I have a kyosho ultima st racing sports rtr and im thinking of getting these rims http://www2.towerhobbies.com/cgi-bin...?&I=LXV754&P=6 question 1 will they fit?? question 2 What foam inserts would work question 3 can anyone recommend me some tires to put onto these rims thanks in advance!

Pro-Line Edges up front, M2 compound if you're just bashing, and some Dirt Works rears
and just use the included foam inserts.
