LOST JEEPS :: View topic - Tire Sizes - What does more width give you?

I run 245/70/16 on a 16x7 wheel, so the width barely changed (if it even did) from stock. Some guys here run 245/75's on 8" width wheels but I've read that it can be bad to stretch the tire.

Width does give you better traction in some circumstances, but the 7" is great for DDing and hasn't caused issues with the mild wheeling I've done.

IMO the more side wall the better. And overall tire height being equal a narrower tire is generally better. (Except in situations where floatation is desired)
I really like this article, and it explained a lot to me.http://www.expeditionswest.com/research/white_papers/tire_selection_rev1.html

I'm looking to get new tires after I lift. I know a bigger diameter will give you a bit of lift and lower your drive ratio, but what effect does width have? I currently have 225/75/16 and was looking to go to a little bit bigger diameter (30"ish), but I'm still undecided on the width.

245-75-16 weighs approx 38 lbs
265-70-16 weighs 41 lb
both are close in height
3 lb total weight per tire, 12 lb total on the KJ/KK
I carry 5 times that in spare parts at least in mine so whats another 12 lb

Most of us choose to go for 245/75-16s. They're about 31" tall. Width gives the wider footprint allowing the tire to "float" more on sand and snow. It also gives more traction(except some circumstances like rain, water, ice etc), but that normally means more rolling resistance. I can tell you I'm happy with my 245/75-16 Duratracs. Don't get me wrong I would love bigger, but we're kinda limited lol.

I wonder if 265/70/16 or 265/65/17 (30.6'' tire but 20mm wider than 245.) would fit on stock rims without generating issues like rubbing on internal parts at full lock, of course with a good lift ~3'' Rubbing on the pinch well is not a problem.

Lol true... We'll not worry about 12lbs unsprung weight versus sprung but 3 lbs isn't A LOT in that example.
