Plain English, because that is the whole point of the book.
Stop Overpaying for Tires is a digital book delivered as PDF files — the complete book and the Illustrated Edition. There is no physical product and nothing ships. Your files are delivered by Gumroad the moment your order goes through, and they are yours to keep.
Buy it once, read it on every device you own, and print a copy for your own glovebox. Please do not redistribute, resell or republish the files. Quoting a short passage with credit is fine and always welcome.
All payments are processed by Gumroad under their terms of service. Prices shown on this site are in US dollars. The launch price is a promotional price and can end at any time.
It is a consumer buying and maintenance guide — educational information only. It is not a repair manual and it is not professional advice about your specific vehicle. Tires are a safety-critical component. Where this book and your vehicle manufacturer's owner's manual disagree, follow the owner's manual; where it disagrees with a qualified technician who has physically inspected your vehicle, follow the technician. Do not attempt to mount, dismount or repair tires yourself — those operations require specialized equipment and carry a genuine risk of serious injury.
Every dollar figure in the book is a general range meant to help you judge whether a quote is reasonable in your market, not a quoted price. Prices, fees, labor rates, warranty terms, brand ownership and product lines all change. Verify current information before you buy anything.
