I can't seem to find the necessary info using google, so I'll see if anyone here knows. I have a 2015 Challenger R/T with the STP and stock 245/45R20 x 8(9?) ET24 tires/wheels. My question is will a 255/55R18 x 8.5 ET10 fit on front and 265/60R18 x 8.5 ET10 fit on the rear? I want to make sure the 18 x 8.5 ET10 wheel will fit over the larger brakes on the front and the ET10 offset will not cause fender clearance issues, and also if the taller 265/60R18 tires on the rear will clear the fenders as well. From the info I have found, the stock tires are 28 11/16" Overall Diameter X 9 21/32" Wide; the 255 fronts measure 29 1/16" OD X 10 1/16" W and the 265 rears measure 30 17/32" OD X 10 7/16" W. I do realize the taller tires on the rear would cause a speedo difference, of which is only about 3 MPH slower and it can be corrected, but will the TPMS sensors or ABS/TCM systems start sending error codes without also being corrected? Thanks for your input in advance.
