Sorry to veer this back on topic.
In 2004 and some of 2005 I ran the typical frontrunner style tires. front and back. Steel rims and moon discs. They were stable and worked well except for a serious lack of forward traction. The car is FWD and runs as much as 540 hp at the wheels. I pretty much had wheel spin whenever I was on boost and under 170 MPH or so. At El Mirage I could spin the tires from the start line through all 5 gears and through the lights. While this was humorous, the durability of these tires while being abused like this was always a question in my mind. Also, the light switch power output of my motor made "pedaling" it very difficult.
In late 05 I switched to street tires (Toyo proxies, P215-50-ZR17). I can still spin the tires but now only up to 125 MPH or so. At el mirage I think they are great. At the short course at bonneville I think they are great. I am still accelerating out the back. On the long course they are not so great. I think the front-runners are better.
I know the moon caps are better *always* but I think on my car they were ugly so off they came. If I get to a point where I need more speed I may put them on but I am nowhere near max boost so they will stay in the attic for now.
The pics above represent the car setup for different classes, taken during different years but were the easiest ones I could find
I am good to run them for a little while longer since I run a little motor (H) and the records I am running on are all under 200.
OK, you guys can now go back to discussing funny-car safety capsules, Soviet-era land speed cars and drawings of 1,000 MPH rocket cars.
