So I'm looking on upgrading my "33 inch" procomp M/Ts in for some 35's. It has come to my attention that just about every brand of tire doesn't measure up to its claimed size...go figure. (My 33's are actually 31.5's). That being said and understood, I want some actual 35's on my 2 door. Should I just get "37's" and assume they'll actually only measure 35 inches or will a tire measuring a whole 35 inches not fit under a 3.5" lift? Any tires out there that are remotely close without airing them up to unsafe/useless pressures? Any pics or suggestions?

 

I'm pretty sure MTR/Kevlars run true to size.

 

I here ya. Got mtz"s 33 and where the same as the 31 wrangler"s Kind of pissed. What did I pay for. Great tire but if I would of known I would have gotten 35's. So I am looking at tires and am now thinking of 37's just in case they don't measure up.

 

Eventually they will Sticky this question and have the following:

"Brand / Model"
"Wheel Size"
"Claimed Tire Size"
"Actual Tire Size (@ "x" psi)"

Mods?

 

I have 37" mtr's and they measure at 36.5 on the jeep @ 30 psi, I have heard that the 35's are very similar and that they come in at about 34.5. But hopefully someone with them will chime in to confirm.

 

35 12.5 15 Kevlars measure from the ground to the top of the tire 34.25...................

 

I just put 37" Cooper STT's gonna go measure now to see if they are really 37's...by the way they fit under a 4" lift...they measure 36.5" at 36 lbs...

 

I run the 35 MTR-K on 17x9 rims and they measure in at exactly 34.5. Other things to consider in tire height is rim diameter and rim width. Both will effect the overall height of the tire.

 

if we are running our tires at a lower psi then the factory states on them, doesnt that take away from the actual height? just a thought, but i see some guys running them @ 30 psi on 35's & 37's. what is the psi called for on the sides? i run 33's and at 30 psi and havent measured out to see where mine sit at.

 

I would imagine the tire manufacture's measurements refer to the tire unmounted, maybe even just to the size of the mold the tire is pressed in. They have no way to know what psi they will be ran at, what the intended vehicle weighs or what width wheel they will be mounted on. All of that affects the finished "height". I think for a more even comparision when the tire is mounted and on the vehicle, measurements should be made across the tire horizontally, parallel with the ground. (not vertically from the ground to the top). This should minimize the effects of varying air pressure and weight.
