I need a favor from someone with a truck.

Could you please dangle a sting with a weight or stick a tape measure from the top of the fender down, and then measure with a ruler or something (in mm) how much space there is between it and the outer edge of the tire both front and back?

I'm trying to figure out how much the wheels/tires tuck into the fender on flat ground without load.

Thanks.

I was actually wanting to know the exact same thing! Wanna make sure if I get bigger tires that they still travel properly inside the wheel well without hurting the truck.

Should have my truck in a couple of weeks and I will capture some measurements if nobody else does before me.

The rear is 9”/228.6mm
The front is 6”/152.4mm

Hey bud. I think you misunderstood me, I need the measurement between the outer sidewall of the tire and the outer edge of the fender just to know how much the wheels/tires tuck in, it should only be a few mm. Thanks.

Thank you. (y) 🙏

Interesting that they tuck more in the back.

It is interesting but I noticed a couple months back this very issue. When I would look at these trucks from many angles I would wonder, why are the tire tucked in more in the back? So then I’m thinking should I get aftermarket wheels with different BS for the front and the back. Then my brain went 💥

Probably has something to do with the fact they moved the front axle forward and most likely outward some if they didn't move the frame rails in some.

Or the rear fender bodywork just flares out slightly more than the front relative to the frame.

It's a bit of an issue though because if one wants symmetry then they're gonna need to do staggered offsets, which is a little tricky on an AWD. AWD vehicles normally have a programmed percentage threshold past stock that you can't go past in regards to staggering wheel sizes or offsets or it will throw a CEL. Sometimes all it takes is a few mm. But I don't know the AWD mechanism in this truck to know how it measures that. Do these trucks have an AWD system with a transaxle diff or some other AWD mechanism?

We'd have to either trial and error this one out or talk to an Ram engineer (calling @KnightMare) to know for sure. Otherwise we're going to have to pick an offset for front and rear the best balances out the look of the truck. As in does one want to be flush at the back and stick out 6mm in the front, or some other combo.

Just to add, 6mm is essentially 1/4" which isn't a small thing (giggity). I've seen German AWD cars throw a cell because someone put a new set of tires in the rear and not the front and just the tiny bit of rotation difference between the two made the ECU throw a fit. I know that staggering isn't the same as rotational but it is normally part of the coded parameters as it affects rotation when cornering.

Maybe I'll buy a pair of 1" and a pair of 3/4" spacers and see what happens.

That is interesting. I was tryin got process the idea of just moving the rear wheels out6mm and how that would effect the ECU program. I’m starting to come around but still a bit Skeptical.

So let me ask this then, if we were to mount all 4 wheels out 6mm would that have any impact of the ECU? Because, I would be happy with flush mounted rears and Bulging fronts.

That's not an issue at all, if you do equal offsets it won't negatively affect the ECU.

I love it when you guys speak Chinese..... however I do find it interesting to learn about all the different aspects of the mods.. I’m just a complete noob to most of it ... obviously... Cheers
