38" rear spare tire

[2010_5thgen]

after research, ive decided to go with the spare and not do a spare delete....way too much stuff id have to buy and change. and id rather have a spare and not need it , than not have the spare and need it. so my options are go witha 18" spare and a 38" toyo or 20" with the 38" toyo? either size will get powdercoated to match. only difference is the size and price. the 18" wheel is like 140 and probably 50-60 for powdercoating and then 400 for the tire. OR 210 for the 20" wheel and 60+ for powdercoating and around 450 for the tire?

so around 600 for the 18 or 700 or so for the matching 20" spare.....
