  Q: Are Alloy Wheels Dangerous and What Measures Can Ensure Their Safety and Performance on Mazda RX-7?

  A:

  When hit relying on a curb or some other solid structure, road wheels may be hazardous as they may bend, and this is an unsafe situation. Whether the tire and the wheel are bent or not the run-out of the tire and the wheel will be indicated on the dial indicators that are mounted either on the side of the tire or at the front or rear side of the tire. The radial run-out of the tire tread should not be over 0.08 in (2.0 mm) whereas the radial limit of the lateral run-out should not be more than 0.10 in (2.5 mm) as measured by a dial indicator at the side of the tire. The balance of tires and wheels plays a very important role in the overall handling, braking and performance of a car so any time one is repairing or replacing a tire, the tire and wheel set should be balanced statically and dynamically using a wheel balancer as required by the manufacturer, and the unbalance of a unbalance at the rim should not exceed 0.70 oz (20 gr). Also, the wheels should be washed after some time especially at the inside part to avoid mud and salts of the road that may cause rust and eventually rust the wheels.

  Q: How do Alloy Wheels and a Camber and Alignment Kit affect the process and importance of proper front wheel alignment on Mazda RX-7?

  A:

  Proper alignment of the front wheel is a time-consuming and tedious procedure, which involves complex and costly devices and it is best to leave their tasks to a specialist with the actual equipment. It can be useful to know the fundamentals of front end alignment to be able to deal wisely with the shops that offer this. Toe-in The front wheels will be perpendicular to each other when the steering is straight ahead; in a car with zero toe-in, the distance between the front and rear edges of the wheels is the same. In the Mazda RX-7, the toe-in is static with 0.24 in (6 mm), the front edges are supposed to be lower than the rear edges by 0.48 in (12 mm) and this results in improper tire wear should incorrectly set. Toe-in is changed by changing the length of the suspension tie rods. The angles at which the tire and the suspension upright is inclined to the vertical are called camber and caster whose angles influence tire tread contact and steering-wheel self-centering respectively. Camber and caster adjustments include loosening the four attaching nuts that have to be located on the top of the suspension strut and moving the strut mounting block to the right or left to get the appropriate angles, in the case of the RX-7, the angles are 1 10 plus or minus 30 for camber and 400 plus or minus 45 for caster.
