Hi Debbie,
Just what I wanted

Excellent precision sharp detail - treads, hub. No mold ridges, flashing, or other surface defects. Wheel set is attached to a relatively large soft metal tree, which does leave a clip mark where the tire is removed from the tree (ie, no detail on that small section of tread.) Although the "front" is highly detailed, the "back" of each tire has a large axle mounting hole but no other detail of any kind. Tires are 6mm diameter overall, "rubber" 1.5mm wide, wheel hub 4mm diameter, deep inset. Tire tread is 1.5mm wide. Mounting hole on back is 3mm diameter, 1mm deep. Accepts lacquer paint with good grip. Recommend removing any wheels that were molded on the vehicle and replace them with these metal alloy wheels. Exponential improvement in vehicle's appearance!
