Tires

Post by Mr Big Wrench » Sat Oct 08, 2005 7:39 pm

I have a "STOCK" 04 2500HD 4X4.
How large of tire will fit under My rig without a lift kit?
I can crank up the front torsion bars if needed, but I don't really want a lift kit, especially a 6" one like most of the companies have.
Thanks in advance.

I think 285's would be it without trimming the bumper.

Nothing wrong with a 6" lift kit and maybe some 36" tires, but The Wife can't get in an out of Our Stocker, no less one thats lifted.

I also tow a tag TH and don't need to modify stuff there either.
Thanks for the info on the tire size.

Cranking the torsion bars won't give you additional clearance at the front edge of your fender (bumper really), which is where you'll need it for bigger tires. Sorry, but the only way you'll get to anything bigger is by going up.

On that note, I'm looking into a set of electric powered running boards. These are the kind that tuck up aganst the underside of the rocker panel when the door is shut, and automatically drop down to a usable height when you open the door. Very clean, and when you paint the underside to match the color of your truck, you can hardly tell they're there when in the "up" position. Only downside is the cost. $2500 for the set! OUCH. But, I rode with a friend that has them on his '05 2500 w/ 6" lift and 37" tires and they were really nice.

I had an 03 2500HD 4x4 and put 285/75 on the stock 16" wheels. I used the torsions to level the truck and had to trim the plastic on the front bumper (very little, and not even noticeable to anyone but a GM owner).

Thanks for first hand experience. I'm running 265's and they clear, figured 285's would be right at the edge. Did you just have to trim the lip inside a bit?

FYI I went to costco because they had the best deal and they have a policy of not mounting any tire larger than what's listed on the tag on your door, which would be factory size 245 in most cases. Had to go to america's tire store and they were pretty close on price anyway.

Here's mine with just a torsion adjustment. Don't remember what tires the wife put on but I think they're 33's. I'll look tonite. The problem with torsion is that you gain a ton of 'bouncy' when going over anything larger than an acorn. (Or the squirrel :shock: )

Ya you really shouldn't crank the torsion bars much at all. You lose the down travel for one and the bounce can be dangerous when your coming to a stop on a rough corner or anything like that. Bet you know exactly what I'm talking about with the abs brakes kickin on at the wrong time don't ya Rekd? :shock: :( Not good at all.

Thanks again for the info.
I was planning on trimming the plastic and maybe leveling the truck with the T-Bars, and I need some HD shocks anyways.
Americas Tire has been really good to Us over the past 10 or so years, bought a bunch of tires from them, even though I used to work at several major chain tire stores, the up-sell pressure seems minimal there.
I found a 4" lift kit from Rancho, but that adds about $1500.00 to the cost.
Probably stick with some 385's and some cool wheels I saw at Pomona Off Road Expo.

Haven't had to use the ABS. Yet. :wink:

But you're right, it's not safe, but it does promote safer driving. :shock:

We will be getting a lift, just not right away. (Money mostly)

I have plans for a 4" lift kit also, and some steps, BUT I can't do it all at once!!
$1500 for a lift kit, ??? for the steps, $1200 + for the tires/wheels is a little much at the moment.
I need the tires most, the tires on it now SUCK and the rears are 3/4's worn out.
and on top of that My beater Nissan daily driver needs tires also!!

Thanks for the info.

Next question:
I am looking at some 285/75-16's load range "D", the 245/75-16's I have now are load range "E". The 285-D's have a higher weight capacity than the
245- E's, so weight capacity is not an issue?? Anyone else have any real life experience with dropping down a load range?? I see most of the larger sized tires only come in "D" ratings, at least all the ones I looked at.
Thanks in advance.

Bob, BFG just came out with a 285-75R16 in a E rated KO tire. I just put them on my 2500HD and love them. They have a rating of about 3800lbs and what a difference they made, I just got to use them towing for the first time last weekend.

http://www.bfgoodrichtires.com/assets/p ... _ta_kd.pdf This sheet say 3Q, but they was 2005.

I dropped down to "D" rated tires (BFG A/T KO's) when I lifted my truck and never noticed much of a difference from when I had "e" rated tires. Then again, I was maxed out in towing capacity (3/4 ton Chevy HD and WW FSC2800 w/ four full size quads, water, gas, etc) with both, so I doubt I would have noticed the tires affecting things much.
The BFG's were about the best tire I've owned, and wore beautifully. They're quiet on the pavement (relativley speaking), and held up beutifully to the towing duty I subjected tehm to.

I saw that they had the "E" rated tires on there website, I was going with the Goodrich tires anyways, so I will check them out at the tire shop.

Sounds like your a "little" heavier than I am, I have a Thor Wanderer 247WTB, which is a 24 footer, with 2 quads and 1 bike plus the usual fluids and a Wife that takes enough stuff for a month!!.
I have run some 12.50x33x15's Goodrich's on Our old Dodge, they wore well and rode better than any other tire We put on her, so I think I will stay with them.
Thanks

Yeah, we're a little heavier, but it sounds like our wive's share the same packing philosophy! I ran those D rated BFG's for two years straight and absolutely loved them. I say ran because I'm back to "e" rated tires yet again. Not because the others wore out. I got a new truck! It has e rated Continentals on it from the factory, but as soon as they're worn, I'm headed back to BFG's. Maybe a few burn-outs would speed that up a little..."gee honey, I don't know why the back tires wore so fast. Well, time for some new ones!" RIGHT...

Went with the BFG 285/75/16 "E" tires,
only got about 12 miles them and NO towing YET, BUT they seem to have a MUCH smoother ride than the stockers.
We did have to crank up the torsion bars and re-align the front end.
