I was wondering what psi other people were run in their jeep on the road and what size tire are u run

cruiser54

Search "chalk test".

Typically 28 PSI in the summer and 35 PSI in the winter for me.

Edit: And I have 33x12.50r15 tires.

Jesus dude.. speak English please. I run 35psi on the road.

This thread is beyond irrelevant. every tire is different. every jeep is different. need to do a chalk, dirt or water test. cruiser has the best info. no offense to you other posters but your posts serve no purpose without more info from the OP. like, what tires does he even have

thatXJguy

I'm not sure what's irrelevant. It sounds like you didn't even read the post; that, or assumed it was about something else before posting.

He's not asking what PSI to run in his own tires based on what we're running in ours, he's just asking what we're all running in ours. So I answered his question not only relevantly, but truthfully.

sycoglitch

youre right. i had to read his horrible english three times before i put it together. still curious as to his post and what hes really looking for but yea. there is relevance in your posts. i do wish the OP typed better though lol

I've been told that you shouldn't run higher pressure in the winter because as you drive the air in the tire warms up and expands, negating the effect of the cold weather.

the negative of running higher psi is the tire wont have all of its surface hitting the ground negating its sipping purposes. however, i feel when he goes higher in his pressure, the tire is cutting through the snow better.

atm I'm stock in tires (235/70/16) and run 29/30 year round. dirt and chalk tests show this to be my jeeps sweat spot. any higher and driving on dirt shows irregular marking

cruiser54

I run 110 to 120 year round.

Used to run 28 in my 35's and 10 offroad. Now with stickys I'll run 13-15 offroad.

It makes sense, but our tires lose pressure over time anyhow, so that negates the effect of filling your tires up in the Winter since by the time it warms up again, you'll have lost 5 PSI or so.

That's my theory, at least.

I haven't had any blowouts yet, but I do get good gas mileage.

I agree with you on the English bit. I really had a hard time understanding what he was asking.

8-15 offroad depending on what it is... my quick deflates stop at 15.

32 on on pavement year around.

Currently running 315/75/16 Duratracs but I do the same with everytire... I have never done a chalk test.

With my Wrangler MT/R's 32" 11.5 15, I run 26psi in the winter and did the chalk test, 34psi was good for summer.

When off road I run 11-13psi

unidentifiedbomb

I run 33psi all year with my 31 Duratracs
