New TSL SX 35x15.5. have gone through 3 additional tires trying to get 4 that are round. they all balance (conventional balancer) but when on the jeep and at speed there is a bad vibration.the vibe doesnt go away once the tires are hot of cold. the jeep has new ball joints and the drive shaft has been balanced. the old 33's (TSL'S)that came off for the 35's were put back on as a test and the jeep rides like a cadillac so i know its the tires. the local distributer says that the SX's are very problematic. is this something i have to live with or is the distributer full of sh*t. anyone else having trouble with 35" TSL Sx's?????.

if it matters- 1981 CJ7 I-6, D30/AMC20, T-18/D20.

I just got some 36" TSL/SX's and they took a lot of weight to balance. The first place I had them mounted at had their head up their ass and told me they had balanced them. Worst vibration I ever had. Thought I had death wobble or something. I thought it was the rims I had put them on because they were some rims I had gottem for free that had some rock rash and some dents. I took it to another place that knows about 4x4's and they always treat you right. I had bought some new rims and asked them to mount and balance my tires. They could mount them, but couldn't balance them because the first tire they tried need 26 ounces of weight. So it wasn't the old rims after all. Just the other tire place not having a clue on how to balance tires. You can't fit that much weight around the rim, let alone in one spot. He used some of the wheel weight patches that go inside the tires. Those took care of the problems and it now drives like a caddy.

I have 33-15.5s and I'm pretty sure one of them is a little out of round. Even at slow speeds I can feel it bouncing up and down slightly. My rig's not a daily driver and it didn't seem bad enough to go back and bitch at the shop. I just assumed that it was a common side effect of large aggressive tires - especially swampers.

I am on my 3rd set of Interco tires. First two being tsl's and now Boggers. The TSL's werent that bad, but they still took about 10" of lead on both the inner and outer lip of the rim. They would get "flat spots" in them from sitting. The first few miles of driving would SUCK!. but after they warm up they werent too bad. Now, the boggers on the other hand <IMG SRC="smilies/biggrin.gif" border="0">. I bought these used so there was allready some alignement wear and splits in the casing. I had them mounted and balanced at Americas tire. I got in a little Shit talking mach with the bone heads there reguarding a handfull of promises they made and didnt keep. The manager pulled me asside and appologised and told me they would mont and balance them for free. when I got them back, each tire had one or two small weights on them?????? no fricken way thats ballanced! these things vibrate and woble like you could not belive!.

I think allot of the time the idiots at tire shops make an effort to ballance a tire, but when it becomes "incovienent" for them they give up and say "fuck it, good enough"

especially when you piss em off <IMG SRC="smilies/biggrin.gif" border="0">

LOL I have to laugh cause Americas Tire here in Folsom is where I first had mine mounted and balanced. Like you I had a few small weights put on them and one tire had no weights at all. A bunch of friggin morons if thats what they call balanced. I took them up to the Big O in El Dorado Hills and Chris up there did me right. Great guy and the tires came out balanced perfect. I will never go back to Americas Tire again.

You guys actually try to balance a bias ply swamper? <IMG SRC="smilies/eek.gif" border="0"> . SX's are notorios for driving like they are square. I leave mine aired down so when I do ocassionaly drive it on the road they bounce like a mofo. Remember that TSL's, SX's, Boggs are steel belted bias ply tires. They will take a lot of weight to balance if you can get em to. Yes they will drive better after they're warm, because they are to their roundest point. When I used to run Boggs, I tried to have em balanced just for fun. The guys trying it laughed it was gonna be like a pound or more to do it per tire. Also, they will be out of round if you air down and wheel with em, then air back up and try to drive on the street again. Even if they were once balanced. <IMG SRC="smilies/beer.gif" border="0">

The 38.5 sx's I had were used and all 4 had large lead weight patches inside them.
I have two sets of Boggers, the 35-16-15's have never been balanced and aren't that bad after warming up. The 39.5's on the other hand try to dislodge my kidneys.

I ran those 35X15.5s for almost a whole day! Same problems as you. My rig normally road so sweet, and with those things it shook like a strung out junkie! I tried a variety of balancing techniques but no go. The runout on those things was a joke. I thought it was because I grooved them, but then I talked to others running them and they all said the same thing. I called Interco and there customer service was very helpful, and offered to make it right, but they basically told me if you actually want it to drive it buy a radial like the SSR.

I think the 35" sx's are getting a reputation for this. I had two sets. One tire in the first set was terrible and you could actually watch it hop going down the highway. The second set I bought locally so I wouldn't have that problem again and all was good. Then a guy in my club buys a set this summer and has major problems with them being out of round. He had his shaved and that helped the problem. Really didn't need that much rubber off to make them round.

