I bought a set of direct bolt on 19.5;s for my dually. They are classic style, 8 hole alcoa's with a set of michelin 285/70 19.5's

Has anyone tried this setup on a f350 dually 4wd dually?

Have you installed them yet? How are they working out for you? What is the difference in the ride, handling, and braking?

Tell us more and show us some pics.

I think the 19.5s look great on a dually. I'm not a fan of the 22.5s, they look out of proportion to me.

They have not arrived yet. Fed Ex Freight picked them up from Orlando this morning, and I expect arrival in a few days.

I will post pics as soon as I get them on the truck. I was able to buy them from a friend I met on a boating website. 6 michelin xde x265/70/19.5's, 4 alum alcoa classic 8 hole wheels, two steel inners.

2800.00 plus shipping. I think shipping will be around 400.00

I can't wait for them to arrive. I just got the truck back from the dealership. Head gaskets changed, ARP studs installed, heads were sent to machine shop to check for cracks/warps. All was good, only gasket blowby due to bolt stretching.

I will be re installing the edge programmer and a gps to monitor speed. I think the 19.5's will throw off the speedo. I will report on how much.

Here are the pics of the setup from the previous owner

Those are some great looking wheels and tires! Make sure you post pic's and a report of how they are working for you on the truck as soon as you have them installed.....

6 michelin xde x265/70/19.5's,

I can't find that exact tire on the Michelin website, so I suspect they don't make it now. But I found the XZE-2, which comes in that size.
Michelin Americas Truck Tires XZE®2

I will be re installing the edge programmer and a gps to monitor speed. I think the 19.5's will throw off the speedo. I will report on how much.

LT265/70R19.5 are very close to 35" tires.

The speedo will be off the percentage of change in tire revs/mile. Your stock LT245/75R17E tires have 664 revs/mile. Per the specs at that link above, the XZE-2 LT265/70R19.5G have 607. 664 minus 607 = 57, divided by 664 = 8.58%. So if your speedo is accurate now, it should be slow by 8.58% with the new tires. 70 MPH per your speedo will be 76 MPH per Officer Bob's radar gun (and a good GPS).

However, any decent Ford tech can correct (calibrate) the speedo. Most dealers will charge you about one hour labor rate for an experienced tech to do the 5-minute job of calibrating the speedo.

Or you can spend about $200 (street price) and DIY with your own calibrator.

One disadvantage of those taller tires is your final drive ratio will feel like longer legs. Your 4.10 axle ratio will reduce by that same 8.58%, so when hauling or towing heavy your truck will feel like it has a 3.66 rear axle ratio. You can get most of that power and torque back by changing the ring gear and pinion to a 4.30 ratio. Then your truck will feel like it has a 3.93 ratio. Or you can change it to 4.56 which will feel like a 4.17.

I run 245 Michelin XDE MS 19.5s on Rickson Wheels on my 99 DRW. They have been great tires and I will easily get 100k miles out of them, even with a fair amount of heavy towing and mostly higher speed highway driving.

I really wish I wasn't so cheap to keep from putting the larger wheels on my truck. They look fantastic. I just can't justify, especially to the wife, spending almost a third of the truck's current value on new wheels & tires when the current ones are doing the job just fine

Have you put them on yet? Any pics?

RNMack,
Do you know who the original retailer was for you wheels and the cost of the wheels when new?
Thanks

 

[SIC-E]

are the tires in the pic, 285's per your OP or 265's as mentioned later in the post just prior to the pic?
man i want to get to the point, in my build, of getting wheels. those are mandatory! gonna hate to spend on two gear swaps, but....
nice! nice ricksons as well! have tallked to them a few times too. web site is helpful.

It's been a while since I posted. I have approx 60k miles on the tires, and have rotated twice. The fronts wear quicker and uneven. I have the two inners left to rotate to the front. They still look even. I have to go to a big rig tire shop for mount/dismount/rotate and balance. Cost is approx 200.00.

The wheels are Brentz brand, and are hard to keep shiny. I work construction, and one pass in mud dulls the alum. Hard to polish without removing from the truck.
Positive is that they are very stout. While pulling my 38' formula fastech boat with 46'trailer, the truck rides better than with the factory tires. It holds steady, no bouncing up and down.

The tires are very slick on wet surfaces. My truck is back to stock engine and I have to be careful on wet roads. A little too much gas will turn her sideways.
If I buy a 2011, i will pull them off before trade in. Probably put on a crew truck.

Skip the balance part and put Dyna Beads in them, use which ever brand you like they do work. I have Hankook 19.5's on mine they have never needed to be balanced, just the Dyna Beads. I rotate them at every oil change. The more often you put those front ones on the back the better they will wear. $200 to rotate them for less than a 30 minute job even without a lift that's expensive. I have 40K on mine and should get at least 100K.

I bought a Dewalt polisher and a couple of small wheels for my my die grinder this spring that certainly takes the work out of poilshing them.
