I went to a scion dealer the other day and the xb they had, had 18's on it..the tires were so thin, very low profile. Can anyone tell me the size on those. Oh yeah, and what the sizes are on the optional 17's also. Thanks!

15 inch- 185-60-15
16 inch- 205-50-16
17 inch- 205-45-17
18 inch- 215-35-18

You get the point

using 185/60-15 as a base, try out this tire calculator... pretty darn useful...
