I went with one + size over on my Goodyear F1 tires and the torque steer went away. But then I went 10,000 miles between tire rotations and as soon as the rear tires went on the front, the torque steer was back. The tramlining effect has always been an issue, but only with ultra-high performance summer tires. AKA, stiff and low sidewalls, wide tread contact patch.
I do not have any torque steer problems with the 16" Dunlop studless snow tires, as long as the temperature is 50F or colder. 90% of the winter, when the temp is FAR below freezing, the car handles almost as good as the summer tires. Of course not in the area of extreme traction, but response and tightness of the handling is right up there. Once the temps warm up, the tires become scary and of course I have switched to the Goodyears by then...
So my point is that tires are the big issue here, not necessarily the engineering of the car. I can see where there is no way to completely test all tires and wear patterns, widths, wheel offsets, etc. So I don't really blame anybody for the torque steer, it's just another variable that popped up after it was probably too late.
Another example is my Silverado. I went to Sears last week and got a tire that the sales guy highly recommended. But as soon as I left the shop and hit the freeway, I knew there was a MAJOR problem. The back end was soooo loose, I feared for my safety. The vehicle was almost impossible to keep pointed straight and it felt like the rear end was on crisco. Went back and they admitted that the manufacturer had told them 1 in 10 trucks will have this problem. We switched out the tires for another similar style and all was well!! Turns out the first tires I had used kevlar instead of steel belts. I'm thinking they were just way too soft for my truck's light rear-end. Most likely a Tahoe would have been fine...
