quick question the father inlaw has a 2010 QC LB dually and the tires look like crap for winter anyway. i saw a set of winters for sale for cheap there rating is 2200 lbs a tire is that enough? he would not be pulling his 5th wheel in winter so no real heavy towing would be in store. they seem a little low for a srw but for a dually it seems they should be fine thoughts? i cant find the rating of stock rubber

 

That sounds like less than a C rating for the standard size. My Cooper discoverer st 265/70/17's are rated at 3195Lbs. A comparable Cooper in the stock size is 3085lbs. Add them all up (2200x6= 13,200) if the truck won't be around that much during the winter those would probably be fine. I run my coopers all year. I feel on a dually you should run at least a D all year. If you happen to forget the load rating and hook to a trailer, who knows what could happen. Just my .02

 

Just my opinion but you need an E rated tire not only for the weight rating but for the sidewall strength too. The lower the rating the more sidewall flex and sometimes that can really mess with the control of a truck that weighs 4 tons.

 

Never underate the load rating of tires.

Its not only load capacity but casing integrity and Side wall stiffness.

I'd be willing to bet those are p-rated tires. Those have no business on a 1 ton. In fact they have no business on any diesel truck.

Don't be a cheapskate. Seriously, if you want winter tires for a truck buy winter tires for a truck.

There are now tons of tire options for the Dodge dually 2003 & newer in the stock tire size & load range E. (LT235/80R17E)

While I don't drive my truck much in the winter anymore, I run LT235/R8017E Cooper ST's on steel wheels on my SRW 2wd for the winter.
They work totally fine as long as I leave my 5th wheel hitch in the back for weight.

 

2200 lbs/tire is not sufficient on the front. The back, unloaded, would be well within the ratings, but still not a good idea.

I run Bridgestone Blizzacks on mine in the winter time. They are a very good tire. Especially with some weight in the back. Call some shops, should be able to find something comparable in 235/80R17's. Getting a set of dedicated winter tires makes that whole season much more bearable.

 

I run Cooper ATs all year round and have been very happy with the winter traction.

The only time they let me down was when I went somewhere I no business being with a dually and a 15K trailer. I was a bit surprised how easily they plugged up with mud though!

 

The front on my 04 is 4800 lbs... That was before my buck stop bumper and winch... 2200 a tire is waiting for a major let down..

 

Did you miss the word 'not' in that quote, perchance?
