In progress the all new V2 (SupermotoXL Version 2.0) wheels will be very much high in poly and mapped entirely new HD size texture to keep the details optimal and realistic.  originally most of my wheels UV mapped on 512x512 templates but now its all shift to 1024x1024 max details filled texture dedicated for SDK packages.   For 4x4 EVO2 usage it will be manually mapped back 512x512 due to its game attributes.  Currently there are about 4 sets of new wheel going to roll out this month with all new HD texture for smooth looks. These wheels are intended for RS1.
