Re: What are these 20" wheels good for...Absolutely Nothing

Yes, I've also had good results with the Forteras...at 30K miles and still 1/3-1/2 of the tread left all around. But Nitto 421Q's are next for me, probably late summer...

Same here. I want to get out of the Forterras but need to wait until they wear out (which will be too long).

Re: What are these 20" wheels good for...Absolutely Nothing

I think what would have been good is if Jeep wants to off the 20" option for mostly the "look" than build a tad more space into the wheel well so if someone wants to go a size bigger to gain back sidewall they don't have to do further modification to not worry about rubbing.

you can go a size bigger with no modification. many, many here have done it.

Yeah I know, but I haven't seen the larger size whether it be the 275/55 or the 285/50 really tested in off-road/on-road hazard situations. So I don't know if they will rub when truly flexed without additional mod.

the difference in an 18" and 20" wheel on a stock Jeep isn't going to make much of a difference. Your Tire OD is going to be about the same, the on road difference is the 20 will ride a bit stiffer and handle better. Off road difference is you can air down the 18 a little more.

I don't understand what the fuss is all about. It's not like swapping from a 20 to an 18 will suddenly allow you to run Hell's revenge in Moab.
Small differences, IMO.

Uh, that's a big 2" and it appears that Jeep thinks so also since they don't even offer ORA with the 20".

If I remember correctly, In the WK years Jeep didn't give the "trail rated" badge to the models that had 18" wheels instead of 17" wheels (Summit/S-Limited). Jeep puts together different package groups and the group with the larger wheels may not include the ORAII. I would be inclined to think you could order it that way though. Im not saying there is NO difference, but that the difference is very small for an otherwise stock vehicle. We are talking 1" of sidewall here. What type of terrain are you tackling that 18s will conquer and 20s are "useless"?

I never really got into the whole "off-road thing"
You implied (by stating 20s are useless) that your local roads were off road quality or you needed something like a farm tractor to negotiate them. Thats the only condition 20s could be considered useless.

There are no public road hazard condition that an OEM 18 saves you from that the OEM 20s won't when both are properly inflated. You are kidding yourself with BS if you think otherwise.

Damage to a 20 inch wheel is more costly to repair, however. So we swap out 20s for 18s in the winter because we can beat the 18s up sliding around without bothering to fix them... or if we want to fix them, spend a bit less money. Some of us swap them out when wheeling for the same reason, some of us don't bother and have fun regardless. As others have said, the differences are not that significant off road on the kind of trails you'd take a WK2 on.

Oh, you can find several examples where jeep won't put a trail rated badge on a vehicle with smaller diameter wheel, only on those with larger wheels. Our lIberty is an example.

ORA is merely the addition of 18s (if 20" is standard on that trim level), skid plates, tow hooks (if not already on the trim level) and a plastic badge on the side of the Jeep in most cases--transfer case difference and QL on lower trims that don't include it already. ORA doesn't get you off-road tires, although they provide the 18" wheels which for off-road with the right tires is certainly a better choice for that activity and they do know that as you state. It's mostly a marketing thing. This is all semantics and subjective preference. You would prefer the 18s; I'm very happy with my 20s. It all works out in the end!

Re: What are these 20" wheels good for...Absolutely Nothing

There's a reason Jeep puts the "Trail Rated" badge on trucks with 18s and not with 20s.

If the tread height is the same, but one has a 2" shorter rim? That's 2" more sidewall height. Sidewall flex. Shock absorbtion. Guess what folks...the TIRES on a 20" rim aren't 2" taller than the tires on an 18" rim. Ground-to-top-of-tread...same overall height, just 2" more of that space is wheel (hard, unforgiving metal) on a 20, than on an 18.

If you offroad? Get the 18s.

If you're using your WK2 on-road like me? The 20s do just fine, if you pay attention and don't drive like a moron. Potholes will dent ANY rim if you blaze in at 100mph. Use some common sense and don't hide behind a Jeep badge in the name of "doing anything".

I have a Jeep I use off-road. It's my 92 YJ with 2" lift and 31x10.50-15 tires. THAT is a sidewall. And if I bounce it off a tree? Don't care. It's old. Paid for. And just adds character. I drive the YJ like a moron. I drive the WK2...like a luxury car.

If I wanted to drive my WK2 like an offroad mud-machine...I would have optioned it differently. It isn't Jeep's fault one way or the other - they offer the packages...you just have to pay attention when you order your vehicle.

Re: What are these 20" wheels good for...Absolutely Nothing

I didn't order my jeep wrong, it's what was available when I was in a position to acquire it. The dealers simply couldn't locate what I wanted when I needed it. It's not the biggest deal since I would've changed the tires anyway to something more AT and the rims (18" stock) can be had for around $400 from a takeoff.

The whole point is that the 20" in every situation whether it's an on-road hazard (potholes, curb rash) or off-road hold no advantage other than looks and slightly improved handling which I don't really notice. In all those situations you'd be better served with 18". Obviously the 20" aren't useless and depending on your driving they would be fine for many. My thread title is an expression. You can't always avoid road hazards so if you have to go thru a pot hole or hit a curb because of another driver or whatever your better off in the 18". My expression of a Jeep is that I shouldn't worry as much about hazards compared to other vehicles on the road, but with the 20" I don't get that feeling.
