Good day guys,
my 1984 5.7 blazer is currently on 33/12.5/r15 tires, was considering 245/75/r17 ones,
i mainly use it for offroading mainly sand dunes.
should i or should i not switch, please explain.
thx

 

The 33x12.5's will be better in the sand due to the wider tread width and larger diameter which both lead to a larger contact patch.
