![]() There are some good studies to support that. On the other side is reported improvements in fuel economy and tire wear, but at the expense of ride quality. On the one side, the vehicle manufacturers and tire manufacturers point to the vehicle tire placard. There has been a long and sometimes heated debate about using inflation pressures higher than what is specified on the vehicle tire placard. The placard is usually located on a doorpost or in the glove box – but sometimes it is located in the trunk or on the fuel filler door.īTW, it doesn't matter who makes the tire or what pressure is listed on the tire's sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate. On every vehicle sold in the US - and I understand this is a worldwide practice as well - there is a sticker – commonly called the vehicle tire placard - that lists the original tire size and the vehicle manufacturer's specification pressure for that size. I will bump the pressure back up tomorrow and continue my quest of squeezing out a few more MPGs (and trying to teach my wife to do the same). but for this situation I'm just taking a deep sigh, and making a mental note for next time. Had they done this to one of my motorcycles, I would have been irate. Think of how much fuel savings there could be if instead up setting the PSI to the automobile manufacturers recommendations (for comfort), they'd set it toward the upper limits of the tire manufacturer settings. I can only assume they do this to every car that comes through there. I appreciate them watching out for me and had my tires been running 20lbs I would have been happy to see them helping me out, but that's kinda stepping on my toes. ![]() Yet they take it upon themselves to override my decision. I run a higher pressure because I often have a heavier load on them (multiple passengers, towing, etc), AND of course more recently. I have a REASON for running higher pressures in my tires. ![]() They dropped my pressure down to 36, which I'm sure it will be less when I check it. So I'm well within manufacturer's spec of the tire. Max tire pressures (44) indicated on the sidewall are COLD. I'm pretty sure they are measuring a HOT tire (which is going to be higher). I just found it odd that they would change the PSI without even asking.and, since I was quite confident that I accurately measured 41.5 to 42 psi in all of my tires, but they measured 45. I've never had any issues with this dealership and their service has always been spectacular, which is why I consider this to be a minor complaint. Sigh! I'm quite confident that this is a HOT pressure (also why they measured 45psi, it was hot!), and once they cool off, they'll be back down to 30psi. After she got it back, they had noted on the receipt that all four tires were at 45psi. My wife dropped the van off at the Honda Dealer for an oil change. Today, I got the answer to why my tires where low (or lower than what I was expecting). I set them all to 41psi-42psi (checked with a very accurate digit gauge). 30lbs? I was kicking myself in the a$$ for not checking sooner, but baffled as to how and why all four tires were this low. To my surprise each of the tires only had 30lbs in it. I normally run upper-30's and I thought I'd bump it up a little more. The next day I was looking for other ways to improve and decided to check my tire pressure. I might also point out that I had 7 people in the car (myself included). By reducing my speed (driving the speed limit, or just shy) and being light with the throttle on a recent 200-mile highway trip, I was able to achieve 26mpg. I've had a recent interest in shaving a few miles, hence my lurking in the shadows over the past few weeks, reading the tips-n-tricks, etc. My wife drives it most of the time (it's HER car), but I occasionally use it as a tow vehicle and whenever we go anywhere as a family, I'm typically driving. The entire time we have owned it, we've gotten about 20mpg city/rural and 22mpg highway, tops. I'll make my first post a complaint (well, a minor one).
