i just put on some 18x9's i bought from jc91sc. i put 245/40/18 tires on them. the back obviously has no problem with fit. but in the front i cant even squeeze my pinky finger in between the wheel and the ...spindel i believe it is called. is this to close? there is no rubbing that i can hear feel or see so thats good. would i be ok going bigger? 255/45/18 in the front? also in the back, will 275/45/18 work? will that size tire fit a 9 inch rim and not rub on anything?
