FWIW Tirerack says the section width of the 275/35-18 PSS is 10.9" and Nitto claims the overall width of the 275/40-17 NT01 is 10.91".
Are these specs reliable at all? If so, then the 17x10" et25 would be ~16mm further out than my current wheels, assuming the tires are the same size?
Would a fair test be strapping on some 15mm spacers then and see if it rubs?
