^^^^^^ +1 +5 +100000000 I couldn't agree with this more. In fact the best tire gauge I ever bought was a digital one from radio shack over a decade ago and to this day it spot on. A good tire gauge is worth its weight in gold, almost.Use a good pressure gauge to check it!!! I can't express this enough
I used to use a $6 Slime dial gauge that I bought at AutoZone 3 years ago. A few weeks ago my wife's Elantra felt really harsh after I put 36 lbs in the tires. On a whim I went on Amazon and got a good calibrated dial gauge... turns out that the $6 gauge was reading 15 PSI LOW! There was over 50 PSI in each of the tires.
