Does anyone know who makes 21 inch all terrain tires? Is there such a thing?

The Butcher

Nope. I've looked and looked, and never came across anything that would really be considered an all terrain or mud terrain in the 21" wheel size. You'll need to go up (22") or down (20") to open up some tire options.

The choices in brands, models and classes in 21" are really meager, and prices are anywhere from 50% to 100%+ more than the same tire in 20" due to smaller production volumes. I bought new 20" wheels for my Lexus entirely due to price and selection. A new set of A/S 21" OE Dunlops would have cost nearly $2K, so I spent $2K on a set of new 20" alloys, transferred the A/S 20" Pirelli OEs from my G550 to it, bought a set of 20" Geolander A/Ts for the G, and will likely replace the Pirellis with A/T Michelins when the Pirellis on the LX are shot in 12K miles.
But what's really annoying are the tire retailer websites that force you to shop by vehicle fitment. The Geolanders are not available in the G's OE 275/50R20 size, and I had to go with 275/55R20. The extra 1" in diameter is no problem, but I had to spec on the tire vendor's website that I was ordering for a GM pickup truck that's available with 275/55R20s, so that I could enter the order. When I went to have them installed, the store clerk had to get the store manager's OK to proceed with installation. How these other guys on the forum are getting 305s installed by dealers, and driving away with rubbing issues until they install spacers is a mystery to me.

I don't see either of those tires on the manufacturers websites. Not saying they don't exist, I just wasn't able to find them. Can you point us to where you found them? Thanks.

Thanks. That's really cool that they exist. I clicked the link and saw this was maybe a German site? I wonder if maybe they don't import them to the US since it's not a common wheel size on trucks over here?

its German product searcher.
In this seacher, I saw where the tires are in stock and bought with delivery by postal service.

Where do these tires ship from? Across the pond will cost a fortune.
