Luxoluk,
I went through this myself about 8 months ago.
You say "but my SR5 index is 112L" - but that is not strictly correct. 112L is the rating of the tyre that comes with the SR5, NOT the load rating specified by the tyre placard on your door frame.
The tyre placard says -
"Load carrying capacity per axle - 1180kg front - 1570 rear"
"The sum of the load carrying capacities of the tyres fitted to any axle or axle group of this vehicle shall not be less than the relevant load shown above" ; and
"The tyres fitted to this vehicle shall have a speed category not less than "L" (120 kph)"
That works out to 1180 / 2 = 580 kg per tyre on the front
and 1570 / 2 = 785 kg per tyre on rear.
Using the largest rating of 785 kg, that means you need a load rating of 99 or higher.
