ARE THESE OFFSETS correct?????
Size Offset
18X9 36
18X10 45

anyone have these offsets on their wheels... how do they look as far as the front and rear not sticking out....
i was told that 45 offset in the rear will work nice with the 18x10 but as far as the front offset at 36 for a 18x9. together will they look uniform?

i have an 05 gt
im looking to put 295 wide tires in the rear and 255 in the front

 

I have 38mm offset on my 18x9's. That is the stock spec. Dunno about the 10's but I would say that should work.

 

Sounds about right. The offset is pushing your wheel towards the car. When you go wider you have to allow for the extra width and making sure that the wheel is in the center of the wheelwell.
