I bought my 2010 SC used about 4 years ago and I still have the same aftermarket Falken ZIEX S/TZ05 265/50R20 tires on them that the previous owner put on. The rear tires are in great shape, but both front tires are now badly worn on the outside (i.e., too much positive camber or toe in?). Several shops/mechanics recently have suggested I replace them and have an alignment done. These tires are slightly wider (10 mm) and taller (10 mm) than the OEM tires (Michelin Latitude Diamaris 255/50R20). Does this accelerate the wear? I am asking because I am wondering if I should simply replace the fronts with used, same make and model, similar tread life (8/32") tires or replace all four with OEM tires to avoid accelerated wear...?
