I am running
19x8.5 fronts with 40mm offset
19x9.5 rears with 45mm offset
I need to know how much spacer I can put on with out cutting tires and who makes a good set.

 

you can use 25mm all around
and still have space
or you can go a little bit more agressive w/ 30
if you went w/ 25 it would be 19x8.5 +15 and 19x9.5 +20
hoever that is the same as a 19x9 +21 19x10 +26
those are very acceptable...
talk to autornd and ask for mike..
tell him josh sent you..

 

Wholly cripes, that is a huge offset, never seen anyone mention an offset in the 40+ range.
