When choosing a rollator to help you being more stable when you walk or a weaknesses of some kind when walking, the first thing you want to determine is where you are planning to use the rollator: Inside or outside of your home? When your goal is to stay inside of your home with your new walker, you want a smooth ride, means soft and smooth tires. Although you might have some deviation in your floor, it will be mostly flat, so you won't need rugged tires on your walker. If you do have grapping, knobby tires, it will be slightly harder to push when you are rolling around a lot, since you have a bit more resistance and weight per tire than using smooth tires. If you do find what you are looking for, please let us know and we will find it.
