I’m not very good at tire sizing. I have 2 wheels already for the back of the truck. 15x8 6x5,5 OS -6, BS 250, CB 4.28 I need a front wheel 15x7 6x5.5 but I don’t know what offset and back spacing to get. I’m running drum brakes all the way around. Oh and this set up is going on my 1957 truck.
Not exactly sure what you asking. You have rear wheels but need a set of tires for those wheels? Something doesn't add up with your wheel lug count and spread. Typical Chevy wheels would be a 5-lug with a 4.75 pattern. Your numbers are 6-lug by 5. Are you running different axles under your '57? They do have mock-up wheel devices out there just for your situation, although they are expensive and typically a one time expense. I would seek out a reputable tire service center in your area and discuss your concerns and let them recommend a wheel.
Apache1, 1/2 ton trucks use 6 lug wheels not 5 lug. FYI

I have a set of wheels and need a set of wheels for the front with the right off set and the right back spacing so the I’m not loosing the ease of steering. Does this make sense?
The backspace s too deep for the front with those wheels. The wheel would rub the drag link on a left hand turn. What you want is a 3.5" backspace for a proper fitment. on a 7" wheel, that would work out to a 0 mm offset.
