the wheels i am looking at picking up is 18x7.5 with an offset of 42......
also what size tires will be good for 17x7 with 40 offset

i was wondering what is the most appropriate size for these wheels?

sorry for posted in the wrong section but i didnt really get much help from that section

 

i would say 235/40/18.. you can fit a 245/40/18 on there, but most people say its too wide for that rim... but you can do it..
