I need some help guys. Building a widening trailer and, I want to find a source for these type, size, scale wheel and tires.

1/25th Scale 215 75 R17.5 and 10 stud wheels to go with them.

Approximate scale size, I think is 32 mm O.D. ?.

I will even go to offshore sites for them.

So any help you can give will be appreciated
