I have an 07 street glide with a 140/90/16 mt what car tire will fit on this

 

I've got a 2013, so it's a whole different animal. I have read a lot of threads about people wanting CT's on pre-09 models, but really the best bet would be to read all of the threads here where the OP has a 08 or older touring bike.

There aren't that many threads on the darkside of HDforums that you couldn't read all of them that the OP has a 08 or older in 20 minutes.

You will learn alot more than you would if someone just gave you a tire that would fit.

It's nice to just post "what tire wil work for me", but really spend a little time and get a better understanding of what all is involved.

My impression is that it is dicey getting a car tire that will work on a 3" rim.

I don't mind passing on information that I feel confident in, but I'm not going to do the research for you.
