What rims are you guys running on your Tamiya semi truck axles, when you do these tractor conversions? There is a wealth of 2.2 sized rims out there, that fit 12mm drive hexes, but the set I ordered and received have way to much positive offset to fit my axles and allow clearance for the tractor frame. I need a rim with more negitive offset (with the hex not set so deep into the rim) or wheel wideners. I do have a set of Clodbuster wheel wideners, that will fit the 12mm hex just fine, but I'm also looking for other rim options. Something that at least looks kind of like a tractor rim.
The ultimate would be a custom machined set of rims, out of aluminum, but I am sure that's going to be expensive, and I don't even know who to talk to for something like that.
Mean time, I'll run the wideners I have, but I am open to any suggestions.
