Welcome to the Forum. I can't give you any specific advice on those sizes however if you have a look at one of the tyre comparison web sites this will give you information on the widths, diameter, sidewall height and revolutions per kilometre of each tyre so that you can compare.
Things to watch out for include any differences in width that can cause clearance problems, different diameters that will affect ground clearance and gearing (including the requirement to recalibrate the speedometer) and if you have a spare wheel checking that a different tyre will still fit in the spare wheel well.
After looking into changing the tyres on my plus 4 I have decided to stick with the standard sizes for the moment because of the other changes that would need to be made but please don't let that put you off.
Good luck.
