Serious Tire Question....

[Hank]

I'll sound like an ass.

Bull Shit. Anyone running greater than a 32" tire and not breaking shit is not really wheeling. I broke my stock rear axle within days of installing 33's. I've broken 6-CV joints, 4 or them were HD CV's. And, I'm not the only one - everyone who drives off-raod encounters this breakage at some point.

The stock axles are junk. Actually, they are a piece of shit and a waste of time to even make. Crappy metal, crappy design, and their just plainly too small for a 5,000lb truck.

Top that off with your 10-spline POS diff. It too is junk. By design, it's a weak POS. Same with a 24-spline diff found in trucks up to 2000.

You say you go "wheeling", but I call Bull Shit. You drive a Street Queen and you know it.

As for the tires, they are good. The people I've seen using them are having better luck running them backward. I feel the price is a little steep for that tire, but if it give you that warm fuzzy, go for it. Just remember, it will bust your stock axles or grenade your stock diffs off-road. I'd also look at the Nittos in an 18" wheel. The Nitto's are good as well and wear nicely, but I've not been too impressed with their performance off-road.

Get the Creppy Crawlers.

Damn. A lot of interesting thoughts/words on the subject.

nfrey, you are an engineer as I am. Therefore, you know in manufacturing you ALWAYS try to reduce cost of manufacturing. Hence, why there aren't 1 ton axles under a stock discovery. I'll admit, Rover seems to come stock with a lot more HD stuff than other vehicle makers. Ever take a close look at a mildly built jeep? Stock flimsy control arms, flimsy stock steering components, and terribly small axles with unit bearings in the front with C-clip in the back.

Now, everything depends on terrain. A stock drivetrain with open/open and 35s in the mud is gonna last a lot longer than a locked drivetrain on 32s on the rocks. Wonder why people from the east coast break so much at Moab? Too much traction. For all engineers out there, you can look at the shear stress on an axle that has torque coming in, and resistance at the other end. The shear stress can start to climb.

I don't give a damn what anyone says, the stock rover axles are NOT strong and never will be. It has a great housing with a semi-kingpin outers but the R&P are weak, carrier, and shafts. I've busted salisbury shafts on my 109 with 31s ON THE STREET.

Driving style. All the guys that hammer down all the time, ever wonder why their shit is always broken?? Yep! Pretty self explanatory.

So the DII 18's will not fit a DI? That blows my whole plan all to hell.

Great Thread!

I can't say much about busting axles, as I mainly only encounter mud and water. But, like SCSL said, I find myself doing more of the Green-Laning type of off-roading, besides the fact that there isn't much to crawl over in South FLA.

About the tires, I can testify to the fact that they SUCK in the mud. I've mainly seen those tires on Rock Crawlers on the Left Coast.

Oh shucks!!!

You obviously don't want to listen to any GOOD advice so.... Go redrill those 18's to fit your D1.

nfrey2: you are a moron and I can't wait until you bust a CV without spares.

Even though I'm one of the younger people on this board I'll act like the adult and refrain from the name calling.

First off to make this clear I am not trying to argue that a smaller axle is just as strong as a larger. Nor am I going to argue that the carriers could be beefier.

I am merely stating that given mine, and fellow LR owners in my area, experience the factory axles are sufficient for the larger tire size and the type of terrain we do.

I say terrain becuase it is that that defines the abuse the drivetrain sees. Like 01001010 said, in Florida all we encounter is sand, mud, and clay. Traction is not existant. There is only one place I know of in FL that has rocks and what could be considered a rock garden, but it was closed before I did any mods to my rover. But I guess everywhere else in NA the this doesnt apply, so Im safe on my little penisula, from busted drivetrains, just not hurricanes.

So with the terrain we see here I feel that the drivetrain is sufficient. I also attribute it to driving technique as well. But as Hank stated a I drive a "street queen" and I dont really wheel. Or maybe its just that I'm not a reckless hillbilly like most people in FL and use better judgement on line selection and read terrain better than most so that I still make it up the same obstacle, without pegging the motor WFO and potentially creating a sitution where a sudden stop in wheel rotation could send a shock through my drivertrain.

Now to broaden my experience on the topic, I will be in Tellico for New Years and spending a couple of days on the trails. And since this is a lot of money for me to go on trip like this I will be bringing spares b/c it would be a shame for me to shear an axle or bust a carrier and spoil my weak

So we'll see... and you'll be able to call me all the names you want, for those who feel the need.

Everybody else cheers, b/c its Thursday and its college night at my local pub

How about me drilling my foot up your ass little ben?

I asked a question, and got plenty of answers. Thanks again for the positive responses.

Wow, such much love, joy and friendlynes in this thread I really don't know what to do with myself.

Well it's no bad thing them not fitting, 18's are hardly the wheel for off roading, too much metal.

Besides what was the aim of use for the Discovery with those wheels?

Personally I run 33.11.50R15's I have no lift but upgraded shocks and springs and slightly trimmed wheel arches.

I know of some people who run 35.10.50R16's, slightly narrower but taller. They don't really need any other mods over running 33's.

I like wide wheels, but personally I won't go any wider than 11.50 not in 15 or 16 inch rim size, this means you can still run a 8j wheel any wider and you really need a 10j wheel. And this will limited suspension travel and steering lock.

If it's for street use then there are 18" alloys available, but I'd run a street biased tyre or alterain. But 265-285 would probably be as wide as I'd go on such a vehicle.

Talking about benefit of running biggers rims, in the last couple of years American auto manufacturers have gone to 17" rims to make way for larger brakes. Obviously, this is a benefit.

Rims can be made of extremely lightweight material (duh) and can be quite strong. I do not know any facts right off hand, but a lot of times a giant rim and a smaller tire weighs less than a smaller rim and a bigger tire. This has a lot of benefit in dealing with rotational mass. In the jeep world, when 1 ton ford axles are installed on a jeep, usually H2 hummer rims are used because they are plentiful, strong, and only weigh 22 lbs. Not to mention the H2 rim looks pretty good with a 40" tire.

No offense to anyone, but didn't the guy's question get answered like six days ago when he was told that the bolt patterns don't match up? cmon.

Relax ....it's called a "thread"....it could go on ad infinitum.....or as long as we have beer and tech data............

40" tyre, are you serious. Unless that Jeep is super modded 33" seem to be the ultimate size for articulation but that still requires a lift, and 35" with limited travel unless the Jeep has about 2 feet of lift on it.

I've seen 37" swampers, but you can count axle articulation as zero.

Huh?

Here is my buddy's Jeep on 42's. The articulation sucks, huh.....

Nice pic, but are your really trying to convince me its anywhere near stock.

Can you fit 35's ona stock Heep?
