5114 is 51st week of 2014. I'll leave the other info for those more knowledgeable than me.

I didn't find the specs for your model year Outback, so I used the 2014 specs. I'd guess they are very similar. To answer your questions, the date you quoted, 5114 is the 51st week of 2014, or the week of Christmas, 2014. So they are, as of now, 2 years, 4 months and a few days old. You didn't give the brand, but I'd guess Trailer King. They are, by most accounts, "sub-par tires". Most of us don't really trust them.

The load rating for 225 75R15 LRD tires @65 PSI is 2540 per tire.
The load rating for 225 75R15 LRE tires @80 PSI is 2830 per tire.

Given your trailer's GVW of 7500 with about 12% on the tongue (900) that leaves around 6600 pounds on the axles. That equates, assuming the axles/wheels are equally loaded, about 1650 per tire position. With LRD tires, you have about 35% reserve capacity and with the LRE tires, about 41% reserve.

Either tire would serve you well, so it's essentially a matter of personal preference, which is cheapest (sometimes a particular size/LR is on sale and cheaper than lighter tires) and availability. Right now, WalMart has some excellent pricing on both LRD and LRE Carlisle tires.

Will probably replace them especially if oem. OEM tires are by size only. Brands are never mentioned in the regulations. However, the trailer manufacturer may tout a particular tire brand in their advertisements for OE tires and any available options they may recommend.

Would like to get load range E
Wondering if possible to go a little bigger? Or if i can get load range E in this size. Yes, that size is available from numerous manufacturers in LRE.

Any info is appreciated, have had lots of horse trailers and flatbeds but no travel trailers
To be able to take advantage of higher load capacities provided by a Load Range increase, your OEM wheels/rims must be able to support the new load capacity and psi rating of the higher load capacity tire. Otherwise, you just have another LRD tire.

LR-D tires in that size will carry 2540 lbs each at 65 PSI. I just did a quick search for your trailer's GVWR. Around 7500 lbs. Fully loaded (and considering 12% tongue weight), each tire has approximately 1650 lbs of load to support. Believe it or not, the reserve carrying capacity of the OEM tires is more than sufficient on your coach. It's more than 50%. An LR-E tire would increase it to 2830 lbs or 71% reserve capacity. Personally, I would save the few dollars and just buy LR-D tires from a reputable brand (Carlisle...cough...cough). You have no reason to go bigger with your tire/wheel size. Good luck.

Your tires are OEM. They are Trailer Kings. They are over 2 years old.....time for new tires!!! Carlisle Radial HDs have served me really well. You don't need an LRE.

someone on another forum with a 2014 looked at his rims said they are LRE capable so guessing mine are

looking on discounts site i am trying to decide between the CARLISLE
RADIAL TRAIL HD $96 each

and the GOODYEAR
ENDURANCE $121 each
both are load range E

tread depth is 9 on the carlisle and 8 on the goodyear.... but supposedly the goodyear are made here in the US
carlisle china

Discount Tire can get more tires that what is listed on the website. I just got a set of HD's in LRD from them even though the website didn't list them. As a side note Wal Mart has them for $61 each and Discount Tire will match their price!

For the price you can get the Charlie's right now it is hard to pass up on them!

I put Carlisle on my 5er (2nd 5er and a TT also) last Dec. I'll put 1 more set of Carlisle on as GY just began producing the Endurance and I'll want 5 years of reviews before considering them. I'm no fan of GY truck tires, GY G614 trailer tires are great but require 110 PSI and GY Marathon trailer tires will never go on anything I own.

You'll have to be careful with DOT dates with this size tire. I needed to refuse 3 sets in LRD from 3 different merchants because the DOT date approached 1 year. Seems many warehouses have aging inventories. I finally ordered a fresh set of LRE's from Walmart.com. They came in at about 90 days old.

Camping trailers are notorious for swapping whatever parts are available in and out. Never assume everything is the same in a model run trailer to trailer. Check the back of your wheels to see what they are stamped with as far as psi they can handle.

As another note, the Carlisle tires made in China are top notch and not the problems that your Trailer Kings are. They are made to much higher and regulated standards. Trailer Life had an article about their processes and practices if you search their archives.

WalMart's site is difficult to use. Here are the links to the two Carlisle tires. The pricing is the lowest I've seen anywhere.

Load Range D is $61: https://www.walmart.com/ip/Carlisle-...R15-8/55012157

Load Range E is $67: https://www.walmart.com/ip/Carlisle-...DxgI1uyfgX0wAw

At these prices, it's difficult to justify using questionable OEM tires. Just make sure your wheels are rated for 80 PSI/2830 pounds.

As a sidenote, the Goodyear Endurance tire line is brand new. There is only about 3 months of "customer use" available. The tire line may prove to be very good, or it may prove to be a repeat of the Goodyear Marathon. It's just too early to tell and there's no data to indicate how they will last. Somebody has to be the "guniea pig" but at almost double the price of the Carlisle's, I'd let someone else take the risks......
