I'm new to the pup community (got our 1st pup 4 wks ago) so I was not sure about this. 1996 Coleman Sun Valley GVWR = 2500 lbs GAWR = 2200 lbs Duro Load Range C tires: Load = 1360 lbs ea (2720 lbs total) Duro Load Range D tires: Load = 1660 lbs ea (3320 lbs total) I ordered a pair of Duro Load Range C tires yesterday, they give me a "cushion" of 270 lbs over the GVWR. Is that enough of a safety cushion or should I have ordered the Load Range D tire ? I don't normally load the pup to it's GVWR and the LR D tires have a larger than stock sidewall and OD but I wanted to get a stock sized replacement. So I want to hear some input from you guys on this. TIA 1996 Coleman Sun Valley 2008 Dodge Ram 1500 QC V6
I personally would have gone with load range D tires if they fit. The D range tires should be longer lasting and in my opinion a 270 lbs cushion is not enough... ______________ 2004 Expedition & 2000 Palomino Mustang SL-SG-FT http://www.thecampingchild.com
I agree with theseus I would have gone with the load range D tires as well. 1. 270 lbs is not enough cushion for me. 2. When at proper air pressure they should run cooler.

Load range D cost only a few dollars more than the Cs and to me would be well worth the extra dollars. Allen 2004 Fleetwood Utah
Thanks for all the input so far....... although now I'm more confused. lol This is from Fleetwood on the 2008 Sun Valley: GVWR = 3500 lbs (My 1996 Sun Valley has a GVWR of 2500 lbs) The factory equiped tire for the 2008 Sun Valley is: ST185/80D13 Please correct me if I'm wrong (I probably am) but don't the ST175/80D13 tires come in LR B (1100 lbs load ea) and LR C (1360 lbs load ea), and the ST185/80D13 tires are LR D (1660 lbs load ea) ? If so, wouldn't that mean that Fleetwood is equiping their product with tires that are 180 lbs UNDER the GVWR capacity ? I can't see why they would do that ? Is there a ST185/80D13 LR E ? Maybe that's what Fleetwood equips the 2008 Sun Valley with ? 96 Coleman Sun Valley 08 Dodge Ram 1500 QC V6 1 Wife / 2 Kids / 1 Camping Dog Edited by - TX_F2 on August 07 2008 14:07:05
Technically you would want the tires to be at or over GAWR (Gross Axle Weight Rating) So with LR C on your original post you would have a cusion of 520lbs. For the 2008, if you assume 10% for tongue weigth, the GAWR would be around 3150 lbs so LR D tires would work. You don't want to overload your axle any more than overloading the tires. My older pup doesn't list GVWR, only GAWR. Now all that is in theory. I actual run LR E (10 ply bias) and I could get by with LR C. I'm all for higher is better as tires go. <img src=../Images/icons/icon_smile_pu.gif border=0 align=middle alt="PopUp"> '94 Coleman Sequoia <img src=../Images/icons/icon_smile_suv.gif border=0 align=middle alt="Tow Vehicle"> '00 Toyota Sienna

The "D" in the ST185/80D13 tires refers to the fact that it is a bias-ply tire, just like the "R" in 265/70R16 indicates a radial tire. The Load range in this size is indicated separately, and corresponds to the number of plies the tire carries. Load range C=6 ply, load range D=8 ply. The 'D' tires are more difficult to come by, don't know if there is an 'E' in this size. __________________________________________________________ 1999 Jayco Eagle 12SO pushing a F350 PowerStroke CrewCab 4WD long bed monster Here are my Jayco lift docs, they're now on the Portal for you!

mgwerks: Thanks for the reply. I probably didn't use my words well though. I knew that the "D" meant bias-ply, what I was unsure of was if the LR D that the 3 replies I got sugessted to use were rated at 1660 lbs ea. 96 Coleman Sun Valley 08 Dodge Ram 1500 QC V6 1 Wife / 2 Kids / 1 Camping Dog

Now I know that you go by the GAWR and not GVWR. For some reason I got confused on which to go by. I'm all for getting more then you need, but I think a 520 lb "cushion" should be good. I will just stick with the LR C tires then. Thanks for everyones input. 96 Coleman Sun Valley 08 Dodge Ram 1500 QC V6 1 Wife / 2 Kids / 1 Camping Dog
