I think the tyre wear is no different you are probably wearing them out faster buy wheel spinning to much sort that out and the tyres will last longer.
If not use mini spikes they will last longer but are not as fast I've ran blue mini spikes on the 4wd in the past they also work well.
To be honest the current layout has more carpet on the hard excdkerstion points than both previous layouts.
