Those look like the wheels you'd find on a 2012 Acura TL.

 

2007-2009 MDX Sport.

Edit: They look slightly different? That's what looked like at first glace but now I am not so sure.

 

 

Those tend to look like either 09/10/11 sports/advance upgraded wheels for MDX.....18" were upgrade sizes.... but I could be wrong....

 

YEP those are 2012 TL Wheels

 

 

Those will work. Those wheels are on my wife's '12 SH-AWD - 18" standard wheels for the Tech package. During the winter I run a 17" wheel from the TL on her TL and also on my '17 MDX - same bolt pattern. The wheel you have will work well on the MDX. Size of the tire should be 245-60R18 for the MDX (factory size on the base MDX). Note that the 17-19 MDX have a 5x120 bolt pattern, which is the same as the TL Wheels you have shown. The '14-16 MDX have a 5x114.3 bolt pattern, which means those wheels won't work....
