You will want to go with a light center spring andf oil such as an AE silver and maybe 25 wt. oil. Try to stay away from the synthetic tires like yellow and black. They will wear down quickly and not work very well. Tire treatment is very important. Use your normal paragon or jack and let it sit for around 20 minutes. Then get yourself some cheap runny suntan lotion and apply it over the tire treatment and let it sit for at least 15 more minutes. What this will do is keep the dirt from getting imebedded in the foam. Your tires will stay clean for the whole run and you will get much better traction all around. Make sure you wipe the tires off really good before you run. You will need to do some left and right hand circles and let the car do a few spinouts until the tires come in. Also make sure that your pod is level at all 4 corners while at ride height. You should be good.
