I need some opinions on what the correct tire sizes whould be for the wheels im about to get. They are GFG laguna's that came off a IS350. I dont know the exact wheel width however I know they are 20's and staggard. The tire sizes on them now are 245/35/20 front & 275/30/20 rear. They definitely arent stretched and fit the wheel good.. so im guessing they are probably 8.5 front and 10 rear....? Any way.. Should i keep 35 in the front or move to a 30 like the rear?? here are some pics (they arent good but maybe a conosuer of wheels can give me a ball park...) THANKS!!!!!!

go with 245/30 and 275/30 and what are the offsets of the wheels??

 

Not sure. I just know that in his IS it rubbed in the back a little.. But I don't know IS's so I can't estimate what the offsets may be.

 

Anyone else have any input? Does 30's all around sound good.
