Trail Digger M/T, sidewall concerns?

So I'm going to be stepping up to 35s soon, and have been looking around at prices. I found these, Hercules Trail Digger M/Ts. The only problem though, is that only a very few select sizes have the stronger 3 ply sidewalls, and it seems that the sizes they chose to have 3 ply are all odd sizes that not many folks would run? The 315/75/r16 that I want do not have 3 ply.

http://www.onlinetires.com/products/...+121n+owl.html



I have read a few reviews on these tires, alot of folks seem to like them (especially the price/value), but some folks have complained about the sidewalls cutting easy. Problem is, I don't know when people are reviewing the tire how hard they drive on them. I don't drive super hard on mine, but I'm still somewhat of a newbie, so my tire placement isn't always ideal, sometimes they slide off into a situation that I wasn't intending to be in. I think I'd like the extra security of a strong sidewall, but man these are quite a bit cheaper, I wouldn't mind that either!

Is anyone here running the non-3ply version of this tire? Most of the trails I run are rocky and hardpacked dirt. I've not had to much trouble with my sidewalls, only a few minor cuts, nothing that goes real deep. Is it really a weak sidewall, or is it still pretty tough?

Should I be concerned about running these tires on rocks? These tires are almost literally $100 cheaper per tire than the Goodyear MTR Kevlars that I also have my eye on (particularly because of their claimed sidewall strength). Saving $500 would be quite nice, but I don't want to do it if I'm going to have issues with weak sidewalls.

Part of me thinks I'll probably eventually slash a sidewall sometime no matter what tire I have, so I might as well just get a cheap one because it will be cheaper to replace. But the other part of me thinks that It might not happen that often if I have better tires.

Thoughts? Experiences with these tires? My jeep is a daily driver, weekend warrior. Not a trail only rig.

Alright, well I placed an order for these, I guess we'll find out how well they do! :-)

Question for yall, I'm gonna be picking these up, is it possible to fit 5 35" tires inside of a TJ? I've already got the rear seat removed, think I need to remove the passenger seat as well? I have ratchet straps, and want to try and make just one trip. I've seen a photo of an LJ with 5 35" tires, but not a TJ.

5 35" tires inside a TJ? Um, no.

Put them on the hood and top of the Jeep and strap 'em down. Ain't no way they are going inside the Jeep if you plan to drive it.

I like the looks of that tire. And, for the price, you can afford to cut one or two and replace them and still be better off.

Yea, I took the passenger seat out today, I think I can get 3 stacked up in the back, and one where the passenger seat goes.
I have a soft top, wonder if it would be strong enough to strap a tire up on the top? I've had alot of lumper on the top, but that spreads the weight over the entire top. I'll just make 2 trips I guess, pick up the 5th one sometime later. Just so long as I can get all 4 done in one day, I can do the 5th later :-)

I've done 4 35's in the back without the rear seat so removing the passenger seat they should fit no problems. It wasnt easy but i put 3 up right across the back and then one flat across the top wedged in between the tops of the 3 tires and the sound bar. Strapped it down from there.

Hah, maybe I can get all 5, 4 as you suggest and 1 in place of the passenger seat. We'll find out tomorrow morning :-D

I think putting one on the hood might work if I only had to drive a very short distance, but I need to drive some 20 miles or so, I'd rather make a 2nd trip later on instead of putting one on the hood blocking my view of the freeway.

Well, they mounted nicely! They have a very tight fit around the lip of the outward bead, we had to use carpenter's clamps inverted (so that they press outwards instead of clamp inwards) to get the tire to sit over the face of the wheel. We didn't have to do that with my older Hankooks. I guess a side benefit of that, is that I'm pretty darn sure the tire is centered on the wheel :-D Gave it a test drive with 26psi, all is good! They are somewhat louder than the hankooks, but it's a much deeper tone, which is probably easier on the ears than a higher pitch sound.

Will report back after a few wheeling trips, should be breaking them in offroad next weekend :-)

They are probably a bit on the small side for 35" tires, they measured in at about 34.5"

I'd love to hear how the trail diggers compare to the hankooks.

