Small Tire

[Ovrez]

How small of a tire can I get away with using an unshaved 14 bolt?
Have 42" Iroc now and would like to use a 37" tire, but am I going to be dragging the 14 bolt?
4x4 in the PNW

If you ain't dragging your 14 bolt, you're not doing it right.
Really dig your rig man

^^No truer word spoken^^
Nice jeep, those bluetooth front hubs?

If you want 37's, and that is truly unshaved, get under there with a grinder and grind off the bottom lip, should make up little less than half the difference of clearance loss between tires.

runnin anything bigger than a 31 is pussy

My buddy runs 37 km2s (measure 35" in reality) and his is shaved, but it's never been an issue. True 37s, you'll be fine.

People wheeled fullsize trucks on 31s and 33s and 35s with those axles back in the day. You'll be fine on pretty much any tire if you grow a pair

Why such a huge step down? Competing in a class limits at 37”?

Not competing, I have to drive to the trails and the 42" iroc is not very fun at 55-60mph so going with a smaller tire

 

[YotaAtieToo]

Why not go with a 39-40" radial? about the same actual diameter but will drive mu h better.

 

[BigWheel]

Yeah, bias are not the fun on road. Regarding your actual question, grind the pumpkin. I have the 2nd gen 14b and by buddy ground all the lower ribs and lip off for me. I still bang it off shit, but I'm not getting hung up. Basically it's a d70u now

If your running a 42 Iroc you are already running a 38.

As others said, grind that lip so it’s smooth on the bottom, that gives you another 3/4” of clearance, and run it.

So I got new wheels and tires went with rolling big power beadlocks and Cooper stt pro 37x13.5x17r.
Runs 65 down the hiway fine , have not done any balancing at all. The Iroks 42x14x17 bias were terrible to drive on the road at anything over 25.
I mounted the beadlocks with no tires first as I wanted to see how much runout there might be, the worse 1 was .020 on the machined surface.
Way easier to get into the jeep now also.

How close to 37 do they measure?

How close to 37 do they measure?

Mine were 36-1/2" tall at street pressure mounted on 17 x 9 beadlock wheels

if you have one a portaband works great

Ya it does. First shave kit I did I cut/ground the bottom off with a 4.5" angle grinder and it took FOREVER. Second one I did a friend suggested a portaband and it felt like cheating.

 

[rockyota83]

ive shaved 3 or 4 and the portaband is my go to in the shop
