I know similar questions have been asked, but I couldn't find a definate answer to my question. Going by size what is taller and skinnier, 245/70-17 or a 265/70-17 Isn't it the first number is how many milimeters wide and the second number is percentage of that first number indicating sidewall heighth?
What I want is a tall but skinny tire, like a lot of the earlier Fords have, but will fit on my 06 2500. Thanks for any info.

Here is a link to a tire height calculator. http://www.ringpinion.com/Calc_RPM.aspx

Looks like the 265 is taller by about an inch.

BFGoodrich makes a 245/75/17 load range E.

I think the 245/75 is actually a hair shorter then stock if i remember correctly. I had to jump up to a 285 to get the tire hight i wanted.

Well these were the skinnest and tallest I had heard of: BFG M/T KM2 (only 255/80r17 size.... I they were E rated and cost about $200 a piece.

You only need 19.5" size rims

So, I like the idea of going from a ~31.4" diam. tire to 33.4" - how do I correct my speedo/odometer? Can the dealer flash the ECM for the correct size?

Those wouldn't fit my 17 inch rims correct?

Totallyrad

Yes.......

Actually no, the dealer cannot flash your truck for the correct size. The highest the dealer can go with your truck (an 07) is for the height of a 285/70/17 tire, which is the stock size on the Power Wagons. The height of the 285's is about 32.7 inches, so you'll still be off a bit.

The 2004.5 and 05 trucks speedo can be corrected by revs per mile; I don't know if there is a 'max' number. The 06's and above can only be corrected by tire size, or max revs per mile of 617, which is what the 285/70/17's are....

Someone chime in if I'm wrong here, but that's the last information I had...

Totallyrad

You may be correct.

snoyes

Ah... no, I have an 06 and could correct my tire size for 35s with both the Bully Dog and the Smarty. No limit on size...

May be true for the 07....

So is there an answer to my question? What is the tallest and skinniest tire I can put onto my stock 17 inch rims?

Did you have to use spacers between the rear tires to keep them from touching? I've been looking at the LT285/75/17 E (34") Nitto Durra Grapplers.
