It sounds as if your bike has 26 inch wheels. Nokian Extremes 294's might fit they come in 26x2.1.. but in reality measure closer to 1.9. Not worth it, unless you are hardcore winter rider and , you get lots of snow/ice. Nokian also has Mount and Ground in a 26x1.9 and Hakka W106, which are more suitable for commuting. You may also look at Schwalbe Marathon Winter which comes in 26x1.75. They're all good tires for winter riding, proven by lot's of winter riders who use them. Please stay away from cheap POS tires such as Innovas and Kendas.
