My recently aquired 2004 2.5TDI was given 4 new tyres after a bit of haggling at the VW dealers. However they gave me 2 Marangonis on the front, and a Toyo and a Dunlop on the back. I said I wasn't happy but they insisted that this was OK.

I noticed a quote from shipscat in the steering wobble thread where he mentioned "spoke to vw who recomended I didnt mix brands" - I'm trying to find out wher this info came from.

I've called VW customer care and the luxury car customer care but they couldn't help. The nearest I could get was a recommendaton that tyres are changed in pairs.

Does anyone know where I can get a definitive answer to go back to the dealer with?

Not sure about a quote but mixing left to right is definitely not good. Front to back less important but i personally wouldn't mix and i wouldn't expect a dealer to do so. If you'd have turned up with them mixed i bet they would've recommended them to be changed

Hi there,

mixing brands & treads across an axle has always been a no-no on 2WD vehicles, let alone 4WD. Each tyre has its own characteristics for traction, wear, warm-up, for both wet, dry, mud, snow etc so putting two different tyres on a single axle is certainly going to skew the handling of the vehicle in adverse/extreme conditions. If you only pootle around at 30MPH every where it's unlikely that it would be noticeable, but the golden rule is don't mix them.

I'm a little surprised a dealership would suggest such a thing because there are potential libility implications if (heaven forbid) say you had an accident for which the root cause was assessed as being partly due to mixed tyres.
Similarly it is always advisable to ensure your boots are even across an axle - i.e. you don't mix a brand new tyre with a heavily worn tyre - again due to the difference and handling characteristics they will exhibit.
According to the VW Touareg owners handbook - 3.4 Tips and Maintenance : page 53
"All four wheels must be fitted with radial tyres of the same type, size (rolling circumference) and the same tread pattern."

get your question in writing to the dealer (email at least) - if they continue to refuse to resolve it then you need it in writing

I did point this out to the dealer and they said that it meant not to mix summer and winter tyres rather than brands eg Toyos and Dunlops.

Thanks for your input.

The dealer must be working a flanker.
Mixing hard and soft tyres is a recipe for disaster.,so is mixing brands
I bet if you did this on a F1 car Lewis Hamilton would end up sitting on Murray Walker's lap in the grandstand
If the handbook says tyres shouldn't be mixed then that is Gospel.

Your Stealer is trying to pull a cheap one.

Surely "All four wheels must be fitted with radial tyres of the same type, size (rolling circumference) and the same tread pattern" means "All four wheels must be fitted with radial tyres of the same type, size (rolling circumference) and the same tread pattern".

I take it the tread pattern is different on the odd tyres?

If it's any consolation, I used to have 3 goodyears and a hankook fitted following a puncture, and the wear was pretty even for about 35k miles

Hi,

Just to add to this discussion. Got a puncture this morning on one continental and took it and car to independent garage and he noticed the front two were worn down at outer edge (long story but due to misaligned wheels so i knew they were not good) He had one continental and a couple of coopers but would not mix the brands up especially on a 4WD. So picking up 4 Cooper "tires" tomorrow at ?105 fitted, balanced (+VAT) (ps Continentail was ?195 all up for one)

OK, apart from naming and shaming the dealer (Kaine
) I think this might help you:

According to the law in the UK it is permissible to mix tyres across the axle as long as they are of the same construction i.e. radial. Many motoring organisation though take this further and only recommend tyres of the same construction and pattern should be mixed across the axle so aiding equal handling especially in the event of extreme driving conditions. In some countries, such as France, mixing tyre patterns across the axle is illegal. The mixing issue also applies to tread depths as well. A tyre with 7mm of tread is going to have better water dispersion characteristics than a tyre with 3mm remaining tread depth. This means that in some driving conditions tyres with different states of wear may not react in the same manner across the axle. To ensure best and safest driving conditions we advise fitting tyres with equal performance across the axle.

So what I'd say is that you will be taking the car abroad (use France as an example), and that the mix of brands on the same axle would make it illegal.

Also get some advice on the type of tyres on front and rear axle. I think there's a danger with 4WD perhaps and how the car will - or will not - respond in problematic situations.

I have done extensive tyre testing using multiple on board cameras, remote temp sensors, data recorders on all four wheels/brakes and axles, terrabits of data, kilometres of video tape, all of tyres, brakes and wheels in melt down etc.
Bottom line from somebody who worked with some of THE tyre companies, at F1, WRC and Aero. Its not advisable to mix tyres at all. One make, same type all round.
Only exception is where the manufacturer, puts a different size tyre on the front/rear axle.
The essential point is that different tyres react differently under the same presented circumstances.
The dealer is pulling a fast one.
