Tyre pressure Hello! Last weekend I was at the track. Temperature outside was about 15-18 celsius (it's winter here)

check that all the doors and windows are closed as ac units do not work well when trying to cool the world
is the ac unit too small for the room size
I suspect that because it is working the problem is outside the ac control
is the inside fan working and blowing out cold air

Do you have normal fuel pressure and a good spark ?
Have you tried using starting fluid to boost the fuel supply ?

Replace the temperature sensor in front of the radiator.

Hello, any pressure in between is fine, these are recommended pressures, i personally look at tyre wear when putting pressure, if its wearing on the outsides it means it has not enough pressure, if it wears in the middle it has too much pressure, as a general guide 32psi is used at most tyre shops, extra 100kg does not make much differance to a 2 ton vehicle, otherwise you would be changing tyre pressure every time you fill up your fuel tank!!!!

the same as during the summer. look on your tires and test the pressure to see if it's close to the maximum psi, they are good, refill if the pressure is troo low.
the air is compressed when it's cold and expands as it gets hot. check your tire pressure every week and especially when the temperature changes like the cold winters and the hot summer.

The fridge should be just above freezing, maybe 2 or 3 degrees celsius. The freezer should be around -15 degrees celsius. The outside temp doesn't matter as far as the settings go.

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.,,,
