wheels for spectrum passenger cars

[blackz28]

ok i have a spectrum passenger union pacific car set & they track really really crappy & i wanna replace the wheels sooo whats the best out there ??

I use P2K 36" wheels, in all my plastic passenger trucks. I do put metal axles, (generally Intermountains), into the ones that have metal sideframes.

Would definitely recommend Intermountain 36" wheel sets. But have a look at Reboxx as they make them w/ axle lengths to exactly fit the trucks your cars:

Also get the Reboxx Exact Socket Hand Tool to ream out the axle holes to greatly improve the rolling!
