So if u follow rim / tire norms, the max tire u can mount on that width is 295…depending on the tire manufacturer, they sometimes approve one step higher than official norms, so with approval it would then be 305. But for that the tire manufacturer usually want to know the wheel details and car details and then they check if they can approve that for safety reasons.

This sounds a bit conservative. For example, I'm looking at Nitro NT-01s in 315/30ZR20 and they spec "Approved Rim: 10.5-(11.0)-11.5" so ideally 11", but 10.5 should still be ok. Im just window shopping so far tho without a car to know how much clearance exists with stock setup.
