Michelin Pilot Sport (PS2) 225/40/18 92Y XL (Extra Load) tyre review

Michelin Pilot Sport (PS2) 225/40/18 92Y XL (Extra Load)

(alos can be found here)

Why
We all need tyres, and often we underestimate just how important these 4 small patches are.
I have ran these for 13k miles and Im just about to replace like for like , so I reckon a review was in order.

Considerations for tyres are varied but generally follow these lines :

1. Cost
2. Grip levels wet/dry (which translates to stopping distance and safety!)
3. Availability
4. Brand name 'status'
5. Tread Wear Rate
6. Noise levels
7. Alloy lip protection
8. Speed rating
9. Quality
10. Progressive breakaway

These are all differently 'weighted' by all of us, for me I'm not a rich man, but for me grip (especially wet) ,breakway progression, quality and wear rate are my primary considerations. For each and every person on here I'm sure its different.

I will not discuss 'remoulds' here , but suffice to say I would hope no one on this forum is running them on a GTI, they are wholly inadequate for the car, probably don't have a sufficient speed rating and verge on the downright dangerous.......

Volkswagen fitted various makes of OE tyres to GTI's.
Michelin
Pirelli
Continental

My car (Edition 30) came from the factory fitted with 4 Michelin Pilot Exalto PE2's in 225/40/18 size.
Whilst not a 'bad tyre' the car suffered what I consider to be inappropriate levels of understeer.....

Due to certain circumstances the front tyres were damaged at 12k miles (even though they were barely worn at that mileage!), and replaced with Pilot Sport PS2's
At the same time the car was remapped to ~300bhp and the WALKit fitted.
The steering 'feel' , turn in and stability was transformed. I could attack corners with much more confidence.

These Pilot Sport PS2's have now lasted 13k miles (car now at 25k miles) and are now at the legal limit and are due to be replaced.

The rear original OE supplied exaltos are barely 50% worn after 25k miles !!

After much deliberation and discussion on the forum I narrowed it down to 2 choices

1. Michelin Pilot Sport PS2 (a known quantity)
2. Goodyear Eagle F1 Assymetric (unknown for the GTI but won reviews and I have had VERY good experiences with GSD3 pattern F1's on previous cars)

In the end I bought option 1 which I'll explain why in the summary......

Heres some useful data (they are all links...)

Sourcing

This time I have chosen to use a mobile fitting service called Event Tyres
Order the tyres online , select a date , they then phone you back (very quickly) and confirm the time/date etc.
No money is required until they are fitted.
So far the experience has been top notch.
Just make sure you order the CORRECT tyres

(you dont want MO type , you do want XL rating)

I got a £10 voucher code from http://twitter.com/event_tyres as well.

(Of note I also referenced
http://www.camskill.co.uk/products.php?plid=m4b0s134p11466 which are generally cheapest at £128 each)

From event tyres it was £290 for 2 incl fitting (- £10) voucher = £280
Not the cheapest but suits me.

(Costco also do tyre deals which is definitely worth checking as they are much cheaper... eh SteveP )


Fitting

TODO : to be completed once event tyres do there stuff!

Other options to consider

Goodyear Eagle F1 Assymetric
Pirelli PZero
Yokohama parada 2
Continental Sport Contact

Read the reviews , check the forums (for the exact tyre size you plan to fit) and decide yourself

Plus Points

hot weather : good strong grip , nice feel , progressive breakaway, easily recoverable, nice turn in feedback. no impression of weak sidewalls at all
cold weather : as above + good stability , never once aquaplaned.

100% tread : no 'bedding in' phase required , great from mile 0
50% tread : still performing great, no change in wet or dry from 100% tread

10% tread (legal limit) : amazing for a nearly bald tyre! still manage to shift some water, in general driving seem normal, however once the (lower) limit is reached the progression is swift into terminal understeer. To be fair I have taken these tyres way past the point of tread depth where I would normally change. But they perform so well.

limited road noise, probably got slightly worse once past 75% worn (25% remaining)

on the track : not tested so I cant comment in this scenario. Reckon they should perform well as long as they dont overheat and tyre pressures are kept stable
up the drag strip : rubbish driver on a cold day = poor results lol, not the tyres fault

Minus Points
The biggest minus by far with these is the COST , at least 10% (often more) expensive than Goodyears.
not a big rim protector either

Summary

I chose these again because based on the mileage (13k) , the fact theres no scrubbing in mileage (500 miles for the F1's) , no massive reduction in performance at the legal tread depth (that F1's do tend to have) , these factors balance out the increased cost.
I just couldnt risk putting Goodyears on. Maybe next time I will, but for now nope...

As with all tyres , check and experiment with your tyre pressures , it can and does make a huge difference

As a rough guesstimate the tyres have worn 8mm (9.5mm - 1.5mm) in 13,000 miles = 0.6 mm per 1,000 miles wear rate
At a cost of £145 , they have cost just over 1p per mile (per tyre)

Exaltos are a good compromise if cost/wear rate comes above outright grip as a priority.

Choose you tyres carefully but check out the reviews and see how much the stopping distances vary between tyres!
They may just save your live one day , where a few extra horsepower from that air filter etc wont. dont scrimp

In summary I highly recommend these for the Golf GTI

replacement OEM Diverter Valve Edition 30

All early revisions on the TFSI engine seem to leak or fail eventually.
VW seem to have finally sorted this on the TSI by removing the flexible diaphragm.
This apparently also can be retrofitted to the TFSI engine ;-)

TSI (rev D) VAG OEM DV [part number 06H 145 710 D]

Ive noted it here as I reckon mines on the way out.......(or its the PCV!)
