Default Steering concern on my 2004 coupe

I have only had my car for a few months, but I have noticed that when I drive on a road that has some unevenness or small ruts that my car wants to follow them. The car has 59,000 miles and the tires are about 70%. On the Interstate where the road is smooth , it does fine and does not pull either way or wander. Any thoughts?
Thanks

That's what happens when you have wide tires. They want to follow the groves in the road. What size tires do you have?

It's a condition called tramlining and some tires are really prone to this while others not so much. The Hankook Venus V12s I run on my car do not exhibit this tendency, but the Goodyear OEM runflats I had sure did.

Here's an explanation of what it's all about.

Interesting... my newish Goodyear F1 Super car tires tram line also. Nothing bad, and mostly just one strip of the highway to work, but my other vehicles never have (nor on the same strip).

I agree with the others. The wider the tires, the more you will tramline. Runflats are the worst.
You need a set of these babies if you want to eliminate tramlining altogether..............LOL.

If you've only had your car a while, do you know when the 'alignment' was last checked, and set properly? Is your steering wheel centered properly?

If not, you might also do a full car alignment, to make sure that's correct. Find a shop, used to doing Corvette, and sports cars; who also knows how to lift Corvette properly without damaging it.

Don't assume they know, ask!

good luck,
Don

New different brand of tires and an alignment took care of that problem on my car also. Continental DW's are what I went with but there are other brands that are just as good if not better.

I have experienced a similar situation while driving here ( in Northern Indiana) because many of the rural road are used by Amish buggies and the roads tend to become grooved due to the narrower track of the buggy wheels. I had just put on new "summer tires" and did research and discovered the same thing as others posted. (bought my tires from Tire Rack - they have great technical articles).

Really? Mine definitely tramline quite a bit (they're the 2nd gen k120 model) but they're nowhere near as bad as the Bridgestone Potenza S-03's that I had years ago when i had an e36 M3 (and those were only 225s in front...)
