Hartland Radial ST Guinea Pig

bsmith0404 · 07-09-2016, 01:05 PM

Okay, I guess I'll be the guinea pig for these tires. After my last trip and losing one of my Carlisles to a nail I went back to Discount Tire and ordered a replacement. I went back in today to have them installed (ordered one to replace the blown tire and one for the other tire on that side with the plan to move that LRF tire to the spare which was still the OE LRE tire).

When I arrived, we found out he had ordered LRE instead of LRF. It was going to take until late Monday or early Tuesday to get the LRFs in and I'm leaving Tuesday morning. They had some Hartland LRGs in stock.

At first I didn't think they would work since most LRG tires take 110 psi of air. These are only 95 psi, same as the LRF Carlisle. DT worked a good deal with me (I buy a lot of tires from them) giving me $100 each for my 1 year old Carlisles on trade and replacing one of the tires for free under the tire certificates. I normally don't buy replacement certificates, but with trailer tires I figured they're probably worth it.

So far they look like a decent tire, very similar to Good Year G614 and Sailun S637. For those that wonder, they have an N speed rating (87) there is also a version with M rating (81), both have a 129 Load Index (4079 lbs). Time will tell if these are a good tire or not. One thing is for sure, it's serious overkill on load rating with almost 1,000 lbs per tire to spare so realistically, I shouldn't have any problems with them.

Are these 80 or 85 series?
What did they cost?
Any idea what they weigh? (For reference the Sailun's weigh about 61 lbs).

Anyways interested in a *good* set of tire options.

These are the 85 series tire. I switched to that from the OE 80s when I put the LRF Carlisle tires on. I'm not sure on the weight, but they are pretty beefy. They definitely weigh more than the Carlisle does and took a good bit of effort to lift them into the back of the truck. DT price is $160 each, of course with getting $100 each back on my 3 good Carlisles and one for free with the replacement certificate I was able to get all 5 tires, mounted, balanced, steel valve stems, and replacement certificates for $500. I know I'm good for at least 3 years with the certificates. Knowing that my TST 507 works as advertised also gives me some additional piece of mind.

Well played! Looking forward to hearing your thoughts on their lifespan and pulling characteristics. It's always nice to have lots of capacity headroom- I hope they treat you well.

Good deal. Glad you got away without major damage.
The diameter change of 235/80 to 235/85 is .9". So you lose half of that on tire-to-deck clearance. Something to watch - on the Carbon, it's pretty tight already, we'll lift the axle before trying to carry fully loaded because we switch to 85s.

If I recall right, frame manufacturers recommend ~3" clearance tire to deck.

I have plenty of clearance for the 85s. I checked that before switching to the 85s last year. I've put over 7k miles on since the switch and no signs of contact.

Interesting tire. First time I've seen it on Discounts web site. Has an interesting thread design as well. Nice wide channels for water to escape.
Since it is G rated at 95psi instead of 110psi it must be a fairly strong tire and they have confidence in it. I wonder if they have enough confidence in it to run at lower pressure like Sailun.

I was thinking the same thing. I was really surprised when they said it was only 95 psi. I made them pull one down to verify. I'm a little nervous since there isn't much information about it available. I should have changed my wheels at the same time, but wasn't ready to part with another $500 yet. I guess next year I'll pull them again for a balance check and change the wheels then. I just found Sendel T11BMs on Amazon for $80 each with free shipping.

Not sure on the lower psi, since information seems to be hard to come by on these right now.

I've got another year before I re-tire, but those may be on the short list.
My 6 lug hubs don't leave much choice for upgrading wheels. I found a couple on eTrailer. Just more $.
My Maxxis LR E gives me plenty of reserve capacity but running a LR G sure would make me feel better. Running Sailuns at 80psi is likely where I end up.
