My 2010 SR 4x4 dual cab/chassis has the good old 205/R16C size on the tyre placard. After some digging I've found out that the official profile of 205/R16C tyres is 80-82%. So it's essentially a 205/80/R16 tyre or a touch larger. Depending on which calculator you use, you get different diameter measurements.
Etyre Store calculator: 708.7mm
Exploroz calculator: 734.4mm
Tyresizecalculator.com: 734mm
My own calculations:
205 x 0.82 = 168.1mm profile
16 x 25.4 = 406.4mm rim diameter
total = 168.1 x 2 + 406.4
= 742.6mm
Then I run into the same problem when comparing to larger sizes. But if i pick a specific brand/model like BFG AT KO2 275/70/16, which BFG publishes as having a diameter of 792mm, I'm just within the 50mm maximum based on my calculations, but not if I use the other calculatorsday .
But a BFG AT KO2 at the 265/75/R16 size (which seems to be very popular with Hilux owners) is clearly too big at 804mm diameter.
Thoughts? Am I safe going with a 275/70?
Thanks
