Also, i'm not gonna crunch the numbers for you. because if i do a mistake and you end up ordering some wheels that don't fit. I don't want that on me.
Tho its also really helpful if you got a wheel to mock up, and take measurements from there, i would be more comfortable helping you, instead of you taking some rough measurements to base your new wheels on. If you are gonna order new custom wheels. I guess you are trying to run the biggest width you can fit. But remember this a 10inch wide wheel is 10inch from the inside of each bead. so from the outside beads the wheel is actually 11inches wide.
