the standard ford stud pattern is 5x 114mm pcd I think from memory. I can't remember the offset but it is on the major mag wheel manufacturers websites. The same stud pattern is used on many toyotas eg ford wheels fit hilux 2wd etc.
The practical limit would be 9 inch wide. I had 17x8 with no clearance issues lowered.
