IMHO, while this is a great technique for track use, it's not that helpful for STREET use. It's like dressing for a January day. Do you wear the winter parka, or just the light windbreaker? Depends on whether you're going to watch a football game or going for a 5 mile run. Tire pressure for track use is different from tire pressure for street use. If your suspension is set up for aggressive track use (e.g., plenty of negative camber), you'll never achieve even tire temps across the treadwidth unless you are SERIOUSLY HAMMERING IT on the street (beyond the point of sanity). The only way to get uniform tire temps in that circumstance would be to lower the pressure so much you'll suffer major handling issues. Conversely, if you've got your suspension set for street/comfort use, if you do some hard cornering with it, you'll end up with uneven tire temps (hot outside, cooler inside) that you won't be able to correct for using pressure unless you crank up the pressures way too high. Bottom line, it's actually not that hard - just start with a set pressure, drive, and see how the car feels (given your standard driving conditions). Adjust up and down, and be happy with whatever you like the most. It's not rocket science, folks. P.S. for Chuckles, living in the land of long straight roads punctuated by periodic stop signs and 90 degree turns, he really should consider setting the car up so that he's not blowing through new sets of tires every 5k miles. vty, --Dennis -----Original Message----- From: LS [mailto:lashdeep [at] yahoo.com] Sent: Wednesday, November 07, 2007 12:40 PM To: Dennis Liu Cc: The FerrariList Subject: Re: [Ferrari] Tire Pressure for Aftermarket Wheels Go on a hard, curvy drive and have someone with a pyrometer check temps across the tread...when they are withing 5 degrees from inside to outside, you have the right temp.

I ask because of my TR. It had the metric wheels when I bought it, so I bought a set of 18" HRE wheels from Karl early on. They are obviously very different from the stock wheels in both sidewall height and construction, so I always picked the tire pressure by looking at the max rating on the tire and backing it down some (like if the tire said 51 psi max, I would run them around 44-46. This is very unscientific. I haven't seen uneven tire wear, so by that measure I assume it was OK. Is there a way to calculate the best tire pressure? Should I pick the factory recommendation from the 512TR since its wheels are nearly identical to my current ones in terms of size? I did Google the subject but only seem to get car-specific wheel recommendations. -- charles -------------------------------------------------------------------- Charles G.
