That would be a good start... I was poking at him a bit there. Most decent gauges are pretty accurate, but not always right on the money. The entire point was that one pound either way is not going to alter anything at all. Not sure I've ever run into anybody being quite so anal about tire pressure to the half pound.unless you get several different gauges and compare their readings to each other and to the TPMS reading .
I also set my tires with this same gauge. I misplaced the nice chrome digital gauge I used with the '07. The other day wife found the chrome gauge in her pickup. I'm looking forward to comparing them soon.I have an Accutire MS-4021B digital tire gauge which displays in 0.5 PSI increments and found the TPMS to be within +/- 0.5 PSI of the gauge.
I would go back and get my 20PSI (4 tires x 5PSI)Drove to work yesterday's morning and saw a screw in one of my tires.
It wasn't completely flat. TPMS said 28.
So at lunch time I drove car to this shop that I had called before that said they'll put nitrogen in 4 tires for $20.
Took it there to have the tire fix and while at it have nitrogen put in 4 tires of my car.
Bill came to be $50!
$20 for Nitrogen, $15 for fixing nail in tire and $15 for balance of 4 wheels which I didn't ask for. If rebalancing was necessary, they should have told me that before and not surprise you with it.
Regardless, I paid the bill and tip the guy who worked on my car.
Also I had asked for the guy to put in 40 PSI, higher than tire's manufacturer recommendation because I like the gas savings you get from it. The guy expressed some concerns saying TPMS warning lights might come on. I said not to worry because I have been driving on 39 PSI since I got the new car off the Toyota's lot 2 months ago. They were no warning lights to worry about.
So the guy said okay, he'll do it.
After I got home, I checked the tire pressure, its all at 35 PSI and not 40 per my request.
I was watching as best I could from customer area when the guy was fixing the flat tire. It appeared that they did a good job to make sure the nail hole was fixed for good.
One last complaint, my car is brand new so I think they should have been a little careful. I found black smudges and dark fingerprints inside of my car at driver's door and at glove compartment (they had to get the wheel lock).
To help others, I will comment in Yelp and perhaps avoid this place.
Discount tire also included the free rot and bal when you buy a set tires. No nitrogen at discount that I know of. The rot and bal is probably hidden as a discount in the price of a set of tires. I have heard they fix flats for free and do free tire rotation. If so it's to lure in more customers for possible future tire sales.I believe for a tire bought at Costco flat repair and wheel balancing are free, along with nitrogen filled.
Costco will rotate and balance every 7,500 miles free for life of tire, in addition to free repair.Discount tire also included the free rot and bal when you buy a set tires.
