**Unofficial Tyre Thread**

Depending on your tyre size you might not be able to get the GY A6.

The PS5 is available at Blackcircles/Asda Tyres/camskill (delivery only). The side wall looks cool too
I definitely can't get the GY A6 but there are plenty of well priced mid range tyres that aren't a generic brand.

I'll be getting the Toyo Proxes CF2.
 
My A7 needs 2 new Bridgestone turanza T005. Being 255/35R21 they are not cheap!

Anyone have any experience of Costco tyre fitters? (pacifically Leicester Costco) Being diamond cut 21" very weary where I take it. Are they alloy butchers or are they good and safe to use?

Surely it doesn't need 2 new Bridgestone turanza T005 - it needs 2 new tyres! :D

Continental Sport Contact 7 is another choice in that size, which is probably a better tyre (and is very slightly cheaper - at least on Blackcircles)

Want to keep them the same as the front. Don't like mixing tyres.

Had the fronts done last year but place that did them are a lot more expensive this time around.

Managed 26000 miles so I'm happy with that.
 
I called up a tyre place yesterday and asked for them to get me 3 times Toyo Proxes CF2 in 185/55 R15.

They said that the importer has no more stock. Email black circles as they claim to have stock online and they said yes, they have stock.

I order three tyres yesterday but I'm pretty sure that they aren't going to have any on hand. You know when you can see the end result but the company can't? One of them situations.

Blackcircles are likely to have their own warehouse/distribution network though that may already have stock available, rather than relying on the "importer"?

I've never seen an "out of stock" tyre on Blackcircles (at worst I've seen some with "we can fit on XYZ Date"), as presumably they just hide anything they can't supply

I hope so because the Toyo Proxes CF2 is fantastic value for what they are. I don't want to go for a generic brand (they will work in a pinch) but I also don't need high performance tyres.

The Eco Contact 5 is arguably a better tyre but it should be at £90 compared to the £68 of the CF2.

Took a fairly serious paycut in Jan and this cost of living crisis is hurting me a lot.

Can't wait until I can afford a decent car that deserves better tyres. Really keen on getting a GT86 or Scirocco or other 2 door car and keeping my VW up.

Wouldn't want to mix t005s with other tyres personally - in the dry probably not a big deal but in the wet could result in a touch odd handling.

They delivered the tyres today!!! Super happy. They didn't fit them but I think that's a separate service? Either way, I'm happy.

non fitted those tyres are like £53 each. That's the same price as the generic tyres I was quoted.

I can't see it being a problem if the same model tyre is on the same axel?

I have zero issues fitting different tyres on the same axel with a non performance car but an A7 would fall into the performance category. The engines that you can get for the A7 are all very powerful (RS7 is madness).

I'd put stickier tyres on the front and harder tyres on the rear and that would probably be fine. Not saying it's perfect but it would work.

Outside of a racing driver, I doubt anyone could actually notice the difference between two different "decent" tyres front and rear.

As tyres wear different rates front/back (unless you rotate them) you will naturally end up with differing grip levels anyway (and yet no one complains about that?)

On some 4WD vehicles (not sure if this includes the A7's Quattro) you should technically replace all 4 tyres at once anyway, to avoid differences in rolling radius which may adversely affect the 4WD system

New tyres *should* go on the rear, as having less grip at the rear can cause oversteer in e.g. wet road conditions, which is usually more dangerous/difficult to resolve than understeer.

I'm not sure how they'd mix with some other wet weather tyres but the way the t005s behave in wet weather could make for a poor match with just any old tyre. The way they behave on a wet road is very different to a run of the mill summer tyre.

A7 has AWD, not 4WD.

That being said, Audi never drives all 4 wheels equally. The S1 is only AWD in emergency situations and is FWD all other times.

Not sure what the normal mode is for an A7 but I’d doubt it would be 50-50.

Sure, breaking at high speed does cause the rear to step out but I’d argue that it depends on the situation and how much speed and lock you are putting into the corner.

I also wouldn’t be doing high speed in wet conditions but idiots in cars is still a thing.

True, although can apply to both AWD or 4WD

All of the "bigger" Audi's A4 upwards used to be torsen diff with 40:60 front/rear split, as opposed to the smaller ones which use haldex and are FWD unless traction is lost

Correct me if my thought process is flawed but wouldn't the rear tyres being worn out before the front put the same pressure on the diff as putting brand new tyres on the rear and keeping the front tyres?

I'd argue that you'd probably be within the tolerance of the manufacturer of the diff by doing that. All diffs have to have some sort of pressure relief built into the diff as people will do stupid things and you'd have people returning their broken cars in droves if the tolerance was that tight.

My dad told me about old 4WD systems that you would need to 'unwind' because the turning radius between the inside wheels and outside wheels would change during the course of a days driving. You'd need to put the car in reverse and unwind the tension. That was ages ago and using simple 4WD systems that were locked in a 1:1 ratio.

I can see replacing all 4 tyres in that situation just to prevent/reduce the diff tension.
