5lbs per corner in my book is a lot ! and can definatly help you a little bit.

as for the front wheel size ,, I wouldnt go with a 10.5'' because the wheel will definatly be outside of the fender and the 10'' +15 if there is one ..
you wouldnt be able to run a big tire anyway because they extend 6mm out t compare with the 9.5'' +15mm
I doubt you could run anything bigger than 275 if there is an 10'' +15offset

this is my guess , you can try it and give us more details !
