I think thats too aggrrssive for stock fenders unless you run over 3deg camber which defeats the whole purpose of going wider in my case. My 10 45 ce's with 255 barely clear as it is.

Rubber compound choice is going to be the deciding factory between these two tire widths on which one will be most effective. so see what's on the market in these sizes and let that be the deciding factor on which tire width you go with. If you end up going with a 285, then a 10.5" wheel is totally acceptable and will give you a little more fitment leeway on running the camber you want. 11 +68-70 will be very close with a 295 and your current alignment. But doable.

The trick now is finding a wheel in this spec, or do what some of us have done and go custom multi piece or take a fav single piece wheel of your choice and send it to weld craft to have it widened.

This is a helpful reference guide for you to work with to see how rim width and offset play on inner and outer fitment when you put in a control such as your current 10 +45 /255 spec Online Wheel and Tyre Fitment Calculator. Offset, Tyre Stretch and Speedo Error Will They Fit if you use max outer fitment of your current set up, you can start adding with and offset with tire width to maintain that outer fitment wile decreasing inner room with stuffing more wheel/rubber. Based on my own maximized set up, you have roughly 40mm more inner room to stuff if you keep outer fitment the same as current. Tire stretch plays a roll in this fitment, so you need to proportionally add same tire width to rim width, if not then you have to re set the whole wheel offset different, likely less aggressive on outside with less tire stretch. This is where my 11+68 with 295 comes in if you punch it all in to see how it relates here http://www.willtheyfit.com/index.php?width=255&aspect=40&diameter=17&wheelwid th=10&offset=45&width2=295&aspect2=30&wheel_size=1 8&wheel_width=11&offset2=68
