Understand the current setup
Check the tyre construction and vehicle instructions. Run-flat designs can provide limited mobility after pressure loss, but the limits depend on the tyre, vehicle and conditions. Do not treat a commonly quoted distance as a universal allowance.
Before changing construction
Ask a qualified tyre specialist to review the manufacturer guidance and wheel compatibility. Discuss how you would handle a puncture without the existing arrangement. Do not make the decision on price or ride-comfort claims alone.
Can a damaged run-flat be repaired?
Some manufacturers allow a professional repair under specific conditions. Others or particular versions may not. Driving history, internal inspection and the applicable manufacturer rules determine the answer; this website does not promise a repair before inspection.
Technical reading from the manufacturers. Always confirm the specification for your own vehicle.
