Opinions: 15x9" or 17x8.5" Beadlock wheels (for 35s)

I have 15x9 4" BS trail ready beadlocks. I sent one wheel to MrBlaine to fit the 16" brakes behind it, and I know he had to do some work to make everything fit with the wheel. He had the holes on the knuckle slotted slightly and the rotors machined down some. I ordered an extra set of front rotors in case I ever need them.

I have to look into more, but I suspect the 4” will put my tire closer to the SL than I prefer.

I suspect you got a comment telling you what to do without taking your specific wishes and independent experience into consideration?

I’m running a 15x10 (3.5” of bs) with his 16” kit it barely clears the caliper but it does clear.

I don’t know if the work he did for me (mating the brakes to the manual hubs) involves the same work he did for you, but this is good info that I’ll ask him about.

Are you running a swayloc with your backspacing? The SL is the biggest reason I’m leaning away from 4” of bs. I’d prefer 3.75” but TR doesn’t offer that option.

In my case, a 12.5x35 on 3.75" backspacing rubbed the SwayLoc a bit. My current same size tire on 4" backspacing rubs the SwayLoc a tiny bit more. Knowing that higher backspacing improves the steering and handling a little bit along with all the other little things I've done that improve the steering and handling, I'll keep the minor rubbing.

I'm not currently running the swayloc. I may go that direction at some point.

I think I'm almost over hating you for that job.
 
17x7.5" with 35s and internal beadlocks seems like a very nice setup, so far.

Sir, the road goes that way 😂 😂

I still have more then enough clearance away from the my Currie arms and frame for my 35x12.50 tires with 4" of backspacing. To me, 4" is ideal for 35's and commonly installed suspension lifts.
