The Gravel Grinder is our original and often-imitated fast gravel design. It combines a speedy diamond center for low rolling resistance with aggressive shoulder knobs that reliably hook-up when the terrain gets soft, muddy or a bit sketchy. 

This handmade PRO version combines a supple Super Polyester casing with our durable SmartPlus Compound. 

This Challenge TLR model is hookless rim compatible.

CONSTRUCTION: Handmade
Challenge handmade tires combine comfort, performance, and grip in a way other tires can't match. Our handmade tires are assembled step-by-step by experienced craftspeople. High quality natural glues and latex coatings are applied to ultra-supple casing materials like silk, cotton, or polyester. The result is a small-batch tire with a ride feel that is simply on a different level.

SERIES: PRO
Everyday Luxury – Our workhorse handmade tire is the PRO series, delivering performance and ride feel unmatched by traditional vulcanized tires. Perfect for the rigors of daily riding.

CASING: Super Polyester 260TPI
Super Polyesters with higher thread counts of 220-300tpi make up our most affordable handmade casings. Polyester is much softer and stronger then nylon, is impervious to water and quite durable.

COMPOUND: SMARTplus
A tougher and more cut-resistant rubber compound for the demands of gravel and rough terrain. SMARTplus wears longer to keep tread edges sharper, improving confidence over mixed surfaces.

PUNCTURE PROTECTION: PPS2
Our tires designed for use on rough roads, cobbles and gravel are built with an additional layer of PPS (PPS2) on the inside of the casing.

Top-tier engine protection that runs quiet and smooth
Size: 5 Quarts
I’ve used Castrol EDGE in a couple of our vehicles and always come back to it for consistent performance. It extends the time between oil changes and holds up well under both daily driving and highway mileage. We don't "extend the time" though. It's changed, on the dot, every time. The consistency and quality of the oil's condition at change, though, is easily able to be seen that it would go for much longer. Engine runs quieter, and I’ve noticed better fuel efficiency over time compared to conventional oil. Whether that's how attentively I drive and watch the mileage meter on the dash or the oil - is up for debate ;) It doesn’t burn off as quickly either, which is great if you’re keeping an eye on long-term engine health. The bottle design pours cleanly with a smart spout, which saves unnecessary messes in the garage. Pros: Strong wear protection and long-lasting Improves engine quietness Easy-pour design Tip: Use it with a high-quality oil filter for maximum benefit don’t skimp on either part and you'll be golden.

Excellent choice for long oil change intervals.
Size: 1 Quart, Pack of 6
I'm a former dealership mechanic and for years I used whatever we had in the bulk tank which was usually Valvoline conventional. My last job was at a German car dealership. Castrol was the oil recommended by the German manufacturers and that's when I started using Castrol. In my experience Castrol is an excellent oil. My 2014 Ford just rolled over 242,000 miles and even with factory 10,000 mile oil change intervals, from what I can see through the oil fill the top end of the engine is still clean. I've never had to remove the valve cover. It's using about a quart between oil 10,000 mile oil changes which is great because when it was new it used about a 1/2 quart between changes.
