Overland with Rubicon rims/tyres A/T:

I was being safe & aware, no worries fellas.

Interesting, I’m running rubi wheels and tires as well and have 3.73 in my sport and my rpm is around 2k to 2100k at 75mph.

with stock wheels/tires my GPS showed I was actually running 2mph slower at 75 then my speedo showed... after getting the rubi’s it’s now dead on according to my gps... go figure

spacer lift and 37's. For an entire tank of fuel: 13 to 14 in town when I drive normal, 14 to 15 when I'm trying very hard not to smash the gas pedal.

Stock Rubicon. If I drive the speed limit I get 20mpg. I have a round trip 124 mile commute.

Sport S. Completely stock engine, tires and 6 speed trans

 

[Jt-wrx]

458 km's to 70.4 liters = 15.37 l/100km or 15.3 u.s. mpg. (l/100 and u.s. mpg match each other pretty close in the 15's lol)

Sport s 6-speed, mopar lift on 35's, gps speedo corrected, hand calculated, 90% city, winter conditions, winter gas, ess disabled, magnaflow street series exhaust only engine mod, over 3000 kms on engine now.

This is about as bad as it will get for me, i can live with that.

Ha! My sport s came with factory tire height setting at 32.24" when actual height was 31" measured...so as i suspected they put Rubicon tire height setting as standard to all of them. So most mileages from overlands/sports will be inaccurate. Just sayin...

LOL How are you measuring?
Rubicon tire diameter is 32.8 for the Falken A/T according to the Falken site.
So why are you suggesting Jeep is putting in the Rubicon tire "height" on all of the JTs?
32.24 isn't even a Rubicon tire "height".

You don't measure "tire height" with it on the truck. It's tire diameter, not "height" installed.

Go to the tire manufacturer's sites for the facts, not what people say they are here.
Diameter is what counts because diameter determines ROTATIONS PER MILE TRAVELED. (well, circumference actually does, but you get circumference by the diameter)

Diam/height same thing lol. What the manufacturer lists is always taller than actual measures diam/height. Ie; most 37’s run actual 36. Most 35’s run low to mid 34’s. My stock sport 245 74r17 supposed to be 31.5”...the ran 31” on the nose. Like to tell you o had some 33’s to compare but I didn’t. Lots of threads out there on Jeep and other 4x4 forums about actual heights/diam. So you’ll see, any tires listed number is inflated. So 32.24” wasn’t a number I made up...that’s the number Jeep already had input into my stock sport s. I know this because I bought a tazer jl mini and plugged it in so I could change whatever the factory setting was. It was 32.24”...which sounds about perfect for an actual 33” don’t you agree? The setting I had to input for my 35’s to get bang on at 80 mph was 34.44. My tape measure showed me just a little less than that but I was eyeballing, could have used a board and a level but since I could just go for a drive and use gps speed and just stop and adjust incrementally to be perfect that’s how I did it. My hypothesis runs true as the guy who put some 33’s on his sport the speedo ended up bang on at 75 mph when with the stock sport tires he ran 2 mph slower. He has no idea what his factory setting is...I do lol. It’s 32.24 set for 33” tires. We good?

Jeep is likely programming all of them for rubicon spec as it’s probably the volume seller anyway...more will be right than wrong and the others close enough few will notice so why wouldn’t Jeep do it that way? There’s two sports now to verify that. Annoying eh? I agree.
