Improper rotation or worn shocks or struts
Quarter Sawn timber is more resistant to warping, (cupping, twisting etc.) It also resisits moisture penetration. Timber cut this way usually has better aesthetic looks, sometimes showing the rays. This timber shrinks more in the width than the length and not as much as plain cut/ through and through (slab) It is usually more expensive due to more wood being wastes and the increased amount of labour.
Cupping is caused by lack of regular tire rotation and proper air pressure. Check the owner's/service manual for frequency of tire rotation and correct air pressure for your vehicle.
Yes, it can but cupping can also have other causes. Over inflated tires can tend to bouce more, especially when combined with weak/worn shocks or struts.
