Hi-risers are a type of heavily-customized automobile, typically a full-size, body-on-frame, rear-wheel drive American sedan.
They are modified by significantly increasing the vehicle's ground clearance, and adding large-diameter wheels with low-profile tires.
Suspension modifications similar to those employed on lifted pickup trucks are made to give adequate clearance for the large wheels.
Hi-risers are an integral part of the music scenes in Indianapolis, St. Louis, the East Coast, the Central U.S., and Miami.
In South Florida, drivers of cars that would otherwise be considered classic and have had their stock tires replaced with 24s, are referred to as donk riders.
