Is it possible to get good sticky tires that don't tramline?

2,500 posts, a sweet-ass Saleen and you don't know what tramlining is?!?!?!?!?
J/K
Tramlining is when your tires grip any little rut or channel in the road and want to follow it. It really pisses me off. Sometimes it happens so bad that the steering wheel jerks pretty hard. I'm just waiting for the day when a cop is behind me when it happens and pulls me over for DUI.

Well I am not sure if this is a valid term or one that you have conjured up. If you could validify the term that would be great....
The following link properly describes the affect of wheel/tire drift based upon suspension geometry (in relation to caster/camber). Personally, I have not seen the effects of this due to sticky tires, rather the width of the tire - the wider the tire, the more drift or pull.

lol, yeah I just pulled tramline out of my ass cuz it sounded good.
Nah, I got it off of corner carvers. I'd never heard the term myself until I read a post over there. If it's not correct, don't blame me.

Considering the source is quite reputable, I would agree the existance of the term. I did a search for it but could not find anything. Could you point me to the link?

I've always know that as "hunting", and I believe it's primariy due to running BIAS ply (vs. Radial) sticky tires. I feel this a lot with my Bias ply 15" goodyear racing slicks...

Never heard of bias ply. How do you find out if your tires are bias ply or radial? Does this mean that bias ply tires tramline more than radial tires?

I used to have Yokohama A520 and those tires wanted to stick onto cracks in the road especially on the freeways when they go from asphalt to concrete. Thats the main reason I would never get those tires again and they have terrible tread wear.

I've got Kuhmo Ecsta 245/45's right now, and other than the fact that they tramline like a bitch, I love 'em. They grip as well as, if not better, than my Pirelli's and were only $100 each! Haven't driven them in the rain yet though, so I don't know how they are for wet traction.
But I think rr's got a point about the size of the tire being a factor, because I don't remember tramlining at all before I got the ROH rims and went to 245 tires.

My R's 18x9.5" wheels had BfG KD's in the rear, which I replaced with the Kuhmo Ecsta's all around. 275/35zr18 and both sets of tires seemed to follow every crack in the road. The front seems to do it more often since I took the 245's off and put on the 275's. The rear was really pulling from side to side until I had a 4 wheel alignment done.
The 245/45zr17 tires on the 01's 17x8 inch wheels don't seem to tramline at all. ![[burnout]](graemlins/burnout.gif)

You absolutely have radial tires on your car. Bias Ply haven't been used wide spread on passenger cars for 20 or so years

"Hunting" is when you front end doesn't stay planted around corners it hops around a bit.
Tramline or whatver you call it i think is neccesary if you have sticky sticky tires. I think sticky tires grip really well for smooth tracks/ or even some road surfaces but when you hit rough road the tires are so good and sticky that they follow the cracks in the road. (Just a guess). I have never heard of anyone having this problem on street tires???? Like Kuhmos or Yokohamas........My guess is that it's not the tires...

Funny, I thought the rest of civilization calls that bump-steer. Review "cobra427's" term of "hunting", which is in fact valid.
Common Definitions
Not one of the best sources, but informative....

So, this (tramlining or hunting) only happens with race tires and when they are hot. Then why is it that when coming home from work somethimes at, let's say 3 or 4 am the tires tend to pull (without road crown being a factor). Obiously at this time of the morning, my tires are not getting hot, at least not as hot as race tires on a race track during the middle of the day, and I am using stock tires on my SS(Goodyear Eagle F1 - 275-40-17). Whereas on my Mustang with 245-40-17 tires, same aspect ratio and same rim diameter, there is less hunting even on the same roads. I have also seen the same effect with my truck (275-70-17's), comapred to another truck I owned with 245-70-16, the pull was not as predominant. Based on these two factors, heat nor race tires have an effect on the fact that my car is still pulling towards the grooves or large cracks in the road.
Once again, great article and quite informative:
