Stupid C.A.R.B. Regulatory crap..

[old-chevy-dude]

A little over a month ago I got a nail in my tire, nothing major, but enough to cause a small leak.

 

 

Being I was at the dealer for something else I asked them to patch it. $25 and on my way..

 

 

Well here in Sunny California, the dealers are required to change the PSI in the tires to the CARB regulations.. Well the damn dealer tech air'd down my tires to 30psi (@ mid day after I had just driven 45 miles and the tires were hot) I run my tires at 36psi COLD..

 

@ 36psi cold, the tires will expand to about 38-39psi while driving in mid summer when the temps are 90plus.. This keeps my mpg about 16.5mpg or roughly 480 miles out of 29 gallons of mostly city driving, and I've seen it as high as 19.5 on a 500 mile highway trip.

 

 

Since the day I had the tire patched I have filled my tank 2 times, and both times 29 gallons @ 380/389 miles or 13.1 mpg.. I was think WTF has happened to my mpg.. I hadn't thought to check the tire pressure after the dealer trip, I air'd up my tires back to 36psi (Cold, after truck had been sitting all night) and my AVG mpg in the DIC which has been at 13.5 for the past 2 tanks, immediatly came back up to 15.1 within 200 miles, and is still climbing..

 

 

Stupid CARB regulations..

I feel for ya Man.

 

I just had mine rotated/winter rims put on and told them to put it up to 38PSI (winter here). On the drive home it felt a little sluggish, so I checked the pressure and they were all at 32-33 PSI! Their guage was out of whack! I immediately aired them up to 38.

I had no idea that CARB regulations went as far as to regulating tire pressures. It just blows my mind that they are trying to help the environment with the CARB regulations but are actually doing the opposite!!! Nothing like lowering the tire pressure which results in increased fuel consumption!!

You ain't see nothing yet.

 

Fuel Economy Regs

 

 

Expect to see vehicle costs going up (by about $2,000 per car) if these fuel economy regulations go into effect by 2025. Oh, and expect to see a LOT more synthetic motor oil (0W-20, anyone?) in your future as automakers strive to eke every iota of fuel mileage they can out of their engines.
