You do not say what tire size you currently have. There are 24.5 lo pro tires which have the identical overall diameter of some "standard" size 22.5 tires. In these cases, there are no speedo recalibration issues and yes, the bolt pattern for either size wheel is the same. Just make sure you are using the correct mounting, stud piloted or hub piloted wheel. Years back, many fleets moved from standard 22.5 rubber to lo pro 24.5 rubber because of the savings in FET on the tires.
