I am quite impressed with the new wheeled armor vehicles. It seems like the PLA is adopting a new fighting strategy with a new set of systems that includes wheeled IFV, tank-destroyer, and an artillery. They might be made for the fast-reaction troops as well as for the possibility of urban combat in Taiwan, where tracked vehicles do not travel as efficiently on the island and in urban areas. The PLA is very thoughtful in taking into consideration the varieties of terrain in designing and equipping their armies.
On the contrary, tracked vehicles are far more mobile in close terrain, like that found in an urban environment, although they are admittedly slower.
Controlled differential steering especially is a feature that makes the difference, as wheeled armored vehicles in the class of the Stryker as far as size is concerned that lack skid steering (an exception is the AMX-10RC that used only skid steering and the BTR-90 that has both conventional and skid steering - both can turn about their own axis) often cannot go in confined places without having to execute time-consuming maneuvers. Also bear in mind that wheeled vehicles are more susceptible to damage to their running gear (wheel puncture) not only by enemy fire, but by debris lying around as well.

One problem with designing modern wheeled vehicles is excessive ground pressure due to the fitting of heavier armament and armor. To counter this a central tyre pressure regulation system is fitted. That, however, makes the use of run-flat inserts in the tyres difficult and precludes the use of armored sidewall tyres like the "Commando Specials" of the V-100/150 series. The US Army Strykers for example have CTRS but not run-flats (or not fully run-flat tyres anyway) AFAIK. Also for a given squad size wheeled IFVs will invariably be larger, more complicated and (to achieve the same level of protection) heavier than a tracked equivalent.
