Re: Tire Pressure (Fevre)
Posting again so you don't get a blow out, check the tires, the recomended psi should be on them.

I think you will find that the MAX PRESSURE is what is on the sidewalls of the tires. Don't run on MAX PRESSURE! Tires need to be inflated depending on the weight/vehicle load. Think about it - it would be next to impossible for a tire manufacturer to state one tire pressure on the tire knowing that many different vehicles could use them. They'd be sued for sure!

So should he run it at 20? :confused: True it states the max (just checked all 3 of my vehicles, vette states 35, Formula states 40 and Sonoma states 50) but I would use that as a starting guideline before anything else. How could the vehicle manufacturer know what tires (and rims) you are going to put on it after the originals wear out? Catch 22, refer to the tire not the owners manual of a 30 year old car IMHO.

Re: Tire Pressure (Brent Brooking)
The radials of the 70's were of a stiffer sidewall and were made to be used on all the cars of the day. The Corvette was one of the lighter cars being made then, even though we think they are heavy now, so 20 lbs for the tire pressure gave good performance and helped the tires to "stick" when cornerning. Can you imagine putting 35 lbs in a 70's radial and taking a corner? You'd be slidding in circles.....

Check the tires, specs are usually on them.

Note that I did say "Tires need to be inflated depending on the weight/vehicle load." If you use the MAX as a starting point you are going to be overinflating your tires and they will wear quickly. Best to check for tire pressure by vehicle weight with the tire companies. I would not run more than 30-32 lbs on my Corvette's tires and expect to get good wear.
You will not find any tire company, etc. that will recommend inflating your tires at the MAX pressure.
Good luck!

Just in case you where unfamiliar with the def of guideline:

Re: Tire Pressure (wogs73)
OK as long as we are posting This is what I was taught take it for what it is worth . Start with 32 psi then mark the tire tread with paint or chauk or something similar. Drive car around the block if the paint is all gone you are good if there is more paint left in the center of the thread add more air psi if the edges have paint remove some psi. This way you have the largest contact patch. That said I run 26 on the rear and 28 on front this also smothes the road out alittle bit

Get a grip on what you said: "starting guideline" So you think we should start at MAX and work down? Doesn't make sense to argue this point with you anymore.......

Wow ken, you sound like a little school girl. When is the cr fight gonna be? You need to grow up man.
And milo, reguarding your technique. Is that after the tires are warmed up, or cold?

Re: Tire Pressure (MILO851)
MILO851,
what does it do in the 1/4 with the blower. I assume you put some sort of hood scoop in?
I have to run around 20-25 pounds in my Indy 500s else they ride like rocks.
