Great question! Generally speaking, the cost for a new 2018 Acura MDX rim is largely dependent on the seller, material, style, finish, and rim size—overall, however, you can usually expect to pay between $200 and $400 for one rim, or $800 to $1,600 for a full set.
HubCapHaven.com, for example, sells a 20x8 inch aluminum alloy 2018 Acura MDX rim with five spokes and charcoal machined finish for approximately $290.
MidwestWheelandTire.com, on the other hand, sells an 18x8 inch aluminum rim with five spokes and a machined face, gray pockets finish for roughly $400.
