Pit Bull rock beast and Proline Hyrax have been my go to tires for crawlers and 1.9 U4RC racing. Crawler innovations makes a great dual stage foam I believe called the nova. I like to trim down the rear foams just a little to get more sidewall movement under load if you are crawling. I know they are pricey but the Vanquish Method race wheels are incredible and very well made. Pick up extra ring bolts.

I have also had really good success with the Amazon prime “injora” brand. I bought a set of replica hyrax tires on plastic bead lock wheels and they were very good
