DScottM Posted May 31, 2012 Report Share Posted May 31, 2012 Yep, I know people always say that's a high pressure to run at. However I like the firm ride and added steering response with the higher pressure. I had a feeling I should have dropped the pressure down to the high 30's before hitting the track, but I wanted to see how they did at this pressure. My guess is they only went up another 1-2 psi from driving. And like you said, I truly feel that it was more of a launching/bogging issue resulting in my times. 40 is quite high, i work in a tire shop and have done lotsa stuff with different stuff haha. 35-37 is tops i would run around every day. at 40 you will be wearing your centers of your tires out. i am currently running my Cooper Zeon RS3-A's at 30 because the normal 35 was too high. We will see i guess prolly end up around 32. Track you could easy run 30ish at the highest... Just my imput :) Link to comment Share on other sites More sharing options...

I am pretty much kicked on mine and I did enjoy them but now that they are on coming right up to the wear bars... they feel very on edge to say the least. I assumed that as tread wore down you would SLOWLY lower the pressure (1-2 psi) as well but I am still on edge but if I go much lower the tire looks flat (although its not) and sorta holds the road like a floppy cock time for something with more punch then a 16t Biggest little 16T in the world upgrade?

Running 235/45/17s which are too big haha, next set im dropping to 225/45/17s. Just rotated the tires for the second time at 6000 miles, All worn evenly at about 7-8 32nds left. Keeping preasure at 30 for now prolly wont go alot lower than that... Link to comment Share on other sites More sharing options...
Keep Calm Chive On Posted July 17, 2012 Report Share Posted July 17, 2012 Welp... I must drive like a prick then cause I swung only 20K out of the tires. I will say they were awesome while they lasted but for that 45K mile warranty... I'm getting 56% back (when I have a job that can pay for it) 30 in my book is too low but to each their own. Have you done the whole puddle print test? seeing how much contact patch you actually have? It's not perfect but it can show you what is too low and what is too high then sorta just take the middle ground from it. I think I have mine at 35-36 cold all around. I believe that even my pocket data booklet lists it right at 33 although that is 205/45/R17 but again that was as close as what was actually listed. That listing is for speeds under 160kph & I believe its 41.3 or something like that for speeds OVER 160kph... THESE ARE NOT EXACTLY WHAT IS IN THE POCKET DATA BOOKLET!!! but I can confirm them tomorrow afternoon Also here is a guestimator for MOST passanger vehicles (Vehicle Weight) / 100 = ? +/- 2 Psi so 3300 ish / 100 = 33 psi (I prefer a bit extra) Link to comment Share on other sites More sharing options...
DScottM Posted July 17, 2012 Report Share Posted July 17, 2012 Hmmm 35 or 36 wears your centers out big time. That y i dropped mine back... Link to comment Share on other sites More sharing options...

s_moneh Posted July 18, 2012 Report Share Posted July 18, 2012 is 12,27 really the fastest time for the volvo crowd right now? :( Link to comment Share on other sites More sharing options...
fischmama Posted July 19, 2012 Report Share Posted July 19, 2012 is 12,27 really the fastest time for the volvo crowd right now? Prob not...my trap speed is right at number 2 in the list. Waiting for my gripper to improve that (will hopefully arrive next week). Link to comment Share on other sites More sharing options...
854TGA+ Posted July 20, 2012 Report Share Posted July 20, 2012 Prob not...my trap speed is right at number 2 in the list. Waiting for my gripper to improve that (will hopefully arrive next week). I am in the boat Justus, just waiting to get my boost issue resolved and then back to the track. I ran the same trap speed this year (111 mph) as last but with 8 pounds of boost less. I really want to crack 120 mph 1/4 this year. Link to comment Share on other sites More sharing options...

fischmama Posted July 20, 2012 Report Share Posted July 20, 2012 Wow, I am @ 18psi now hoping to get back up in the mid to high 20's again (GT3071R) Just to be clear I ran the 110mph trap at 19ish PSI on the 60trim. Not that someone thinks I did that on 12-13PSI. hah Link to comment Share on other sites More sharing options...
