Gravel Grinder TLR Tire
Challenge is already quite well known among the cyclocross community offering supple casings and treads to tackle various conditions on courses across the globe, so it only makes sense for the company to focus this attention into the burgeoning gravel world as well. The Italian firm has come out swinging with some excellent options and the Gravel Grinder TLR Tire is one were very excited to try off the beaten path. Developed for harder packed dirt roads or stringing up and an all road adventure with just enough tarmac between the fun bits, the tread is very similar to its 'cross-going Chicane model, however, the widths are optimized for riding and racing outside the course tape offering better grip and traction over looser surfaces. That higher volume, along with the ability to run lower pressures thanks to its tubeless construction, contributes to a smoother ride, letting you save energy and gain confidence while providing the durability needed while exploring uncharted territory.
The Gravel Grinder TLR has a fast rolling center file tread pattern with aggressive side knobs so you're fast on the pavement and hardpack while still offering impressive traction over looser terrain and while cornering hard. We're most excited about the ability to run some sealant and enjoy the security of riding and racing over sharp flits and goatheads without losing time or DNFing because of an excessive amount of flats. The tires are offered in 33, 38, 42, and 46mm options so you can find the right speed/comfort/grip combination for your local gravel and riding style.

Great Versatile Tire
I have used these tires for gravel races as well as my weekend road training rides-- typically around 40 miles long. I think they roll really well on the pavement, especially for how durable they are. Off road, I find they have good volume for comfort and surprising grip on fast fire road descents. I am most pleased with their durability. I had a road tubeless tires on before (pavement only of course) that punctured on seemingly every long ride. I have had these on for about 1,200 miles without a single puncture. I will definitely buy again.

kind of meager
Not a great tread for loose dirt/sandy jeep roads. Not enough bite on them even though it looks like the outside knobbies may have some heft, they're actually pretty tame. Installed for a rear tire so even more meager when you need some grip when climbing. Nice looking though!

This is a great gravel tire. The 700Cx38mm is a good choice for many types of gravel, dirt and sandy tracks. It also feels fast on pavement. They were quick to setup tubeless. I recommend flattening out the tires (pushing the tire beads toward the rim walls) before attempting to fill them with air. I did use a compressor, which made the job easier. The wear has been quite good, having done two 100K and two 100-mile events on moderate-to-heavy gravel with acceptable wear. They corner well with the bigger lugs along the outside of the tire. I am 175 pounds and I run these tires on Stan’s Avion Team tubeless wheels between 32-34F and 35-37R. I run the lower pressures on courses with more/gnarlier gravel and the higher pressures on courses with more pavement/less gnarlier gravel. The Avions have an internal width of approximately 22mm. The tires went on the rim with relative ease. I did soap the beads before attempting to mount them.

Very Hard to Mount!
Had to stretch these at 75 psi @ 125 degF to have any chance to get them onto 23mm wide Roval wheels. Most difficult tires I've ever mounted by far.
