18" tramlines

[nbturbo]

I bought a set of wheels and tyres secondhand for my Beetle-they had only done about 4,000 kms.They were 17x8 with Kuhmo Ecsta 235.45.17 tyres.They came from an XR6 Ford Falcon, so when I needed some new tyres on my Ford ute,decided to put the 17's on until I needed them for my Beetle.These would have to be the worst tyres on the market for tramlining-the thing was all over the road.I couldn't handle it for very long,so bought another set and stored the 17's.Next trick was my Mitsubishi Van was in need of some new tyres,so bolted the 17's on that for a try out-was even worse on this car to the point of being dangerous-must be a lot lighter on the front end-it would pull the wheel out of my hand if I found any ridges in the road.Stored the wheels again and bought a new set of wheels and tyres for my Beetle-will use the Kuhmo's on my tandem trailer-about all the Kuhmo's are good for.They still have only done about 8,000kms-no wonder the bloke did me a good deal in the first place.It must have something to do with the shoulder on the tyre-I put some Sava Intensa's on my ute which look identical at the shoulder-but tramlining ceased immediately.I also put a set on my NB Beetle in 17's and no tramlining with it either.
