Fuck it. I just ordered some of those Goodyear Kevlar things.

It's a great tread design, if not ideal for fast corners. At least I won't be worried in mud. I'll just keep them for general wheeling and day-to-day use. My problem is the name on the side and the dumb-ass Kevlar bullshit. It's no better than anything else.

Goodyear Wrangler MT/R "With Kevlar" reminds me of this:

I'll give Goodyear one more try. If they don't balance worth a shit, I'll be annoyed. I'm done with that shit in these small sizes. At least they won't rot like the BFGs.

I think Sears will take the others back. If not, I'll sell them. I'm almost certain I can make a profit.

HAHA, that was funny as hell. I do not know where you get your material but it's hilarious.

That's a great tire that's simply not made for my application. It's a bit slower than I'd like, but the biggest issues involve the aspect ratios that are available.

Nothing even close to what I want on a DII is offered, and that's annoying as hell. You're good if you own either an H1 or a Series, though.

The fuckers are also expensive over here for what they are, and replacements aren't always available. That's annoying. If these were produced a little fatter without being twenty feet tall, and were offered regularly at many dealers, I'd own a set for slower trips.

I really don't understand what's wrong with these manufacturers. So many great tires that would be used by many people just aren't available here, and I know damned well all the fuckers are or can be DOT approved.

As usual, it seems rigged; just like cars. America gets the leftover, cut model, and weekend tires. If you want anything serious, you've got to go well out of your way to get it.

Cheers,

Kennith

If you haven't seen it, a piece of your life is missing.:D

It's essentially a movie showing the world as viewed through "Kennith Glasses".

They do make a 8.25R16, which I guess it a little over 33" tall. They also make 235/85R16 and 255/100R16.

They all pretty much have 100% aspect, except that 235/85R16 obvisouly, so they are tall and skinny when compared to a lot of other tires out there.

The most common ones you see are 7.50R16 which is 32" tall, and 9.00R16 wich is about 36" tall, I think.

Yep. I was actually stoked to get some, back when they were even harder to get. Like '05 ish, when I had a much larger disco.


Then I road in and drove a disco with them. I decided it was a bad idea as soon as I got up to about 55mph.

a lot of people give a bad rep to great tires because they aren't properly balanced or there are other problems. XZLs will do 90mph smooth as butter.

I've never noticed anything wrong with how they ride, but I cannot really get over about 60mph without the engine screaming at me.

I had the MT/Rs mounted today. They need to be broken in, and I have to sort out pressures, but I don't think I'm going to dig them.

They actually balanced very well at just a few ounces a piece, and I can tell they will ride relatively smooth and quiet. I also expect they will be pretty damned nice in most trail conditions. I suspect I'll see dramatically improved mud performance, at the very least.

At least with this set, it looks like Goodyear FINALLY cranked out a quality tire out of the gate. :eek: The weights bounce around just enough to demonstrate acceptable quality control, rather than simply a lucky set. This gives me hope for the Wrangler All Terrain Adventure.

Even so, as I suspected, they just aren't going to hook in the corners, and I'm predicting poor gravel and loose dirt over hard-pack performance. I don't think they'd like washboards very much, either.

The lugs are simply too isolated, and the carcass is too flexible as a result of the two ply construction. I said it might be, and indeed it is. They invented a great new tread pattern, and slapped it on a tire with too much innovation for it's own good.

They should have kept the tread design, and wrapped it around a true three-ply carcass, with none of that Kevlar nonsense.

This is not a fast tire, even by off pavement standards. They will improve once broken in and pressurized appropriately, but I can feel it. I'm looking forward to trying them in different conditions, but I'll need something more stable to get back on the throttle and steering the way I like.

That missing full carcass ply disconnects the shoulders very noticeably.

I liked the Grabber Red Letter carcass much, much more. It was pretty much perfect from a construction point of view. Just a few modifications would sort that right out for my purposes.

I'll run the Kevlars for a while and see what happens. I'll fuck with pressures over the weekend. Once they are broken in, I'll take them to my favorite testing area and give them a genuine and honest chance to try things my way. :D

At least I'm finally in a new set of tires.

