ANSWER: Nicholas,

If I understand you correctly. you want to put on 22.5 rims and use a 305/45r22.

I'm sorry, but 22" tires do NOT fit on 22.5" rims.  That 1/2" means more than just 1/2" in diameter (which would be the tire has to stretch to fit), but the whole bead contour in that area is different.

DO NOT - I repeat - DO NOT mount any even sized tires on 1/2 rims.  People have been killed doing so!

But I don't think you can accomplish what you are trying to do without comprising something in the safety department.

I suggest you work with a local retailer, but I'll bet he will on;y be able to do a minor change and not the drastic changes you were considering.

QUESTION: no i was looking at puttin the 22.5 with the semi tires or putting on the 22 shaved down rims with the low profile tire. basically what i am askin is would a low pro tires be good enough to pull my trailer with an now have to worry about over loadin the tire do u know how much a low profile tire can handle weight wise 305/45/22

Answer
Nicholas,

As a basic rule, these low profile tires don't have enough load carrying capacity.

Here's what you need to do.

Look for the vehicle placard.  It is usually on a doorpost or in the glove box.  It will hhave the original tire size and the proper pressure for that size.  What you want to do is match the load carrying capacity of this tire at that inflation pressure.  One clue would be the GAWR's (Gross Axle Weight Rating)  The tire must equal (or better yest exceed) the GAWR at the intended pressure.

With that information, you should be able to lok up tires and see if they have enough load carrying capacity.

One hint:  If a tire is listed as a Standard Load or an Extra Load, the load carrying capacity needs to be derated 10%.  This is because these tires were intended for passenger car use and not designed for a truck.

If the tire has a "Load Range" than it is intended for a truck and doesn't need to be derated.

I think you will not find many tires that will be able to work the way you have outlined your plan.

Again I suggest you work with a local retailer.  He would be responsible for the fitment - this one is going to take same work.  BTW, he will be expected to be paid for his efforts, which will probably be in the form of the cost of the rims and tires.
