I just put my 10 maxima on eibach lowering springs. I have 18s stock on it. How bif can I go without fender modification, or so they don't rub when turning?
I'm thinking of going to 19s with a 245 40 19 tire. Would like to know if that is ok
Thanks!

 

You wont have any problem with 19s.

 

Some of our cars come from the factory with 19" rims (Sport Models). I went with the OEM 19's on my car. Take a look at the "Rims on their 7th gen..." thread. A lot of pictures & good information in there.

 

245/40/19 is a factory tire size. Just make sure the offset is right on the new wheels.
