i heard that too, thats why i put this post up lol...when i go on discounttire.com and put my vehicle info in it says that i can put 274/40/17 on the stock rim which i just stared at and thought that cant be right.255 will fit the stock rim. I've heard that you can fit 275s w/ a slight buldge. I will personally stick w/ 245s until I get new rims but that's what I've read before.
