[Fot] TOYOs

[James J Dolan]

For what its worth:
The Kastner 1972 GT6 runs Toyo’s and is setup at 3 degrees negative and has been running a welded rear.
The Group 44 1972 GT6 is 2.25 negative running on Hoosiers with a posi rear
Both these cars handle well, slide well and have not “snap rolled” on me in years.

The comment earlier on Avons is interesting. I looked at the web site for them and might try a set.
I run Avons on some of my other cars and they are much more predictive.
The edge of grip is much more telegraphed and the warning comes much earlier that the tire will be letting go.
They are just expensive.

The Hoosier to me grip well - and then all of a sudden they let go. They yelp once and then are gone.
They are harder to find the edge without going over the line.

My GT6 has a welded rear end.  I get virtually all my braking done in a straight line and then am easing on the gas almost immediately in most turns.  That pushes the rear end out and steers the car.
So, definitely the tires slip, and you can see it from the gummy rubber on them after a run, front and rear.  However, on tighter turns, at a certain point if I push it too far, yep, the rear end just comes around. Usually you know when it is coming, but on certain turns or perhaps when this driver is not looking for the signs, it’s been known to happen.  Generally not once they are up to temp though.
I have heard the Hoosiers are grippier cold, and no question I need two laps at speed to get full grip.

Thanks guys, all looks positive for the Toyos. What is this rumor I had heard a couple of times that they stick good, but when they let go you're gone. Is this what you are talking about Scott? I can get a little drift out of the TDs on my GT.

Thanks for the input.

I’ve run the R888s for years; this year am running the R888Rs, which seem slightly faster and more predictable. If you find R888s at this point they have probably been on the shelf since 2016.
The tires wear incredibly well and are consistent.
I’ve always been tempted to try the Hoosiers, just for comparison, but what has deterred me are camber settings.  The R888s on my GT6 like about 2.5 degrees of negative camber or more, and I’m told the bias plies only want 1 degree or less.
Thus, comparative sessions are impractical, and switching is a real commitment.

I’ve watched similar cars running on the track with the two types of tires, and my impression of Spridgets, at least, is that on TDs there is a lot more drift in the turns than with the radials.  That said, and I am sure that there are differences between the cars and drivers, there are top three Spridgets in VRG on both types of tires.  Of course, they have a solid axle in the rear, so the Toyos may not be operating under ideal conditions on those cars.  When I talked to Toyo they recommended 2.5-3 degrees of negative camber (even though their website says 1-3).

I also hear the radials last longer, though my impression of the R888s is that after 15 heat cycles or so, they lose a little grip and lap times creep up slightly.  However, seat of the pants says that is less the case with the new R888Rs.

No question the toyos are cheaper - $144 at tire rack, versus $183 for the TDs at Woodman.

No recent experience with the RA1s.

Hey Guys (and any women out there?)

OK, thinking about Toyo Proxes for my GT6 next year. 205/60x13. I run Hoosier TD S's right now and have always. looking for opinions on these options, all three are VRG approved for my car. Also anything you can warn me about or advice  for switching from bias ply to radials?  Just trying to get educated at the moment, I see a lot of guys running these but have heard some bad experience stories about spins from the learning curve or handling differences

R888R
R888
RA1

Thanks
