Are you running on older asphalt that is not sealcoated ?

I'd like to hope that's not the case, after all, the Novak 25.5 is still legal. Hopefully, the same approach will be used. The phasing out of the HPI tires will happen naturally at some point anyhow.

Sometimes Ive noticed that with the HPI tires that on worn out gray asphalt the would work without traction compound , I would like to Know if the PF worked better on the worn out or sealed asphalt ?

considering both are legal right now. I would think they would remain that way until they are all gone as well.

if anything 1 year would be plenty of notice....but I would rather let them naturally fade out

I didn't see this posted and if it is sorry. The new PF tires and rims are almost 4g lighter per assembly. That is a 16g weight reduction on the car and it is rotating mass. Another ++.

be advised that you will need to add weight to your VTA car if you are running ALL PF tires/rims

its around 24 grams difference in weight. So if you are swapping your tires/rims around...you will need to check your weight to be legal

I went from the Mcalister 69 Mustang to the Mcalister Pontiac Trans-Am body and to the new R1 batteries. Had to add 35g to the car. So now between that and the new PF wheel/tire combo, I’ve had to find where to put an additional 60g on the car. I now have 110g of added weight to the car.

Does anyone make brass hinge pin carriers for the tc7?

Edit. Found some...

Right now carbon as I’m running outdoors / low grip carpet. But even with the associated aluminum chassis, it’s only 20g heavier.

Well, I’ve now experienced it myself. The PF tires are a bit of a handfulll on asphalt. While I was able to set fast lap and TQ in the third qualifier at the inaugural I-20 super speedway electric on road showdown, I ran a worn set of HPI’s in the main and set a new fast lap by .5 seconds and got an extra lap in.

I tried several configurations of tire sauce, tire warmers, and belt dressing to get the PF tires to work. This is even after a hefty heat cycle and saucing routine at the house before I left.

In the end I used a heavy coating of traction compound, let dry, then a coating of belt dressing to work the best. The tires came in after a few warm up laps but still required an easy trigger finger to keep from drifting out.

I think these tires will do fine if we can come up with a way to soften them up. Maybe a set ran for a full indoor season will make a good set for the next outdoor season.

Thanks for the information on what you're seeing. Much of this may translate for me as my local track is low to med grip asphalt as well. What springs are you running on your car? Thanks!

In USGT I ran the PSD shock inserts with 27.5 fluid f/r and grey springs f/r


In USVTA I ran the 4hole 1.1 pistons with 27.5 front and 25 rear and white springs all around. I also ran lightest away bars and a considerable amount of droop to allow the car to roll as much as possible.

I’m getting another set of the psd inserts to run in the VTA car. I liked the way the made the USGT car feel over the VTA.

That was my point earlier were it seem we should have a asphalt compound tire for VTA.
The PF tires are made for black carpet, do you guys think racers want to do all that just to get tires to work a little .

A lot of the New and less Active out door VTA racers may not want to do all that work.
( I dont either). The GT tires work indoor and outdoor just break them in and sauce them up.
If the PF tires are that hard to break in for outdoors , Ill just switch my first class to GT ( its 2nd choice now). Ill look for a new second class maybe F1
