The rear 450 wheels won't fit the front if that's what you want to do.
The rear wheels are 15x5.5j ET -1 , fronts are 15x4j ET +27.

About the widest wheel you can fit up front of the 450 is a 5.5" wide but it would have to be ET +34

The front wheel arches are the smallest of all generations as well; most 23" wheels rub for 300 miles :) (ask me how I know)

450 Front Wheel Widest Tires:


15" Rim (stock rim is 4" wide)



165/60/15 22.8" Diameter (rim width 4-6" wide)
175/55/15 22.6" Diameter (rim width 4.5-6.5" wide)
185/55/15 23.0" Diameter (rim width 5-7" wide)


16" Rim



175/50/16 22.9" Diameter (rim width 4.5-6.5" wide)
195/40/16 22.1" Diameter (rim width 5.5-7" wide) *this size mounted on all 4 corners; ~0.7" smaller diameter than stock


17" Rim


195/40/17 23.1" Diameter (rim width 5.5-7" wide)


I have personally tried the first 4 options with stock height suspension.
The front wheel on the 16" rim was a 16x6.5 ET 30 (451 wheel spec) But... required a 5mm spacer and the 175/50/16 tire size is not available in USA and had to be shipped in from Germany.


For the 450, getting a proper fitting Front rim wasn't much of a problem since the 451 spec wheels are close, but then you run into getting a proper fitting Rear rim (ET -1, -13) and those are pretty much unobtanium.


On a Stock 4" rim (185/55/15):



On a 16x6.5j rim (175/50/16)



You can see there is very little space in that front wheel arch, and that is a 22.9" Diameter tire.
