strawberry varieties

Today I got hold of some old car tyres which I'm going to use as strawberry planters. Having never grown them before I wondered if anyone could give me some advice on suitable varieties for north west England. We get quite a lot of rain and some late frost. I'm not looking for the finest flavour but something that will happily produce fruit in our climate and be reasonably disease resistant.

Thanks Trillium, that's exactly what I intended to do. Dig out a hole under where the tyres will go, add a few inches of gravel then home-made compost and fill up the tyre with a loam based mixture. I'll just buy several varieties to give me an extended fruiting season and hope they like living up here.
