Few things have revolutionized land transportation as much as tires have. Without them, we would still be clanking around on metal or wooden wheels and arriving at our destinations with a sore back. Tires have truly converted that alternate future into one where we literally ride on air. Yet this same wonderful technology that helps us so much can land us in trouble at the most inopportune times if we are not proactive in its maintenance and take preventive measures for the same. Here are some that you can follow.
First of all, if you are changing only two used tires, make sure the rear ones get the nod first, if all four are close to equally wore out, that is. This is because loss of traction in the rear can be harder to get back than in the front. As a driver, you can feel the fronts losing grip and effect corrective measures quicker than with rear grip loss, which can be harder to recover from. Of course, ideally you should be changing all four used tires if they are close to being equally wore out.
Secondly, make sure you adhere to the 2/32 tread depth rule. Tread depth is measured in 1/32 inch increments. In a brand new tire, the depth is 10/32 inches. If, after a long usage period, this depth drops any lower than 2/32 on a used tire, it is as good as bald and any continued driving on it, especially on wet surfaces, is taking a risk.
Third, and this goes without saying, but always make sure your spare tire is in perfectly good condition, especially before a long trip where you might drive through sparsely populated regions with not much in the way of auto service centers nearby. Whenever you get your pressures checked at the service station, make sure you check your spare too.
Fourth, if you opt for a different manufacturer when going for new tires, make sure you read the pressure recommendations of that manufacturer as it may be different from the one you were using before. Different manufacturers have different tire construction methods and materials, so the inflation pressures will vary accordingly.
