Most folk (across all platforms) buy rims for looks. Some will argue that if you go wider you need rims, but if you're only going to 33" it'll be ok. Yes, the tire will 'balloon' a little bit but not so much you can't tune it with tire pressure. For a 35" you should, however, go wider.
A benefit with a narrow rim is the tire will be less likely to lose a bead when aired down (I'm talking if you go down to 10-12psi) If you stay above 15/18psi its usually not a concern.
Big brake kits is not a compelling reason for the Frontier has space between the wheel & caliper to go larger. Also the stock brakes do pretty well. Add some aggressive pads & rotors and that should satisfy 80-90% out there.
For strength, unless you're going to Rally, Race or Beadlock rims the stock alloys are plenty good. Steelies weigh more and the argument that you can repair a steel rim on the trail is a stretch... yes, if you know what you're doing, have proper tools... it can be done. But few have the tools & know-how. And if you're going hard enough that you can/will bend a steelie or crack an alloy, you're going pretty hard and should probably be carrying 2 or more spares...
I'm running stock 16 aluminum SV rims on my 2016 CCLWB with a Camper, tires are BFG KO2. Why does it seam like everyone is running out and buying rims?
Does a larger rim save weight? Enhance or compromise ride. Any thoughts or articles are appreciated.