The Trail Diggers do sing a bit louder than the hankooks, but it's quite a bit lower in pitch, so I actually can't say that it's much more noticable. It's probably louder for sure, but it's lower in pitch so it doesn't hurt the ears any more than before. I'm guessing the lower pitch is from both the larger size (slower rotation for the same given MPH) and the larger tread blocks than my old hankooks.

I didn't get a photo of us getting the outside bead set into the wheel, but it's pretty much the same as the photo of us getting the inside bead over the outside lip of the wheel with the inverted clamp. We tried and tried on the first tire to get it over without the clamp, we jumped on it several times and man-handled it quite a bit until we finally got it. But then for the remaining 4 tires we used the clamp (and beer), with the quote "work smarter, not harder" and it was much easier by far And for airing up the tires, we didn't use a ratchet strap or anything, I just used Blaine's advice and set the wheel outside up on a 5gallon bucket, and used my super slow electric pump, it did the trick perfectly and gave us a good 5+ minutes to crack open another beer per tire

Will be hitting the trails next weekend, and will report back! I am a little sceptical about the sidewall strength, but after talking with a few folks who are running these tires on some decent trails, I'm willing to take the chance. And I have a spare if needed. If I'm unlucky, I'll slash a tire. If I'm extremely unlucky, I will slash 2 and be F**ked, haha!

When we eventually get some rain here in SoCal, I'm sure these tires are going to rooster like crazy! I'll just be sure and wear my sunglasses and bring a jacket

And I must say, these clamps I purchased have been quite handy above and beyond what I initially thought I would be using them for. I've used them for lots of things on the jeep, they just keep giving and giving! Do yourself a favor, and pick up at least one of these. They can clamp or press up to 300 pounds, and hold it there for as long as you like. Better than I can do

Got a chance to take them out on the trails this weekend, they seem to grip very well! I ran them at 12psi (didn't check to see what they warmed up to), I am quite pleased with how they performed. They had a decent bulge to them at 12psi. Will try other PSIs on later trips. I was with a group of stock vehicles so we didn't get to hit any harder trails, hope to do that next weekend! These things do fling rain water and mud quite a bit, but I guess my thinner front flares don't really help that.

I'm still trying to find what street pressure I'd like to run these. The chalk test at 23psi says that they are still a bit over inflated. I'm not really sure I want to run much less pressure than that. I started out at 26psi (just as a first wild guess) and ran them that way until this weekend where I aired down to go offroad, now I'm trying them at 23. They seem to be just fine on the road at both pressures.

After being on the road for a few hours this weekend two and from the trails, I got a good feel for the tire noise over long distances. It's not exactly a background hum, you can hear them for sure. But it's not a piercing sound at all, it's quite tolerable even at 75mph with no doors or windows. I wouldn't hesitate to take these on long trips at all (well, just from a noise stand point. Not sure how well the tread wear is). And after a few weeks of driving these back and forth to work every day, it's not at all an issue for daily driving.

My gearing (4.10) does feel like it needs to be changed, but honestly it's something I think I could easilly live with for a while. 1st gear in 4lo (4:1) is still quite slow, and on the freeway the RPMs aren't TOO low, if I remember correctly at 65mph I think the RPMs are somewhere around 2200 or so in 6th. Not alot of power when it comes to a hill. It's quite livable for now, but I think a gear change is on order in the future some time.

after having been on several pretty good rock trails, I'm really liking these tires. They seem to be doing just fine. The edges of some of the tread lugs (particularly on the outside lugs) have a bit of ware from the rocks, but I don't think it's anything outside of the ordinary, my old hankooks did this two after a few good trails.

I have still been doing 12psi offroad, I may try 10psi next time, see if there's more grip to be had.

A little bit of an update! These tires seem to be doing pretty darn good! I've driven them across country on the freeways twice now. Including one trip which I diverted from a closed freeway due to Ice & snow, and I headed up into the mountains on back roads through the ice and snow. They probably aren't good tires on ice, but I did ok. And I've had them on lots of rock trails, they do just fine there!

I've been running them at around 10psi offroad for the passed year or so, and I've found that to be a pretty good pressure. On road, I've been doing about 25psi

The tread lugs seem to be taking rock rash quite well. I've got a few cuts in the sidewall, but nothing that' popped the tire so far. That was my main concern when I got these, how strong the side walls were. They seem to be fine
