@Carlos.33193 What fender flares are you running? My 20 limited is getting lifted on the 15th this month going down to 20's on 35X12.5 Nitto gridge grapplers. Great looking truck man

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.

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….

Thanks man. Can’t wait to see pics of yours.
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.Yes it’s calibrated. I wish I could lend you the module… it’s one time use and was $300..

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.
Love your wheels. Can you tell me what model they are?
