Stock 18" Tires and Tramlining on Grooved Highways
 
One of the highways I drive on during my commute has a grooved concrete surface (to deal with rain water I believe). Basically it looks like corduroy cement for those that have never seen it before. Over the years, I've own two sets of tires that were prone to tram lining on this highway. Now that I bought the Jeep, I unfortunately own a third set :(

This makes the Jeep feel very unstable and uncomfortable. I'm going to have to buy new tires ASAP.

Has anyone else noticed this same issue? Does anyone know of good tires that don't have this issue?

The Tramlining could possibly be from just the fact that you have somewhat of a wide tire. Sounds a little silly but I promise wide tires are more prone to this.

Norcal what size rims do you have? Factory 18" and 20" rims comes with 265's while the 17" rim comes with 245's.

I'm pretty sure it's actually a tread design issue. I've had one car with 225's all the way around that had the issue. My other car was a staggered 245+275 setup that sucked. As the tires wore, the tramlining was less apparent.

Factory 18" that come with the 4x4 Limited.

What tires do you currently have on your GC that tramline? This could help out others.

EDIT: disregard, I didn't notice it said stock tires.

Wide tires make tram lining worse. If any of you have driven a corvette or other car with ultra wide performance tires on the highway you know how bad this effect can be. They will follow the truck grooves in the highway pavement.

The grooves the OP is describing run perpendicular to the tire tread. Don't know if this is the same effect but wide tires do make a difference.

Check your wheel alignment negative toe can cause this also

For clarification, I'm not talking about truck grooves. And the grooves I am talking about run PARALLEL to the tire tread.

Maybe. But everything else I'm reading points to tread design.

I think those kinds of roadways are rare for most of us. Since tread design is the same for sizes across the tire model, if you have had good luck with a brand/tire model in the past you should have similar performance in a tire the wk2 size. The wk2 steering is more truck like/looser than many cars, however.

The stock Goodyear Fortera didn't have a problem on my wife's Outlook (18" version of the same tread design as the 17" wheels on the WK2 come with). Those tires were pretty awful on ice when the tread depth reached 50% but we never noticed the grooves in the concrete surface from when they were new till they were worn out. Then we put on a new set of Michelin LTX M/S2 and noticed it tram line quite a bit. My truck has Nitto Terra Grapplers and it does the same thing now too. The common theme with the tires we used to have (bigger tread blocks on the shoulders without as much siping) didn't crawl/tram line on the grooves as much or at all as the new tires with smaller tread blocks and lots of siping. It's a trade off we're living with since the snow/ice performance is much better.

I'd suggest looking for a tire with larger tread blocks/less siping. We had a set of Bridgestone Potenza G009 that were excellent on the same stretch of road and on ice/snow so a good balance can be found.

We have a stretch of grooved freeway as well. I have not noticed any tramlining on my stock 18" Latitudes. I have noticed this on other tires.

I have this EXACT SAME problem with my brand new 2012 GC Limited. 18" wheels, stock Michelin Latitude tires. It is MADDENING. This vehicle was picked up only 4 days ago; the last thing I want to do is pay my own money for new tires.

May take it in to have the alignment checked but, again, this is right from the factory and it exhibited this the day I drove it off the lot.
