Hello
Picked up my GTI Performance 3 weeks ago, purchased as pre reg (April) with 100 miles on the clock. All has been going well but when cleaning it today I noticed that the rear off side tyre is a Continental PremiumContact 6 and the others are Bridgestone Ponteza S001 - something the dealer never mentioned! All are 225 40 R18 Y92 and I'm assuming that the Bridgestones are the VW fit - if not then I really am worried!
I'm no expert on tyres but from the info on the internet it seems that manufacturers suggest that the tyres on each axle should be exactly the same, some sites seem to suggest that it's illegal to have different tyres on the same axis but I really don't think the dealer would sell me an illegal car.
So do you think I should be worried? I'm going to contact the dealer to get them to set out that it is legal and also to explain to me why it was done (I've checked the spare and that and the tools show no signs of being used), but I thought it would be helpful to have some advice first.
Thanks for your help.

The Bridgestones are the usual 18" tyre. The dealer has clearly replaced one for whatever reason, you should not have odd tyres though, it is not safe! Go straight back and complain, I'd be wanting all the tyres the same.
-
New Golf's tend to come fitted with the Bridgestone's if it's on 18 inch wheels.
It's not illegal to have different tyre brands on the same axle, but ideally they'd all be the same. I'd just check that they're all the same size and speed rating. The standard Bridgestone's are a Y rated tyre.
-
It’s just not nice to have odd tyres on a very nearly new car, is it? You might want to have the wheel with the Conti on checked for damage, too. It’s not easy to wreck a tyre without doing something to the wheel. Why would anybody, who knows anything about cars, have a Conti put on anyway? Just as easy to fit a Bridgestone, and they’re usually cheaper too! Weird
-
How strange. Maybe the original wheel was damaged and was swapped with another wheel that had a Continental tyre on. I'd check the tread depth on the Conti too to make sure it's a new tyre.
It's not illegal to run different tyres but it's advisable that you run the same.
-
One argument that might help is check the date of the odd tyre. Hopefully it’s older.
Also find a quote online saying you shouldn’t have a mixed tyres on an axle. Especially on a performance car. I bet a manufacture or someone like kwikfit say that !
Also, is the tread depth different ?

@ianj37: Assume your wheels are 18” diamond cut Parkers if your tyre size is 225/40 R18. If the dealer fits a new matching tyre (as they indeed should IMO), check the wheel for damage carefully after they’ve fitted it, as diamond cut alloys are easily damaged by inexperienced tyre fitters, and a job like changing a tyre is probably given to the workshop trainee / apprentice technician.
It’s not unknown for dealers to damage your wheels when they change tyres. I had a couple of wheels replaced under warranty on my previous car, and it took a number of attempts by the dealer at getting two perfect wheels that I’d accept; admittedly some of the replacement wheels ordered by the dealer had manufacturing faults, but some were damaged by the dealer when fitting the tyres!
Forearmed is forewarned - ensure the wheel is clean and take some photos of it before the dealer changes the tyre - and get the dealer to agree the wheel is in perfect condition. That way, if they do damage it, it’s harder for them to deny causing the damage.

It's not safe away an stop talking nonsense it might not be recommended but it's far from being unsafe :smiley:

I'm not 100% sure exactly what you mean by the first part of the above? As for far from being unsafe, I beg to differ.

As with many things in life that aren't recommended, you could be absolutely fine and have no issues until you encounter certain circumstances when it could contribute or even cause an accident. That is not safe.
-
It's not illegal but not recommended either.

I had this a few years ago with a dealer, it actually said it in the MK5 handbook, that tyres should be axle matching pairs, possibly still says in current handbook, haven't checked. Dealer didn't care, had a right back and forth with them, VW customer services didn't give sh*t either.
As others have it is it not illegal, but far from ideal, just fight them, they don't come out of the factory like that!

Thanks for all your helpful advice. I've checked the manual and it doesn't say anything about tyres from different manufacturers on the same axle, just make sure it's the same size, rating and tread pattern. I've taken some pictures as suggested. Emailed (so I have an audit trail) the dealer and I'll report back what the outcome is.
Thanks, Ian
-
It should be illegal to have 1 grippy and 3 slippy (Bridgestone) tyres, but it's not - just ill advised to do so.
If the Golf manual advised against mixed tyres across an axle then I'd say the dealer should be compelled to follow that guidance. Does it?
-
Ok, the dealer has got back to me, apologetic, and is replacing the tyre. No indication why a new tyre was needed but I'll try and find that out when I go in.
This creates another question though! As I said in my initial post I know nothing technical about tyres but a quick google seems to suggest that the Premium Contact 6 gets better reviews than the Ponteza S001 and monkeyhanger's comment seems to back that up, so am I better asking for them to put another Premium Contact 6 on to make a pair (and possibly putting these on the driving wheels rather than having 4 Pontezas?
Monkeyhanger - I've checked again and there is nothing about different brands on the same axle in the handbook they just have to be the same size, rating and tread pattern.
Thanks

Continental and Bridgestone have different tread patterns so it should be two tyres of the same model in theory.

That depends on which tyres you want to be replacing first. I'd expect the Conti's to give better traction through the driven wheels. But the Bridgestone's will still be ok in the summer months. But when the temperatures begin to drop in the autumn the Bridgestone's will be as hard as granite and if you have them on the rear axle they'll likely last until the end of eternity. Great if you want tyres that last, not so great if your priority is grip.
