Spare tire solution for Goodyear Duratrac 275/65-18

Credit goes to wahoo (http://jeepgarage.org/member.php?u=8581) and this thread (http://jeepgarage.org/showthread.php...light=duratrac) for planting the seed and blazing a trail for us QL buyers who wanted some proper tires. As everyone has agreed, these tires look awesome on the GC.

For anyone interested, I used a bit of trial and error with a tire size calculator and came to the conclusion that a 255/70-18 spare should fit in the rear compartment and almost exactly match the diameter of the 275/65-18 Duratracs.

I was about to have a set of Duratracs put on my GC and wanted to be sure I could still have a useful full-size spare to work with before I put them on. Discount Tire has a nice tire size comparison calculator on their site, and it helped me find what I hope to be a good solution.

The BFG Rugged Terrain T/A P255/70R18 112T ORWL (as straight from Discount Tire's site) has a diameter within .01" and a cross section narrower by about .8" than the 275/65-18s. Also there aren't any sidewall tread-blocks which should help clearance.

I saw some guys mentioning that they fit 265/65-18 Wrangler SilentArmors in the back and could still close the floor; at least one bin having to get pulled though. This BFG has the exact same cross-section width as the SilentArmor mentioned, but the diameter of the DuraTrac 275/65-18.

I don't really care if the bins are in there or not, personally, as long as I can get my VIAIR 300P and other recovery equipment stuffed around it.

That does remind me, a VIAIR 300P plus it's hose does fit in the space one of the storage bins would take up. You can't use the carrying bag, but it's a nice upgrade with much higher duty cycle over the 90P that a lot of others have recommended. This isn't taking into account the larger BFG in there, but it seemed to have some room to spare (pardon the pun) with the OEM tire, so it should still fit with the larger BFG in there.

I've had the Duratracs on for a few days now. So far I really like them. Road noise is obviously increased, but it's completely tolerable. It is after all a true off-road/on-road tire; compromises must be made. With the windows up I don't even find myself turning up the stereo any louder than I had it before.

They seem a little more sloppy handling-wise than the OEM tires, but once again, typical compromise for this kind of tire. By no means do they feel unsafe. I'm sure I'll be praising them during the snow season in the Colorado mountains this winter.

I'm running 40psi right now (per shop recommendation) and going to see how they wear in the first 5k miles.

I ordered the BFG tire and should be getting the spare mounted this Friday. I'll let everyone know if my calculations all worked out, and post some pics.

The BFG fit perfectly. There's no room for the bins as I suspected. I don't feel they're terribly necessary anyway. The lid closes just a tiny bit snug, but I do keep a set of jumper cables on top of the jack in the center that may be making the clearance a little tighter.

Everything I had in there stuffed around the tire fit just fine around the larger size, but YMMV.

I feel a little better prepared for some off-roading now.

Anybody in the Denver area want a spare, never-been-used Kumho? I kept the original tire, but I'm starting to question why.

I'll be getting a spare off a Wrangler, 255/70/18. There's lots of them out there and some are almost giving them away. Same diff about .1 with the P275/55/20 I put on my Wifes Overland.

What did the shop say about the snow performance of the Duratracs? I live in Vail and have been reading up on that tire as well as the Hankook Dynapro ATM which received great reviews on Consumer Reports.

I asked a couple of guys in the shop who volunteered that they ran them on their trucks and loved them. They claimed snow performance was great.

Duratracs are branded with the severe winter service symbol which does require them to meet pretty stringent standards for winter use, but only time will tell.

What size BFG is that in there? The stock size or a larger size?

As noted in the OP, it's a BFG Rugged Terrain T/A P255/70R18 112T ORWL.

My post was a little long though. Kind of gets lost in there.

Re: Spare tire solution for Goodyear Duratrac 275/65-18

captdef what other tires did you look at? I have a Larado with ORI and the 5.7. I ended up getting the SL but I have no been happy with them at all. They aren't great in the snow for me (I have messed with pressure). I ran BFG AT KOs on my last 2 jeeps (WJ, and XJ) which I loved but figured I would save 10 lb per tire to see keep the mpg up. I am either going to head back over to the trusty BFGs or the generals that look like BFGs. How do you like the performance (dry, wet, and snow) since we have been running then for a bit? How is your MPG doing? Sorry for all the questions just looking around for something better.
