There is a thread on the TMCC/Legacy board and traction tires are discussed.
One of my SS PRR Centipedes wobbles. I believe it is caused by the traction tires.
What is the new number for the new 'better' Lionel tires?
Alternatively, how do I order the better MTH tires? Number? I've no experience ordering from MTH. I went to thier website and it is not too intuitive, to me at least.
