So if you upgrade from 17" or 18" OEM wheels to 19.5 Rickson's, is there a problem to "upgrade' your speedometer and TPMS?
The speedometer, depends on the overall diameter (circumference actually) of the tire wheel assembly. If the new 19.5 setup matches (or really close) the OEM setup, then no. Word of caution, in my case, many of the higher load capacity 19.5 tires where larger in diameter than my OEM tires. So there is a chance if you need the higher capacities, you have to go larger in size and have the speedometer adjusted. It's typically not hard to adjust the speedo but depends on your vehicle and resources.
