I am going to do a mtb race first week of march in leadville on some groomed trails. Right now I have the OEM tires and it is a 2010 so I think they are kenda somethings at 1.9. I was thinking of getting a larger volume tire and running lower pressure in the snow. I don't want to drop $100 if they aren't going to fit. All the local bike shops don't have anything in stock and if I have them order them, I own them. So has anyone had any luck with a maxxis ardent 2.4 on their XTC. It seems quite large as the stock tire doesn't have all that much room around it but you never know with the sizes anymore. A maxxis 2.4 might be the same as kenda 2.1. Any thoughts?
