Title: Experience with Federal Tires on Asphalt
Post by: ozzie on May 04, 2010, 04:54:23 pm
What experience have you had with the new tires? What tire pressures are you running? What things have you noticed about them?

I haven’t run them yet but my teammate did and he has nothing but positive things to say. The wear looks really good and they do NOT chunk out like some of the BFG did. He said he ran the same air pressure to start but may try less by a pound over the BFG’s. He did pick up a .10 on the watch but the track changes .50 on any given weekend. I will ask more when I talk to him. I have mine and can’t wait to get home from this trip and get them mounted up. Oh, one more thing he said that the really need at least a couple of heat cycles for break in. Hope this all helps.

Did your teammate run the same camber?
Title: Re: Experience with Federal Tires on Asphalt
Post by: IraceLegends77 on May 05, 2010, 06:32:02 pm
yes, because we really didn' have anything to go off of. He does all my set-ups as well so I'm sure we will make some changes. With that said we don't run the same set-up be cause of the way we drive and the other million reasons. I will keep you posted on what I do to my car as soon as I get home and on the track.

Dave is hopefully going to be testing his new Federal  (cut) tires tonight.
Look forward to his report on them.

Any news from Dave on the new tires?  Picking mine new cut and uncut (for wet weather) sets up on Sunday, and racing with them for the first time at the end of the month.  Anyone else want to share facts on what differences you've found?

We tested the tires on Wednesday and ran them in.  The track is a 1/5 mile paved with concrete corners.  It was about 50 degrees with no sun.  Also legends have not been at this track for 3 years.  With that said I 1st run was LOOSE off, but the track is loose off were the concrete goes back to pavement.  I could just light the tires off and burn them down the short straights.  BUT, after  the 3rd run , about 34 to 40 laps, the tires were good and I was running very very good times, compared to the books from the last legends race there.  I hope that with a bit more time on the tires and warmer weather Sat. I can get a few more ticks off the time.  I still have to be easy on the gas off, but i am being told that is the way track is.  The was  great in and stable, but a hair tight rolling in the middle. The car does rotate if i just give a bit of power.  So, I am not going to do anything to the car at this time, we will see Sat.

After race day I will report again, but as off now I like the feel of the new tires..

Dave,

Will be interested to hear your report now that you have the tires run in.
Thanks for the update!

Post by: thunder938 on May 31, 2010, 02:37:51 pm
LOL, OK I the cara was OK early on then got looser as it cooled down.  So I took a big swing at it and put a full turn in the left rear.  The car was great during the main until about 4 to go the got TIGHT, REAL TIGHT.  I was about to still pull off the win.  Now were the tire just getting fully "in" now?  I have not put the car on the scales to see where its at.  I did talk to a guy who  prac. at another track and were running 15.9-16.0s on BFGs and "said" that he turn a 15.79 on the new tire..SO I still dont know.

I like the feel of them

A win is always good news! CONGRATULATIONS!!!
Doesn't sound like much time lost on those paved tracks.
I already said that I think they look like a good pavement tire. Worried more about the guys that may have to run them on dirt. There is not much for tread.
Still waiting for real results from the dirt folks.

I dont run dirt so, I dont know how the new tire will do.  But, If it is bad it will be bad for everyone..

I will have mine on this week. I bought two sets a couple of weeks ago ,but I also had a new set of  bfg's so I ran them first.
I cant wait to try them out.

Post by: justfreaky on May 31, 2010, 09:20:20 pm
Interested to see what you think.
I have been told that they need to be scuffed in before racing on them. 30 - 40 laps to break them in.
Let us know how it goes and what you think.

Steve
Title: Re: Experience with Federal Tires on Asphalt
Post by: IraceLegends77 on June 01, 2010, 06:31:01 am
news flash------- They are just like the BFG's. They will not stick with oil under them........... ;D

But yes Steve you are right they do have a scuff period but how many laps I think depends on the surface of the track.

I ran some heat cycles into my cut Federals last week, 3 x 20-25 lap mid paced heat cycles on a 1/4 mile paved track.  I then ran a hot run of 15-20 laps and found there was a lot of grip.

On Monday 31st we were one of two cars to run these new tires at our UK Oval Track Legends Meeting.  I started heat one in 2nd out of 22 cars and finished in 2nd.  The tires went off after about 6 laps.  I then failed post race checks with a car that somehow had moved and was now 1/2" too long.  Not had chance to check it out against the BFGs to see if the tires are the reason we gained all that length.  Heat two followed a contact formula, and there was some slippery liquid on inside exit of turn 2.  The car stepped out as soon as contact was made.  I wanted a result so kept it neat and finished in 10th.  We then dropped 2lbs out off all 4 tires for feature.

In the Feature, I lined up on pole and led the race for first 20 laps, having pulled out a full straight lead in early stages.  My fastest lap was 0.3 secs faster than any I posted on BFGs at this track.  I was caught by a flying driver who won both heats and then the feature and then held onto 2nd by the end of the 30 lap race.  I am still 0.4 secs of the pace, but I was 0.7 last time, the tires helped, but they were so hot, sticky at the end of the feature they have over worked themselves. 

