If you are looking for it on your tire I don't think it's on there. You can find that info on the tire manufacturer's website.
According to their sites the Wildpeak is safe for 8-11" wheels. Strangely enough I couldn't find anything about the Rocky Mtn on their site but I would think it would be the same. The Grabber is listed as safe for 8-10" wheels. I wouldn't have thought you could put a 315 on an 8" rim but I guess the big sidewall lets it pull in enough to fit. It's gonna have the stuffed, marshmellow look.....nothing wrong with that, just that some folks like it and some don't.
Thank you :smileup:
