We get at least 3 to 4 race weekends out of our yellow rears. We race indoor asphalt. Yellow didn't work outside. Pink for outside.

We had our first 12th. scale racing on our outdoor asphalt track last weekend. It was a blast of course. These cars are the most fun ever.

I wanted to talk about tire wear. Man, my Grey rears were toast only after some early practice and two rounds of qualifying. At least one factor was that we just re coated the track with asphalt sealer and it makes things a little abrasive, but will say the tires went away real fast.
What compounds do you guys use for hot weather high bite asphault?

Also, I read above about tire coning. My fronts had a definate cone to both tires by the end of the day. Actually to the point that they need to be replaced. I'm assuming a little camber adjustment may slow some of that down.

All in all, I did really well in the first qualifier when my tires were all still pretty even. By the third qualifier I had lost the handle on the car because of the tires.
I bolted a new set of rears on for the main, and my car came alive. Lesson learned about 12th scale tires last weekend.. lol

Gray rear tires are synthetic tires and are not good on outdoor asphalt. You will want to go with a 2x pink or magenta. You want tires with a high natural rubber content to get the traction and durability needed for asphalt racing.
If your tires are coning up front you will want to add or remove camber depending on the direction they are coning.

I remember alot of guys running grays inside but I dont remember many running them outside.

Grays and yellows should work well indoors due to increased traction levels. Indoor asphalt is much higher traction and the track isnt nearly as dirty. You will usually find yourself trying to free the car up on indoor asphalt just as you would on carpet. Outdoors you are up against much lower traction levels and dust.

Calling 1/12th scale fans! I just wanted to shout at any of you 1/12th scale fans that may be reading this thread and happen to live within reasonable driving distance of RC Hobbies Raceway which is located in Northeast Arkansas.

We have recently seen a huge increase of interest in 1/12th scale asphalt racing. Our next regular race will not be until June 29th (after the Nats), but I am really excited to see this take off. So, if you have a 1/12 scale in the closet collecting dust, get it out and head our way..

Our next race is this Saturday. I am going to try rear Pink this time.

I was reading above and was wondering about indoor vs. outdoor asphault. What is the difference, other than the temp of the surface (which I know can be a factor)

I was seeing posts reflecting "indoor high bite asphalt" Ours is outside and the grip is unreal. You can basically just hammer the throttle down and the car goes. I'm not sure if the grip could get any higher.

I wash down the track before each race day, and then spray it down with a mist of grape soda out of a garden sprayer. The grip is sick after that, even in the Houston heat!


Thanks for the answer on the coning of the front tires. You wouldn't think that the car leans that much but it does. After a day of racing my fronts were drastically coned, and my camber is pretty much level with new tires.

We run on some pretty high bite asphalt tracks here in florida but nothing like indoor asphalt. If you have ever been to races like snowbirds or IIC, that is the type of traction that an indoor asphalt track is capable of yielding. It is pretty crazy. The cars get very darty and need to be freed up. This is when you would go to a synthetic tire and some setup changes. Outdoors you will get dust and track temp changes that kinda keep the traction leveled off. Traction can be high outdoors but it just isnt the same as indoors.

It sounds like fun. Of course we are only running stock at this point. The difference between good grip in stock and good grip in mod is two completely different things.
