R stands for radial construction.
What is the difference between a 60 and 65 series tire?
The 65% aspect ratio (as in 235/65/17), compared to 60%, adds almost 12 mm (1/2″) to the radius of the tire (0.65-0.60)*(235mm)=11.75mm.
Will a 65 tire fit a 60?
Yes, the only real difference is that ratio between the tread width and the height of the sidewall will change. The lower the middle number the lower the profile of the tire the larger the number the higher the tire profile.
