Not sure if anyone has a durometer hardness tester?
I don’t think this is a tire hardness problem Dave, what it looks like is there’s not much tire selection out there to accommodate the issue on Fast Track, ……what’s happening in Sean’s case when he switches to MTH tires, the tire sits down in a valley, and given the location of the tires ( front axle ) and the profile of the rail head, his engine ain’t riding on the rubber tire at all,…….ok if he’s on level track, but it’s exasperating when he approaches his grade, …..and if there’s any curves in the grade ( which he has ) the problem gets worse cause now she’s locked on the defined metal lip, and the rubber tire again, ain’t even touching the rail head,….he will have to either find that “perfect tire” or mod the engine to accept the MTH tires …..
