Thanks Dave!

At the moment I'm in a quandary

I normally replace tires when they get down that far...But do I want to keep buying the 35" Toyo??

Cheaper thing to do, that's for certain.

But I am still considering going to a 37" or 38" tire.

And switching to a 17" wheel. 17" tires are WAY cheaper and there's more sizes available.

If I had to make a decision today, I'd buy 5 wheels, same as I have now, just 17 X 9 and dump the 18's. I'd mount up a set of BFG AT KO in 37/12.50 and call it a day.

But Yokohama makes that MT tire in a 38" 13.50 fitment so that may be a consideration, but I'd be back to the rapidly wearing mud tire again.

I do get off road nearly every weekend, but not into anything that serious. So the BFG AT, which I have used before and found to be an excellent off road tire could fill the bill.

What I do most of all is driving on these curvy roads and try to maintain some semblance of speed, and that takes a handling tire over a mud tire.

So I'm still thinking it over, but I am coming up on having to do something...

too bad you don't have 20s.  I'll be divesting my 12.5x37x20s Toyo MTs soon.  They have 10,000 easy miles on them and are barely worn.

Dumb question. Will 17s fit the LML? pretty sure LMMs had them, not sure on our newer ones.


...never mind, I googled it. I guess some came with them.

My spare tire/wheel is a 17

I do believe the LML came with a larger front brake, so it was a valid question

Don,
I have the same wheels you have on my LBZ, in the 17 x 10.  I found that with the nine wide wheel it was hard to get even tire wear  so I switched to the 10 wide wheel allowing less ballon. I also have bfg ATs with 40k miles mostly freeway.  Fantastic tire and the new model should be even better

Don, I think I've read that 18" is the size to stick with because the 17" tires can't carry as much weight and there's less selection in a 17". I may be wrong though.

Dave,

You have an LBZ, which has a 8 on 6.5" bolt circle

My LML has a 8 on 180mm bolt circle.

Unfortunately Mickey T wheels do not fit

I am using the Pro Comps 18 X 9

Ok front tires are what I measured.  I do not have a locker but I have a hard time wit not launching from stop lights


The profile photo show the slight crown of the tire.  I run low tire pressure as I am not usually pulling.  But the more narrow of wheel the harder it is to get good tire wear. 
Rear tire is a little worse off
I also run a fifth tire that I rotate in


Edit regardless of the wheel brand the ten inch wide is the important part. Specially if you move up to a larger tire

Dave, there is no snow it can't be that cold ?????

Mine had 16s all around, now 17s with a 16 spare. I went with the 17 for the same reason, a lot more tire selection for the $$$. I also went for 9 wide as I don't like a tire that really sticks out a lot.

Compare tires at the shop Don. Roll em out next to what you have. Remember well clearance too, GM is not friendly there.

The wide fender mod is right up Don's alley.  I did it and loved the clearance I got.   There still is no way I can even think about fitting 37s on my truck. 

Jr it's not that cold only forties but I was snuggled with a warm kid in my arms

Hmm... I may be wrong (wouldn't be the first time!) but I thought I recall reading some posts over on DF about this and that's why I made my decision to go to 18's when the time comes. Hopefully at least one of us will learn something new from this! ;)

Just another option to throw in there and rattle around in your head. I really like the Cooper ST MAXX tires. They do really good for me on the road and great off-road. The road noise is low with just a little hum. I have read where some complain about them being squirmy on the road. I have not experienced this. I think that the causes of that are the ballooning tires and wrong air pressures, but people find it easier to blame the tire than admit they did something wrong.  They don't drive like the stock tires did, but I can still maintain plenty of speed in curves. They are offered in 37-12.50-17 also. It don't hurt that they have "Made in USA" on the sidewall either.

The availability by size greatly depends on brand.  It would be really hard to say for sure.  It does seem that 37s are a bit hard to find in an 18.  It is very true that the 18's usually carry a higher load capacity than an equivalent 17.  I'm very happy with my new Toyo R/Ts in a 35x12.5R18.

I was doing a couple things around the truck today. First I adjusted the lights, since the long range lights had loosened up and their aim was off. After that, having recently cleaned the engine over at the truck wash (They do an outstanding job!) I wanted to seal the hood to the grill somewhat. I have noticed that crud will migrate into the thin opening on top of the grill, travel over the top of the radiator cover and dust up the engine causing the truck to become a total loss!

