I NEED HELP FAST PLEEEZ (TIRE)

I want to order my new tires today. I was thinking of going from falken fk452 to Nankang . I want to put a 225/35/20 on a 20x8.5 front, and a 245 or 255  /35/20  on a 20x10 rear . Is this a safe thing to do, and will they fit . If so what should I go for,.. a 245/35/20 or a 255/35/20 in the rear. My car is slammed and I want to go lower. Here is a pic as to why I need a thinner tire.

AS YOU CAN SEE THE TIRE HITS THE FENDER ON ALL TURNS.

Damn! That's TIGHT *pun intended*

Good stuffs there mate!

I JUST TOOK A LOOK AT PANCAKES CAR , AND SEE THAT HE HAS NANKANG 225/35/20  ON A 9 AND A 245/35/20 ON A 10. THIS HELPS OUT A LOT , GOODBYE FALKEN 452 , HELLO NANKANG!

ya 225 35 19 on 8.5J is good, also 235 35 19 or 245 35 19 on 10J is also good to. If u can clear 245 on 10J then go with 245

you should be fine..i run a 215 on my 9 and a 225 for my rear on a 10 with falken452 tires.
i drive it every weeken just gotta watch out for those potholes.

Roll your fenders if they aren't already. Maybe a slight pull. Your rims don't look like they have huge offsets that they wouldn't clear...any profile shots? better shots at least?
