As I stated on another thread, I have had to replace the traction tires on my VL Niagara 6013 that the right side had shredded. I had a heck of a time getting them off with the Loctite on the threads but managed to do so without boogering up the threads to much. I did replace the traction tires with MTH traction tires and after a week of running it no ill affects, pulling 10 MTH 18inch Madison Passenger cars. I used the DE 0000031 size and so far is going strong. I did order some of the CCII traction tires last week from Lionel with their 50% discount. So when these go I'll give those a try.
For those of you inyerested here is the MTH traction tire chart.
