Been thinking about some wheel sizes lately and was hoping to tap into the wealth of knowledge here.

Q is.
What is the largest wheel tyre combo and off set for a HT Monaro without rolling the rear guards.

I was thinking of going some thing like 225 to 245/60/15 or 16s.

Q2.
If I were to fit a shortened diff what length of the housing would be best to maximise the wheel size.

Any comments or experience is appreciated.

Cheers.
