2021 Toyota RAV4 Prime 5500 miles. The rear wheels only get power from battery. On vehicles with AWD like this, do the tires on the front and rear have to be changed at the same time? I know they do on AWD with physical drive trains, but does the computer adjust and allow for different wear on tread from the front two tires and the back two tires?
Check your owner's manual and follow its recommendation.
It is a full time AWD. So I would say, yes.
The rear part of the Toyota eAWD system ("E-Four") is just an electric motor with a differential for the rear axle.
It's not like a regular AWD that connects the rear mechanically, so there's nothing that would get worn by that.
As I personally see it, there's no reason why you would replace all 4 tires, just make sure tire pairs match.
(Although I think that might have a slight effect on drivability if the rear / front handles a bit better)
With that being said, I recommend checking if the manual says anything about it - Toyota engineers know best.
I quite unsure, although Toyota hasn't changed much, the eAWD on the new generation actually seems to work.
In theory, you would be replacing all four tires at the same time anyway. You have to rotate the tires every 5000 miles. In theory there should be more or less even wear, which would suggest changing all the tires at the same time.
