I have a 2012 X Sport Coupe, with the AWD, sport brakes and 19" rims ( Front 225/45R19 Rear 225/45R19 ) and want to use the snow tires from my old coupe. The snow tires are P225/50R18 and are mounted on the 18" OEM rims from a 2010 G37X Coupe ( Not the sport ). I tried them on the front, and they mount fine but are about a millimetre away from the callipers. The wheel's turns fine, not binding but am concerned about the spacing.

I did go out and get some 5MM hub centric spacers and put them on, but am not pleased with the ride afterwards. A little bit more vibration at highway speeds. The snow tires were balanced before installing. So am thinking of pulling the spacers out.

 

I have less than two millimeters between my vossens and the Akebonos. There will not be any issue as long as you torqued down your lugs while fitting the rims.

 

I have less than 1/4" (5mm) between the snow wheels and calipers. It's tighter than I prefer but no issues. I'd say as long as nothing is hitting you should be ok. The calipers are fixed, as are the wheels once bolted on. Neither is going to move unless damaged in someway.

 

I have about 3mm w/my Wilwood BBK, the biggest concern is when you're mounting the wheel/tire, being that close it doesn't take much angle when fitting the wheel to put a ding on them.

 

I'm not sure what kind of spacers you bought, but cheap ones can just give you more headaches.

If you are really worried, buy some hub centric spacers with extended studs and use those. you shouldn't have any vibration and this way you can be sure you have enough turns on the lug nuts so they hold.

 

Well, I think i will go and pull them off this weekend. Thanks everyone for your comments, makes me feel better about running that close to the callipers.

 

Mine are only about 2-3mm away after 5mm spacers on my XS coupe so I think you will be fine been driving this way since November.
