5 Signs indicating the replacement of Car Old Tires

Just as your feet sore after a long walk, the tires on your car get old and worn every time your drive. Because of tire failure while you are driving can cause your car to go out of control leaving you stranded in the middle of nowhere. You want to know when it's time to get new tires. We have listed 5 reasons which signal you to replace out of shape old tires.
1. Tread Depth: The tread on your tires should never fall below 1/16 of an inch (1.6 millimeters) in depth. If you regularly drive on slick, wet surfaces, you'd be even better off with twice that much. If tread depth is lesser than that, take your car to the mechanic and ask for replacing them with new set of tires. (Figure a.)

2. The Tread Wear Indicator Bar: New tires have tread wear indicator bars built into the tires themselves. These bars, invisible or barely visible when the tires are new, gradually begin to appear as the tread wears down. They appear as flat rubber bars running perpendicular to the direction of the tread itself. If more than one or two of these are visible on a tire, the tread is getting low. (Figure b.)

3. Cracks in Sidewall of Tires: Look for tracks or cuts in the sidewall - grooves that are distinct enough to be visible to the naked eye. This could be a sign that your tire is developing a leak (or worse, that it's nearly ready to blow out). So if the cracks in the sidewall are starting to look serious, get that car to a repair shop and ask for the new tires. (Figure C.)

4. Bulges and Blisters on the Tire: Sometimes the outer surface of the tire begins to weaken. The result can be a bulge or blister that extends outward from the rest of the surface. This weak spot can cause a sudden blow out. Check for those tire bulges and blisters and put the car in service station before time. (Figure. D)

5. Too much vibration: When you notice too much vibration while you are not driving on the bad roads, take it to the mechanic for check out. There can be any of a number of causes for the vibration - maybe your tires are misaligned or unbalanced. The vibration could damage the tire.
