What size measures closest to 35?

cmireles · Sep 30, 2014

If I were to want, say, a 35 inch trail grappler, and want it to be a true 35 (or as close as possible to) inches, would this be the 315/70/17? Or how does this work?

315 will measure bigger then a 35, yes.

35.0X12.5R17 = 318/72R17

Probably not a available size but that is the metric conversion.

Lots for conversion calculators on the net. https://www.google.com/#q=tire+size+conversion

assuming you mean you want it to measure 35" after being mounted on a rim and on your jeep? If so, you might want to look for a 36" or 37". very few 35's will be 35" after mounted. i have 315's that are 34.5" on a stock rim (narrow rim means it will stand taller but not be as wide)

true but I asked because I am aware that the 35x12.5 actually measures closer to 33ish inches. 315 looks to be the best option?

yes 315's will be your best option when looking to stay closest to a true 35. when i had my 315/75r16's they measured around 34.25 when mounted and at 28 psi.

I'm not a metric guru but just 315 might not yield you what you seek. the second number in metric also effects the height.

Just a pasted blurb:

Typically following the three digits identifying the tire's Section Width in millimeters is a two-digit number that identifies the tire's profile or aspect ratio.

P225/50R16

The 50 indicates that this tire size's sidewall height (from rim to tread) is 50% of its section width. The measurement is the tire's section height, and also referred to as the tire's series, profile or aspect ratio. The higher the number, the taller the sidewall; the lower the number, the lower the sidewall. We know that this tire size's section width is 225mm and that its section height is 50% of 225mm. By converting the 225mm to inches (225 / 25.4 = 8.86") and multiplying it by 50% (.50) we confirm that this tire size results in a tire section height of 4.43". If this tire were a P225/70R16 size, our calculation would confirm that the size would result in a section height of 6.20", approximately a 1.8-inch taller sidewall.

My plan is to run on a 17x9 with 3.5bs with cut fenders and no lift. Would anyone recommend the 37x12.5 in this situation?

go play here to be sure http://www.americastire.com/dtcs/infoTireMath.do?dbar=true&r=CAOINT|pc|92692&

Wonder why we never converted to the metric system :doh:

pvanweelden · Sep 30, 2014

^ no, but 315/70 r17 will do just fine at stock height and trimmed fenders- add a 1.5" bumpstop to the rear, and throw a spacer in the front if you need a little extra height after a bumper/winch.

Sounds great, thanks for the info!

Okay will do, thanks for the help.

My 37" trail grapplers measure 36" even at 26psi on a 9" wide wheel.

Yeah I think I'll just stick with the 315s then lol

Damn Branman, that made my head hurt and I'm in Australia and we mainly use the metric system for tyres or tires as you guys call em :cheesy:

My 315's also measure 34.5" :driving:

Not neccesarily true. Depends on brand.
