Passenger side tire cupping

[LiveFreeOrDieTryn2B]

I have the passenger side cupping I saw a thread that exhaust heat can cause this. I eliminated the J pipe and have just an elbow drives side has almost zero wear should I relocate exhaust to the back of cab?My tires are 14.00 20 NATO NDTs

No, well, if you want to, it's your stuff. Please explain how the J pipe causes cupping? Cupping can be caused by alignment issues, over/under inflation, one side braking harder than the other, shock issue or just turning. These pigs are heavy over the front, more so if it is a winch truck.

It's a winch truck bobbed it's only that side that's cupping the driver side still looks almost new.I have new shocks.

The heat from the exhaust softens the rubber as you drive especially in the summer.I have lockout hubs as well I will be doing brake pads and drums in a week or two.

I'm not sure but changing the perches may help with the big tires.

Ya I'm not sure what's going on but I will be doing pads and drums and try to eliminate some of the potential causes I'm not sure don't have any vibrations and no pull in the steering could be brakes or could be the exhaust heat building up in the tire as I drive .

What? The heat at that part of the pipe when driving ain't enough to soften the rubber to cup. IF it got that hot, there would be a tire failure. ****, the exhaust on new trucks id 1000 degrees + at the outlet of the pipe. That means that every truck running around, actually WORKING would be failing the front set of drive tires due to the exhaust going directly onto the tires.

You have another issue, NOT the small amount of heat at the lower point of the J pipe. I put thousands of miles on my junk and never had issues caused by excessiveheat from the pipe. I used it alot in 100 degree heat here in Ca.

I would check wheel bearings first.

I am taking the front end apart tomorrow dropped the tranny today.I will check all that have to do brakes boots and seals in the front Axel.

 

[HanksDeuce]

Is it the inside or the outside of the tire that's cupping? Have you checked your toe (in or out)? All the same tire pressures? Truck doesn't pull to the right?

 

[LiveFreeOrDieTryn2B]

The outside of tire on passenger side

 

[Scrounger]

That is classic toe in problem. The tires are toed in to much.

 

[LiveFreeOrDieTryn2B]

Can I fix it ?I only have it on passenger side.

 

[LiveFreeOrDieTryn2B]

The truck runs beautiful like a sewing machine with the LDS engine I bought that was rebuilt in a can.

 

[WillWagner]

Could be steering component too

 

[LiveFreeOrDieTryn2B]

Need to do front wheel seals need to do brake pads and drums as well as at minimum tranny seals and gaskets.

 

[LiveFreeOrDieTryn2B]

I lol have to get it apart tomorrow and get pics I have a thread and pics on tranny up with pics if y'all want to take a look.

This post on abnormal tire wear should help. Post number 3 refers to toe in adjustment.

So my toe in could be out on that side?

 

[LiveFreeOrDieTryn2B]

My tires don't sit flat on the ground I thought I read you couldn't fix that.They bow inward.
