A Custom Whitewall for Modern Luxury Vehicles. Built the Right Way.
The 245/40R20 is not a classic car size. It lives on modern luxury vehicles the Cadillac XTS, Audi A6, Audi A7, BMW 5 Series, Lexus GS, and high-performance coupes that demand both precision and presence. Most drivers in this segment have never considered a whitewall because the options simply were not good enough. That changes here.
The 255/40R20 Custom Whitewall Tire at Alexander’s Tire Services is handmade using genuine white rubber compound, molded directly into the sidewall not painted on, not applied as a strip, not a cosmetic coating. The result is a clean, bright white sidewall that holds its color through daily driving, car washes, and street heat, giving your modern luxury build a distinctive look that no factory tire can deliver.
Available as a single tire or a complete set of 4, shipped free and fully insured right to your door.
What Sets This Tire Apart
True Whitewall Construction Not Paint, Not Stickers, Not a Shortcut
At Alexander’s Tire Services, our custom whitewall tires are built in the USA the same way the originals were with real white rubber compound integrated into the tire during manufacturing. The white sidewall is not applied on top. It is part of the tire itself.
This matters because painted and surface-applied whitewalls the kind most sellers ship peel, crack, and yellow within months. Our true whitewall construction is built to last, and every tire we sell is backed by a 1-year warranty against yellowing or cracking. That warranty is not a marketing line. It is our commitment to every customer who trusts Alexander’s with their build.
