Severe tyre wear on Seal Perf AWD

your saying that the original tyres lasted 35k and the new tyres only lasted 5k? did they do a balance and wheel alignment?

Yeah exactly what I’m saying. And they did both. Fronts are worn down to 3.5mm as well. All tyres are evenly worn across the tyres so no alignment or balance issues.

Has someone been driving the car hard? Someone different from who drove it the first 35k? 35k is a very long way on a set of tyres for a heavy car. That’s suspiciously far. Are you sure the tyres weren’t changed at 25k? 5k would make sense if the car was driven hard with a lot of acceleration and cornering. You can go through a set of tyres in 5k if you drive it like you stole it.

Mostly driven in normal. No harder than the first 35k kms in any way. Same driver. No different driving style.

unless you changed your driving style (considerably) its gotta be a wheel alignment problem... that or a bad batch of tyres...

For conti eco 6 it's about that range of 30-40k kms. Seen many seals changing thdir stock tyres at that range

I just changed my rears only at 38k in a Seal Premium. Fronts still have a bit of life left.

I would be taking it to a suspension place for an alignment, and get them to check for anything that might be rubbing while they have it on the lift. Something isn't right under there.

It has a drive shaft issue which will be repaired under warranty when the parts arrive. Wonder if that has anything to do with the wear.

yeah I just looked at your post history and was about to say thats likely your problem. try to talk BYD into giving you some new rubber.

Likely caused by OP's vibration/driveshaft issues: https://www.reddit.com/r/BYD/comments/1mb5g2l/byd_seal_performance_awd_vibration/

It’s was worse than pulling teeth to get them to fix the driveshafts. Getting some new rubber will be like an appendectomy.

Disappointing to hear regular reports of how shit the BYD presence is in AUS, in NZ they just fix/replace things and give you your car back, no dramas

Any recs on other tyre brands and models if we need to pull out of our own pocket to replace them? Don’t think will go with the Contis again despite it may not have been the issue.

It truly is. Their service leaves a massive amount to be desired. Fighting tooth and nail for months to get an obvious issue fixed at three service centres. I knew the issue as I had researched it and even told them, but they tried to blame anything else so we’d be out of pocket. Finally got a decent service centre that found the exact issue, faulty rear driveshafts and some shredded bearing seals. 3 weeks for approval from BYD corp and 3 weeks eta for parts to arrive. Had a G80 BMW prior and everything was just fixed on the spot with no dramas. You are lucky in NZ if they just do what they are supposed to do. Suffice to say this is my last Chinese car. Experience has been horrible. Other issues with the vehicle as well but minor, some infotainment issues, A/C stuck on high and no control of it. Both vanity mirrors just shattered. Just seems endless. And service pricing has almost doubled from what it was when we bought the car. Suffice to say, may end our NL early and get something else. Even though we will take a huge hit with depreciation.

wtf. i barely got 20,000kms on the original EcoContact 6Q set. if you only got 5,000kms on the second set, sounds like you were sold a cheap clone.

Bought from Bob Jane’s, first set lasted just 35k kms and were less than 1mm all around. Now this second set same tyres, Conti EcoContact 6Q, the rears are at 2mm after 5k kms. Was leaning towards the driveline issue may have caused it which will be fixed in a month or so but trying to get BYD to cover the tyres will be hell so.

On other cars with continuos AWD this is happening because wheels do not rotate sychronuos. Meaning one shaft is rotatimg faster than another.
