Spare wheel question

I have a 2016 Tacoma Trd off road DCSB. I switched to SCS F5 wheels, got 17x8.5 size. Rather than spending 195 for another Scs wheel, what steel wheels out there can I get for cheap to use as a spare? Thank you.

 

The wheel size is unimportant. Key is outside diameter of your spare should be very close to OD of your existing tires.

 

Exactly. As long as you get a matching sized tire, you could run a stock TRD Sport alloy from a 2G if you wanted, or even an FJ/4Runner wheel if you found one cheap.
