Load Range E Trailer Tires
I have a 2010 fifth wheel with 4000lb axles, had issues with load range D tires when fully loaded.... no axle problems... would load range E be too stiff and make the ride for the items in the trailer harder? Does anyone recommend load range E 225/75 R15 Tires?

Ours was fitted with lr d from the factory. They looked overloaded and were the fr china brand.I had the dealer change them out to lr e Marathons (which I supplied) before we took it off the lot.The lr e's were also 16" and on dexwheel steel wheels as well. the e's are well over the axle capacity where as the d's were only about 80# short of full capacity.A properly inflated lr e will ride a lot better than a d that is blown out from an overload!

No they will not be to stiff and should be on the unit from the factory . the factory does not care if the tires are maxed out with full load .
You should and the E-load tires will work wonderfully

Go with E
Our TT came with Load Range C tires, which was insane. We lost two on the road, along with associated damage. I upped them to Load Range E (Carlisle) last year and so far have had no problems. Don't think stiffness should be a serious issue; many roads (such as I70 across Indiana) are so bad anyway that the problem isn't vibration, it's heavy shocks.
Interesting that on the dealer's lot, most of the newer inventory I've seen recently has the version of tires that I upgraded our trailer to have!

I switched from LR D to E's last year with Maxxis m8008's. So far so good-I'm a happy camper.

Yes, I too am a Carlisle tire fan. Have many thousands of miles with no incidents.

I had load range d on on my old 5er a 27.7 Jayco as well as my current 30lswb Wildcat and put e's on them both. Had a blowout on the Jayco on our first trip to Lake D'Arbonne,La and have had load range E's after that. Go with the E's !

We put load range E tires on our 2014 Windjammer, after blowing out one of the original equipment load range C tires. Immediately, I noticed how much better the trailer pulled...stiffer sidewalls eliminated all the "wallowing" and side-to-side rolling of the trailer. I would highly recommend going with E's on your 5er.

This past Saturday we changed out our factory installed load range "C" tires to Michelin XPS load range "E" tires, as well as Sendel 16" wheels.

Our 2504s came with 205/14 LRC tires. Out yellow sticker weight is 4660 lbs. would it help with D or E tires? New to rving but I know that they can get heavy very easily. I was thinking more from a towing stability standpoint. Would E tires be too stiff? Any thoughts would be appreated. Jay

E rated tires might be a little too stiff for your trailer. D rated would certainly be OK, but with 4,660 lbs, your Cs should be OK. Ours came with load range C on a trailer with an empty weight of around 8,000 #s

Thanks. I think if my empty weight was 8000lbs I would want E range tires also. I am hoping that we top out at 55-5600lbs. We have always had boats and I have done my best to keep them as light as possible to avoid slowing the boat on the lake. Little things like plastic plates, lightweight pans ect. Jay

Rockwood tends to skimp on tire / frame clearance. Check yours !! C is too light, go D minimum on your Rockwood.

We upgraded to D load tires and like them. We were cautioned about going up to E load because the rims may not handle the added tire pressure. Did you upgrade rims too?

For our case, it found it a major challenge to get any information about ratings for the rims. I asked, but had no response from the rim supplier. After a lot of looking I finally found one web site that listed pressures, and that indicated that we should be OK with our E rating tires rather than the original Cs. Not beyond that, though. The combined weight capacity of the C tires on our trailer came to substantially less than the weight of the trailer; the ONLY way the numbers worked at all was considering tongue weight. But that left no safety margin or consideration for the extra abuse of shock loads on some of our crumbling highways. As a rather conservative engineer, I'm appalled at the lack of design margins. It's no wonder we lost two tires (with collateral damage) on the road before I upped the tires!

a few good e load tires for 15" i use the Hercules brand rated at 2830lbs your rims will be rated the same no worries there and if it feels to stiff you don't have to run max psi if your not max load maybe 75 psi will work with your load
