Tire size again??

[roostthemoon]

Can anyone tell me what the actual tire size is for a 37x12.50R17 BFG All Terrain?? Im looking for what the size says on the sidewall of the tire. I want to purchase some from discount tire but they only have the sizes that way and I dont know what they mean..

Thank you,

diameterxwidthxrim size

its not rocket science

[roostthemoon]

Yea I know what 37x12.50R17 means. That is in inches and I live in america so I am able to read that. What I was asking is the numbers on the side wall that is in millimeters (which comes from a country that I dont live in) which I dont understand. I want to know what NUMBERS are equivilant to 37x12.50R17 so I can order them off the internet.

convert the units.

you the flatbiller that was driving that ranger up and down rockpile at the nightrace?

The actual tire size on a 37x12.5r17 is exactly that. In metric would be 317.5/80r17 which to my knowledge doesn't exist

http://www.discounttire.com/dtcs/findTireDetail.do?rcz=92320&rc=CRCINT&cf=false&c=1&sw=false&cs=37&pc=38073&rd=17&ar=1250&tc=MTAVL5&rf=true

Although I don't know why you would want A/T's that big.

No that was my buddy, why??

[moabWalker]

BFGoodrich's site has exactly what you are asking for.

http://www.bfgoodrichtires.com/specs/all-terrain-t-a-ko/44.html

its a spec sheet; 1st column tells you what the sidewall says, seventh column tells you actual O.D.

[grantdcol]

Its not that clear how to convert.

Metric size is like this: Width (mm) / Sidewall Ratio (% of width) R Wheel diameter (inches)

So you divide the width by 25.4 (millimeters per inch) to get the width in inches.

The you multiply the width in inches times the sidewall ratio to get the actual sidewall height in inches. Then double the sidewall height and add it to the Wheel diameter, and that's your tire diameter.

Fun huh?

Ok heres one last question while we are on the subject of tires. I just picked up my tires today and they are 12.50R17. They will fit on an 8'' rim right? Or do I need an
8 1/2'' rim. I want to know before I buy rims.

[Bulldozer]

8" will work fine. Some tire places won't mount them though, so try a small family owned type shop and they'll usually do it without a hassle.

[roostthemoon]

But according to this site, http://www.bfgoodrichtires.com/specs/all-terrain-t-a-ko/44.html I have to use an 8 1/2. Or is that just for saftey reasons??

[roostthemoon]

I just found this page too. http://www.bfgoodrichtires.com/cutaway/all-terrain-t-a-ko/44.html It had some cool info that can be very useful. Got to the link then look toward the bottom right of the page. You will see a yellow F-150 with "Off Road Tire Size" next to it. Click on that link. Good stuff. I think

[Bulldozer]

I'm not gonna lie I didn't read either of those pages...

But there are plenty of people out there running 12.5" wide tires on 8" rims.

[Stonehouse]

so from going from 35's to 37's you only get another inch clearance from the ground to your diff. i forget the price diffreance but is it really worth it...?

321$ each vs. $176 each from discounttire.com

you could get 6 35's for the price of 4 37's.

Oh, and 6 37's will run you 2 thousand freaking dollars.

A little ridiculous in my opinion. :rolleyes:

[jeff]

I paid $1K for 6 brand new 37" Projects (Kevlar race tires). Watch the RDC classifieds, they get posted and then they go QUICK.

There are many ways to address this question about if 37s are really worth it. Yes it does seem worthless to pay so much more just to get one inch more ground clearence, but there is more to it than that. This is where you need to think outside the box a little. You can look at it many ways. Say you put a TT with 15inch tires up against a TT with 37's. Whos going to win???? Umm the TT with 37's. (THATS IF TYHEY BOTH DONT BREAK) Now the question is...Why?? Just think about it. How much rubber is actually touching the ground on a 15in tire compared to a 37. Not much. The 37 has it beat by a long shot. Now if there is more rubber touching the ground then that means you are getting more traction, and more traction means more speed....so on and so on. Now think of a 35, yea it is not much smaller than a 37 but that little bit does help. That is just that much more rubber touching the dirt. Now if you are going to buy big tires to put on you prerunner and want it to look good. What are you going to get. Is it just me or do 33's look small and kind of funny on a ranger with glass?? Most people would run 35's to help fill the fenders. Now say you have a fullsize truck. Are you going to get 35's. Maybe. But some may think that 35's are too small to run on a fullsize with glass and would prefer 37's to fill the fenders. But that is just my opinion and that is one reason why I love america because I am allowed to have that opinion.

I don't think 35's look small on a ranger :/
I I don't know about you, but the extra weight and broken parts and insane cost difference make the 35's a lot more appealing to me

[roostthemoon]

If you go back and read it one more time it says, "Is it just me or do 33's look small and kind of funny on a ranger with glass?? Most people would run 35's to help fill the fenders". I dont think 35's are too small on a ranger either!

Whoops, my bad.
Either way, I'd go for the 35's unless I came across a set of 37" projects really cheap.

But, I'm not a fan of huge tires, my last truck had 32's and my next truck will have 33's.

[roostthemoon]

What ever works for you is best. Dont worry about what others suggest you get.

[fatnbald]

No that was my buddy, why??

because running your truck up and down the course durring the race makes you and or your buddy a douche.

Is that your opinion or somebody elses? You said it both ways. And which country won't let you have an opinion on tire size?

How about running the tires that work the best, not the ones which fit your fenders.
Better yet, fit your fenders to your tires.

I think you should 44s on it you would have all traction you need then the bigger the better!!!!!!!!
