Does anyone, anywhere know where to find 8n 16" front rims that take a 6.00 x 16 tire with the rims having a NEGATIVE offset so that the tire will be moved out (at least 3-4") from the axle extension? Yt and J8ns do not carry such rims.... all have positive offset that set the tire within 1/2" of the axle extension. Need rims with convex shaped wheel mounting flange or otherwise have negative offset. I've looked all over on-line to no avail. One of my 8ns have these kinds of rims but they came with the tractor. Even looked at implement rims.
