Thank youTruck looks great! I never thought I’d be into bronze wheels til I saw them on my truck. Love’m and welcome!
I have a similar '19 Lariat, though just bought recently, and have the 18" aluminum/mag wheels also. Those reduce the cargo capacity? As an 'upgrade', they are heavier than the non-upgraded stock wheels that much? I'm not too concerned if they do, but I was also thinking of wheels with a little offset or perhaps small spacers. How much bigger are your tires than the stock ones, didn't your offset wheels help reduce the tire rub or did they make it more of an issue? You're still running 265's on 17's instead of 18's it appears. Thanks!
The load rating of the 265/60-18 Dynapros limit the cargo capacity of the Ranger. Drivers door jamb sticker lists 1356 lbs with 265/60-18 tires. I was surprised they rubbed when most members had no rubbing with 265/70-17 even with +20mm offset wheels. My Ranger was built January 2019, first month of production. It is possible mine rubbed due to manufacturing tolerance fluctuations. My tires are 31.6” tall vs 30.4” Dynapros. The KMC Trek wheels poke out 1-3/8” farther each side than factory. There are not many aftermarket wheels for the Ranger that have positive offset close to the factory +55mm. I wanted a more aggressive stance without the roller skate look. These have 20mm so I believe they may have contributed to the rubbing. I am very happy with them. They do throw more mud against the side of the truck.
ThanksNice Ranger!!!
OK thanks, yea I do like the look. So your KMC's + 20mm (around 3/4") netted out to 1-3/8" additional on each corner? I was assuming you'd have to go larger offset to get that result. I also thought about the mud and road grime, just added mud flaps which are good for stock at least. I also had heard that these ongoing trans issues can be aggravated by lifts and spacers/offsets but not sure especially on levels only or small lifts. Had you heard anything like that?
Factory Ranger Wheels are all +55mm (Raptor +44mm) offset. The KMC are +20mm so 55-20=35 / 25.4mm/inch = 1-3/8” difference or additional “poke” outboard. The 55mm offset wheels “suck” towards the inboard of the vehicle. Any offset less than 55 push the center of the width of the wheel outboard. 55mm offset wheel “spokes” stick out towards the tire sidewall and can hit rocks easier than wheels with less positive offset. Ask me how I know this.
The 1-3/8” poke outboard apply to 8” wide wheels. If you buy 9” wide wheels (1” wider) they will poke outboard an additional 1/2”.
Check out tiresize.com for a realistic view off different offsets and tires sizes on your vehicle. It clears up things considerably.
It does help, thank you, I appreciate the convo's with people who know. Good point, forgot that the offset is (-) to increase so reducing from 55 to 35 brings the wheel out so to speak. That then makes sense that you'd get that difference by reducing it. I haven't yet been off-road in this '19 Lariat, just got it, had a Colorado ZR2 prior that was great off-road and got crushed by some tech bros screaming down the highway. I haven't experienced the spoke rock issue yet. Appreciate the space perspective also - I've seen people use and many take them off, wheel/offset seems the better approach. I'm a little concerned about the trans as many in the ZR2 groups had it, GM and Ford did this together. Also makes me wonder why people paid extra for the 18" aluminum wheels when they reduce your load capacity and also it seems like fewer good M+S tire options in that size.
(55mm) -(20mm) = +35 mm offset difference = 1-3/8". I switched to the 17" because there are more options than 18". 265/70-17 gives you more sidewall height (70 series) relative to the width. Imagine being in the SE Oregon bad lands and have tire issues. Limp to the nearest town and try to get a replacement tire for your 18" wheel. Not going to happen out there. I did a 3 day, 150 mile off road trip on the Mojave Road (in CA) with two Tacomas and my truck had the stock suspension and factory 18" Dynapros. My truck did everything the Tacos did and got 20 mpg compared to their 12-14 mpg. The 10 speed and 3.73 axles is a great combo for rock climbing. It just went over everything without breaking a sweat. We all lowered our tire pressures to around 22-25 psi on the trip and had no issues. My Ford dealer in CA did not want to do the transmission software up date until I demanded they do it and provided the TSB # and they complied. They acted as if there was no such TSB.
Yea the ZR2 was a beast too, those multimagic shocks also made road driving really smooth. My original stock Duratracs lasted 85k miles, shocking but a lot of highway miles and always rotate. I haven’t seen any TSB notices since I got this and registered it with Ford online, but haven’t been to a Ford dealer yet. Can you search those via FordPass or your Ford account for your specific vehicle? Hope so, I guess they don’t tell you unless you have an issue of course
I found out about the TSB from this forum. There used to be a whole section on drivability issues and the fixes. Have not looked for it in a couple years. Not sure if I can read the transmission software version with my ProCal programmer that came with my tune. My transmission software was updated under warranty. Out of warranty, you will have to pay a dealership for the work. Not sure if the update is available to independent auto repair shops. Ford may consider it proprietary. I used my ProCal programmer to change the revolutions per mile of my new tires in the computer so the speedometer would be correct. I checked it against a GPS speed app on my phone and now it is displays the exact speed. No more error. Hope that helps.
