New Jaco Rubber Tires
#572
Tries out the Jaco rubbers this weekend on asphalt. Must say that I was not too impressed. Either I was using too warm of a tire or they really need a long time to scuff in.
Was about 65-70 degrees out and I put on a brand new set of Jaco 28's. Ran them for about 12mins to scuff them in, was sliding like crazy. Lots of loose rear end slides and not much steering feedback. For kicks I put on my old beat up Sorex 28's. With these I was stuck like glue and improved my lap times by 1 1/2 -2 secs.
Not sure what to think, should I have ran Jaco 24's? Perhaps I needed to scrub them in on a warmer day? Damn shame because they are so affordable and the wheels look killer. Outdoor season is almost over anyhow I guess, maybe I will try them on carpet over the winter.

OK heres the thing. Son and I run T2 007's he had greens on and I had blues on. He runs novak 17.5 and I run Speed Passion 17.5, he has Speed 6 body I had Stratus body.Running on carpet, temps around 65 maybe 70F ambient, Paragon compound full coverage front and rear. Both cars were loose in the rear, mine was loose front and rear not terrible though. I swapped put greens in front and blues in rear on both cars and both handled well enough I felt no more tuning was needed ( ran out of time before mains). We ran OK. Was working on the cars and both cars fronts tires were glazed over, like was putting too much heat in them during the run. We had good steering, would like a touch more, would a stiffer front spring or less dampening help? No compound on the fronts? Was only running 1.5* camber, 1/2* out front toe,2* rear in toe. More camber, more or less toe?
Was running same basic set up we ran with CS-27's.

In Vegas, these tires could do no wrong and lasted forever. On our local track, however, which has medium traction at best (ozite), it sure seems like they fall off more quickly than you'd expect. Is anybody else noticing this?
Jack, you'd mentioned in Vegas that you guys might be doing something different with the insert in the blues. Any news or progress there? Any word on how it will affect the tires?
I really like these tires and their availability, and we've made moves toward making them our spec tire this season, but the way they seem to be falling off is a bit worrisome.

We are in the process of having new inserts made for the blue tires. This insert will fill the tire up a little more, thus reducing the air gap and widening the tire slightly. The testing we have done on asphalt indicates that this improves the wear pattern and consistency of the tire. We will be doing some carpet testing very soon. I don't think we will be implementing these changes for a while, however. Perhaps after the first of the year.

I am going to give the Jaco 28's another try this weekend outside. Weather forecast is about 60 degrees and cloudy. I tuned the car last night, added 2.5 degrees of camber all round as recommended. We will see if it hooks up better.

Just an update on my last post. Now that we've been running on the carpet a while, the groove has come up quite a bit, and the tires are back to lasting nearly forever. I put 15-20 runs on a single set yesterday while doing 10 hours of tuning at the track, and my fastest laps were in the final run of the day.
We've had a lot of people convert from foam to rubber this year, and many of them have commented that the grip is nothing like they remember rubber being. Lots of people swearing off foam and running rubber with us. :-)
