Tire pressure / Chalk test - Jeep Enthusiast Forums
2007年10月30日 · I know that this topic has been discussed over and over again but I had a question regarding the chalk test for getting the tire pressure set correctly. I just put on a set of 35x12.5 Mickey Thompson MTZ. This pic is the tire at 22psi. Looks over inflated so I took it down.
Chalk test?? I'm not driving at 16 PSI!!! - Jeep Enthusiast Forums
2012年2月26日 · Wider tires will crown on narrower wheels. The chalk test is designed for tires mounted on wheels that are just about as wide as the section width of the rubber, so the sidewall is practically flat and vertical instead of bulging. So you'd need 10-12" wide wheels to get an accurate chalk test on 12.5s.
Chalk test hot or cold? - Jeep Enthusiast Forums
2015年6月11日 · As the title says I'm trying to figure out if I should chalk test the tire hot or cold. I've did a little searching and can find tons of info on chalk testing but haven't seen it mentioned if it should be done hot or cold. I would think you would do it when the tires are hot since that's the pressure they will spend most of the time at.

Best tire pressure for 35×12.5×15 - Jeep Enthusiast Forums
2022年9月7日 · X2, the "chalk test" is not foolproof, it needs experience to interpret properly. The vast majority of those trying the chalk test at the recommendation of others end up with severely underinflated tires. For a 35x12.50R15 supporting a TJ, 24 is good when the TJ is lightly loaded, 26 psi is good when it's fully loaded on the highway.
how do you preform the 'chalk test'? - Jeep Enthusiast Forums
2008年7月25日 · The easiest is to try to slide a thin card under the edge of the tread. Inflate the tire until you can just get the card under the edge a little bit. A more involved check is to place a chalk line across the tread face, drive a short distance straight ahead on a smooth surface and then observe the chalk line.
Chalk test for PSI; is it accurate? - JKOwners Forum
2012年5月30日 · Chalk test shows how the tire is touching the road, it's pretty accurate. What pressure to get a flat pattern is also dependent on your rim width. The wider the rim, the flatter the tire will be at a given pressure compared to a narrower rim. Is this "slight" wear measurable? I suppose I'll be the first to say balance and rotate mud terrains.
Tire Pressure On LARGE Tires | Jeep Enthusiast Forums
