I've wondered this myself, foam nitro tires would kick ass on an electric TC on asphalt!!

Especially parking lots, where the course asphalt eats away at rubber tires and inserts, yet you can watch nitro guys go for 20 minutes on a set of tires.

Plus, if you aren't carefull you can "cook" a set of rubbers in only a run or two, and that's only with a 10.5!!

Nitro tires are great on asphalt. 37s are usually a good tire to start with. Around here, where the asphalt is made with limestone, so it's not too abrasive, the tires last quite a while. Carpet foams will be eaten quickly, however.

We used to save our chunked or damaged foam tires from carpet and run them on asphalt during the outdoor season. They worked well but didn't last very long. Never tried to run nitro shoes with electric.

We run foams on asphalt in TC here (no traction additive) and we use the so called nitro foams, normally in a 35shore.
For me in Mod I can get close to 2 full meetings out of a set of foams before they get too small to really be useful.

Default nitro foams

Hi,
I use nitro foams indoors on carpet and they work great, quite hardwearing aswell. I use 35 shore on the front, and 37 on the rear.

Do you use traction compound on those nitro foams indoors? I've heard it said that using traction compound on Nnitro foams makes them sticky and gum up because of the different kind of rubber that is used. Is this your experience?

I use LRP traction compound and the tyres don't get sticky or gum up. They usually take one run to get bedded in, but they're OK after that. I use Kyosho tyres.

Yeah I love foams on asphalt. I have never raced with rubber before so I can't compare. I use paragon ground fx and so far the best compound I've used.
I'm also using Kyosho tires but haven't raced them yet but they feel great so far.

Using a tyre lathe or truer will lengthen the life alot. I currently use 1 set over 2 race days although they wear quite unevenly and I don't have a tyre truer myself...

You will not get good performance with carpet tires on asphalt.

Instead of thinking electric and nitro tires think electric/carpet and nitro/asphalt.

Run the touring cars with your nitro shoes without traction compound when running on asphalt.

Don't run your nitro tires on carpet as the foam material is designed for asphalt and will not give good results indoors.

I never personally used them but a guy i race with uses Imex foamys on his losi XXX-s running 3s and VXL. He has gone over a month on one set of tires without truing them... And these are parking lot races so...

we have a race next weekend that we are running mod sedan at crystal park (10th and 8th scale onroad track) everyones going to be running 4.5 brushless, I might take some of my old 40 shore tires and check it out. probably only be able to fit fronts, but they are rock hard so they should last a while.. and traction compound is usually not used on nitro shoes for asphalt. they come up to temp and start working in about two laps.

I think foams on asphalt are the only way to go. We run the BSR tires on our pan cars and can get almost an entire season out of them. Also I ran the CRC foams on my TC3 with a 5.5, 2s lipo setup and would get over a month out of them running every wednesday and then practicing every other saturday while the 1/8 late models were running just to prove how slow their nitro cars really were. We did use both jack the gripper and paragon compounds effectively.

Hi,

I am trying to find a set of asphalt donuts for 1/12 scale. Do you know of any that work well on outdoor asphalt?

My foams lasted 2 full battery charges on asphalt. Then it was literally down to the rim. Rubber from now on.
