Similar issue with the BX2380. When I looked at the models sitting on the dealer's lot it looked like plenty of space. Added 2" wheel spacers for hopefully improved stability. Side fender space is not an issue. After taking delivery discovered on the user right side fender towards the front. The area below the FEL/3rd function control stick is a protective plate. R4s. I can get my hand knuckles into the space with minimal extra clearance. Guessing enough room for smaller link style chains. Probably not the ones with barb like projections.
People here note to mount chains with slightly under inflated tires. Snug down the chains and re-inflate for a nice firm fit. Great simple, practical advice.
Had a compact NH. BX is couple sizes down. Assuming chains would be less bulky and heavy for the tiny wheels on the BX. But leaning to iGrip S series studs. S have a shoulder to reduce the chance of pushing the studs in deeper if driving over rocky terrain during the non-snow seasons. Which are my conditions. BX R4s only have ~14mm deep ribs on the rear tires. Unsure how much tire thickness is below the ribs. Something to consider if studding.
My impression is that chains would be the way to go for best traction. Some here have noted front chains can be an issue on the BX. Hope is studding all four tires will make up for less traction than chains on rear only. Having steering and drive traction will be nice.
