Found some cool stuff while helping out some guys over at TFans. Their 1:24 44" Super Swamper tires with Weld rims. They are the exact same size as the ones I used on my Trailbreaker. Check it out here if you haven't seen it yet. And here's an idea of how they would look on Prime. Overall they look great! The quality is even better than most model kit tires. I got them through RPP Hobby at their eBay store. They cost about the same as a regular model kit but I haven't seen a kit with big tires like this since the one I got for TB. And that kit has been discontinued. The only thing is that if you do use these on an Alternator, you will have to mod the location of the axle mounts in order to fit.
