Which tire is wider 245 or 255?

What does 225 mean on a tire?
The number “225” stands for the width of the tire in millimeters – so in this case the tire is 22.5 cm wide. The “45” that follows is the aspect ratio – the height of the tire sidewall as a percentage of its width.
Do wider tires give a smoother ride?
As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. However, if you go too crazy and change your wheel size too much, it can cause some problems.
