Try to set the tyre pressure up, it reduces temperature. Putting a softer suspension on the hot wheel also helps, try to distribut the heat thru all the tyre, don't let it heat in just one place. Pedal to the metal.

Please anyone. I can't figure out how to keep my front tires from "cooking". It seems that I have to pit more than everyone else! I have even lowered my air pressures. It's discouraging when I am in the lead for 50 laps and then have to pit cause my tires are cooked! Can anyone Please help me? Just get My e-mail from my address on top. Mike In Michigan!

Your chassis set up is way out of whack. Check out Joe Farr's Set Up guide at www.ivga.com Then adapt the set ups to your own driving style. BTW, lowering the tire pressure increases traction and RAISES the tire temps. -Koz

Check out Joe Farr's Set Up :guide at www.ivga.com :Then adapt the set ups to your own driving style. : :BTW, lowering the tire pressure increases traction and RAISES the tire :temps. : First of all, what track is it?? All of the tracks of their own characteristics. Some are just known to be just "push" tracks, i.e. Atlanta. Hmm..how do I start?? So you got the common "right front burn out", eh? 1)Before you even begin, be sure to KNOW the line at the track! I have seen many replays that people have sent me to view their lines. Majority of your problems are usually here. Just send me the replay..I will look at it if you want me to..cool?? 2)Are you driving "too" hard into the turns?? Please, please do not drive hard into the turns unless you have to.. I can understand in " Qualifying " but not during a race, unless it's the last remaining laps of the race. Remember during a race, is to run consistant laps, save your tires, and try to go the distances on fuel. I have seen too many people during races trying to win the race from the start and try to "lead" majority of the laps during the race, only to be hurt when the tires are all "wore" out!! As you enter a turn, set the car to hit the desired apex. Now the key here is to have a suspension that can "set" it's way "to" and "from" the apex of the turn. The ability of the car to stay "stable" the turns is the shocks, then the left bias. Got it?? Entry in the turn is dependent on the following things: 1) Rear Bias: Usually the more you run, the looser the car. PLUS, you can carry more speed into the corner!! Try it.. 2) Shocks: Generally the right front is usually lower than the right rear ( for ovals ). The left side shocks are always lower than the right side shocks [(makes the car turn easier) changes on "flat tracks"] A "stiff" shock causes more "heat" into the tire, rapid weight shifts on the chassis. A "soft" shock causes "slow and less heat build up". The weight moves "slowly" with this type of shock. Hint!! Hint!! This type of shock setting is for a race setup or an overly "hot" tire!! 3) Tire pressures: Depending on what you are trying to do, tire pressure are usually fine tune adjustments for the setup either race or qual. From what I have seen, majority of the tracks will usually have 49-50 right front tire psi; 51-53psi right rear; 50-51 left rear; and 47-49 left front. The key here is to have tire temps in the 200-220 range. You can change the way a car feels just by tire pressures!! Remember that. 4) Spoilers: Rear Spoiler: The less this setting is the "looser" the car, and higher temperatures to the rear tires!! And of course, higher top speeds can be obtained. Front Spoiler: This is where people neglect the most!! Common sense tells you if you lower the put the front down, the more downforce and grip there is to the front tires, to a certain extent. You see, you are applying alot of load on the front tires, after several laps, you will notice the car beginning to "tighten" very quickly. What I mean is, your tire temps will increase very shortly and the "push" is starting to become evident. If you raise the spoiler, you alleviate some of the load onto the front tires, increasing the LIFE of the front tires. Are you getting the picture yet?? Now I can hear all of you saying, " if you raise the front spoiler, the car will push faster!!" No, you won't. If you have gotten the "FEEL" with ALL of these auto racing sims, you will notice how much better control you have of the car and how long it will last on a LONG green run. Race setup here. Now raising the front helps only to a certain extent mind you!; ) Of course, you get more top speed out of it. As you raise the front, you will notice how easy it is to turn the car. Now this is of course, thinking you already have a stable car into the middle of the turn! Also, remember that the way your spoilers are set, your can be "uncontrollable in traffic"!!! 5) Cross weight: The lower the number on this setting, shifts the weight from the right front to the right rear!! This makes the car loose and easier to turn left, since you are unloading the right front tire. There is something you all should think about, a stock car a fuel cell that takes 22 gallons of petrol, right? Since gas weighs approximately 6.7lbs/gal, that equates to roughly 150 lbs. Now think a minute, as you gas depletes, a rear weight begins to lighten up causing you to "push". Hmm.. I will let you all think about that..: ) 6) Wheel lock: Well how do I put it?? Too much or too little is real bad, you just need enough to make a "hotlap or fastlap" or enough to be flexible in traffic. If you have too much or little you can be "over driving" your car!! Tires temps build up quickly!!!! Tire squeal is your number one enemy, besides the opponents on the track. ; ) Well there is a little bit from what I know about setting up car for NASCAR. I am currently writing a setup guide for NASCAR, Indycar II and Grand Prix 2. I have not gotten into detail here. In the guide, I will be very explicit and also technical. Since I do this alot..: ) Hint..Hint... The guides will be based on qualifying and race setups, lines, and utilities.. There will be NO track guides..Sorry, I feel there are alot out there that can point you in the right direction. The guides will be at the IVGA site as soon as I can get them done!; ) All of these guides are from my experience and hearing and reading about people's experiences in setting cars.. Any questions just email me.. take care..

One other point is that driving style has a LOT to do with tire wear. If you're cooking the RF tire, there's a good chance you're driving too hard into the corners for the chassis setup. You either have to modify the setup, your driving style or both. Dave (davids) Sparks Late Night League http://www.sequoia-dev.com/Hawaii/latenite.html
