As the title guys, I'm getting conflicting info on the actual innertube size for the rear? I've just picked up a 3.50-4.00 but now been finding people saying smaller and bigger sizes. I hope someone can shed some light on this for me please

I use 120-130 "460-510" tubes...
A 350-400 will work but
could be stretched a little
thin in a 130 tyre..
