Lamest Day - tire wear? (Page 1 of 2)

Team name: Ded Bull Racing #94
Type of car: 94 VW golf 2.0 completely stock
Hours on track: 23+ (waiting on final results)
# of tires used: 4
Tire brand/model/condition: Falken ZE-912 195/60R14 New (complete with stickers)

At the end of the race, the left tires were pretty used up, but the right side showed significantly less wear. If we had taken the time to rotate them during the race there probably would still be useable tread depth on all 4 tires.

Great Tread wear.  Honestly if we didn't hit midway of driving at like 4 AM we would have rotated once.... and have super even wear.  We had amazing grip most of the race... we started to get some understeer at the end but we took off the rear hatch as an experiment so we added another variable - don't know if it was the tires... they seemed to have good tread left up front...

Very minimal tread and shoulder wear.  We never rotated or unbolted the tires.  We run higher presures in the rear and the car is pretty well balanced with minimal understeer.   The tires were wearing so well that at night we let the pressures drop and still the tires wore well.  Overall there was practically no wear compared to the race 3 weeks earlier at CMP.   These tires look better after 24 hours than the other tires did after only 14 hrs at CMP and 2 tire rotations.

We will measure brake pads later.  But I expect the same kind of results.

The tires sucked.

I have nothing good to say about them. After the Friday Test-n-Tune, our right front tire had a noticeable bulge in the sidewall.  No biggie, we thought, we have spares, though of a different brand.  4 hours into the race, left front does the exact same thing in the carousel, except this time it became less of a tire and more of a collection of rubber bits attached to a rim.  Again, we have spares..... 14 hours in we got a bulge in the right rear sidewall tire.  We had the Kumho guy de-mount it - we only had 2 spares rims and needed it for a third tire.  The tire was trashed - the bead had seperated from the carcass, and the tire was de-laminating from the inside.  Kumho guy said he had never see anything like that ever.

The tires were by far the crappiest tires I had every run - sure, they felt good and appeared to be wearing good, but that doesn't mean jack when the tires fail.
We finished the race on two 10 year old 'Sport-tech' tires that came with the car, and one 'Douglas' tire from walmart.

These tires are great!  We chunked the outside edge of the LF tire at CMP due to most of the track being tight right-turns.  At NL, we had almost NO wear.  Front tires barely show 1mm of wear and minimal edge wear.

Nelson Ledges, good alignment and not overdriving made for a great combination.

Type of car:  Chevy Camaro
Hours on track:  22 hours (a few penalties and an alternator swap)
# of tires used:  6 totall
Type of tyre:  Toyo Proxes TPT

The tires were great, they really made the big Camaro hook up.  We got bumped early on and ended up slashing the PS rear tire so we swapped it out.  The DS front tire was wore down to the cords near the end of the race so we swapped it out for a new one.  The PS front tossed a wheel weight so we pulled it off to get rid of the vibration, but after a trip to the Kumho truck it was ready to go back on.   The DS rear lasted the whole race and still looks to have a few miles left on it.  I'm about 90% sure that we will be running these again next year after how well they worked this year.  If we had not cut the PS rear and tossed the weight I'm sure that we could have done the whole race with only 5 tires totall.

13 hrs on track.  Home alignment to 1/16th toe in IIRC.  Tires were awesome.  ZERO grip issues.  Started with 33 cold at all corners and I don't think we touched em the entire time.  If one of the guys can chime in to support me, I am pretty sure they still have at least 85% left.  When I finished my stint at 7:30PM, we had been running for about 6 hrs.  I was driving conservatively for the last 3/4 of my session and they still had full grip.  Did not get greasy.

I run almost the same size tire (except aspect ratio 45) on my track car (89 E30 with 3.0L M20).  I've had these tires for the entire 2009 season, doing 2 full DE days each at Gateway, Mid-Ohio, and Putnam.  I ran in the advanced group in each (only mention that so you see where I'm coming from) and the tires have still about 85% left.  Splurging on R comps next season or I'd have been all over the Tire Rack's current close-out on these (be careful, though - the tires may be very old - when I bought them in 3/09, they shipped and I looked at the mfr dates...they were all 4/08).

lol your front tires, the goodyears, had around 40-42psi thats what it took to set/seal the bead i never readjusted them being we didnt have air other then a that 5 gal tank the rear tires bob summeral installed i would assume they were around 30 no more then 35 being they were 98-99 olds. intrigue wheels

Type of Car - '86 BMW E30 (Don't Hate Teh Greatness) 325A (A = Amish- it actually an E)

Hours on Track - 29th Place- no failures other than some off track lawnmowing (one black flag 10 min. penalty) that required extra pit stops and a refueling delay.  So we were on the track the whole time for the most part?

# of Tires Used - Hardly 4

Tire type - Brand or model - new or used? Falken Ziex 912 195/60 HR 14 Treadwear 480 WELL used

Our tires were shocking.  They are leftovers from running all 24 hours at Toledo (we finished 6th).  I think two of them ran all 24 hours last year!  We  decided to change right side tires once last year and after the race found the left front to be trashed by the banking.  So that left us with five used tires from last year.

We put on the used ones this year, set the pressures at 30-something and hit the track running.  During night practice in the wet they were awfully unpredictable.  no warning of losing grip- no shuddering, no slight slip, just sliding.  However in the dry on RACE day they were decent.

We never changed tires.  We kept looking at them each time we'd pit and didn't have to change them.  We've never aligned this pile of shit.  Never adjusted pressures throughout the race.  It's shocking how decent the wear was.

So we've got 7 new tires sitting in our trailer that never got track time.  Boy did we overestimate the need for tires at this track...........  A stickier tire, a better running engine and better driver change strategy would have helped us finish better.  But hey, we finished so that's huge in and of itself.

Thanks for the tip.  We have a source for a chip (guy we bought the car from) but figured we didn't want to mess with it.  Considering that the E engine is a detuned engine, it's probably silly not to RE-tune the engine.

First we gotta get rid of that pesky injector short/hesitation.  Car's been like that ever since we got it and it makes a POS car feel like a bigger POS

Police Brutality ran Fuzion HRi 225/70R15s on the Cadillac.
All of our 180-some laps were completed on one set, which shows surprisingly little wear.
