Hello guys I found this post on the charger forums written up by "Ohthatguy" with some great info on actual tire sizes. I am copy+pasting the info and again this does not belong to me!

Sticky maybe?

Goodyear 275's 10.5" wide
Vred "315's" 10.9" wide (smaller than 295 but possibly would measure bigger on a wheel wider than 10"?)
Nitto Invo 315's 12.4"
Goodyear/ BF Goodrich 285's 11.75" (approx)
Michelin Super Sport 295's 12.6"+ (massive width for a "295")
Toyo Proxes ST 315's 12.1"
Yokohama Advans 295 12.2"
Dunlop 315's 12.25" (approx)
Bridgestone Potenza 305's 12.32" (when mounted on an 11" wide wheel)
Continental Extreme Contact 315/35/20 (approx. 12.6" - whatever the actual width of this Conti is, it seems to just about max out the stock wheel well down to the mm while avoiding poke or rubbing on a 10" wheel)
Pirelli PZero 305's 12.6"+ (approx. , Somewhere around this threshold in width you probably run out of wheel well on a stock ride height LX without having suspension/ interior side contact or poking beyond flush with the fender?)
Michelin Pilot PS2 295's 12.6" (approx)
Pirelli PZero 315's 12.9+"
Yokahama Advan Sports 305's 12.9" (approx)
Michelin Pilot PS2 305's 13" (on a 11.5" wide 19" CCW wheel)
Goodyear Eagle F1 GS-D3 305's 13.1" (unmounted)
BF Goodrich KD's 315's 13" (approx)
Toyo Proxes R888 315's 13.0"
Goodyear Eagle F1 GS-D3 315's 13.5" (approx)
Michelin Super Sport 315's 13.5"+ (LX's at stock height & proper offset will still have interior side contact and considerable excessive poke with this width of tire)

Remember your contact patch with the road won't be much wider than your wheel. Don't overbuy your tire size! I don't know how they measure anything 13" wide on 9.5-10" wheels, won't happen. And yes about anything more than 12.25" wide will begin to give you fits with your offset/rub. Talk with Biz, he knows the sizes well.

I don't know where he got this data from, but it is significantly different, almost all larger numbers, than TireRack, where tread width is actually measured instead of using manufactures data.

hmm... he said that it was from different sources but none were verified. no links attached
