Tire testing
 

I am in points a race with a kid
in a drift car with a Ls and slicks weighing
2400 lbs. I can run any tires so since I still
can't get my rear tires for Cam class I decided
to put the new Pantera Hoosier R7's out back
To run with my Bridgestone Re 71r's out front.
They say the bridgestones are like an old R6
Guess we will see next weekend.
Should be fun or wild

Ran the bird at Marina this weekend with the Hoosier out
back and Bridgestone in the front.. I thought for sure the
front end would push but the Bridgestone really stuck.. they
say like an R6.. I had the R7 out back and it worked

I was about to get out of this 200 tire stuff but if the Rival S
does what everyone is telling me we will be good.. off to Cam
Class or maybe switch right now as I cannot take first in my
Osp points race but won both days this last weekend.. thats 5 out of 6
first place finishes using both cars in the class

Bob

If you're going to auto cross the car - why don't you use the Hoosier Auto Cross tire - the A7

A for auto cross - R for road race

Trust me - I don't know much about tires -- but was just wondering why you choose the R?

Tire testing
 

Tires are for the back of the Pantera to run on the track
at Laguna.. since my buddies at BFG did not have any Rival S
tires available I decided to see what would happen and really
test the Bridgestones to see what they can do and also get
some more time in the bird.. better than having it sit in the shop

Trust me if they did not work I would be putting them up
for sale and buying A7's all the way around and get out of
the 200 tire thing... again the bird is the cross car and the Pantera
is the Track car.. Although I can drive the Pantera a hell of a lot
better and it really is not a bad cross car but no 200 tires on it
....now I can switch the back tires back and forth
if I want with the 18" wheels

Boys at the wheel place wonder what I am doing each
time I have something changed that was just done a week
or two before:)

Bob

I have to know,
what's wrong with
that space over
there >>>>>>

:D

Donny
You mean the space in the tread pattern
If so it must be some new way to keep
the tire dot but pushing the limits
I remember when they had lines each
side of center Then they moved them both to off
Center. Not sure how it dictates to a dot compliance

Bob

I think he's referring to why your typing/posts are always so much to the left side of the page...

Tire testing
 

Ok I get it now. Was just typing away

Bob

Yeah, at first I thought
it was all Haiku, but then
it was not Haiku.

When I go to various events -- I always like to talk tires with the folks that really know and test the differences between brands. It seems to be a moving target where everyone is hot on one tire or brand - and then the other guy comes out with a new or improved version and bam! Then that's the hot ticket... Right now it's the BFG. They have done an amazing job supporting "what we do".

For anyone that has never run on a set of Hoosiers.... Well... While they're not "legal" for many of the events we follow (OUSCI) -- once a guy has used some he'll be hooked. It's why I like track days -- ya get to run what you want.

Tire Testing
 

Yes the Hoosiers are the best for tracking although not all the sizes are
available... running a Hankook SCCA spec tire on the front that is also
a dot road race tire.. it is a shorter tire which the Pantera likes out front
It works better than anything else I have had there but that might also
be because the front end rides lower and works better

Bridgestones are supposed to be the best in 200 rated tires but
they still do not make a tire larger than 275.... several of the local
guys just run the 275s all the way around since it is such a good tire

Rival S tires are supposed to be a close second... Been waiting on
pulling the trigger on them but wonder if Bridgestone will make a larger tire

Tire manufacturers are still playing with this new 200 thing so each
year there are some new players etc... time will tell

Tough thing is getting your size and then when they make it they
are on back order.. sometimes for ever

Like I said these 200 tires are a lot better than I ever thought they would
ever be... it was a good test to see how a real tire worked vs this 200 thing

Bob

Just as long as people understand that 200 number is complete BS... because it's a "relative" TW rating compared to other tires IN THAT BRAND/LINE... it's not a true comparison of one brands tire to the other brand. It's supposed to be.... but this is NOT a government tested program. The ratings are set by the manufacture and then they have 6 months of "actual road use" testing etc.


Copied from The Tire Racks website:

Unfortunately, the rating that is of the most interest to consumers is the one that appears to be the least consistent. While the Treadwear Grade was originally intended to be assigned purely scientifically, it has also become a marketing tool used by manufacturers to help position and promote their tires.


UNQUOTE:

In other words -- one guys 200 might be the other guys 140.... These tests just aren't scientific and there's lots of fudge room.

Greg,
I understand what you are saying.. these 200 tires today
are pushing the limits.. but if the rules say it needs to say
200 and they buy it then so be it

If it were not for Optima or Goodguys I would not even
be thinking of running the 200 tires

Well maybe.. there is a local guy with a 66 gto clone
and and LS that I want to go run against in the CAM class

Bob

Ergo why Michelin took the Pilot Sport Cup from 80 to 180 last year.

Totally get it buddy!

like when the KDW's on a Blue Camaro at Run TO the Coast were all balled up and needed to be cooled with water spray, and everyone else running Falkens had noting similar going on.
The durometer rating on the new BFG S is somewhere around 40 that is a o TW tire
If Goodyear stamped 200tw in the side of a NASCAR tire I guess they would also be legal????

it is just a game. Falken is coming out with a new compound on the 615 lat this year as well.

Before that internet lore takes off.....

Durometer is about as useful as a treadwear number when it comes to determining grip.

I hope Falken Brings their A game with the new 615 because then we all win.....and honestly, it is going to take a lot to run with RE71s and the RivalS. Speaking of RivalS, there is supposed to be a carcass design change to sharpen its transitional response.

Why isn't anybody talking about the Kumho V720? 355s and 295s for the new viper with 200tw stamped on the side.

Agree ---- The R7 and the A7 have almost if not the same durometer reading -- and my Yokohama A001 Softs read the same as the A7's.... We do toss them when the number goes up 4 points... but that's a different issue.

Interesting on the Falkens as I was told
by someone that knows that they were getting
out of high performance tires. Would like to
see all these manufacturers keep building better
Tires for us

So I finally got my Rival S tires for the bird
Also increased the size from 315 to 335... seems
to work out good with my Forgeline wheels.. made
them a little wider and tweaked the offset slightly

Moving to Cam T this weekend to mess with the boys
in that class... can't move up or down from my second place
points in OSP so off to the next
