So I am not sure I am following everything. Am I correct that you have found some wheels that you think will fit your vehicle, but they now have 295/75R22.5 junk tires on them? If so, it is very common for people to mount 295/75/R22.5 on stuff like farm trucks because they are so plentiful. I am in the trucking business and I can't give them away. I have to pay disposal fee. They will fit , but they are certainly not recommended. 295/75R22.5 should have a rim 8.25" wide. If you have found 22.5 some wheels to fit your vehicle, A 19.5 tire will be much smaller diameter than wheat cam new on your truck. I would buy them. They are very scarce. Throw away the junk 295/75R22.5 and buy some 9 R22.35 or 10 R22.5. The 7x22.5 and 8x22.5 tires became obsolete 50 years ago. And 9x225 and 10x22.5 is what everyone used and had no problems.
