These models are fitted with metric sized steel belted radial tires and a combination of the two like radials and bias belted tires could cause severe handling problems. One should also consider using pair tires on the same axle; this is because should one tire be changed it should be the same size structure and tread design as the rest. The tire pressure also contributes greatly to handling and wear and therefore it should be checked at least once a month or prior to long journeys with adjustments being made when tires are cold. To ensure the most successful outcomes of tire life, they are supposed to be rotated on a regular basis and should be changed when the depth of the tread reaches at least 1/16 inch (1.5 mm) as wear marks will signal when the tires are too tired. Correct tire pressure and driving styles are vital because sharp cornering, accelerating or braking hard and hard, or braking hard may make tires wear more, whereas tires that are so worn out that they are punctured easily or unsafe in wet weather. The pattern of tires treads could serve as an indicator of an issue in maintenance or adjustments and in case there is a problem with a tire that presents abnormal tread wear because of improper suspension positioning, the matter should be resolved. Bent, rusted, corroded, buckled, leaking of air, with a long bolt hole, or lug nuts that cannot be tightened, damaged wheels should be changed not repaired, particularly aluminum wheels which need soft cloth and mild detergent to avoid corrosion. Handling, braking, and performance are all dependent on tire and wheel balance, which could have an adverse effect on the Tire life and performance, therefore balancing must be done by a qualified shop when installing a tire. It has a small spare tire in it to save space and carry easily, and the pressure of the option should be checked regularly every month to ensure it is always at 60 psi (415 kPa). The spare tire and the wheel installed are very small in size and they should not be used with other types and sizes. Only temporary use of the compact spare until the standard tire can be mended or changed, and it is not advisable to use the temporary tire continuously at speeds above 50 mph (80 kph) and the approximate tread life of the compact spare is 3000 miles (4800 kilometers). The spare is purpose-made and it is not to be used on other vehicles since its smaller diameter will decrease ground clearance by about one inch (25 mm).
