Yes, 36 cold psi all four. I try not to worry about my MPGs too much but I probably average 13-15 mostly city miles.

Re: 275/65/18 Duratracs on Mopar Wheels!

Sorry if this is a dumb question but I'm a relative neophyte when it comes to tires. To you guys that have purchased the Duratrac's why did you go oversize? Is it only to get the extra bit of ground clearance? Or maybe for appearance? If I stick with the same size Duratrac's as my Michelin Latitude's (ie 265/60R18) on the stock wheels will my spare tire theoretically fit in the rear with the lid fully closed? Is there any downside, other than ground clearance, to sticking with the standard tire size?

Thanks for any insight you can provide.

For the same reason you are thinking about duratracs instead of lattitudes. Only ours will have a bigger contact patch to the ground and therefore get more of that same benefit you are looking for, in addition to the extra ground clearance.

Afterall all.the full-time 4x4, terrain select and offroad adventure options are ultimately only as capable as your tires.

Re: 275/65/18 Duratracs on Mopar Wheels!

I really want to go 275/65-18 but without an ability to change tire size by tuner I look to go with the 265/60-18 versions with 0 offset wheels in hopes I don't need the RRO lift which I was going to get if a tuner would work. I plan to contact Superchips to talk about coming out with a tuner for our jeeps since they have one already for the 3.6L wrangler. Hopefully I can convince them to come out with one and run the setup I want.

My experience is that my speedo reads 1mph off at 40mph, 2mph off at 60mph and 3mph off at 80mph. So it was easy for me to choose traction grip and ground clearance and not worry about the small error.

Thats not that bad but I would have to teach myself to run say and 70 instead of the usual 5mph over. But we shall see after I call Superchips tomorrow. Going to ask if they would need a certain number of people committed to get a tuner in the works. Since Diablosport doesn't care to fix the issue they have with theres or just plain can't. One guy on diablosports forum has been waiting for 5 weeks for a reply to correct it.

Re: 275/65/18 Duratracs on Mopar Wheels!

Is everyone running the lt or p version of the duratracs. I know sometimes the P sizes will run smaller than the LT

Picking up my 2011 4.7 Overland tomorrow and going to order the 18 rims while i'm there. Was going to try 18 jk rims but love the mopar rims and to much.

Thanks for all the great info on this forum!

I can't directly answer, but the tire I went with (Mich AT/2) also came in 275/65/18 in either a P or LT. I went with the P, as the load carrying capacity of the Jeep didn't warrant the extra capacity of the LT. I didn't want the harsher ride or the additional tire weight.

275/65/18 Duratracs on Mopar Wheels!

And I went with LT275/65/R18 Duratracs to be heavyer duty for off roading with lower PSI(15-18) and able to stand up to sidewall rock rash better.
Comes down to your own price/purpose/performance preference.

To put it in simple terms, the LT version (Light Truck) is for carrying heavier loads, it's heavier and has a sturdier sidewall..so if you intend to tow heavy loads then perhaps it may be a good idea...if you don't intend to do any heavyweight towing then there's no need for it, you're just adding more weight and slowing down your jeep.

Re: 275/65/18 Duratracs on Mopar Wheels!

I am about to purchase my RRO lift kit this week. I am going to stick with the 275/65-18 instead of stock size. If I have to change my driving to have the tire I want til a tuner comes out that works I will. It's not like my summer car that runs 2mph slower which keeps me from the cops but I will make due. Don't think I will ready before snow hits but I might have to put the snows on the summer car.