I am pleased to say, however, that my opinion of Goodyear may change a bit. They've earned more chances, as this is by far the highest quality tire I've seen them release in some time, and is one of the nicest tires of any brand I've handled in recent times. They've even sorted out that bullshit compound that used to annoy me.

I know why it's designed this way on purpose, and it's not meant for people like me. Don't think I'm coming down on them. I don't have nearly enough Rover to test their full trail capability, so I'll pass that torch to Dan.

One thing I can do, however is show them some Eastern NC mud. I can also push them through shallow sideways ruts in slippery conditions at higher speeds to report how they handle. Nobody may ever ask that question, but in the unlikely event that they do, at least one answer will be available.

Cheers,

I've got a good contact patch at 40psi on the MTRs.

The math suggests that 43psi cold should be okay, but that doesn't account for the asymmetrical tread pattern in combination with the effects caused by those decoupled sidewalls.

I'm definitely feeling it. Pressure isn't being distributed evenly, and the tires really don't know what to do when pushed in corners. It's not the tread pattern that's the real issue, it's the carcass itself.

These seem like fine tires, but I may have to move to something else.

Cheers,

If you want to sell the MTR - let me know. :)

That may well be the case. I'll run them for a little while and see what happens. At the very least, I can build up some cash to buy something different.

I can tell you right now, though, that these are purely town and trail tires, as far as I'm concerned. I couldn't use them for anything else. I'm finding it difficult to take them seriously.

The vehicle feels hamstrung.

Cheers,

Kennith

It is exactly the tread pattern issue, no matter how long you try telling yourself otherwise :)

There's more to it than that.

The shoulder blocks on these tires are wide and long; interacting in a rather clever manner with the tight circumferential blocks existing about three quarters across the section. The voids may be longer and wider, but the blocks are fat, smooth, and well supported.

This should be no worse in corners than any common MT. Indeed, so far as performance in corners is concerned, the KM1 was a surprisingly good tire, and the tread design of the Goodyears should be not too far behind.

The sidewalls on these MT/Rs are flimsy, and perhaps the worst offender is the apex above the bead. Not enough filler is present, which explains why I nearly folded a sidewall in my test today. Goodyear won't let on, but I also suspect there isn't much turn-up going on in there, either.

The whole tire flexes and skips, as a result. The shoulders are moving far too independently of one another. These are absolutely unacceptable when pushed sideways through ridges and ruts. It's like a sling-shot.

The sidewalls also flex more than I'd like when braking, and that was happening when they were first mounted, when braking should have been more about slip and less about sidewall stress.

On to the tread design issues.

The worst effect of the tread design itself is an almost complete lack of self-centering. I'd need to increase toe-in more than I'd like to alleviate the issue. That's only an annoyance on the road, and simply a bit more of a workout off pavement. It's annoying, and requires more hand movement, but not a deal breaker.

The tread design also causes skipping when passing through potholes and over things such as railroad tracks. That's only an annoyance around town, but on long stages off pavement it could be an issue.

Beyond that, they make funny flapping noises when coming to a stop on paved roads, and are fairly noisy. I don't care about that stuff, though. This vehicle is incredibly loud to begin with.

I don't have a problem with the tread design, overall. It's one of the better tires in mud, and certainly a new idea. I'd like to have seen them pull that nearly solid circumferential band a little closer to center, though, so I could mount the tires the other way around.

As designed, the lugs on that end of the section are too isolated to be of use in corners.

Cheers,

Kennith

So... you ended up with the MTR not the all terrain adventure that you pictured that PM said are great on his LR4, Right?

Just reviewed thread, man those BFG MT look horrific. Had 2 set of them, but I think I beat them up before they could rot.

I do love the AT though. I have a set of AT that have been on my F350 for 9 years, obviously low mileage, but never covered from sun and get beat by sun at 7000'. They do not show any sign of rot. Had 3000 lb on them until recently. Likely completely different rubber though.
