Threw this together earlier this year before the SJT and Rush tires were announced. These are Yokomo GT500 wheels/tires. Very fun to drive.

We have been testing the JST's since champs and the wear and balance of the car is pretty spot on compared to the spec foams.
The cars are a bit softer getting into the corners, and out. about .5 a lap off the foam cars but they are certainly not meant to be raced together.
Tires are not showing fall off and we are seeing a easy 3-4 race days on a set....

you wear to glue and the tire no longer works, just like foam

So they are...
1. Slower than foams.
2. Wear like foams so you will still need to adjust ride height
3. Last the same amount of time as foams

Hopefully they will also...
1. Cost more (I'm certain they will)
2. Require special preparation like grinding, gluing and heating
3. Turn out to be one run wonders at large events to get the most performance out of them

You guys realize that you can purchase a nice 1/12th scale AND a new tire truer for about the same money as a current top-end touring car chassis? The difference is the tire truer will have much better resale value in 5-years than the 5-year old touring car will.

My prediction:
All these people that "will race 1/12th scale when..."
"They slow it down"
"Use 2s batteries and electronics"
"Make the bodies more realistic"
"Use rubber tires"
MIGHT actually come do it, until they figure out that chassis setup and driving is far more critical to their success than in any other class they race... Then they're going to go race something that is easier.

Since I'm strictly an on road racer, this is a serious question for the people that race off road as well: Do you get people bitching about the need to slow classes down and needing more realistic looking bodies?

I'd like to see how you are getting 30-35 8 minute runs out of a single set of foam tires.. teach everyone and it solves a lot of problems

BullFrog 12-19-2019 05:48 PM

You guys must have your swammy hats on? The rubber tires are coming sometime soon. If they work fine if they don't that's the way it goes. As for foams in our GT12 class were get plenty of track time with each set. With the 21.5, tire wear is not like the other 1/12th classes.Tire truers are easy to use not that big of a deal.
If you want to look at a class that started with foams and after 4 times it's back stronger than ever and running rubber tires- F1! I can tell you finding foam F1 tires back in the day was very difficult for the Tamiya cars (1/11th ) and the HPI were easier with any 1/10th tire. thing change for the better: radios no crystals, batteries from 6 cell to lipos,, NO no more coms to true and brushes and springs.If rubber tires comes and they work that's the way the cookie crumbles.

F1 is dead again. 17.5 12th, WGTR, USGT, and VTR are popular over here.

BullFrog 12-19-2019 05:56 PM

As for those old 1/12th bodies in GT12 we ran some of those older bodies but have switched to the newer GT bodies. GT bodies were never that popular. A cheater 1/12th GT body that was run here in Fla was the MRP ASA Camaro . It was allowed by really was not a GT. Have one on the wall that won Concours at the Winter Champs. Can
am was the popular bodies back then and only one body was run in that class period. with all the GT bodies to choose from it just depends on what works for you.

Zero: Here in Florida WGT-R is dead (tonight stripping the final parts out the the chassis. F! and GT12 are booming Each race we see more drivers coming back. Even on guy that made chassis (1/12th and 1/10th). Actually wither on of these are the biggest classes at our state series races.

I quoted the person that’s been running them at their track. 3-4 club race nights is what they are getting out of them, not 6-8. I can get three club races on a set of purple stripes starting at 42mm on gray carpet.

​​​​Ahhh grey carpet.. that's much difference than 3 club races on black carpet.

On black carpet, 17.5, my purple stripes wear approximately .25mm per run to start. I start my tires at 42. The smaller they get, the quicker they wear. Plus add skimming the tires to get them even. I’m lucky to get 2 race nights and practice out of a set. To get 4 would be great, and I heard (you know rumors) they are cheaper than spec foams.

But it doesn’t really matter. They will be tried and people will either like them and we’ll switch, or we won’t.

I am afraid that the 1/12 class will be changed to rubber tires to increase the turnout. That it will die like WGT as it changes to WGT-R. We had a solid turnout before the change and it literally died one race after changing to Rubber Tires.

Your hoping list sounds like someone who doesn't want more competition. Any innovation for the hobby is good for the hobby. If these bring more people to the track, then what's so wrong with that? Off-road has 100 tires to choose from and that's not including compound. Never once have I heard someone bitching about a new 1/8 buggy tire coming out.

Looks nice. Which body is that?

Sabulatech VW. It's the old Bolink mold. A little too short for a modern chassis though. I had to chop the rear wheel wells to match the wheelbase of the chassis. They have other bodies that would be a good fit too.

I submit to you:

1. Timing advance/boosted ESCs, and the ability to bypass blinky mode.
2. Blob/wedge car bodies.
3. Extremely lightweight car bodies.
4. The ability to charge/discharge batteries at 40+ amps.
5. Custom built, $150+ motors (or custom-wound motors AT THE EVENT).
6. Hazardous chemicals in traction compounds, or other oils and greases.

I could go on, but the point is NOT ALL innovation is good.

only .2mm in wear in a raceday. I would not be doing any ride ht adjustments.. When they wear out they act the same as foam= they lose traction as you start to see glue. sorry for any miss understanding in questions and answers
