So is there a rule of thumb for what offset is needed compared to OEM? Or does it just have to be measured in each case?
Offset of 30 is the lowest I would want to go on an 8.5 wheel up front. Leaving very little room for any tire at et35. The 8” wide with et. 30 fits the 245 wide perfectly. Et25 would have been a little better up front for a more flush fit but, that wasn’t an option.
