Tire warmers Are dual temperature tire warmers worth the extra $100 or are the single temp ones adequate? How long are you supposed to have them on before getting on the track? What is the optimum tire temp?

2 max pressures are printed on sidewall of all tires
1 for single (thats yours) and 1 for dual tires (cold)
The Tire dealer is the one who will know the recommended pressure for your tire brand, size and ply rating. my guess is around 34 psi. But, it really depends on the tire. - Alway check them cold for true reading -
* If the tires are the factory tires that came on the focus, the car dealership will know. - Service writer or Service Manager -

Because of changing outside temps this happens, just hold reset button on left side of dash until it reads tire pressure 100% again, just make sure your pressure is right before you do it. this is the same for oil changes and the like.

Hello partner. The difference in air pressure variations from a 16',17' or 20" tires is a non-factor. Any size tire will go up about 1psi per 10 degrees ambient temperature. The recommended pressure for an 03 Grand Cherokee is 33psi. So if it's a rainy 55 degrees in the great northwest when you set your pressures the temperature on your trip to Death Valley would have to climb to about 175 degrees. On a different note maybe your alarm just isn't calibrated correctly.

69,000 btuh is adequate for a 12-1400 square foot house.
Otherwise, your thermostat simply tells the furnace to cycle on/off.
If it calls for heat and does not come on, the problem is with switches and relays within the furnace.
Your setting the temp higher only causes the other parts to keep trying until they finally light and heat.
This is based on your information saying it will cycle on and blow cool air--not hot air.
You will have several temperature variations from floor to ceiling.
You probably have ceiling vents as well.
You need a technician to verify the rollout switches, fan relay, inducer fan etc. if the furnace is not firing everytime you call for heat.

Hi there. depending on the outside temperature of where you live , you may encounter this problem. If the temperature goes below -1 C , there is a chance that the tire pressure light will go on. This is because the pressure in the tires decrease in cold temperatures and will increase when it gets warmer. I had this problem with my vehicle too and when the temperature warmed up today the light finally went off.

so track was pretty cold too. I run rear tire at 28 psi and front 29psi. Coming off the track I had about 32psi rear and 31psi front. Pirelli SuperCorsa sc2 rear sc1 front. I had great grip and the bike handled very well. However I saw some pictures of my rear tyre and it looked very squashed, like too little pressure. Please have a look at the attached picture. Any comments/thoughts? The tyre temperature after sessions suggestest the tyre didn't heat up abnormally becuse of a too soft pressure. It's my understanding (after talking to other racers here) that you should use harder compound (sc2-3) on cold tracks and sc0-1 for warm tracks. This might seemd odd, but the reason being sc0 is design to run warmer, if you use it on a cold day, only the surface heats up but the carcass stays colder and the tyre surface can shear under load and you lose grip without any warning. A harder tire, sc2, will more slowly heat up and both surface and the carcass will more evenly reach same temperature and flex more uniformly. Any comments on this theory?,Wow! It does appear that the tire is bagged, good for drag racing or riding hefty chicks two up, but on the track...yikes! in my experience(4 years racing 600/750 superbike class), you can expect up to 10 psi difference from a cold tire to a hot one. I learned this lesson the hard way after not checking pressure on a set of new tires bought and mounted at the track that were at 40 psi. For the first few laps, I was flying, 2 seconds faster than my previous best at Nelson Ledges(Cleveland), but when the tires got up to temp, I was coming off the back straight into T12 and with no warning..I turned right off the edge of my tires. That single lapse in attention to the tire pressure cost me the championship(I finished 2nd overall...read:1st loser), $1000 in medical bills, and around $600 in damage to the bike. I typically liked to run 30 psi(f) and 31 psi(r) with Pirelli Medium compound.,,,
