I found a setup on custom offsets that showed 37's with 3.5" ReadyLift. 20x9 +1 using a 11.5" tire. I've tried finding the actual person to discuss this but can't find them. Anyone in here ever tried to squeeze a 37 under a 3.5" lift? I don't want a 12.5 or 13.5 tire.

Nice! Thanks man. Is your speedometer calibrated? Mines not calibrated
That makes sense because I'm at ~1950 rpm at 75 mph with 33's with a calibrated speedometer. Your speedometer is off by about 10 mph at 70-80 mph.

Yes it’s calibrated. I wish I could lend you the module… it’s one time use and was $300..
maybe I’ll use it on my new TRX one day….

You can spend $100 for AlfaOBD and use it as many times as you want.

Ahh gotcha! I haven’t calibrated just because I don’t really mind my speedo being off because I just go with the flow of traffic usually lol. But it would be nice to see my correct mpg! I have to hand calculate everything.

Hand calculations won't work either because your odometer is off too.

Yep I know the odometer is off. The odometer, speed, and mpg is off. But I know my tires are 14% larger than stock (I’ve calculated and tested it) so I know my odometer, speedometer, and mpg are off 14%. So at 66mph on the truck I’m actually traveling at 75mph. Every 100 miles I actually travel 114 miles. And if the truck says 11.6mpg avg then it’s actually 13.3mpg (according to the truck itself - but surprisingly my hand calculated numbers are usually really close too). I find my true mpg by taking how many miles the truck says I drive (usually about 280 miles per tank), multiply that by 1.14 = 319 miles. Divide 319 miles by how many gallons it takes to fill up. Usually 24 gallons to drive 319 miles, so I average 13.3mpg.

Yep, you've got it figured out. I was just discussing this with another member and while he was aware of the speedometer error, the odometer error slipped his mind.
