Starting prices on eBay auctions are more or less meaningless when a number of people are interested and there are 45 watching at present. These wheels and tyres reached £210 last time around, then the buyer didn't pay up so I've relisted. I don't want the hassle of posting, neither do I want to set a Buy It Now price. I can advise on a courier pick up firm which doesn't insist on onerous packaging. Their charge would probably be around £65 plus a little for insurance.
If you inflate the tyres and cut circle's from cardboard place one either side of the tyre wall and tape a cross shape around the tyres with 2 inch tape,
job done and very light weight, the air in the tyre will protect the edges,
most shops will be happy to give you some cardboard, best item would be a 42'' LCD TV box or similar.
GLS are a excellent service also, they charge by size and not by weight so you may be able to ship them for £40-£50 tracking provided as standard.
