I have just clocked up 8 1/2 tho Km's thats a bit over 5 tho mile, While I agree that that narrower 225 will be better if you are going to be riding on rutted roads at lower speeds. I have no Clearance, handling or rough road problems with my 245/55/16 Toyo Proxes TR1 the first thing you will notice is a bit more counter steer is needed and yes at Walking Pace it will bump steer but believe me and anyone else that has got one when they say the forget the fact it is a car tyre just attack the corners, after the first 100 or so miles you won't even notice the extra bit of counter steer.
The safety aspect is simple take it easy play with your tyre pressues between 28 and 32 psi you will find most guys are running in that range I went for the wider tyre with the higher profile for tthree reasons 1/ I liked the fat look, 2/the extra width for more stabililty while towing my slightly overweight Camper at 450kg 3/ the extra height of the 245/55 gears the bike up therefore correcting the speedo close to correct reading and better economy while towing, the rocket could have easily coped with a taller top gear.
Here in Australia we dont have as many options for brands and sizes but if you can find a tyre that hangs on better than the Toyo you will be lucky and as hellfire said it has nicely rounded corners, in conclusion try the darkside be carefull but not scared of it till you get used to it keep your pressure lower to start untill you gain a feel for it and bring up the presure a little at a time till you find the sweet spot, very few have ever gone back after they tried it but give it time one ride is not going to be enought to make a judgement unless it is a bloody long ride, oh and by the way I corner more agressively than some of my mates and regularly scrape the **** out my pegs as I said you have to find the sweet spot tyre pressure for your style
