Split rim. Wheelfitment. Pic construction01. Hendrix Wire Wheel. About Wire Wheels: One of the less popular aspects of wire wheels is that they tend to go 'out-of tune' and need occasional straightening (or 'truing').
This is caused by the spokes stretching and by the spoke holes wearing, both of which result in a change in spoke tension. This causes the rim to run out-of-round. Consider that the weight of the car is suspended on the few spokes that are uppermost in each wheel and that they are constantly moving into and out of this weight-bearing position when the car is moving.
Add side loads from cornering and you can understand the stresses that cause the spokes to stretch and move around. Dayton%20Wire%20Wheel%20Specs. WHEEL FORM PIX. Wheel offset diagram. Tyre load index. Speed ratings chart.
