on the other side ,too wide is not safer and maybe more dangerous , it also look weird

Excellent summary and video JohnnyC!!! Especially of the bead seating explanation. I never really thought about that and how it decreases the bead’s hold on the rim’s lip. If I had any inkling of going with the 33x10.5 on a steelie, they are now gone.
The more I think about my choices, the more I think I’m going to stick with my current set up and get the matching spare. I guess the main reason I considered the wagon wheels is that it is a classic look, albeit not a true traditional stock look (I think...did 40s ever come stock with wagon wheels??). But the slight downside is that tons of rigs have them, so mine would like the rest.
Now the dilemma is whether to get one 31” BFG AT to match or sell the 4 and buy 5 new 33” MT tires (either Toyo Open Country or BFG MTs). The current 31”s are practically new. Less than 2500 miles on them.
Are those 15x10?
Go to a tire/rim calculator on the net and see what size rim it calls for. The size I found on several different sites all recommended is 7-9" but anyone can do what they like no matter what I guess.
To each their own but stock in my opinion or at least something made for a cruiser
I like the split rims with 255 85 16s
Here's a photo of those rims with 255/85s:I like that tire on a 40 but I would go with these rims: 16" Wheels / Rims for Land Cruiser FJ40 FJ45 FJ55 FJ60 70 Series
16” and they take the OEM caps.
4Cruisers those pizza cutters look great! I'm an old school steel wheel guy myself
