Choose quality used rims by considering the brand of the rim as well as its overall condition, as both factors are equally important. A damaged rim from an expensive brand is not a good purchase, because the damage can lead to a decrease in safety.
The first step in purchasing used rims is to determine the exact measurements of the tires. Common measurements to consider include bolt pattern, center spacing, backspacing, centerbore, and the wheel's width and diameter. The wheel's width and diameter are especially important because they determine whether or not a specific rim is compatible with a tire. While many wheels are able to fit a wide range of rim sizes, the most important factor to consider is safety. If a rim is too large it can cause undue stress on the tire and lead to a rupture, whereas a rim that is too small can cause the tire to come loose completely.
When buying used rims online, buyers need to check the entire listing description for each ad to see the full list of included components. Many listings are only for the rim itself and not the bolts or other components, which means that the final price of the rim is often higher than it first appears.
