light weight 36 or 37s

Looking to go from 35 km2s to something a little larger. My km2s weigh 64lbs a piece are there any tires slightly larger that are somewhat close in weight?

Looking for 36 or 37s unless they make a true 35. My tires only measure 33.5

Thanks

IMO, a D30/35 combo is very safe with 33" tires. You can still break it, but it's safe. A 35-37" tire can be wheeled safely but it takes someone with restraint to keep from breaking them. I wheeled mine pretty hard with 35" Krawlers before I broke them............... but I eventually broke them. The way I see 2fst4u driving, they won't last long.

I don't see a big plus to tacking the caps in place. Sure, they eliminate the snap ring from coming loose but in most of my axle joint breaks, I broke the pin off the spider or twisted out an ear. Snap rings were still in place.

I have a d44 rear and d30 front with chromos they have held up well for me. I feel as if my setup will hold up to bigger as long as the tires aren't too heavy. I would love like to find a set of 36 iroks on beadlocks.

At Wellsville over the weekend I broke a front ujoint but I'm pretty sure the cap came out even with full circle clips but I will have to look it over again. If that's the case tacking the caps could have prevented that

This is at the heart of where you are wrong. The weight of tires is not nearly as devestating as the leverage and traction. Most hard breaks I have witnessed have been at idle or slightly above where traction is trying to be gained. Once a tire grabs, that's where things snap. The weight (mass) of the tire will only come into play at higher wheelspeeds which you can't acheive anyway with your 4.0 and 3.73's. I'll say it again, tacking caps is over stated. If your cap sits tight in the ear and the snap ring is in good standing, they will hold. I have never broken a joint where my cap coming loose was the problem.

Having "only" 3.73's makes Johnny's point more important. You are putting higher stresses on a higher gear, not less stress.

Can you run 36-37" tires? Sure. It's not a problem, but you WILL break more.

IMHO, you are wrong. If you upgraded shafts and joints in your turdy, the ring and pinion will be the next to go if you go bigger with tires.

Also, if you go from 35 to 36 tires, you will lose your ass when you do your axles upgrade because you likely won't be happy running 37s with an axle that could handle 38s or 39s. Do it right the first time.

Unless you plan to make a giant money pit, you need to sit down and figure out what your next step is. Getting to 35s on a stock-ish TJ is pretty easy and can be reasonably reliable. Bumping past that and you'll be blowing parts on a regular basis unless you only use the jeep to cruise or run 2-tracks.

I only have 3.73s so I'm not too concerned with the R&P but definitely understand where your coming from. My axle ugrade won't be for atleast another year I'm just looking at a new set of shoes to get me by until then because mine are getting somewhat worn. Regardless I will need new tires and wheels when I go to one tons because of the 8 lug vs my current 5 lug.

I would get a set of 36's and run what you got until you start breaking shit. Upgrade axles then. However apparentley live in a fantasy world where you don't need a Dana 60 front and a 14 bolt rear to truly enjoy going offroad.

I'm looking for a true 35 or 36 at the moment. If I go with a 37 it will have to measure small and be somewhat light because otherwise I know I will be breaking parts quite often

Tacking caps on stock shafts vs tacking caps on chrome Molly shafts are two different things. With the stock shaft and allowing the cap to rotate via the snap ring will tear up the hole and egg it out. I haven't seen this effect on chrome Molly shafts because the metal is stronger and the cap spinning doesn't have the same effect.

IMO tacking caps on chrome Molly shafts is pointless. But with factory shafts I have noticed an increadable increase in the life of my axle shafts whether it was my d35 ttb, 44's or my current 60. Every time I tried full circle clips the ears egged on stock parts.

On my stock shafts the ears were deforming because the cap was rotating. Once I prevented the cap from rotating I never had the same issue. When I ran full circle clips the caps would get loose, but the full circle clips kept the cap in the ears. But I would have to replace the stock shafts all the time because they became to loose.

Once I started putting two small tack welds on the top of the caps to the ears I never deformed the ears again. I have been runing the same joints on my inner shafts for almost 4 yrs. Occasionally a tack breaks and I grind it down and retack. I only mention the inners because I changed my stubs two yrs ago to 35 spline.


I believe he has chromos in his 30, as long as the full circle clip stays seated I see no benefit in him tacking his caps. IMO tacking the caps doesent add any strength to any components. It simply keeps the cap from spinning.


John,
Your explanation makes sense. It has nothing to do with the cap rotating in the bore. It has everthing to do with the ear deforming and the cap then coming lose.

So, with your explanation, 2fst4u tacking his caps will still have issues.
I believe the ear deforms because the cap rotates. I don't see the tack itself as keeping the ears from deforming. But the tack keeping the cap from rotating deforming the ears.

my last jeep had 36 iroks on a 30/8.8 combo and held up pretty good, I put tj shafts up front with the caps tacked in place and only broke 1 axle per trip, but I had a pile of spares and a trailer so I didn't try not to break it.

If I tried to not break it I am sure I could have made axles last quite a while.

I have a D30 with chromos, lock right, and 4:88's. The ONLY time I messed up a shaft was when i was to retarded to know to put full circle clips on them and the clip broke and the cap popped out and then the shaft ear grabbed on a hub assembly bolt and twisted the ear. I have broken 4 u-joints in these shafts and never hurt the shaft. Now i put a stocker on the short side and tacked the stock side and full circle clipped the chromo and i broke the stock shaft the first time my front tire came off the ground.

A big difference i have is being on 35x13.5 Krawlerz. These bastards hook onto everything.

I just don't understand the point of going from a 35 to a 36? I don't see that 1/2" of ground clearance making a huge difference.

Why not spend the money for tires on the axle upgrade?

For what it is worth ...
I have been running D30 with chromos, Detroit Locker and 4:56's for about 7 years with 36" TSL swampers .. had my first breakage last Oct. sheered the teeth off the ring.
When I break again I will be upgrading the axle. Hard for me to justify the expense of axle upgrade.

I wouldn't tack my caps with full circle clips and chromos I'm fine. I don't need a 36 or 37 just want a true 35. I would be ok with keeping my current tires but they're getting worn down. I figure if I'm going to get new tires why not go a tiny bit bigger. I may also regear to 4.56 or 4.88s.

That sounds tempting wade! If only I could afford sitting out this year from wheeling and do the swap