I run the 35 X 15.5 SXs and lvoe them, BUT they are hard to balance and not round. On the balancing machine you can see that they are not round. Mine bounce all over and vibrate like a 'mofo', like the other poster said...... having said that, I wouldn't have anything else. I am mildly considering a narrower tire, but I really like the width. I would really like the 38.5 X 14.5, but don;t want to lift it any more than it is. Bottom line to me is if you are going to run bias ply swampers, this is a bad side effect. If smooth road driving is a priority, get a radial of some kind.

I've been runnin' the 36" SX's for a few
years & really like them. I keep them down
around 6-10 psi year round, running from my
house to the trails. Never had a problem
w/them being out of round. All my wheel
weights have gradually fallen off, but I can
still air them up & smoke down the hwy doin'
65-70 & it's smooth ridin'. <IMG SRC="smilies/wink.gif" border="0">

If only they were a little WIDER ....... How much taller are they than the 35 15.5? I know, 1 inch, but I mean real world difference - anyone ever have chance to measure them side by side?

I had my 35x15.5's powder balanced and they were great up to about 65mph then they'd start to bounce a bit. Below that speed they rode very smooth, I was quite happy. Took it above 65 a few times but after a while the shaking would annoy me. At first it was REALLY bad but then I checked the toe and it was out. FWIW adjusting that made a noticable difference for me. I still have them btw, I speak in the past tense only because they haven't left my garage in 9 months <IMG SRC="smilies/rolleyes.gif" border="0">

when you say powder balanced you are talking about using 'equal' balancing powder int he wheels? Does this work well? How 'bout at lower speeds? I've been considering this option, right now there's like 3 lbs (10 ~ 12 inches) of weights on some of the wheels. It doesn't matter THAT much because I only drive it on the street to get TO the trail, but still, if there is a way to reduce it, why suffer? I know what you mean 65 mph+, mine starts to shake BAD after 65 mph.

I dig my 35" SX's, but each one is out of round to varying degrees. I was able to get them balanced with relatively little weight, but that won't make them any more round. I have some 38.5's going on soon and am interested to see if there is a difference. From what I've heard, the 35's are the worst of the bunch. What could I expect out of a 15.5" wide bias-ply? <IMG SRC="smilies/biggrin.gif" border="0">

i dont know if this matters but my 36x12.5 tsl radials ride great, no wobble or anything..they do have their share of weightson them, each has a really big one that goes on the inner lip then theres the ones the stick to theinside of the wheel. theres a lot of them but they are more balanced than the 33's i had on there before!

I've been happy with it, but I don't think it was called Equal. I heard about Equal later. 4WPW in Oakland ( <IMG SRC="smilies/flipoff.gif" border="0"> ) installed it whatever it is. Maybe it IS Equal, but I saw the bag it was in and I remember it as something different. Wasn't cheap either, it was like $40 a tire or so but that could have been the typical 4WPW reaming (this was when I was naive and thought 4WPW was a quality business).

<STRONG>How 'bout at lower speeds?</STRONG>
Ya know, when I had the tires mounted and asked to have the powder used to balance them they told me there was a guy in there having it removed because it drove him nuts at low speeds. Claimed he could barely control it because it bounced so much around town. I tried it anyway and never experienced what they described. The only low speed bouncing I got was the "settling" that occurs in the tire after sitting for a bit, but that's normal. A couple minutes and that's gone.

I was going to use Centramatics until I heard they stopped selling them for use with large tires on CJ's, and the powder was cheaper. Either one got me what I was after, a continuously rebalancing tire, but the powder was cheaper. I'd heard horror stories about TSL's in general where they'd stay balanced for about a week tops. Plus I didn't want to deal with dropping any weights from catching on the rocks. Only catch with the powder is that of you get a lot of onroad use (ie. a lot of use between airing down and really flexing the tire) then it's a good idea to give the tire a whack once in a while to knock the powder loose so it will rebalance. Supposedly it tends to stick in one spot if left there a while. I'd do it again, but I might talk with Centramatic a bit more. I haven't popped a bead yet (yeah yeah, I guess 5 psi isn't aired down enough) but I can picture seeing that powder spray out if I ever do, and then that tire will need rebalanced. Just an advantage the Centramatics have over the powder, although in defense of the powder I've never seen it come out when airing down. Maybe 4WPW REALLY shafted me and never put the stuff in <IMG SRC="smilies/rolleyes.gif" border="0"> Either way, good luck with whatever you decide <IMG SRC="smilies/beer.gif" border="0">
