Yes, the 15x8 ET-19 Razor clears the factory JK factory brakes

Please excuse the 6-lug Razor photo we have pictured on our site. We do not take shots of every single bolt pattern.

You're likely rubbing on the lower front bumper/valence. You can easily trim the area where the tires are rubbing.

They should not rub even with no lift. Mine or my wife's jeep do not rub, my jeep has a 2" lift and hers has no lift, neither rub. I now currently have 35x12.50x15's on level 8's with 3.75 bs and no rubbing.

Don't worry about the bolt count in the picture as long as you order the 5x127 it will bolt up. I'm pretty sure -19 will work, but DT will know for sure if he chimes in again.

Espo78 Until a few weeks ago Discount Tire had no problems recommending or selling you a 33x12.5x15 Duratrac. They have now updated their policies and causing undue confusion for people. Buy them elsewhere if that is what you decide to run. They are great tires and I love them on my Jeep.
08-21-2014 06:36 AM
AGNP2013 I did some research… mine is 2013 JKU Sport S which GVWR (gross vehicle weight rating: maximum operating weight including passengers and cargo) is 5400 LB. According to a load index chart, one original tire (P255/75R17 113) can carry up to 2535 LB and 33x12.5x15 108 can do 2205 LB. I do not know this way is correct but I feel 33x12.5x15 is still safe for Sport S because each tire can maximally load 2205 LB. 2205 LB x 4 = 8820 LB which already exceeds the GVWR (5400 LB). What do you think? I have never heard anyone who runs 33x12.5x15 on their Sport S has any problems. Please, correct me if I am going to be dumb.

Espo78 I love discount tire, they've always been good to me and treated me right. At this point though I'm going to have to suggest using a different vendor, or just ordering the tires online without specifying what vehicle they are for. It kills me every time DT says you can't run a 33x15 Duratrac if your Jeep came with one tire instead of another. It's just bad information and not based on the real world. It's based on some lawyer trying to define what is "safe" across a broad spectrum of vehicles and tires and has little real world evaluation.

These are Discount Tire's misguided standards, and do not apply what other vendors feel is safe, or what is actually safe in the real world.

Thanks.
Thanks for the message. If your factory tire was specifically a P255/75R17 with a 113 load index you'll need a tire with a 109 load index or higher to meet Discount Tire's standards for a replacement tire.

It sounds like this is what you have but I would recommend looking at the placard in your driver's door jam. It will tell you exactly what tire came on your jeep from the factory. There are trim levels that come with LT255/75R17C 111 load index tires and these models do meet our load index requirements to run the 33x12.50R15 108 Duratracs.

To avoid the confusion, if you have a local Discount Tire near you please stop in and we'll be happy to double check this for you. If not, give us a ring and we can make some recommendations over the phone. 1.888.459.4080.

Do you have a 6spd or Auto. If you have 6spd with your 4.56 whats your rpms in 5th gear at 65mph?
08-15-2014 11:07 PM
Espo78 When I had the stock goodyears I parked next to a TJ on 33x12.5x15 Duratracs and the height was identical.
08-15-2014 10:43 PM
TAG1 I know we had this before, and I checked my speed with an GPS, it's dead'on. What I did not think about is how low the 33" will be on the car with the load. I will put one SRA back on tomorrow morning just to see what the difference in height on the car is. I like to think that the 17" SRA is taller with a load on the tire. Just a thought......
08-15-2014 10:18 PM
Espo78 Its been mentioned before. the Duratrac specs out to the same height as the factory Wrangler SRA tire. It's just wider and has the illusion of being taller due to the smaller wheel size. It's nice because it won't mess with your gearing or speedometer.

Also one point that looked funny is that the front that has the load of the engine is taller than the rear with out the load by an 1/8". When I measured the spare it's about 32.25".

Discount Tire Thanks for the update TAG1 I'm sorry if there is still some confusion. I'm out of the office until Monday. I'll give you a ring Monday.

TAG1 So from what I know after speaking with the DTD Technical Expert, I been told that the only Jeep that is a problem is the Sport S that has the 255x75x17R- 113S OEM. It is not a problem that is related to the car weight but to the tire that has been installed OEM from the factory(makes no sinse at all, but it's DTD's policy). If the tolerance is taken off a 113 tire, the minimum drop down will be 109….so all 33”x1250x15 will be too low by 1 since they are all 108’s. Again that is the way their system works and not the norm calculated based on the weight of the car that is the same as a Base Sport Model! So after talking with the Technical Expert from DTD I been told that they like to have my tires back, and will work with me to put me in a different tire. I was told that a Customer Service Rep will give me a call to work with me to change the setup.
Now the hammer….. when the Rep called on Wednesday, he told me that he has been told that I like to upgrade my tire (what I didn’t) and I told him that I’m happy with what I have but been told that DTD wanted the tires back since it’s not to their standard. He told me that if I’m happy with the setup he don’t care if I run this tire. He also told me to send him all the mails that the Technical Expert has sent me since it looks like that there are some misunderstanding about the topic…..”No kitting”. I told him that most of the topics had been discussed on the phone. I just thought that I would share the information I have with the forum, since it looks like they have some internal problem. I called the Technical Expert today but he is on vacation, so I left a voice mail to call me next week. I will let you know if there is anything positive coming out from this.

Thanks TAG 1

Espo78 I'll check with my sources at Discount Tire when I can. I had a tire replaced about a month ago and they never mentioned a backorder, of course they had the tire in stock also.

I'm beginning to think DTD is purposely steering people to a more expensive 17" wheel/tire combo on purpose under the guise of "safety" and that concerns me. I love Discount Tire. I purchased all 5 of my 33x12.5x15 Duratracs from them locally, with tire replacement certificates and never had an issue. This new change in practice is not good for business.
I been told by 4wd.com that they can not get the tire until end September...on back order, and this has been in June. The gave me my money back after one week. I think there is more to the story...!
