Any ideas as to the cause? If it was just wear, I'd guess the toe was out of adjustment but the cupping would suggest something loose. This is on completely stock setup.
Any help would be appreciated. |

Do you have the stock tires? My tires cupped with in a mear 20,000 miles and were useless. I now what the Bridgestone duelers and so far no problem!!! The Michelin tires are no good!!!! |

Hey Milan,
I would suggest going with the new kevlar tires from Atlantic British. These things are super tough and can withstand speeds of up to 345 miles per hour. And the police can't shoot your tires out. |

Rollins,
Yes they're the stock tires. I will be buying MT/Rs soon and just wanted to take care of any problem that would cause cupping of the new tires.
Scarecrow,
I like the bulletproofness of the tires you suggest but knowing I barely reach one third of their speed rating, I'll stick with MT/Rs.
Any other ideas? Anyone?
Thanks... |

Just to be on the safe side, run by a tire place and make sure everything is in line.. I dont know what it is about the stock tires. I put 3 brand new sets on mine in probably 2 1/2 years. And we all know that they dont give them away!! good luck!!!! |

Milan - have you checked things like the panhard bushings? How about the tie rod ends - are any frozen or just not moving well? Wheel bearings - any wobble in wheel when you rock it top-to-bottom? Any looseness of the pitman arm?
You know your shit, so I'm sure you've already checked all this stuff - but I'm just throwing things out. The XPC's are damn tough tires, so they I'd seriously doubt they're at fault. |

Thanks guys.
Rollins, I believe you, and I see this exact wear on almost every Disco 1. On the other hand the tires are tough for on-road and people report high mileage on these.
Bill,
Thanks for your confidence in my abilities, however, I'm a lazy bastard so I have not checked yet. I will though. I see this wear on many Discos and was wondering if it was a trend or some typical, common wear item. It's just too fricking cold again to work on the darn thing, so I have not looked. Would you believe we got snow last night and it's staying on the ground??? WTF? It is May, is it not? I know the steering stabilizer is shot, could that be it? |

You could install OME springs/shocks like I did, my '95 now wears horribly on the outside (front tires only).
Maybe you can strike a happy middle with some suspension upgrades. Cheaper than a new set of tires! |

I have never seen a stock Disco with stock Michelins that weren't cupped, mine included. Back when used D1's were still on the lot, you could see that black/white checker pattern on ALL the tires!
My tire shop suggested that the full-time 4WD leads to the cupping. Insufficient rotation contributes to the problem, as does poor shocks, misalignment, loose steering components, wheel bearings, etc.
My wife's full-time 4WD Explorer has a set of severly-cupped tires on it. I just replaced the shocks (which were completely shot), and will be doing tires soon. |

Check your shocks! My truck with 138K miles, Rover Tyme lift, etc. wears its tires perfectly true.
I also religiously rotate every oil change.
Peace,

yep Paul - my tires wore fine after new shocks. Now if I could only keep these damn things balanced....... |

Bad shocks or bad shock mount bushings (not tight enough). Cupping can be traced to worn components 99% of the time. Now inside tire wear (not cupped) would be a different story. |

Thanks guys, that's exactly what I was thinking and hoping for. Well actually I was hoping it would not be the shocks as I only have 30K on my 96 - I think I put more miles on it in the last year than the previous owner did in the 5 years before that.
I have OME shocks on order and once they get here, I will do the suspension lift (finaly will have all the components) including bushings. Hopefully that'll take care of that. I will be buying new tires anyway as I want to go bigger. I was just hoping to save the stock ones for resale. Since they're not too bad yet, I may be able to do that.
I'll report how it turns out.
Thanks again for all the |

My hubs needed to be repacked which caused my front tires to cup on the inside.

Andy:
I find it difficult to believe that bearings lacking lubrication would cause tires to cup. If the bearings were so sloppy as to allow the tires to move (or be moved) enough to cause visible tire wear, those bearings would have required replacement, not merely repacking grease.
Milan:
If you wish to resell your tires, why not take them to your local tire shop and have them turn the tires on the rim so that you can wear the inside on the outside (after turning on rims) thus equalizing the wear so they look resellable?
Peace,

Yeah Paul, no worries. That's exactly what I may endup doing. I too believe that repacking would not do it. But maybe Andy's were cought before the bearing got damaged and torquing them properly after repacking fixed that. Although, like you say, bearings go pretty quick when left loose. |
