Nope, not without major mods. However, you could go as large at 19x8.5 rims with 235/35-19 sized tires.

No because they were built with 18 inch tires so you cant change them.

you can do anyhting with enought $$$ you will probibly need to lift the car, and need very expencive tires that will cost alot to mount and balance, you speedo will be off and you gasmilelage will be reduced. I would go with 18s and a 225/40-18 size tire that will cost you like 1000s less (no lift, no mielage loss, and no speedo off)

Yes

No
