True, the stock wheel package looks good, but it's only natural that people will start looking at the aftermarket / Acura takeoffs to give it a new look.That depends. The 2011 Odyssey uses the same bolt pattern as the 3rd gen. It is 5-120 and offset of 45-50 will work. The tire size recommendation is different.
17" 235/65R17
18" 235/60R18
If you find an Acura wheel that fits the 3rd gen, then it should fit the 4th gen. Just remember to use a slightly different tire size than the 3rd gen. I thought the 2011 EX-L came with nice 17" wheels that are not PAX? And the 2011 Touring came with 18" wheels?
Don't know what TPMS will work.
