Here is a good example on how to stretch your tires on two small rooms when you have bigger tires.  I purchased this tool off of Amazon because I was sick of cutting my fingers up and it works amazing I would suggest tire stretching for everybody because it looks cool and has good function and you can run many types of foams just like un-stretched tires.
Any questions let me know.
