I rallycross (in a dedicated race car, not my fist) but best option is a 15 braid or compomotive wheel as they are strong and you buy a set of used gravel rally tires will give you the ultimate setup. If you are on a budget a solid winter tire will work, altimaxx artics are a favorite but anything with lots of room between the rubber lugs but when running a regular tire you need to air up to 40-45 psi when running on dirt or gravel because bumps and tire rollover will pull the bead off. You will go through the tires faster but is a decent place to start for a budget beginner. I have been organizing and running events here in Alberta for 3 years now so if you have any questions let me know.
