quick question about rims i ordered

[inseong]

hello i am a new member and i used the search but can't find any exact matches. I just ordered a set of gold g-force rotas in 18x8.5 with 48 offset and im getting ready to put those on as well as cobb springs with their 1inch drop. theres been so many mixed reviews about tire size and rubbing that i believe im more confused now than before my search =(

so my question is
A) what tire is ideal for my set up with 18x8.5 48 offset
and

B) will i rub with that offset and suggested rims when i also put on my cobb springs?

thanks for the help in advance cuz im noob at this stuff. (eyeballs)

235/40 is your best bet on tire size. You may rub the rear fender. If it does roll it.
