for your rims as far as i know there are only 2 sizes and designs reccomended by the OEM which are available from toyota and some other authorised dealers.
As for tyres it's alwayss advisable to get the best possible tyres for you r car as they are the only link between you and the road.
You'd be better off asking the dealers whih size tyre is recommended on the cuore and then shop around to find the best deal on the correct size and freshest tyre (manufacturing date is stamped on the side but it can be changed).
whatever you do DO NOT fit tyres which are too big for the car (though many people do) as it'll destroy your wheel bearings and cause your car to haev a very hard ride as well as make your arms hurt due to the lack of power steering. you CAN go wider but not taller, all you have to do is lower the aspect ratio (profile). easiest thing to do is to get a wider tyre and put it side by side to the OEM size and you'll be able to see if it is the same height.