So I scored some closed cell adhesive backed foam used to seal toppers to truck beds and laid down some

Something weird happened

C-Max is my daily driver, since I had to relinquish control of my Toureg (The chick car) to the lady of the house.

Obviously I am putting the miles on it as I find necessary. It sees its share of off road as well as highway excursions and tows medium weight stuff on occasion.

I took it to the tire store Friday to get the tires rotated, since that Grizzly Locker and the slick winter roads has had their due effect.

They rotated the tires, then set pressures, and gave it back to me. Upon leaving I went into the first turn and nearly lost control! The traction control light came in and the thing began bucking from left to right. I didn't know what the heck just happened! I mean all we did was to swap the tires front to rear, no balancing since I use internal tire beads.

After getting home I found the tires inflated to 80 psi rear and 60 psi front. I adjusted that to 60 psi all around and let it be. Well along comes Sunday and off to church. On highway 75 I make a steering input, and same thing. Violent bucking and almost loss of control with the traction control light on!

I'm miffed. Have never seen this except once when driving my F250, with a set of General mud tires on it, a belt broke and sent me end for end across a couple lanes of traffic.

Well, I can't fuss with it forever and it is unsafe to drive, so I called the tire store and told them to get me a set of BFG AT2's, a set of Toyo AT-2 extremes and two more Toyo MT's. I figure I'll decide when I get there which ones to get. Leaning toward the AT extreme Toyos...

Strange. I keep mine inflated to 50 front and 45 rear. I would look into the traction control as I don't see the tires alone doing that with no electronics involved.

Unless they damaged or brake the antilock sensor. Do you have 1 on the diff or 1 on each wheel?

What type of speeds are we talking when this happens?  It seems odd that a tire would just so happen to go bad after they did work on it.  If you can, try and repeat and then turn the Traction Control off and try to repeat again.  See if it is in the Traction Control system.

Not going to experiment. The fronts are down to about a third of tread depth, going to replace them since I really need to do that anyway.

So you order 2 complete sets (or did you mean a set meaning 2) of tires, PLUS two of what you already have for a total of 10 tires, IOT see which tires you like better?

I like your style.

Sounds like the anti-lock brakes computer and/or the traction control unit gone crazy.  Wonder if the pinched something putting it up on the lift?

So you order 2 complete sets (or did you mean a set meaning 2) of tires, PLUS two of what you already have for a total of 10 tires, IOT see which tires you like better?

I like your style.




You got it!

That's what I was thinking...

Well, I just visited the tire shop. The mechanic, Mark took the thing for a drive and confirmed something is amiss. They asked me to wait until tomorrow when I replace either 2 or all four tires then drive it to see if there is a change. While on the lift we will get a comprehensive look over everything.

Did you get some dirt on it driving in the mulch beds at the mall? I hear that dirt is nasty stuff & completely ruins everything.....

Prolly' not enough slack in the rear wheel speed sensor harnesses and when the axle dropped, whammo, broken pieces everywhere!!

...or coincidentally, the batteries took a dump.

Get a dually. No traction control garbage.

Dump the TC, tune or pull fuse.

My bet is ABS since TC normally kills power and ABS controls the brake to each wheel.

I actually think the traction control is saving my butt. It all initiates when I make a steering input at around 30 mph on a country road (Today). I turn left a little bit and the front end takes a much bigger bite into the turn causing a noticeable body roll. When the vehicle rolls, I counter steers then something actuates and you can hear and feel a front caliper bite into the rotor. That straightens it up or causes the roll in the opposite direction which starts the whole process over. I would say the truck is unsafe above 30 mph on anything but a super mild curve.

I could easily believe a shock became disconnected, or a sway bar link broke, it's that bad. But I checked that stuff aling with all the suspension bolts, the tie rods, the ball joints, the rear spring mounts, the silastic shackle and spring bolts. The springs are not cracked and the shocks are attached securely.

The only thing that makes sense to me is the harness got stretched and pinched from the anti lock and a sway bar link snapped. That and the steering gearbox failed and loosened up so much you now sort of row side to side to keep the truck centered. The front tires seem to wander on their own...Toe out to the right, then left then back right, and without the steering wheel moving!

I just thought of something...I haven't checked the steering arm that runs through the steering column...???
