Distance varies with the tire, but generally speaking, you can drive approximately 50 kilometres (30 miles) at a speed limit of no more than 80 kilometres (50 miles) per hour. The tires can be re-used and generally have a life expectancy the same as that of your vehicle. However, if you drive in isolated areas, you might feel happier with the traditional, large spare tire on a normal wheel rim. For exact details about your particular smaller-sized spare, look in your vehicle owner's manual or contact the car manufacturer directly. What's the safest way to change a tire on a busy highway? Get your car as far off the road as you can, even if it uncomfortable or difficult to do. And make sure you allow for plenty of room to work -- particularly if the flat tire is on the driver's (highway) side of the vehicle. If you have an emergency pylon or reflector, set it up on the shoulder 100 metres (300 feet) or more behind you, and if there is anyone else with you, station them near the pylon to keep passing vehicles slowed down. If you cannot keep the vehicle relatively level, or if there are other dangerous circumstances, DO NOT EVER risk changing the tire. Get some help to either move the vehicle to a safe location, or to tow it. And if you happen to be on a road or freeway or bridge where it's impossible to get out of the way, keep driving, with your flashers on. Ruining the tire or even the wheel is better than taking a chance of being hit by a moving car while you're changing the tire. What are road hazard warranties on tires all about? And what qualifies as a hazard? In general, the warranties cover normal road hazard damage, which means fabric breaks and cuts encountered under normal driving conditions that make the tire unusable. The guarantee does not include repairable punctures, chain damage, damage resulting from fire, vandalism, projection rub, theft or accident, or tire damage caused by improper inflation, wheel mis-alignment, imbalance or similar abuse. Your tire sales outlet can provide you with specifics relating to your particular purchase.
