**Unofficial Tyre Thread**

I've just ordered myself a set of PS4's in 225/40/18 for my A3, will get them on before I go to France. Will be glad to replace the awful Bridgestones that came on it, they are so damn noisy, and I'm not keen on how they feel.
 
Kumho Ecsta ku39? Any opinions? Are they a good brand/tyre?

I was opting for rs3's again, but the price is relatively the same for either.
 
PS4's are on :)

So these are better than Pilot SuperSports then?

If I've understood correctly:
PS2: Excellent but ancient
PS3: ****
PS4: Excellent; comparable to CS6 and F1A3.

I thought the Ps3 was a good tyre? I have them on my other car and can't fault them anyway. They take 360bhp in a front wheel drive pretty well anyway!

It's not a bad tyre its just a badly named tyre. It replaced the mid range Pilot Exalto 2, not the UHP Pilot Sport 2. So people logically assume it's a UHP tyre when it isn't.

Further confused by the fact the new PS4 *is* once again a UHP tyre.
 
Newbie question, had my car serviced a few weeks back (Fiesta 1.0T) with Premium Contact 2s on front and rear. I have done 15K miles so far in 1 year of ownership and mainly motorway driving.

I check my tyre pressures cold every week and make sure they are at the recommended pressures (they were spot on as measured by myself and the garage at 31 PSI F and 26 PSI rear, but I'm curious as to the wear pattern or if there's anything seemingly odd.

I'm not sure how much wear discrepancy points to pressure issues or just simply fact of life wear differences due to driving style, roads etc.

Fronts shows as Inner | Mid | Outer

Rears shows as Inner | Mid | Outer

R 6.2 | 6.1 | 6.4
L 6.4 | 6.5 | 6

Would say the fronts are probably overinflated.

Does the sticker on the door list two different pressures (e.g. one for 1-3 passengers, and one for full load)?

At a guess you are running at the higher one - If so try running at the lower pressure, or somewhere in between.

Tyre pressures aren't an exact science - as long as you don't go over the tyre manufacturers maximum (printed on the tyre usually), and don't go more than a couple of psi below the car manufacturers recommendations shouldn't have an issue.

Different tyres wear differently, and are constructed differently, so may need slightly different tyre pressures to get best performance or longevity.

The 31PSI is the recommended pressure for 1-3 people and no load. But I guess I'm running 1 person and never any load means 31 PSI might be a tad too high?

Personally would have no issue dropping them to 29 or 30 for a few months, to even the wear out a little (Just remember to top them up if you do load on luggage or passengers)

Does seem a bit odd though.

Is it possible they may have overinflated at some point in the past?
 
Bit of a longwinded post this, apologies in advance.

At Christmas last year, my Dad was driving my car whilst I was abroad and picked up a puncture. He then replaced the punctured tire and the other front tyre, but he did so with super cheap, £27 each Triple-A tyres. They've actually been flawless since then, and I haven't noticed a difference between those and the Dunlop winter tyres (forgot exact model) I had on before the puncture in terms of grip. The rears are now due to be replaced, and I've done enough miles that the owners manual suggests rotating tyres.

Now that brings me to my question, do I replace the rears (going with Dunlop Sport BluResponse) and then leave the better gripping tyre on the rear, or do I replace the rears and then rotate the tyres - leaving the noname tyres on the rear axle, and ignoring the tyre rotation.

EDIT: Should mention that I can't replace all four atm, but yes that would be the best solution!

Quick question, but with the AS3's I've had on for a few weeks now, I had my service last week and as part of the visual health check, they've noted that all my tyres are currently 5-7-5 in terms of tread depth.

Why are they 5 on the outside edge? They've done less than 300 miles since new so I doubt I've lost 3mm in that time, is that an error on their part or do they just start with less depth on the outside edges

Probably measured incorrectly, as tread patterns tend to differ between the middle and edges.
