Amazon.com and SimpleTire.com both sell heavy-duty and commercial-grade truck tires online through their websites. While Amazon.com may be a more familiar name, the selection of tires is thinner than that of SimpleTire.com due to the fact that SimpleTire.com only sells tires.
The area of Amazon.com that contains commercial tires contains a search option to filter tire search results by vehicle year, make and model, making it easy to quickly find tires that work well with a particular vehicle. SimpleTire.com also contains a vehicle search option, with the added bonus of viewing any stores in a specified zip code that have the tires in stock. This feature is helpful if the shipping charges for a particular tire are too high and a local pickup is preferred.
