Ford, GM and Chrysler cash in on posh pickups

difference in rim weight is much more than any difference in tire weight Think about it... You've just replaced a little bit of sidewall rubber with much heavier metal rim. It's not rocket science...

You simply cannot compare just rim weight. Remember that tire weight will have a bigger affect on braking than the rim because weight applied to closer the outside diameter has more affect on the rotating mass.

Larger rims DO takeaway from braking power and also take a fuel mileage hit simply because they are heavier than say a smaller 17" rim. Even if tire diameter remains unchanged your rotating mass has increased.

I choose to run 20s simply because I like the looks of them even though I know a smaller rim would perform better in most cases.

Since 2005, Ford had been using 17" rims due to the size of the brakes. The larger rims do not take away from braking if overall wheel diameter has not changed (reduced tire sidewall), however reducing too much of the sidewall does reduce payload capacity.

Once you go up to 19.5" rimmed trucks, the brakes are larger. However, they do have other ways to make braking more effective and apply this to the DRW F350.

Been going on for years... Why is this "news"???

Yes, luxo trucks have been around. But it it a recent development that the luxo-trucks are now making up such a substantial proportion of overall profits.

So the last 15 years is recent?

When Ford built my '98 F150 Lariat they had two facilities working 6 days a week, 3 shifts a day with mandatory OT just to keep up.

It's been going on a while.

None of the pickup makers install larger rotors when you order 20" wheels. Taller tires reduces braking power. Simple psychics.

17" wheels fit over the brakes of all 3 of the 1-ton trucks. That is the only wheel size wheel even available for the heaviest GVWRs, with exception of the 2015 F450.

All the more potential failure points, IMHO

Agree in so many ways. 20" rims, = reduced towing capacity, or they do according to the manual.
And yes there a re lots of power stealing electronics that tend to quit working. While the new engines will live much longer than ever before. So many other things in the truck won't. Like the electric windows, that do not like the harsher ride of a truck at work,($250.00 each several years ago) and then there is the electronic dash. Nothing mechanical there. Want to know how much it cost to replace an instrument cluster. $700. several years ago, and you know it is way more now. Then the electric seats, and heated seats, electric rear window, power pedals, memory seats, electric mirrors.

Every one of those options do at least 3 things. First they ALL take towing, and payload capacity from the truck. Second, they add thousands to the price of truck. And third. They add thousands to the upkeep of the truck.

Honestly. sometimes I am afraid to start my truck, for fear of what won't come on. So far everything, except for a few door lights do, but after 11 years. the engine is great, but other things are beginning to show their age. My next truck will not be a Lariat. But an XLT, with as few electronic gismos as possible.

Fish...Dirty is on my blocked list for a reason and your quote of his
comment verification to me why. Do not ever see his posts...unless
someone quotes them like you did. He and his kind is waste of my time
and ask that Dirty likewise block me so he won't have to put with me

Dirty is a novice techie from his positioning/comments and he is a
Proverbs26,4 kind of person to me

Yes, larger dia has a longer moment, but there is more to it than
that one aspect

Using Dirty's analogy...my puny disc cann't stop anything compared
to the new stuff...well I can initiate ABS at will in most conditions

I've braked to feather this Michelin LTS-MS LT265/75R16E
pictured...it got way worse before it started to crack to no longer hold PSI.

feather feathered

Can you guys?

Why not?

Hint...it has to do with modulation and that braking force curve
Hint2...ABS won't allow you guys with OEM brakes to do so

Oh well, Dirty didn't impress me when I blocked him and continues to
to not do so...'Modern' is all he knows, or so he says in Fish's quote
of him

Maybe he also thinks his 'modern' ratings requires more TV braking,
but isn't he also one of those who say no need for the TV to do
the trailer braking...because the trailer has brakes and no matter for
the TV, right?

Fish, you are correct that the larger dia wheels do allow for larger
dia disc's...you two know why one reason larger is better, generally?

Hint, told you so up above...

Yes in your time dated humble opinion... 18/20" rims required now a days due to the larger brakes found on "modern" vehicles... unlike your 96 burb with its itsy bitsy 16" wheels or your 80 chevy 1/2 ton with its even smaller 15" rims...with larger tow/hual caps with the "modern" vehicles, larger brakes are required to stop em.... your itsy bitsy teeny weeny brakes from yester-year wouldn't... couldn't stop today's "modern" vehicles! Hardly a "fashion statement"!

As for cost of replacement parts... all relative...betcha in 1980 that driver side mirror was a heck of an expense at that time as it is now. Love how some continue to try and get us to swallow the old ... "had to walk 10 miles up hill both ways to school every day... and in a blinding snowstorm at -55 degrees..." :B

Agreed... The larger diameter wheels accommodate large diameter Rotors.

Agreed:
