I'm on search overload. I've read many places that specific tires have a spec that they can fit specific wheel widths. Where can i find that spec? what does it look like?

I have 16x8" rims, and I'd like to put 315/75 16r on them. More specifically:

Falken Wild Peak A/T
or
Falken Rocky Mountain ATS
or
General Grabber AT2 Studdable (are these good for hot weather also?)

Follow up question--- If I can't fit these, wher can I find some 16x10 wheels that aren't a fortune? I'm spending a bunch on a lot of work right now, and trying to lower some costs.

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.

Are your stockers 245/75 or 265/75? Going from 245/75 to 315/75 will make your speedometer read 13.59% too slow. At 60MPH it will read about 53MPH. Going from 265/75 to 315/75 will make it read 9.35% too slow. At 60MPH it will read about 55MPH. I'm not certain but I assume the odometer takes it's information from the same system....if so, your truck will start to rack up miles on the odo at the corresponding slowed rate. Not necessarily a bad thing...just something to keep in mind. Also, a 315/75 is basically a 35x12.50. Will that tire fit on your truck? I have no idea about the pre-2002 models.
