revs per mile

[XJSuperman]

It's not a mtter of being lazy. Over 50,000 miles a . 3 revolution variance equates to 24 TOTAL miles... . out of 50,000. That means that over the life of a set of tires... IF they last 50,000 miles... you're off by WAY less than 24 miles... because the variance doesn;t occur until significant tire wear happens.



You call it lazy that we want a simpler way to do something... I call it asenine that you are worried about so few miles over the course of hundreds of thousands. Do what you want I for one am not going to measure my exact tire diameter every 10,000 miles... again asenine to determine within a tenth of mile how many miles are on my truck. If the tire manf says 601... 601 it is and I'm not going to change my revs in the computer every single time I put a new set of tires on. Yes... if I go from stock to larger or smaller tires by all means I will... but 601 is 601 is 601. Quibble about . 3 revs if you must be asenine.

Hey man, I didn't mean for you to take it personally. I summed it up in the last sentence of my post... different strokes for different folks. Some of us like to be told "it's this, do this, go here, blah blah" and some of us like to figure things out on our own and not take other people's word for it. With the knowledge on these boards, there's enough info for any newbies to pick and shose the method they want. You can't deny that the "hard way" will work just as well as looking at the manufacturer's website, but for some people maybe putting a dab of marking compound on the tire is easier than using the computer. To each their own... and at least I never called anyone assenine, nor would I consider anyone who's trying to be as accurate as possible assenine... maybe a little anal but so what? I thought we weren't supposed to resort to name calling on here.

Asenine and anal pretty much mean the same thing. And I did not take it personally... but it seemed the 'hard' way was being argued ...common sense says if their's a hard way... and a simple way to do something... and they are BOTH correct... then the simple way wins. No question. . ESECIALLY if you are a newbie. Why would anyone who is new to this want to go through several calculations... whether or not they know how to use a computer is irrelevant... if they are here they know enough to search the web.



If you took it that I am calling you asenine then I do apologize... never my intention to do that... just your methods for this particular thing... as I said before... why complicate it.



I never said your way is wrong... and my way is right. I am simply trying to say KISS. Keep It Simple Silly

... and then there are those cases when the manufacturer doesn't list the revs per mile on their website. Then what do you do? It's like when in school and the teacher says "do it on paper" and you say "why, because I have a calculator"... if you know the 'hard' way to do it, you won't have to rely on the easy when when it's not available.

True... but it's also easy to make a phone call to any tire store who sells them and if they can;t help they can get you the tire manufacturer's phone number as well. But keep going you almost got me convinced :-{}

Hahaha yeah and that'll take less than the 2 minutes it takes me to mark it out on the garage floor.

The most accurate way to figure your revs per mile is as follows. Get your tire pressure set at the pressure you normally run. Load your truck as it is most often loaded. Park the truck with the valve stem of one of the rear wheels at the extreme bottom. Mark a line on the ground with chalk. Roll the truck forward one full revolution of the wheel and mark again. Measure the distance and do the math on one mile (5280 feet if I remember correctly). This is the only way to get an accurate number. Revs per mile change with tire pressure, payload, and tire wear. This is how us cyclist set the computers on our bikes.

One dealer quoted me $39. 99 I balked saying it barely takes 15 minutes and he dropped the price to $19. 99



Then a week later a friend leaves a message on my answering machining telling me he had his done at a really close local dealer for free.



Set mine to 601

My program is rough but I think it is a little better (well at least it is a little more written for Dodge/Jeep owners... )

I have a lot of work to do but I am lazy. . Let me know what you guys think.
