Which link?
I haven't aired them down that far. I don't do any intense wheeling, just the occasional trip to the snow and a dirt road when I can find one.
You probably already have the same steel wheel as a spare. I know I did. I bought 4 of these Terra Grapplers and then found a used but in good shape random 285 for the spare. Maybe I'll regret that someday, maybe not.
Actually I have never checked what I have as a spare so you may be right. Maybe I will check tonight. I think I may get a non-DuraTrac as a spare for now.
Thanks all.
