If you provide the tire size, maximum inflation and load stamped on the tire sidewall, as well as the front and rear ‘GAWR’ figures off the build sticker next to the tire and load sticker, I can calculate your recommended cold pressures for your non-OEM, aftermarket tires.
If there is a ‘P’ in front of the tire size, EG: P215-60R16, please include it. If not, exclude that P.
Haven’t had the chance to reach out yet. I will when it gets closer to time for new tires. Got a screw in the sidewall and that messed my plans up as I didn’t have money for the whole package with the wheels at this time.
My point is that manufacturer has provided tires that are too low profile in my opinion. It’s whatever is on them when they come from factory that’s “specified” as far as I know.
Can you expand?
They are pretty low. If I go down to 16" then I’m already out of spec so I don’t see why I’d follow the spec for the other so long as I’m not putting something really heavy or with a lot of angular momentum farther from the center of the tire.
The door jams is labeled toward the stock of factory wheels and tire size… when we went from 16’’ wheels to 19’’ wheels the tire wanted my suggestion as to how much psi to put in this newest. I told them 45psi. but after a few months we aired down to 43 psi as this seem to be better and allows the tire to make full contact. With the tire being at 45psi, we we’re riding on the center tread which it designed for winter use… so airing it down place the outer edge of the tire closer to the road. the outer edge is designed to take on wet and dry weather driving. it only been 2 weeks since airing down to 43 psi so I can’t pass judgement on if this the correct psi for our driving habits… but it does feel sluggish at time… just down want the van all over the road drifting due to deflated tires.
I tend to find myself all over the road when the tires are over-inflated, especially with wider, lower profiles.
Remember: Narrower, taller sidewall tires tend to track straighter, even with some deviation from the cold pressures on the vehicle door pillar.
Wider, lower profiles want to go sideways, and are more responsive to steering input. They are also more sensitive to deviation from the pressures specified by vehicle manufacturers.
If you review my post, you will see that my reply was to @LostnTransit’s post, not the OP’s question of “Will changing…”. The number of users on this forum that feel the need to nitpick other users posts is unfortunate. And, apparently for no other reason than to make themselves feel superior since it adds no value to the discussion. If your desire is to help others, then great! The rest is just needless quibble.
That’s an inch larger than stock diameter/height. If everything I typed into “Discount Tires” calculator was correct.
Thanks for the post @llialyn. Note that the posts you responded to are a year or more old. If you aren’t aware already, the dates of the of the posts are in the upper right corner of the box the response is in. Usually older posts don’t get much traffic. You are still welcome to respond to any post you like though. Welcome to the forum and I hope you come back and join us again.
Why does the age of posts matter so much?
Why do some folks feel the need to point this out?
People need to know that they are replying to an old post so they will know that their post may never be seen by the original poster . Especially the ones who ask if the person ever solved their problem.
It is an opportunity to chase away new members.
What a tragedy. On the other hand, this thread has been viewed 14,900 times, it doesn’t exist solely for the OP.
Who gives a tihs if it’s an old post or thread??
Like I said, what you can’t seem to get through your thick skull is that as long as a thread contains useful information, it matters not whether it was started ten minutes, ten months, or ten kreldan years ago.
I’d rather see people use the search function, and contribute to a thread relevant to the topic they’re searching for, “oil viscosity” “tire pressure” “transmission slippage” or whatever, than created a thousandth thread about the same subject.
Thank you, walls, for listening to this rant, because the individual I’m replying to sure ain’t!
Welcome to the forum… Feel free to ask questions or help out when you can…
I do it to help a new poster figure out how to navigate the site and then welcome them.
jt how does telling someone they are “replying to an old thread” help them to “navigate the site”?
I’m not following the logic here.
By telling them how to find the age of the thread. Posting a question or comment to an old thread can sometimes be useless, if the original poster hasn’t been back in years. Sometimes useful, if it supplies information on a topic that could benefit folks today.
Plus, posting a new topic gives everyone a fresh start and we don’t have to read through 100 prior post about air pressures and toilet paper and blah blah blahs just to find out how to check a wheel bearing or whatever…
Some moderated forums actually recommend searching for, and participating in, existing threads about ones subject before creating a new thread.
I agree with that policy, even if I’m the only one on CarTalk that does…!
