Xuv w8 petrol spare tyre size 1 inch lesser is it freely move to 300 kms

Your spare tire, be it a full-size non-matching spare tire or a compact spare, is typically a smaller diameter than your four normal use tires. It may be a slight half-inch up to a couple of inches in diameter difference and the width is usually significantly less than your factory tires. This is to save space in your vehicle when the spare tire is stored. There are significant manufacturing differences that make it clear that your spare tire is for temporary short-term use only.
