Strange Tyre wear on front of WJ ?
 

The front tyres on the Grand Cherokee have started to have a strange wear issue after 28k miles.
It is mainly on the front outer edges but extends to the centre in places, the block part of the tread is ripping off in small chunks. (Goodyear A/T Wranglers) The tyres replaced identical ones that wore normally.

The tracking is good, no suspension wear shockers are okay. My garage say it's from driving on hard stone chippings and is as a result of driving with almost full lock causing the stones to cut the tread. They reckon it's common on Range Rovers.

The local tyre depot I use scratched their heads a bit - they ruled out tracking as the tyre is actually quite smooth across the width with even tread wear depthwise. They thought it might be a combination of uV degradation of the tyres (made in 2017) and turning on hard road surfaces.

Anyone here had this problem when off roading etc ?

The link does not seem to open at a page about tyre wear.

I am even wondering if it could be pothole damage !

I get a bit of Rock rash from off roading but never had chunks coming off the tyres.
That sounds like delamination of the tyre.
Never used Goodyear wrangler tyres so can't really comment on how they wear.

Tyre Delamination.
 

TBH that was my thought, although both front tyres are affected the offside one is much worse. It also happens that when I bought the tyres I purchased two from CostCo who were really arsy about fitting two instead of all four, a week later I bought the second pair from National Tyres.

Am beginning to think it's a tyre issue, I missed a year out in the miles covered they have covered around 24.-26K miles since June 2017.

Will do a front to rear swop and monitor them over the next few weeks.

Another thought is maybe they are a summer tyre not all season which would explain the difference between how they are wearing as they are a different compound:nenau

One Wheel nut will not shift
 

They are normal all season tyres, was going to remove the locking wheel nuts this morning and one will not shift.

My impact wrench will not shift either it so will wait until my mate turns up this afternoon and try my big socket lever. I will hold it in whilst he gives it some muscle. Tyre depot or garage have obviously over tightened it!

I hate locking wheel nuts.
 

We failed with a 3 ft socket bar. Mates Milwaukee Impact Wrench saved the day - locking nut is cracked on the key head so will bin them and have normal nuts all round.

The only people they seem to frustrate imho is vehicle owners - rather like radio codes when they were popular.

Those were the days!!!! I remember selling Ford M Series codes from a calculator I downloaded from Limewire [emoji38]

You used to launch it and the calculator GUI would be the same as the stereo facias itself.

Put the serial number in and out pops your 4 digit code, £5 please sir, now make sure you marker pen that on your case
