium, Large) Smaller tires, generally those that fit wheels sized 15” to 18”, tend to be more affordable than medium (19” to 22”) and large tires (22” to 26”). Height and Diameter: Because the sidewall height is a percentage of the width (the aspect ratio), a 265 tire will be taller than a 245 of the same series. For example, a 265/45R18 is roughly 0. R18.A 235 tire is slightly wider and has a larger overall diameter than a 225 tire. This difference seems small, sure! But it can change how your car feels on the road. Wider tires improve grip.
