Hi Everyone,

 

Just purchased my first VRS [what a beast....fallen in love!] and just noticed that i have 3 pilot sport 4's [2 on front and rear left] and the back right is a bridgestone potenza.

 

Is this an issue? All 4 tyres are in very good condition.

 

Any views would be greatly appreciated.

 

Cheers!

I shudder whenever I follow a car and I can see that the tread patterns are different on the rear tyres.

Under braking conditions there is no possible way that two tyres from different manufacturers will act in the same way. One of those mis-matched tyres will brake better than the other and you run the risk of the back-end sliding out.

If conditions are wet, then this could be exaggerated.

Now it is probably safe to say that you aren't using the tyres to their limits, you're probably not going to be braking from anything much above 85mph and you won't be in monsoon conditions when it happens - however, those two rear tyres are always going to act with different characteristics.

 

Personally, I don't do it. I'll happily have different makes/models front to rear, but I won't mix on the same axle.

Hi Stoofa, thanks for your reply.

 

Thats good to know, even if its not what i wanted to hear! Makes sense though. Will have to get it changed.....

 

Is there much of a market for good condition second hand tyres?

 

 

I'd say that alloy had been replaced with one from another car/source as it sounds like it's an oe fitment bridgestone. They didn't ever come with full size spares either. No one in their right mind would pay to fit a mismatched tyre on one side of an axel would they?

It's best to have all 4 tyres the same.

 

Both front tyres matching and both rear tyres matching generally isn't too bad as long as they're decent tyres. Having different tyres on each side of either the front or rear or differently worn same tyres (replacing one side but not the other) is very much discouraged as it can cause all kinds of handling problems, often when something goes a bit sideways and you most need the car to keep its stuff together.

Maybe they had a puncture and nearest tyre place did not have the pilot sports?

Ok will bear that in mind. 

 

Sounds like 2 new tyres will be needed the. Sad face

The majority of the cars on the road will have mixed tyres and officially it is perfectly safe so long as they meet the tread requirements. Ideally its nice to have all the same. BUT if you put someone in it without telling them they wouldn’t be able to detect they are not the same. Certainly not between premium tyres. Lewis Hamilton on a wet track might detect something but doubt that too in an Octavia. 

 

No way on this planet would I waste money changing it.

Finally some sense being said!...if the odd pair were on the front I’d say swap them to the rear but if all the tyres are in good condition and your happy with how it handles, I wouldn’t waste your money changing it just yet. 

Should be fine as abs and esp will sort out any grip differences as it is not a odd winter tyre or cheapo budget tyres I wouldn't lose any sleep over it and just run them down as shame to waste a perfectly good branded tyre.

Thanks for all the views. Appreciated. Yes does seem a proper waste to change them. Handles very well but not really pushed it too much yet. 

 

Will have a think about it

 

Leave it, it will be perfectly fine just wasting your money if you change it wait till there worn out 

+1 more for definitely leave it. If it bothers you, swap it onto the front so it wears out faster.

no way I'd leave it. Unpredictability is the problem, and the difference will be most noticeable as it's on the rear axle. That's the one that gives you stability, especially when braking. 

 

Your call; the cost is what, £150? Why risk it?

If your driving to the extreme that you cant predict what your cars doing then you need to slow down, its a skoda not a mclaren ,leave it alone its perfectly legal there good quality tyres whats the worry

I'd leave it. You could get a puncture at any time and be in the same situation. Even if you could get the same type, it would have different tread depth so handle differently.

 

If it bothers you, put them on the front as that will wear them down quicker needing  sooner replacement than if they were on the back.

Precisely. If the Potenza has a similar tread depth to the other rear and feels unsafe, you’re probably going too fast for the road conditions and/or your own capabilities. 

Really, honestly, you've never hit a puddle too fast? Never had ESP react on the road? No unexpected mud? 

 

There's "inappropriate speed" and there's "code brown" moments. You don't get to predict the latter. Personally, I like to make sure I take as much unpredictability as possible out of the car to give me a better chance. 

I've hit at least two of these over the last few weeks on the ice and snow - Cruise will disengage if ESP starts to do something - and the car dances way earlier than you might think. "You're driving too fast" doesn't apply when the situation changes in a split second in front of you. You can drive as defensive as you like: aggressive preparation is the only way to understand what to do and how the car will react when things go south sharpish.

Been out and measured the tyre depths this morning.....

 

The pilot sports are all on 7mm and the potenza is on 4mm.

 

Given that new tyres are 8mm i am going to purchase a new pilot sport 4 to replace the potenza

Spelling error

Been quote 113 fully fitted by local garage for th PS4 which seems reasonable

This is exactly what I would do in your situation.

If the Pilot Sport on the same axel was very well worn, I'd say bite the bullet and get two.

1mm down, yes the two tyres will react slightly differently, but in my mind that really isn't far off being new.

It is why I put a full size spare in the cars when I can. Then I am fine until I can get another proper matching tyre, not just what the first place has on the shelf.

 

It is not the worst thing to have an odd tyre but I'd rather not. 

 

Given the tread depths, putting a single new one on is what I would do. Near Side Front is where I put mine as it wears most going round islands, it will end up same as the others soon enough.

That sounds like a good idea. Cheers

I’ve got mismatched front to rear, the fronts hankook, the rears continental. 

I’m hoping to get them changed to all matching next week, then once they’re bedded in - the brakes as the discs (according to main dealership) are unevenly worn.

then it’ll be the battery, goodness knows what next!
