Will these tires fit ?

[jhautz]

If you stretch them to fit the sidewall of tire will be deformed and won't work like it is intended. If you truly want to force them to fit the bigger wheel then trim the inner bead of the tire so you arent stretching it all the way. That will let the tire sidewall that is left be closer to it's natrual position.

Personally I would just get wheels that fit the tires or tires that fit the wheels you have. Obviously you can make anything fit with enough work and modification.
