I currently have Yokohama A539 Tyres all round on my car a 106 GTi. Front left needs replacing and the other is getting done aswell.

Does it matter if I have a different brand to the front as to the back - both left and right sides will be the same and always get changed at the same time but does front to back matter as much given its FWD?

Aswell what tyres do people recommend? will be keeping them on all year round and not to be uses on track only on road.

Budget £160 ish.

Thanks Guys.

Always thought it was the same on each axle that matters not the sides!

Just as I thought.

Now need to decide on the tyre.

Been looking at Toyo Proxes T1-R for £147.28 fitted by black cirlces.

Has anybody had any experience with these? They seem to be getting good reviews.

Should be fine to mix, but the tyre manufacturers generally advise that you have the better tyres on the rear of the car to avoid snap over-steer on standing water, so I'd put the old rears on the front and the new tyres on the rear.

Best overall solution is to rotate the tyres around often enough that they wear at the same rate so you replace all four at once. Bit late for that now, though. smile

I agree, although the difference in performance between the Yokohama and the Toyo might be quite significant and you might find yourself wanting to upgrade to Toyo all round sooner rather than later.

When I first put the Yokohoma on I thought they were amazing? Are the Toyo's that much better? Havent planned to change the back as they have so much tread on them but might at the end of the month now that you have mentioned that.

After aquaplaning off the motorway on mixed tyres I would never fit two different sets regardless of whether same wheels on axle.

Meh. See how you feel I suppose! I run a539 control tyres on my race car and i find them 'okay', but the Toyo is a slightly more performance orientated tyre... as others have said, put the new tyres on the rear and see how it feels. You may find that they alter the balance slightly and make the car more prone to slightly abrupt understeer.

Well it wont give the front end any less grip.

Fitting tyres with dramatically different levels of grip front to rear will alter the car's handling balance when the grip runs out. If the response of the level of grip of the two types of tyre to changing conditions differ, the handling balance will change with conditions - imagine putting semi-slick track tyres on the back and an average tyre with good wet grip on the front, and how the balance of the car would change between wet and dry roads.

The ideal is matching tyres all round, rotated to wear evenly, but that's not always practical - some cars have different tyre sizes front to rear and sometimes tyres get discontinued and you've no choice but to buy something else. Of course you could buy a full set of the new brand, but if the new tyres are broadly similar in construction and compound to the old ones you have to be pretty fussy about handling to chuck away a pair of part worn tyres.

With a 106 GTi, I would choose very carefully.

In my experience T1R Toyos are good tyres on 106 GTIs due to their light weight. Not the best tyres by any means, but still very good.

What difference do you think having different tyres on different axles made?

You think next time the rear tyres will think "Actually, lets not aquaplane, because the front tyres are the same as us"
Because the tyres will have different water dispersal rates meaning greater instability.

An example would be different front and rear tyres.

You go round a rh curve on the motorway and there is standing water front tyres have a pattern that quite happily cuts through the standing water the rear tyres have a different pattern and don't clear the water as effectively and the rear then swings round on you.

Yes but that's nothing to do with them being different, just to do with the fact that one set wasn't good enough for the amount of water. If you'd had the worse tyre on both ends, you would just have had both ends of the car lose grip rather than one. That is however why they say to put the better tyres on the rear - understeer is better than oversteer because when you come off the standing water, you'll still be pointing in roughly the correct direction.

I had them on my old MX5. Nice tyre for the price. Quite soft, so ideal for light cars. They wear a bit quick but I think I was only paying about £50 each for them in 15" 185/50

I just dont think its a smart idea to mix tyres. The example given was merely to put a point across which is that different tyres will react in different ways to different circumstances.
Therefore i dont think its wise.

Also, is the car on standard suspension, or is it lowered?

I ask as, with 16's on standard suspension, doesn't it look a bit tractor-y. That's 2 inches larger than standard, with the same size tyre.

And if it's lowered, don't the fronts rub on lock? Usually if you go to 16's, you'd want 40 profiles.
Yes its lowered and only rubs on full lock! Never been a problem though!

Just to reiterate the point although there performance tyres i dont do any kind of performance driving! Normal road driving is all they will be used for.

No I know you didn't, I was just pointing out that it will only make the car under-steer more if you drive it faster because you have more rear-end grip. I wouldn't exactly expect the 106 to be over-steer prone anyway (although I'm happy to be told I'm wrong) so I wouldn't be surprised if one wouldn't even notice the difference of having more rear-end grip on the public road.
