Hi everyone, when my factory Grabbers wear out I am looking at the following setup. Wondering if anyone has experience with these parts together:

BFG K03 (K02 would be the same) 35 x 12.5" tires on the factory 18" Tremor wheels

I know the factory wheels are 7.5" wide I think and the offset is +34

I already have the Auto spring 2.5" front level installed

Cannot do wheel spacers - illegal so do not suggest please

I think its ok for not rubbing, and the 34+ offset along with the 12.5" wide tires will give a bit more poke (did some comparisons on the tiresize.com site)

Wondering especially about the 7.5" factory wheels with the 12.5" Ko3 on them. I imagine it will have a large amount of bubble out from the rim. Is that ok? have others done this? or is that too much width for those wheels to handle?

Backup plan could be the metric version that comes in at 12" I think, and another 34.8" tall option is 11.5" width I believe in metric...

Future-future plans might be some Fuel Rebel 18" +20 offset wheels.... Thanks all!

What auto spring did you go with? Considering a similar setup. I was looking at 2.5 Rough Country level which would still give me about an inch of rake which suits me. I haul some weight occasionally so a little rake is fine. KO3’s looking appealing.
Thanks
