I have stock 245/40/18 on Apex ARC8 18 x 9.5 and they are within the recommended tire width for the rim width but at the end of the range. Check the specs for your tire at Tire Rack. Probably 245/40/18 on 18 x 10 is not recommended, but kids stretch tires way beyond what is recommended. Of course stretched tires have stiffer sidewalls and that makes snow performance worse. You want some squish. I run 255/40/18 snows on the stock 18 x 9.5 rear wheels -- this size fits OK and works OK.