Now for the worrying fact - After 1 meeting, I am almost on the wear bar on the outside rear!!! Something is wrong!

Anyone got any ideas?

Did you take any tire temps?  Unless there is an issue with the tire, or it was cut pretty low, you might just be really loose. 
Title: Re: Experience with Federal Tires on Asphalt
Post by: thunder938 on June 03, 2010, 06:38:24 pm
I know a guy that ran 1 night of prac. and used up a right rear, but they were cut VERY low..

I have run 1 prac night and a race night and they still look good,

Due to finishing feature 2nd, by time we had got our trophies and done a parade lap, the temps had cooled down before I got into pits.  They were much hotter to touch than the BFGs ever got.  The INEX guy checked the durometer on the outside rear and it was 67/68.

The tires were cut by someone in the states before they were shipped.  He cuts all the dealer's tires for him, so not sure how they compare to rest.  But we lost a load of tread in one meeting.

Got to increase spring weights, as with a 240 lb driver in a coupe, back end has too much weight on it, and with the tire with a thinner tire wall, could be more natural spring on axle anyway.

I know a guy that ran 1 night of prac. and used up a right rear, but they were cut VERY low..

Could be they have been cut too low like mine.  We should not be using a tire a meeting, surely not.  I know 600 want to sell more tires, but I can't afford to!

I know that that guy had his cut WAY low and not the same cut he sells to other drivers.

Did any other tires show that kind of wear (your's or anyone else)? 
Title: Re: Experience with Federal Tires on Asphalt
Post by: thunder938 on June 04, 2010, 06:37:53 pm
My tires have one night of prac. and one race night that included some hot laps, 4 lap dash, 8 lap heat, and 20 lap main and they still look good.  The track I was at has concrete in the corners too.
Title: Re: Experience with Federal Tires on Asphalt
Post by: cryer on June 05, 2010, 02:44:47 pm
I ran mine this weekend for the first time. I put on 15 easy laps then 15 harder laps.
all I can say is I LOVE these tires. Grip is unreal !!! I still have a little more susp. work to do.

How much air pressure are you guys running on the new tires?

tires are 1 to 2 10s slower than bf with same setup wear out alot quicker softer rubber playing with springs and air  still not at speed with bf. not happy with tires . tires roll over due to soft side walls testing going on 4 race days. goingto nitrogen see if thats helps

We had our second meeting on the new Feds on Sunday, won first 22 car race (built up a 1/2 lap lead before a caution with 3 laps to run  :'( ).  Also set my fastest time of day in this clear track run.  Car was on rails! 

Second heat of 20 cars I finished 3rd, but had to work hard on different lines.  The tires allowed me to change direction quicker and easier than the BFGs ever did.  However the tires overheated and were far too hot at end of race. 

In the feature I had a battle for about 15 laps where I had to hold the car tight (to allow an outside line for guy challenging for position).  Another driver was watching my car, and due to the movement of the car (to stop it going where it want to - the outside), he could see the tire movement and thinks that is reason for the rapid tire wear I'm suffering.  The car/me is ripping the tires and not wearing them.  Not sure how to stop this......anyone got any ideas?

OK, I finally got me a set of Federals and was wondering on avergae what are the suspensions changes (or more directly) how big of suspension changes did ay'll need to make compared to what you ran on your BF's.  I am hearing you need to add alot more cross with the new tires?  Just lookin for ideas not rying to steal anyones setup (unles they want to give it up....).

Also, When you got the suspension figured out for one track with the new Fedrals were you able to translate that to other tracks easily (using what you know of your old race setup info).  I am trying to figure if I can practice primarily at one track to get everything dialed in and then somewhat easily transfer the amount of spring and wedge changes to the car for the other tracks and get somewhat close?

Let me know what you think,

Once the tires came in they have WAY more bite / grip than the BFGs and you should needed to free the car up.  I had to drop my % of cross.  That is what most guys are doing. I run on pavement.
Title: Re: Experience with Federal Tires on Asphalt
Post by: Bigmil on June 23, 2010, 01:46:34 pm
Dropping the cross.  Ok.  Do you drop it so that it is back to 48-50%?

I run pavement aswell.


Thanks,
Gerad

I had it at 49.6 and when I get my fat butt in it it dropped to about 49 flat.  I went 1/2 a turn on the left rear to free it up.  I have not scaled it to see where it is now

Does anyone have any suggestions for tire pressures on asphalt with these tires?  The car we bought came with a bunch of setup sheets with pressures, but they are all for the previous tires.  When we got our tires cut, they recommended we start at 35 on the right, 25 on the LF and 20 on the LF.  Any other suggestions?

I run 18/ 28, but my car has been loose for 3 years, it would just lite up the tires I could never get it just the way I like it.  Then put on the new tires, that have more grip, and BAM the car is right ot I had to free it up.  Now with that being said I have heard guys running very high PSI to make up for the sidewall flex in the new tire.  This will mak the new tire ack more like the BFGs.  So, if you have good set up that you like with the BFGs then you may want to try plus 10 psi per wheel.
