Ok the two parts are:
1. Can anyone foresee any issues fitting 275/65/17 tyres to prado rims as replacement for standard 18inch Hilux rims/tyres. Note the prado rims are 5mm less offset and tyres will be only 15mm taller based on the tyre calc.
2. Does anyone know if the 275/65/17 are harder to get than the standard 265/65/17 if something goes wrong outback.
Thanks. Simon.
