can someone help me out , i'm buying new rear tires , so my question, how wide i can go, its a Nissan 350z 35th anniversary wheels, here specs. (rear 18×8.5 33mm offset) , currently have 245 40 but i was thinking since i'm getting new tires i want something wider, maybe 255 40 , my car is 02 GS300 and i'm on a stock suspension

255 40 ? will they rub with 33mm offset??
