Recesses or Spokes in Alloy Rim
Some wheels have recesses in the alloy rim, such as in the photo to the right. These need to make up no more than 90% of the alloy circumference for WHEELUV™ to be fitted.
Another feature to check for are spokes. If any spokes protrude from the alloy rim, meaning the rim surface isn’t flat, then WHEELUV™ shouldn’t be fitted.
