I took my s for a spirited ride yesterday for about 45 minutes and then chacked the tire pressure. the rears were at about 40psi and the fronts were at about 36-7 psi....are these numbers reasonable?

thanks

 

Mine are at 36psi all the way around cold. have not checked it hot, but will try to do that today. I usually run them at 34-37 cold, but i did have a period where they were at 38-40 cold.

As for the differing mileages we've been rporting, it may be based on some of the different driving conditions and road surfaces we find state to state and sometimes even city to city around here. unless we were all running the same route all the time, it would be difficult to judge. That being said though, Gilcwong and I run similar routes (except his extra 2 track days) and he got much worse mileages than mine...hmmm

 

yu888 - does Gilcwong run the same cold pressure as you?
You are completely correct about pavement not being the same and that causing different wear.

My overall thought is that I believe people run their tires too soft. I usually go 5 - 10 lbs below the maximum cold tire pressure stamped on the sidewall of the tire. I don't worry about wearing out the center of the tire because the way I drive I'm on the edges of the tires an awful lot of the time!

 

I replaced all 4 at about 17,500. The rears should have been done sooner (like 16,500 miles or so) and the fronts could have lasted a bit longer. When I lost the rear end while making a right turn from a stop sign at normal speed in the rain, I realized that I had waited too long to replace the rears. Fortunately, no harm done, but it was a wake up call.

 

I ran 34psi all around when I had the S02s. I'm running 35/34 front/rear on the Toyo RA1s. I drive pretty aggresively especially in turns

 

I just put on my 4th set with 20K miles. Wear has been identical for all three sets so far.

I run them at 39-40psi all around.

 

lower your pressure and see if that makes a difference

mine run 34 all the way around and im passing the 13500 mark with just the outsides of the rears fading away
