For some setups the "standard" 1/8th of an inch toe in might not work. I've seen instructions telling to use small amount of toe out to get proper ride quality.

The 35x12.5 on a 20 inch wheel are basically just asking for trouble... Huge tire with low sidewall will be very tricky to dial in.

The thing with low profile tires and wranglers is, that the double straight axle setup really is not something one would go by if handling is of importance. Especially a straight axle up front plain and simple sucks. Add high lift, draglink and track bar not beign fully aligned, and the low profile tires no longer are an advantage.

The vid I saw the instruction on toe out was one of the light brite nation product plugs. That couple is a handful, but I still kinda like to watch their stuff 馃槀

I'll try and find the exact episode and I'll drop the link here.

Edit: here you go:

They are the ones promoting bad wheeling practices which in turn gets our trails shut down. The environmentalists use these videos to get trails shut down and is happening in Colorado and Arizona. It's a shame people keep supporting these two.
Environmentalist will dig up shit everywhere. Not sure how Lite Brite's wheeling is any different from any other channels I follow. I think they just are an easy target for reasons I better not get into, not in this thread anyway.

I get your point on the not being a handling vehicle, but the same logic still applies, less sidewall will create a harsher ride, but also more precise in terms of less sidewall flex. With my 20 x 35 set up I still have 7 1/2" of sidewall. This isn't my problem. I wish I could figure out how to attach the video I took yesterday of the wheel reacting to me rotating the tie rod.....Its either this or the steering box. I was hoping to find others that had narrowed down their steering issues to the same issue. I would appreciate the video if you can find it
I'm still gonna say the low(ish) profile of the tires does not help. To get the load rating it has, the sidewall will need to be pretty stiff. That will, of course, relay the road "feel" much better to the steering wheel, but only if the steering components are engineered for good handling. Wranglers' are not...

Consider this: even the F1 engineers were really up to a challenge when for this season they went from 13" ro 18" wheels. The high profile tire used to be a major componen of the suspension, and taking that away ment a lot of re-engineering.

Suspension on Wranglers is not designed for low profile tires. I do realize 35x12.5 on a 20 is "only" about 315/60R20 in euro size, but it is relatively low profile for a Wrangler, so whatever it is that is off in your setup, will be magnified by the wheel/tire combo.

Edit: I gotta say I like the look of 20" wheels on a Wrangler, if the tire is big enough like yours 馃憤

Comparison should be made with the "string method" from joint center to joint center disregarding any bends in the connecting elements. These lines for drag link and track bar should be as aligned as possible. In extreme cases a bar that has a bend in it will flex more than a straight one, but I have not heard this being an issue in Jeeps. Might have an effect if the bar is made from chinesium.
