I really don't suggest running 40 series tires on a 1/10 scale crawler like tha axial. You could either go with a super class rig like the G-Made stuff, or what I would highly reccomend, go with a 2.2 class rig, and run it on 2.2 tires. The 2.2 rigs are a lot more fun, especially for someone getting started. Also, there are A LOT more parts available for a person who doesn't want to have to do a lot of fabrication themselves, and there are many more wheel and tire choices for the 2.2 class.
Personally, I would reccomend getting the Axial ARTR. The axial is the best rig to get started with IMO because it's a capable crawler right out of the box. You can basically buy an axial, take it out of the box, and go crawl with the big boys. Now obviously it wont be as capable as guys who have spent years tweacking their rigs and customizing them to handle the way they want them too, but it will still handle itself well enough to run most comp courses out of the box, as long as you get the weight down low, like the battery. The best valuse by far is the Axial ARTR. It comes with really nice comp ready tires, memory foams, heavy duty lockers in the axles, bent links, and some other upgrades. Don't be scared by buying electronics. I will be able to tell you the best route to go no matter what you're budet is. We can get you a set of electronics from $60 and upwards. I might even have some stuff that I could sell you in a brother-n-law deal to help you get started, if not I can find it for you on the forums. Now if you really wanted to run 40s on an axial, you could, but I don't reccomend it at all. It's a big strain on the driveline, they're big, they don't handle nice and realistic like the 2.2 crawler tires, I could go on and on. I reccomend starting out with a 2.2 axial because it's not expensive at all, and once you get into crawling and start learning how to fabricate stuff and build stuff, then you can build a super class rig if you want.
