When choosing to install two new tires, it is recommended to position them on the rear of the vehicle rather than the front. Having worn tires on the rear diminishes traction and reduces resistance to hydroplaning, potentially leading to a loss of control on wet roads as the rear of the vehicle may become unstable. Opting for new tires on the rear ensures a deeper tread with enhanced hydroplaning resistance, contributing to better grip on wet surfaces. This setup allows the driver to compensate for the worn front tires by steering, thereby maintaining control safely.
If you decide to replace one or two of the tires, the best choice is to replace them with the exact same brand, style, and size that are already on the vehicle . This is going to give you the best ride and reach peak performance from all four tires together. If this is possible, the dimensions, internal construction, materials, and tread design will be nearly identical to the tires you are replacing. If it's not possible (for example, if the tire is no longer available), the next best option is to choose tires in the same performance category with equivalent load ratings, speed ratings, handling, and traction characteristics as the original tires.
