98 Thunderbird Sport

Coming up for new tyres, I have an Avon AV55 on the front and a Avon Storm ST on rear, they seem ok, but I'm willing to try something different, but I am in the USA so certain brands/type may not be available.

So any recommendations.

I'm a fair weather rider, the roads in Oklahoma a very bad, and when it rains the concrete is very slick, so I avoid the rain like the plague - in the UK I spent decades riding in the rain, snow and sleet, so I reckon I've paid my dues!
