A lot of Land Cruiser guys use spacers and I just bought two pairs of .25 hubcentric spacers myself from https://www.motorsport-tech.com/
Have not added them yet, but another user here has and the company has a very good reputation.
My concern is safety and wear, but with .25 the amount of threads left is well above the minimum and they are factory bolts, and a 1/4 of an inch should be so minor as to fall well within the engineer's original specs.
Also, I believe 1.25 spacers will "poke" a little if that is what you are looking for?
I have 5mm hubcentric spacers front and 10mm hubcentric/wheelcentric spacers from Motorsport-tech.com as well. Installed with no issues and as smooth as it was before. I used the offset front/rear to even the track width as well as being able to fit F150 wheels for my winter set modifying the axle shafts.
These bolt between the hub and the wheel, no extra studs like the type shown in the first picture. I've had a set of these exact 10mm spacers on my Ram for 60k miles and no ill affects towing up to capacity and with high payloads.
