Tires are constructed with a (complex) combination of various fibers/ materials for different stresses/strengths, temperature ranges, locations within the tire, weather exposure, etc. Depending on testing, DOT certifications for the USA, etc. tire selection would want to include factors other than price. It may be unclear when a tire is designated "nylon" or "polyester", exactly what that construction entails. Some "nylon" tires may exhibit flat spots from sitting, exhibiting tire "thumping" until driven to warm up the plies, after which the "thumping" usually disappears. If a vendor can't supply information, testing results, user feedback, you may want to consider other sources.
