I have a 51 3100 with stock rims and stock suspension. The rims are 16", 6 lug with 5.5" lug spacing. I don't know the width of the rim - I would have to remove the tire from the rim to measure and I can't do that for a while. I would like to get another stock rim to replace one of mine (it's a little wonky). Are there different size rims or is there a standard size? If I can't find a stock rim what would be the rim and tire size can I look for in a junkyard?
I think I also want to replace my current tires with radials next year. Is there an optimal size tire that works well with the current stock rims?
