Pay for shipping and I will send you one to try.

They do make a couple different models (I heard) so there may be a different size that might work better. The smallest tire I have listed will allow the bike (in it now...) to rock a bit but I still don't use straps with it and doubt it would fall over unless I pushed quite hard. Really sold on them. Picked up all of mine used and got a smokin' deal on two of them. They show up occasionally here.
