Ok, I've been informed by a Toyota/Scion parts guy that 225/35/19 is a rare size.
1) Is this true?
2) Are there any other options for my needs (described above)?
3) The guy said 225/45 is much more common. Will these fit?
4) Tire Rack also said 235/35 is a stock factory size.(?) Can anyone confirm?
5) What's the best place to get a great deal on these tires?

Once again, thanks to all those with helpful responses.

 

1) No, not true. Here are 31 different tires:

2) Stick with what I recommended.

3) No, that size has an outside diameter more than 2" larger than the stock tires.

4) Yes, 235/35-19 is the stock factory size for the TRD wheels, but they are +48 offset. As roXor_boXor said, he has 235/35-19 on +40 offset wheels and he rubs sometimes.

5) The website I put up the link for above has the cheapest tires online that I know of.
