My apologies in advance, new to forum and have a basic question. I just moved up from a ‘17 F350 SRW to a ‘20 F450 DRW for pulling our 20,000 lbs 5th wheel. Super stoked! Question: I need to get new tires and would like to fill out the wheel wells a bit more, but I want to save a little money and not change 19.5” rims. Are there any clearance or performance issues increasing from the 225/70 to 245/70? If there are no issues, what is the best tire for long hauls over mostly dry and wet roads with occasional snow covered roads. I am quite confident this topic has been covered before and several of you have great recommendations.
Be aware that 19.5 tire manufacturers do not recomend wider than 225s on the factory 6" rims.
I pesonally went to 245 Toyo 608z.
It is difficult to get a flat tread contact with too wide of 19.5 tires.
Not saying you can't or shouldnt , just be aware of the recomendations.

Can see it in this picture where the edges are untouched.
Kind of looks like the stock front tires on mine with 44K on them, worn on the edges with a hump in the middle.
They look like they have pretty good traction, how are they in snow? No matter what I look at, tires for the 450 are expensive, might as well get the best ones you can.
No the edges are not touching yet. The tires only have 1500 miles on them. running 75 psi in the rears and 80 psi in the fronts. The fronts are the same way. I would assume that after 5-10K they will flatten out a bit.
If you're looking for snow traction this is what you want. MICHELIN® XDS®2 19.5 | MICHELIN TRUCK TIRES (michelinman.com) Only available in 225 and 245 size though. Which won't bulge as bad on a factory rim. Keep in mind as you go up in width and aggressiveness the speed ratings often go down. Tires on the truck shown are 225s.
I recently got a set of Goodyear G622 225/70R19.5 to replace the stock continentals. My primary usage is hauling my 16K toy hauler long distances at reasonable speed as well as pulling it down sketchy dirt/sand roads and through snow when I have to. I don't pay too much attention to how close together the rears are nor how they make the truck's wheel wells look since function (and price) is all I really care about.
The G622's are rated for 87 mph, and I found they will pull my toy hauler through 6"-8" of sand and about the same of snow just fine. I use 4wd & "deep snow/sand" mode for those conditions. I don't vary the pressure between loaded and empty or based on surface - 85 psi front, 75 psi rears seems to work in all conditions for me.
My only complaint is that, when empty, I can't pitch the rear around in the snow much as I could with the Contis because they grip too well.

Thats a complaint! LOL
I am curious how the fronts are wearing since the F-450 has such a sharp turning radius, it likes to eat traction tires on the front. I am considering Roadmasters for when mine are due, the Contis have 44K on them, the rears are flat with plenty of tread, but the fronts are bulged
in the middle due to edge scuffing. The GY tires look like a good option for the rear.

True. I only have about 4000 miles on them, but so far I don't see any unusual wear. I had the same concern about "drive" tires being used as "steer" but I wanted front traction for sand & snow. I use my F450 as a daily driver, so I do use all of the turning radius it has almost on a daily basis.
If this thread is still alive in a couple months, I'll post an update.
2022 13,913 miles... If warranty works I'll wait but I've been keeping an eye on the forums trying to decide steer tires on the front or something else. I don't offroad just daily and tow a momentum a lot in the summer. Planning to take the truck to Colorado February and probably yearly so maybe steer tires and chains for the front idk. The rear are immaculate, I don't plan on touching them for awhile. Just want something that is going to last and perform well for my use.
What the heck are you doing to your front tires? Are deer having snack time on them? Those should be warranted, chunks dont just come off like that in normal driving.
On that drifting a dually, you know, one wheel hop can become very expensive. I know, Been there, Done that! Blew the spider gears out the back cover doing a burnout. Required a full rebuild of the differentials.
.. I live near some nice flat open parking lots that get covered with snow from time to time. Ken Block (RIP) inspired me with this ..
