Fuel Mileage Boosting Tricks and Tips that actually Work!

Ideally you always want to set your tire pressure with the tire cold or warm...not after driving them for over 1 hour!

 

Marcus, try your front at 32psi and rear at 30psi and see what the increase will be. The fronts will always need more than the rears due to supporting the weight of the engine and transmission!

Very true but one concern I have is that the max cold pressure stamped on the tire is 35 psi. If the pressure goes above 35 psi while driving, should I be concerned ?

I believe factory accounts for that, if you drive in Arizona for long time, the temp/ pressure would get high, they account for all conditions.

Monk is correct.
 
As long as you set your tire pressures cold, the normal heat up pressure increase is already factored in!
 
As well, ALL tires are rated the same way.
 
Normally tires can run at full rated load in lbs at full rated pressure in psi at the maximum allowed speed in km/h for 8 hours continuous driving...have you ever managed to drive at 120km/h without ever dropping below by even 5km/h??? For that matter, can your bladder make it that long????
 
In other words, There is a HUGE margin of safety built into ALL Tires!

Lol I find lately I'm always hyper focused on tire pressure , soon as backs go higher I deflate them to match, maybe this is why I bought it.....for the air filler ,hehe
