Rebus Posted May 13, 2013 Report Share Posted May 13, 2013 I'm hoping someone can point me in the right direction on this one... I am needing to replace the (far too quickly) worn out Kumho tires on my DJ. Unfortunately, looking at the door jamb placards, I was not able to find the load index and speed rating requirements with the tire info - just found tire size on both placards. Online, most of what I can find states 100H, but, as far as I can tell, these are unofficial postings here and there. It seems that many tire search engines (Michelin, Goodyear, etc) also show the same figures. However, a handful of tire stores (Discount Tire and some locals) show that a 'T' speed rating "meets or exceeds OEM specifications." Then, I decided to actually look at the tires that came on the rig from the dealer - I know...I know...I should've started there . Anyhow, turns out they are 100T rated. So, that brings me to my actual question...what is the official load/speed rating requirement for the 2011 DJ? Thanks! Quote Link to comment Share on other sites More sharing options...
senah Posted May 13, 2013 Report Share Posted May 13, 2013 The info is located in the operators manual under "Starting and Operating". It's all there. The maximum load is listed on the placard which includes recommended tire pressure. Inside drivers door pillar. If you don't have the manual, download it from dodge.com The speed rating all depends how you plan on driving your vehicle. My Challenger tires are rated for at 147 MPH, but for a Dodge Journey that's a little over kill. Most passenger tires are rated well above the safe limit and you should not even have to worry about it. Quote Link to comment Share on other sites More sharing options...
Rebus Posted May 14, 2013 Author Report Share Posted May 14, 2013 Unfortunately, neither the manual, nor the door jamb placard, include the minimum required service description - load index and speed rating designation (the requirement for tires that is a specific number/letter combination, e.g., 100T, 102T, 100H, etc). There is much discussion about maximum vehicle load in the manual, but that doesn't directly translate to the tire load index or speed rating specification. The only place that I can find the tire load index and speed rating, as far as I can find on the DJ, is on the tires themselves, which show 100T. Therein lies the issue. From what I have been able to find, tire manufacturers show that the OEM requirement for the DJ is 100H, which would mean the tires that came on the vehicle from the factory were not rated at or above oem requirements - which, if this is truly the case, I will have to talk with Dodge about rectifying. My current issue is that I am trying to find out if the oem requirement is, in fact, 100H as stated by tire manufacturers, or if it is 100T, matching the originally installed tires, so I can get the correct tires installed without having safety issues.

Rebus Posted May 14, 2013 Author Report Share Posted May 14, 2013 UPDATE: I have contacted Dodge customer service about this. They have escalated my question to their 'technical team' and will update me when they respond. If, in fact, the oem minimum requirement is 100H, I am going to request that they replace the tires that came on the vehicle from the showroom due to the fact that they do not meet minimum specifications. Heck many 3rd party tire retailers won't even install the same tire that came on the DJ from the showroom because of this. Why would Dodge do it?

senah Posted May 14, 2013 Report Share Posted May 14, 2013 (edited) The 100 rating for the tire you mention is 1764 pounds per tire x 4 = 7056 pounds. You don't need to worry about the minimum required, as long as the tires exceed your maximum GVWR. Your GVWR is: Five passenger Vehicle, FWD 2.4l 5005 lbs, or Seven-passenger Vehicle, FWD 2.4l 5250 lbs. So, 7056-5250 = 1806 pounds left for passengers and loading. Speed rating: H = 130 MPH T = 118 MPH I highly doubt you'll be driving over 100 MPH in a 4 cyl Journey. Edited May 14, 2013 by senah Quote Link to comment Share on other sites More sharing options...
Rebus Posted May 15, 2013 Author Report Share Posted May 15, 2013 (edited) That's all true; however the issue is convincing tire shops to install tires that don't meet the OEM minimum requirement as per there data. They just won't do it... Edited May 15, 2013 by Rebus Quote Link to comment Share on other sites More sharing options...
Rebus Posted May 16, 2013 Author Report Share Posted May 16, 2013 (edited) Wow, this just gets more and more frustrating...The response from Dodge is that the load rating should be 102 and the speed rating should be H. So, the 100T tires that came on the vehicle are apparently sub-standard? I have now asked if, being as how the oem tires are below spec, Dodge will replace them. This is just crazy.
