I had to get new tires the other day and they had the pressure in all tires a bit high and none of them the same.

So I waited until the next morning (when things were cooler) and checked (ea tire lost a little which I expected) and set everything to 35psi. I know that change in outside air temp. plays with the psi. But during the summer should you set it different then during the winter?
 
No. If you set tire pressures when the tires are cold(not in direct sunlight either) the ambient air temp shouldn’t change anything. You see pressure changes on the days we get a 30 degree swing but not enough to matter.

It is the temperature of the air inside the tire that matters. Ambient air temp changes that, but not to the same extent as the friction from driving. A change of 10 degree F is about a change of 1 psi.

In summer I try to pick a morning that is about 75F and in winter (here) I pick a day that is about 55F.

It's almost time to switch your battery cables around, so the heat starts workin and the A/C stops.

I will...

Soon as I’m finished driving in reverse to roll back my odometer. :cool:

Come on...that’s a trick question.

1,000 pounds of lead. :cool:
 
So I'm at work at the shop I used to work at and this older feller comes wondering in carring a portable air tank. He askes "can you put some air in here for me"? Sure why not. I go to the tool box grab my air chuck and start filling the tank. I ask him how much air you want in here, about 100 pounds? He says "Lord Jesus no I cant carry that"!

Must have been related to that customer at the pizza restaurant. Counter guy asked him whether he wanted his pizza cut into 8 or 10 slices. Customer answers, “8 please, I’m not hungry enough to eat 10”. ;)
 
True story,, couple old guys were sittin outside the service station in Greeleyville and this 20 something hipster rides up on his pedal bike and proceeds to the air pump. Just before he is going to put air in his tires, one of the old guys tells him that there is car air not bike air. The hipster laughs and presses the air to the tire. A second later, like a gun shot, the tire explodes. Old many says, toll ya boy. Hipster says, you did; he was never heard from again.
 
I just check my tire pressure ~ once a month & adjust accordingly. Not messin' with ya, but it ain't rocket science. My bike doesn't roll without checking the tire pressure.
 
…………I set tire pressure once in the late fall (once the temperature drops or when I see the sidewall sag a bit) and once in late spring or so (once it gets up in the upper 80s's).

You must switch out the humid summer air for less humid air on October 31st. Then back again on 4/1.

I actually convinced my wife’s sister ask for the air to be changed when she took her Prius in for regular maintenance. I told her she needed (which she really did) a 4 wheel alignment along with the wheels balanced and rotated. Being the SOB I am I told her to make sure they changed the air in her tires and put new fresh air in. She did and the message she left on our answering machine stayed there for months so we could laugh at her tirade when the service rep told her someone was messing with her.

Okay, so how about 1000 pounds of feathers vs 1000 pounds of gold? ;)

Feathers. By several hundred pounds. ;)

Side note ... last year I bought a case of antifreeze and my BIL asked why I needed so much antifreeze. I told him I had to replace the tires on the tractor and needed antifreeze. He got the WTF look on his face and asked why I had to mess with antifreeze if I was just changing tires. When I told him I filled the tires with antifreeze he didn’t believe me. I had to have him go in the interweb to actually see you can fill tractor tires with an antifreeze mix. Sometimes I actually am nice to idiots.

Wait for a day the temp changes quickly and you can show him the level it is in the tires by the condensation line and really blow his mind.
 
Do you know what tire is best for keeping pressure?

a Goodyear!

do you know why?

each Goodyear tire is made from 365 used condoms melted down and recast as a tire.
 
Guys...
Don't forget to change your BLINKER FLUID to the winter one!!!

Seems like an unlikely story. Car tires run about 32 psi. Bike tires 95-110 psi.


Plus.... hipsters are probably running Presta valves, and can’t use the Schrader chuck at the gas station. ;) :D

Let us not let facts get in the way of bashing cyclists...

When I got my mountain bike a couple years ago I was shocked when I saw the tire pressure that's recommended!
