17s on a 2019?

Will 17s clear the brakes on a 2019? Weighing wheel options, and I am considering some 17s. I know 18s are a factory option, and they haven't done 17s in a few years, that's why I am asking.

17" tires are under rated for these trucks and lack a broad choice of weights\sizes as 18's or 20's. 17's are now gasser only rims.

Yes they will fit. 3500 DRW comes with 17 wheels from the factory.

Might want to double check that......
Looks like the truck below is a 2019 and a diesel and has LT245/70R17 tires.

You might double check that a little deeper., That truck is only rated at 6k on the rear axle, just like all the gassers. NOT 6.5k rear axle like all CC and QC trucks which the OP has.

Per DOT 17" tires have a max rating of 3195 lbs per tire, not adequate for a HD diesel application. The Tradesman 2500 Reg Cab is a gasser platform with a diesel, a bastardization to cater to a market niche.

17's only come on the DRW's because they have 4 tires to meet the ratings, essentially gasser platform for anything less than a 3500 DRW platform. Really, a 245\70 tire is doughnut, on a diesel it is inadequate for the engine weight. While they might fit the OP's truck, not a good application choice.

Your tire load data isn’t completely correct. It may be for the factory size but some of the larger tires are in excess of that number. FWIW. Procomp AT in 37x12.5/17 is rated to 3525 as one example.

That said, the OPs question is will they fit. The answer is yes.

I wasn’t the one that said “17’s are now gasser only rims”........you were.

I disproved you, and you go straight into argumentative mode. The front axle is rated at 5,750 lbs and the rear axle is rated at 6,000 lbs for a grand total of 11,750 lbs; the truck has a 10,000 lb GVWR.

The Firestone Transforce HT tires in LT245/70R17’s in this exact case are rated at 3,000 lbs each......3,000 * 4 = 12,000 lbs, again, more than enough to exceed the combined GAWR of 11,750 lbs and the GVWR of 10,000 lbs.

It’s really refreshing to hear you toot your horn and know more than the engineers at RAM as well as know more than the legal department at RAM regarding FAWR, RAWR, GVWR, etc.

The axle ratings are somewhat arbitrary in nature as the axle rating is ultimately determined by the tire and wheel package that are under it. I’ll bet a frog’s phatttt assssssss that the regular cab truck I linked to has the same 11.50” AAM under it that a 2500 regular cab, 2500 Crew Cab short bed, 2500 Crew Cab long bed, or 2500 Mega Cab has.

And....the last I checked, RAM dual rear wheel trucks have six tires and wheels total, not four.

'19 tradesman 2500 srw came w/17's stock, so yes they will fit. how someone is arguing with what came on a truck from the factory is beyond understanding.

Nobody is arguing that. However, someone is claiming he knows better than Dodge when it comes to rating truck configurations, tires sizes and such. They must be so because he saw a web page and everyone knows if it is one the internet it has to be true.

These are the stock 18” steelies off my 2019 gas Tradesman. That gap between the rim and caliper is approximately 3/8”... an aftermarket 17” MIGHT fit... clearance will vary....

Here’s some questions: Does your diesel have bigger brakes? Does the base 2500 in which 17” rims come stock have smaller calipers or specific rims design with clearance?

These are questions you need to be asking your tire/rim dealer.

All of my information is based on facts.

Lots of your information is based solely on opinions.

When one tries to pass off opinion as fact, like you did in the above post, all it does is confuse the readership.

The only web pages I visited were...
  • The Tire Rack, to source information about the Firestone Transforce HT tires
  • Kernersville Dodge, in order to source the door decal for the information I originally posted
  • No “opinion”.......just strictly facts

Your attempt to spin things, when proven wrong, is actually quite entertaining.
