Changing Tire Size

Can not address the spacing however they do make a special "Spacer" (Washer) that may fix it if your lugs are long enough and you have the fender space.

That's about all I can say.

I changed last year from Goodyear G760 275/80R 22.5 to Toyo 295/75R 22.5 Load Range H. New tires were not wide enough to cause any issues with duels. Changed my odometer v. GPS by one mph at 65 mph. Have not had any tire issues over the past year.

2putt,
I'd seriously surprised if there were any interference problems with that little of size change in tires. With such a small amount of increase in any of the dimensions, I'd bet my house you're gonna no issues at all. A while ago, as in this time last year, I was in need or new tires. I had the junk Michelin 255 80R 22.5 XRV tires and they were cracked and shot. So, I wasn't about to make the same mistake the previous owner did and, I started shopping around and looking at what else I could use.

Well, long story short, I came up with some 265 75 22.5 Yokohama RY-103 tires and, like your comparisons, the size difference in any and all dimensions, was minute. I've had them on for almost a year now and, couldn't be happier. Not one single bit of clearance interference anywhere, at any time.

Chuck,

Yes, a common interchange.

Do check that you have the clearance for the slightly wider tires on full front cut angle. I would be surprised if this was a problem, but you need to verify that you have adequate clearance with the current tires to accommodate the added width.
