On the right is what i would consider an Astronomical Stretch, unreasonable on the left... just FYI
They are still safe, but at some higher speeds it may be suggested to go to a more fitting tire.

I have see 195's stretched onto 11.0" rims for cars that are just show cars and are not driven faster than 5 miles per hour

there isn't a table option out of the box. I can look at installing one though.
 
I wouldn't consider 225 over sized on a 7" wheel. :D

Old pic. Stock wheels with 225/45/17 tires.

215 is proper fitment for 7" wide wheel. 225 is fine and safe, but is by no means a stretch haha!

Anyways, yeh webby, maybe a simple table functionality? Makes things easier is. Threads like these :)

Will post my bulb fitting referrence thread this week too haha. Keep forgetting. Can't do it from my celly haha
 
my Rotiforms came with 215/35's and they are 18x9.5 thinking of putting at least 215/40's on them for this summer
 
yea....just feel more comfortable with 40's some of the roads here scare me sometimes lol i'll try to take a profile pic of them tomorrow since they are at my aunts garage...need to buy a house soon lol...
 
235/40/17 Dunlap Star Spec on stock 7" wheels. 8thcivic member Testify has this setup for track/auto-x use.
