In general, you can go with 6.35 backspacing in the rear but you'll have to do some hammer work to the inner wheelhouse - especially if you're going with a 295 or larger tire.
In the front you're safe with a maximum of 4.75 backspacing.
Be aware that there's conflicting information on the fronts: 18s may clear the UCA and allow more backspacing than 4.75. Also, going larger than 8s in the front may cause problems if you're limited to 4.75.
