Rather than focusing solely on tires this time around, JensonUSA's latest batch of sales (other than some great finds in their holiday gift guide) covers a wide range of gear, including tools, apparel, as well as a host of other upgrades for your bike regardless of what type of terrain you ride on. To be fair, much of the apparel and equipment that lands in that 80% range is things that are down to a single size, but having checked several listings it's somewhat varied. Some things are small, some are medium or large, but if they're your size they're a HUGE bargain.
If you're in the market for something more complete, their Winter Bike Sale also includes some hefty savings, including up to 48% off of road bikes and up to 55% off mountain bikes. The best part is there's still time to get your orders before Christmas, just make sure to tick off the "get it Monday Dec. 24th" option as you're shopping.
