The whole point of getting a tire with the same dimensions is so I do not have to treat it like a spare/donut. I want it to be a backup tire that can perform equally IF I get a flat on my 18 rims. The whole point in getting a 17 inch is so I can get a steel wheel and deflate the spare tire to the point where I can keep it in the spare tire well.
To ensure safety, you should not let the car speed exceed 45 MPH. Also, do not drive on them for over 70 miles! 3. Run-flat Tires. Run-flat tires are the highest-performance options on the list, allowing you to reach 55 MPH for about 55 miles. Nevertheless, like other spare tires, aggressive driving will dampen the treads and traction levels
Drive slowly. Try not to go faster than about 15-20 miles per hour on a flat. Doing so may cause irreparable damage to the metal wheel beneath the tire, and could even cause you to lose control of the vehicle. Press down on the accelerator lightly, or, if possible, idle along until you find a suitable place to pull over.
