Having finally found some spare time to have a detailed read of the test conducted on 235/40 x 18" tyres, I was rather surprised at some of the results.

The usual riders apply: the tests are valid on the day, under the conditions and with the car used (in this case a Commodore).

I have divided each of the tests conducted into individual charts which are posted in separate threads below.

On a side note: the author of the test stated that there were no really bad tyres in the test - a conclusion I would take issue with based on the results shown below. You be the judge.

Cheers

Test 1 - Wet Weather Braking Performance

Conducted at the DECA skid pan the test simply used ABS activated braking from 80 km/h.
The Falken was the best performing tyre, stopping in (a very good) 32.4 metres while at the other end of the scale the Toyo Proxes could only manage a pitiful 44.0 metre stop. Put into persepctive that is a difference of 11.6 metres or 38.6 foot for us old timers - in simple language about 2.8 car lengths. That is the difference between a miss and a VERY big bingle. I'll do the math later to work out what speed impact the Toyo equipped car would have at the 34 metre mark but it's likely to be upwards of 65 km/h.

The two local OEMs (Dunlop and Bridgestone) didn't exactly crown themselves with glory, finishing 4th and 7th respectively (from 8 contenders) which is a bit odd given that the Bridgestone is the OEM trye for the Commodore.

Dry Weather Braking Performance

Also conducted at DECA this test was the same as the previous one but with the speed increased to 100 km/h.

This time the gap between best and worst is only 8.4 metres or 28 feet or 1.8 car lengths but that's still enough of a difference between "missed" and "faaaaaaaaaaaaark".

Once again the Falkens take the honours with a distance of 37.7 metres while the Dunlops take the wooden spoon at 46.1 metres. The OEM Bridgestones garnered themselves another 7th place showing to at least be consistently poor brakers.

Let's next look at the combined results:

Combined Results

There isn't much doubt when it comes to braking the Falken is a fair bit above the rest of this pack. I've used the really simple measure of combined distance to rank the tyres over the two tests and included that in the attached graph. It may not be absolutely the best criteria but it is at least a measure.

On this basis the winners (and losers) are:

Falken GRB FK451 70.1
Hankook Ventus Sport K104 74.1
Pirelli P Zero Nero 77.4
Goodyear Eagle F1 79.3
Michelin Pilot Sport 82.0
Dunlop SP Sport 9000 83.9
Toyo Proxes T1-S 84.3
Bridgestone Potenza RE040 85.8

I will look at the lap and short course times a little later and see how this impacts on the end results.

Cheers
Russ

The pennys dropped at last, the sp9000 and the bridgestones are used by ford and holden because they have done a deal with them, not because they are the best tyre for that car! they are the ones thet meet the price barrier that all, so next time your due for tyers go for something else. I think the SP9000 are not bad but there is better for the same price...

I'm very surprised that the Hankooks are up there. Maybe I've been out of the loop, but I always thought they were fairly bodge tyres. Might have to consider them next time round !

I would have liked to have seen the kumo ecsta 512s in there but from that evidence (braking only, I would say it is not very conclusive) you would have to go with the falkens and avoid the sp9000s like the proverbial plague.

A car travelling at 60 km/h in dry conditions takes about 46 metres to stop. A car travelling at 72 km/h needs an extra 16 metres.
Off topic I know, but I could not resist to point out.

I got the K104 in 235/40/18 fitted on the XR8 about 6 months ago, and I'm very pleased with them. A friend has the Falken 451 on his car (same car and tyre size) which are a lot more noisy in cabin, especially on old surfaces on highways. The K104 did very well in the 235/45/17 test aswell. I'm waiting to see what the thread wearout will be like as this is one test they cannot do for obvious reasons, other than that, the K104's get 9/10 from me.

They're probably taking into account reaction time, but its still BS

Guys, with all the extra power iv gained from my beast i was finding it very hard to get traction so i decided on changing the tyres on the GT-P. i didnt like the dunlops due to the fact that they had to many grooves in order to twist, yes they are great in the wet but i dont drive the thing hard in the wet as its only stupid. i ended up fitting FALKEN ST115's in 245-40-18 front and 265-35-18 rear and i will say that the traction is truly unbeleivable compaired to before especially once they get some heat into them.i also found they are a lot quieter as well compaired to the dunlops, and yes i did fit the 265's on the standard rims with no trouble.

Firstly im surprised that the Dunlops fared so badly,i would certainly reconsider buying new Dunlops at $550 a tyre.
Secondly i would have liked to see the results from Yokohama's which are supposed to be a good tyre at approx $440 and
Thirdly to BOSSGT what price on the Falkens the 245/40/18 and 265/35/18
Cheers John

gtp320 We used Yokahama AVSs on the GT in the Dutton Rally and the improvment was nothing short of fantastic!!!

I'm using these Falkens as well. AU1 XR6 HP, 235/45x17 on AU2 XR rims. I don't do any track work or anything like that, just daily driving. I've done 25,000kms on them and these are my thoughts on this tyre.

They are a very consistent tyre in that the handling feels the same as when they were new. They are quiet and feel solid and reassuring but to me they don't have quite as much feedback through the steering as my previous set. There's bugger all in it so this can't really be called a criticisim but it's an observation I've made. In the wet they are good. They seem to drain the water pretty well, takes plenty of surface water before they aquaplane and are very predictable in their handling.

At 25,000kms they still have heaps of tread. They'll get to 40,000kms no probs and may even get 50,000kms out of them which is exceptional in a performance tyre. I got them in a deal with the wheels but the price was around the $270-$280 mark. At that price there may be others that may handle a little sharper but may not get the mileage out of them. These tyres are a very good compromise.

I'd get these again but I could be tempted with a competing tyre if the price was right.
