I have a solution for you, but there are no 2" hitches available for your 2010 Infiniti EX35 and even if you used a hitch adapter like the Brophy # HTAD it would reduce the tongue weight capacity by 50% down to 75-lbs total for the carrier and bikes. If you're only carrying 1 bike and a very light weight carrier this may work for you. The best solution would be to go with a bike rack that will fit on a 1-1/4" hitch like the Curt # C11510.
If you wanted to get a new rack that would fit... view full answer...
