Yes, I would think the 6" wheels would be fine for your 225 tire. I believe most RV wheels have a 0 degree offset so if you know your new setups height and width then you can check that against your existing tires to help determine how your new setup will fit. If your new tires and wheels are say 2" taller then you need to make sure you have an extra 1" clearance around the top half of your existing tires. Width difference would obviously be divided 1/2 to the inside and 1/2 to the outside. If your current tires are 225s then width shouldn't be an issue. Some tire shops, I know mine will anyway, mount up a tire or tires and wheels for one side and put them on so you can check clearances if you think its close, don't be afraid to ask them if they will. I thought I'd read on here about some issues with that wheel brand in the past, others will chime in on that too but I think they fixed that issue.
