Tire Pressure...

I have a staggered set and run 33F 40R.
I've had STS set them all the same at 35 before and Benz set them at 30F 35R. So I kind of just go with what I feel most comfortable with. The weather is so inconsistent up here so I often have to put more air in it every few months.
Anyone try nitrogen?

I have staggered setup as well, and I run 35 all around. As far as designer air, I don't need it, the small benefit of nitrogen is not worth the trouble of filling up at a nitrogen station only.

Good question. I just thought it(Nitrogen) would keep the pressure from changing due to temperature drops etc. I swear during an 20 degree drop in temp that the PSI seems to drop 5-8 area. Which is enough to set the alert off in some cases. I check it daily just in case but some days it'll be about 90 during the apex then late night or early next morning it's easily 65-70.

Regular air is 87% nitrogen, Nitrogen is a gas and is still affected by changes in ambient temperature (about one psi for every 10° Fahrenheit). The benefit of nitrogen is that it is less likely to migrate through tire rubber than is oxygen, but again, there is only 20.9% of oxygen in air. Nitrogen tends to be dryer as well, less moisture, which is another small percentage. If I track my car, I would most definitely use nitrogen, but since I do not, the trouble of topping off my tire with nitrogen out-weights the benefits.

I bought a 2014 VW that had nitrogen "installed" in the tires as part of a dealer add-on package in Dec. of 2014. I check the pressure every 5,000 miles (6 months) and almost 2 years later it still has the same 32 psi it came with. I was so impressed I've put it in the tires on all my rolling stock. Cost is $20 for most sedans, vehicles with staggered tire sizes (E-350, Corvette, etc.) are $25. Best automobile value I've encountered in a long time and I have a compress installed in my garage.

These crappy roads in central Massachusetts force me to stay at about 35 all around to avoid another flat due to pot holes.
So far so good.... comfort is perfectly fine.
