RC4WD Z-T0130 Krypton 1.9 Scale Off-Road Tires for RC Crawler Trucks - Perfect for Rock Crawling, Trail Adventures & Scale Model Competitions

I only have a few hours of run time on em but holy crap are they grippy. Awesome traction wet or dry on the rocks and in dirt, sand, mud and water. They're a small 1.9 but the grip they provide makes up for the lack of clearance. My only complaint is that the stock foams give almost no sidewall support, but new foams are an easy enough fix that it doesn't matter much to me. I was happy with them on the dry rocks behind my house but after a rough stream crawl, I am very impressed with these tires. I was not expecting the level of performance capability offered by these tires.
