Good post. FWIW, I have no luck with rubber in parking lots. I have a lot of HP and I tend to destroy rubber after only a few tanks. I tried the Duratrax Slicks listed in the rubber article and one of the tires ripped in half while I was running the second Tank. I think a rock got caught in between the body and the tire and it ripped it. The rock sent my car flying and it scratched up my beautiful new Viper body.
I never expected to get such crappy rubber tire life. The rubber tires on my Savage have been in use for over 5 gallons and they are still in great condition. I am also finding it very difficult to get the old tires off the rims. It took me like 45 minutes last night to get one tire off and I did try to boil it. I ended up mauling the rim a bit so I should probably just buy new rims along with new tires. Looks like I need new rubber everytime I run, this could start to get expensive.
When I was picking out a Touring car I picked the RS4-18ss over the R40 because I wanted to run the thing often in parking lots at high speeds. My new found experience with parking lots and rubber tires makes me think that maybe I should have gone with a track only/foam only R40. The parking lot running is going through way too much rubber.
I guess I will find out how long foams will last when we run on Sunday.
