Tire questions

[nspctr1]

I have a tire out of balance on the 998 and having trouble finding anyone in the area that will balance it. It does have a little dry rot but nothing serious and am looking at replacing when I get the $. They still have the run flats in them with stock rims. Could the inserts be causing the issue? Can you run without them? Sorry if these are dumb ? but new to this.

Thx

If you are wanting to balance the tire, that means you are running it on the highway. Dry rotted tires and speed/heat don't mix. Save your money and get a good set. I'm not trying to be a Betty Downer, but we already have enough problems with the Humvees that are in civilian hands.... A bad tire day that makes news headlines is just another way for the man to say--- I TOLD YOU SO!!!!

just find a real tire shop, big truck tires and tractors had mine balanced with the runflats in them no struggels

 

[Lawdog734]

Are they not balancing them because they're dry rotted or because they're too big? Most shops won't touch them if they're starting to dry rot, in which case do what you know you need to do and replace them. If it's because they're too big, ya just need to find the appropriate shop.

What Lawdog said... If tire size is an issue, find a place that has a Hunter Road Force balancing machine.

I had the same issue when I got a new set of MTRs for my truck. I called about a dozen places that wouldn't do the tire because of size.

Finally found a shop that said they would and that is the machine they used. They said they had done up to 40"x15" tires on it before.

Yes, the runflats can cause out of balance issues. To the point where the shop can keep adding weights but all it does is make it worse. In that situation, you have to rotate the tire in relation to the wheel. One of mine needed that done.

And to answer the question on running without the runflats, you can but, you will lose the beadlocking of the wheel. This is not a good idea because the design of the tire and the wheel really need the beadlock to operate safely. It will also let you air down your tire to lower usable levels off road. If you do get a flat, the runflats can keep it from turning catastrophic especially if you're operating at highway speeds. This is a big tire after all! If you do decide to operate the wheel without the runflat assembly, at least get an aftermarket PVC beadlock to keep the tire safely on the wheel. Personally, I think that aside from the extra weight of the wheel and the higher difficulty balancing the wheel, the benefits of the runflat assembly far outweigh the issues.

To improve the balancing further, you can also get a set of Centramatics that will actively balance the tires. This is on my short list to add to my truck.

Throw some beebees in the tire and call it a day.
but I would not run that tire on the hwy at all being dried out...

Trying to put bb's in the tire is useless with the run flats in the tire. Unless you live in a hostile area, and plan on getting your tires shot out from under you, take the run flats out. You will never air your tires down to 20 PSI for off-roading. So, with that said, no run flats, you can add 3 to 4 oz. of air soft bb's to your Good Non-Dry rotted tires and should have a better ride. Any commercial truck shop should be able to balance your tires.

Why wouldn't you air down to 20psi? The standard M998 tire spec is darn close to that, so I don't see why you wouldn't.

As for removing the run flat, they aren't hurting anything by leaving them in, so why bother - they're still capable of being balanced. Having the run flat is also of benefit as it let's the tire down slowly in the event of a blowout, and it also allows you to travel to a more appropriate location to jack the vehicle so that you can safely change the tire. It's not just about being shot at.

Check this out - nobody shot at me or anything. Just traveling off a mountain to safely raise the vehicle.

I will continue the search for a tire shop the services big rigs/tractors. In the meantime, I aired the tires up to 35 psi today and drove about 30 miles. The wheel hop is almost gone but not 100% . I rarely drive over 50 mph and have only been on the interstate twice. I prefer the slower roads. How long can I run 35psi? The decal on the fenders says 45 psi so I figure 35 wouldn't be bad and probably won't go off-road at all.

I had my tires replaced by les schwab. They are a little hesitant about the run flats but they figured it out and did a pretty good job.

You don't have to say anything about runflats or the size. Just call around and ask if they have the Road Force Touch GSP9700.
or

My suggestion is to find a shop with a Hunter GSP9700 Road Force balancer if you want them to be perfect.

Go to www.hunter.com then click on Wheel Balancers, then click on Road Force Touch to learn about the balancer and the new higher speed of tire rotation.

Then, at the bottom right of their home page you'll see a line that says GSP9700.com and click on that link.

When you click on that, it will bring up a another page and at the top of that page you click on Locate a GSP9700. That brings up a page you can enter your zip code in, and it will list all of the shops in your area depending on the distance you selected, starting with the closest one first, that have this equipment.

Find a four wheel drive shop in your area that sells tires, they are use to balancing large tires.

 

[nspctr1]

Actually, went to 3 four wheel drive shops in the area and they wouldn't touch them. they all said it was because of the split rim. ****, they work with bead locks don't they? Oh well

35 PSI is a good level to run the tires at.

My truck has 20 front, 25 rear decals on the fenders which matched what I saw in the TM. Was running my tires at that and the ride always felt a little sloppy.

Saw a post from RWH on here to run them at at least 35 for street use. Aired the fronts up to 35 and the rears up to 40 and the ride vastly improved. Have put about 2,000 miles on the MTRs at those pressures so far and everything looks and feels good.

View attachment 671871[/IQUOTE]I wouldn't air down below 20 psi without runflat installed... Nobody shot at you and didn't have to. If you run any tire on its side wall its going to shred like that--- run flat or not. Also if the tire BLOWS OUT, a run flat will not save the day

It's not a matter of shredding the sidewall - agreed that it would happen regardless. The runflat does allow you to safely and certainly more easily travel though if you do have a flat tire so that you can get to a safer or more appropriate area to change the tire. It's a lot easier to drive on the runflat than it it with the tire flopping on the rim. Again, since it's not really hurting anything - IMHO, I just don't see the big deal with taking them out.

I've taken runflats out before - it's more trouble than it's worth just getting them out and then getting all or as much of that grease out as possible.

 

[infidel got me]

The point I'm trying to make is that the more mass, the more weight. The run flat is more mass, therefore requiring more weight to balance. Like a big truck needs big brakes to stop vs. a Toyota camry. I take the run flats out of mine if I change or do any tire work. I don't hate the run flats, just stating that a better balance will be achieved if they are removed........ Another note, the bfg Baja's ride 70% better than the goodyear tire, at least the set that I put on.

That is not a (split rim) it is a two piece DOT approved rim. You are telling them things on the phone they don't understand or need to know, just ask if they can balance a 37" tire. If any of them look at it and say that it's a split rim and they can't do it ask them to Google split rim. Split rims are very old and almost impossible to find now and were very dangerous but were not bolt together rims.

Brother you wrong about the air pressure when off road and the beadlock runflats. The CTIS systems go down to like 9lbs in emergency mode. Also the runflats definitely help in a blowout at speed i have had one with and without recently on the same vehicle and position one tire with runflat hit a piece of metal in the road at 70 and the runflat kept the truck much more stable thane the non runflat setup at 65. The runflat allowed me to slow down easily and go about a half mile to an exit to pull off the road, the non runflat or beadlocked tire caused damage to the truck and emergency shutdown at speeds that were much more dangerous to me and other drivers and couldn't get it to a safe spot to get off the road thanks to the nice highway patrolman and Deputy I was close to home and got my wrecker to get it home. I will have runflats in all my setups that i can from now on, well worth it.
As to BB's in the tires only if you clean out the grease that is in there for the runflat and that would mean removing the runflat, no thanks. A good tire shop not run by uneducated teenagers will balance them without any problems.
