Interesting, Let me check it out. Or I will pay visit to dealer to see what is the ratio for my car based on VIN if Owner's manual doesn't state that. Thanks,.
there's a toyota technical site, but you have to pay by the day to use. there's also a toyota owners site you can plug your vin into, not sure what info it has. all the best!
I'll go out on a limb and say it's got steering ratio typical to level II through IV. All that's happened is someone's swapped wheels. You could check lock-to-lock.
Someone probably just swapped the wheels. The steering ratio I think is around 3.25 lock-to-lock. A right turn on a 2011 model II-IV will require nearly 1/2 a turn. A right turn on the V will require just a smidge under 1/4 turn (@Mendel Leisk , can you confirm?)
^ I checked that, well tried to: The amount of turn on the steering wheel is completely dependent on the radius of the turn, pretty much meaningless. A typical, quite tight right hand corner, maybe somewhere 3/4 and 1 complete revolution of the steering wheel. A more sweeping right turn, about 1/2 revolution? Bottom line, unless you control the radius it's meaningless measure.
