General Grabber AT2's - perfect on my Sorento
Oh, you mean for the bike don't you ? Well, the Anakee 2's get a lot of love on this forum and are reasonably knobbly, I rate Avon Distanzia's highly, again quite chunky. The Conti' TKC80's are probably too off road orientated ? How about Mitas (
www.mitas.co.uk) they do some lumpy rubber, may be just what Your need ?
