Kizashi tire pressure. Why so high.

Anything related to the Kizashi can go here, but please look at the other headings first. Your topic may fit better under something else.

Another reason is load rating. You have to have a certain pressure to meet a certain load rating. Most of these load ratings don't increase linearly, so we don't know what pressures may be required below the max inflation spec.

Case in point, we need to run 44psi on our snow set of General Altimax Arctics to meet the load rating of the GVWR of the car.

Mileage and ride are huge factors too.

Bottom line is run what you want as long as you are within the load rating spec. TPMS may bother you, but then you can do one of the several mods to fool the car. I still need to just make a tpms simulator box for the car...

Hey KuroNekko! Work has been completely crazy. :cry: I've been meaning to get on here for months, but haven't hardly had time to breathe. In fact, I was supposed to go to bed an hour ago, but saw another thread reply email notification and just had to check it out. A hour later, I'm still here.

I missed being here! Looks like we got some new members too! I'll try to catch up in the next few weeks if I get a chance. 8-)

Just aired up last night...I could feel the handling getting poor. Checked them and they were at 37 lbs., aired back up to 40 all the way around. Nice and tight again.

Yes, a lot of it will depend on what tyres you're running.

I find just under the recommended 38 best for ride and handling, but if it drops below around 34 the handling suffers. That with 235/50R17 Pirelli P Zeros.

Glad your back. Thought you might have gotten rid of your Kizashi, last I remember you where having problems.

Good to be back. Nah, if I ever get rid of it, everyone here will know here first. There's no major problems that I know of, but since I'm a perfectionist when it comes to my cars, I know every little ding, dent, sound, scratch, or slight imperfection--and that list can be long.

So what I was alluding to was a box that you can plug into the power outlet that emulates the signal from the TPMS sensor. This way, you always have perfect TPMS pressures and can just use regular tires.

Is this box a wish or does someone make one?
