For quite a bit less cost, the stock 15" steel wheels are still available at Toyota dealers and are a popular choice.
Both of these accept the stock hub caps for the traditional look. If you want something less traditional, the sky's the limit.
As for tires, most guys run some form of AT or MT tire. 10.5x33x15 are possibly the most common/popular choice for the stock 15" wheels, if you have a lift installed. You'll have more size choices with 16" wheels.
Which 16-inch wheels are you running? I can't tell from the photo. On my '86 FJ60 I'm running the 70-Series 16-inch wheels with BFG LT235/85R16 ATs. They are about 32 inches tall. I like the tall skinny look, and it suits the type of driving I do. I think that tire size is about the maximum you could go on an FJ40 without a lift. The BFG 30X9.50R15 ATs look good on my pretty much stock '76 FJ40, a little taller than the original tire size.
