I need to do some calcs on the online sites as I think I may need to stick to 7 or 7.5 inch up front and 8 x16 et32 on rear therefore I need to find the same rolling measurement across both tyre sizes to avoid winding up the centre diff.

I want 225 or wider on rear.

I tried 8x16 et25 but it looks like a rollerscate imo.

If I go et32 up front I think the wheel or tyre may rub the arb on the front.
