Its actually very easy to find a 5x114.3 in a 16" wheel. I just purchased a suzuki sx4 crossover and it comes stock with 16 5x114.3 wheels. While I was searching for wheels for it I came across hundreds of 16" wheels in 5x114.3. If I remember correctly alot of the acura vehicles, the integra the RSX and so on also come with 5x114.3. Just do a search on ebay and I bet you can find them. I know for a fact the factory 16x6 5x114.3 wheels are on there. My only question would be if they would fit over the brakes.singincanary said:It is pretty rare to find a 16" wheel in the Tribeca/'05+ STi fitiment. Our bolt pattern is 5x114.3, the older Impreza's were 5x100. I have a full sized 17x17.5 wheel with 235/65 (or maybe 60, I forget)/17 tire on it and it definately sticks down a bit, reducing clearance to about 5 inches.
I was VERY concenrned putting a full sized OEM Tribeca wheel/tire under there as the Tribeca rims are SUPER heavy and I wasn't sure of the strength of the cable. The STi 17" wheel is only about 16lbs as opposed to the Tribeca which is close to 25lbs.
