Ok will these wheels fit a tC or are they too wide?
Size: 18x8
Bolt Pattern: 5x100
Offset (mm): +40

 

they will fit just fine, ive got 18x8.5 and 35 offset sits flush with the fender ive got the TRD drop too, only rubs in the rear when 3 passengers are in my car when going over big dips at high speed. you should be coo

 

You should be just fine as long as you are running one of the following three tire sizes:

225/40R18 ***** 235/35R18 ***** 245/35R18

 

I just tried a Fondmetal 17x7 +30 on the wifes tC. They fit well but the car made the wheels look like 15's...lol
