Would these maintain the ratio front to back and fit our Marauders?

[greggash]

the tires you are talking about are too small
Height wise
I have 285/50's and they are much taller than what you are touting..

I think there would be too much wheel well showing

although the ratio may be right for the ABS

They will maintain the ratio that is needed but your speedo will be a little off. If you have a tuner you can fix that. And it will lower your gear ratio a little too. I have been running 235/45/18 up front and 245/50/18 in the rear for years now with no issues(Kuhmos) One other thing you might want to take in to consideration is the gap between tires and fenders might look alittle to large.
