Default Wheel Width Effect on Tires

Hi all,

Almost ready to order wheels for my 4dr Rubicon and I will probably be getting the Crager Soft 8's, but I'm curious about wheel width. What is the effect on the tire between the 8.0, 8.5, and on up while running a 35X12.5? I understand a narrower rim will allow lower air pressures while reducing the chance of the tire losing its bead, is that the only reason to go with a narrower rim?

Thanks!

-Derek

A narrower rim also makes it harder to damage the rim from rocks and such. I used to destroy rims constantly with 35x12.50's on 10" rims. The tires do look bigger/widder with the 10" rim though.

You also have to keep in mind not to go too narrow. This can cause the tire to "stick out" in the center and lead to premature center tread wear. If this is too extreme, lowering the air pressure to compensate will not be enough.

And, turning while aired down results in a displaced bead. So, don't get too narrow of a rim.

I know this much... When i upgrade my wheels, I am going with a big offset to allow the face of the wheel to be recessed more. My stock Rubicon wheels are so rock rashed now, It's sad.

I'm no expert, but I'm pretty sure you aren't supposed to put R16 tires on a 15" rim.

His sig says 15" so I'd guess it was a typo.

Can't beat the look of a wide, deep rim.
