Tire Pressure and gas

Chris,

I understand what you are saying about the chalk mimicing tire wear.

My point is that you are mimicing tire wear in a unrealistic way. What you are doing will show you exactly how your tire will wear in a parking lot at very slow speed, in a straight line with low tire temps.

How your tire wears under the above conditions are very different than how your tire will wear at highway speeds and normal operating temps.

As far as the dragster tire, I know that was kind of a extreme example. I was just trying to make a point.

With your above statement in mind think of the following 3 questions.
If you overinflate a normal street tire by 20 psi how will it wear?
Now if you underinflate the same stree tire by 20psi, how will it wear?
Now ask yourself, are you changing the shape/contact patch of this tire???

I respect your opinion and also the opinion of ridgerunner, they are just different from mine.... no harm, no foul.

 

Well maybe that is where I was confused. So you know a way to figure out the proper "cold" pressure for tires. I will remember that the next time I put a vehicle in storage. You did not mention "cold' pressure until the last thread.

Extreme, I asked three simple questions and you answered none of them. If you had answered the questions maybe you would have got the point.

Have you measured a street tire going 100+ m.p.h.?

This was me trying to be nice and agree to disagree.

 

Hey rac-you do Not express an opinion here. You criticise Chris' method. Then you offer No alternative method. Then you use HIS signature to slap him in the face as if to say "practice what you preach". Sure you are entitled to an opinion here! WHAT IS IT???? Sure you can critique Chris' chalk method! WHERE"S THE ALTERNATIVE METHOD YOU USE TO PROVE HIS IS WRONG???? If you cannot answer the two simple questions here, then you are critisizing just to be critisizing! Waste of time

 

These methods are what is common on the Jeep BBs as running oversize tires you can not follow the door sticker.
I have not done this yet on the Tacoma but they loaded the tires at 29 and they are too soft for sure.
Now they ride really nice but I can tell by looking they are low for the weight they are carrying.
The new nubs on the tires wore off on the outside first

 

I know I should stay out but here we go.

The chalk method works because if you check your tires frequently. No matter how your tires wear when you check them in the mornings with the chalk method it will show how they have worn for the last week no matter how you drive, then you compensate your psi to accomadate the shape your tires are taking.
It is just faster to chalk your tires then to walk around looking at them and trying to figure out what psi you think should be in them. That is my take on the whole thing. I agree with all parties here seeing as how there is almost always more than one way to achieve the same answer. Thanks for the input I have learned a bunch here, and will be applying it to my truck form here on out, wether it increases my mpg or just the life of my tires.

 

WHAT??!! ARE YOU SERIOUS? HOW DARE YOU..just kidding now get outa here LOL

 

I'm back and according to me and only me I went from 60psi to 50 in front and 53 in the rear. whew.

 

luk whats your max tire pressure allowed on the sidewall?

 

65psi max if i'm not mistaken I usually run 5lbs less than what the tires call for.

 

WOW-Ive never run across tires w/ that high a max-just curious

 

BFG T/A KO 65psi max cold. 33"

 

Whats the deally w/that Chris-does it take that much to "fill out" that tire's construction? How come mine are only 35?

 

Shoot I shoulda figured that-Im gettin senile Thanks Chris.
