Bought some pilot sports about 7000 miles ago.

First impression was good. Cured the tramlining, suspected it was down to softer tyre walls.

Now I am certain.

Even though the tyres have good (ish) tread on them, the sidewalls have worn down to the canvas.

Now, its not down to geo, thats fine, has been checked and the original Bridgestones wore even across the whole tyre.

These tyres seem too soft for the weight of a newage STi.

oh hum, back to bridgestones unless anyone has any ideas ?

 

The Pilot Sport(PS1's?) were very poor on a Scoob but the Pilot sport 2's were better by Far IIRC The were dual compound giving a harder outside edge.

Bridgestones RE040 (fitted to newage 01-05)are very hard walled, just watch a trye fitter strugle to change a Bridestone compared to a goodyear etc.

IMHO Tramling is a trait of hard sidewalls but if they're too soft like the PS1's they won't take the stick Might be worth trying Bridgestones RE050's

If you want stiffer side walls then go with yokohama's, just don't expect a long life expectancy.

Otherwise Bridgestones, F1's or Toyo's.

Try running more air. It seems people are tending to run their tyres too soft for standard road tyres at the moment as they're not compensating for the fact that when you're checking pressures the tyres need to be cold. It only takes around a couple of miles of driving to warm up air inside the tyres and that can increase pressure 2 - 4 psi. All manufacturer's guidelines regarding tyre pressure will be from cold so you can see there can be a tendancy to run 2 - 4 psi too soft if you're making adjustments to a warm tyre.

To be sure it's worth investing in a manual pressure guage and small compressor that can work off mains or off the car.

 

You can get differnt loadings on the tyres you know. What have you got. I'm currently running PS2's with 92Y loading.
Only just found out that Prodrive recommend 95Y. Next set will be 95Y with PS2's
I'm not experiencing anything wrong with my current tyres though, and they've been on since last August.

 

I've got FALKENS on mine and they come very highly rated - replaced my Michellin Pilot Sports which had covered about 25,000miles.

Hopefully the Falkens will give me sensible mileage like the michellins did!!

Hum, my PS's are 91Y.

However, got some bridgstone RE050A's selected by advice given (thanks people, don't you love scoobynet) and the scientific method of squeezing the tyre wall . The RE050's tyre walls are SO much stiffer than my PS's and all the other tyres in the suppliers stock.

However, these are also rated 91Y , but don't roll onto the tyre wall on roundabouts. No tramlining yet but the OEM RE070's did not for the first 3000 miles. Only time will tell.

 

Just fitted 4 new 225/40/ZR18 Falkens directed from their website £255 delivered

25,000 miles from a set of tyres??? How in ****s name did you manage that?

 

I do NOT drive around like my **** is on fire, thats why!!

It's also the way I got 66,000miles out of my front barke pads and discs - the rears are still going strong, at 68,000miles

Pete

 

No ofcourse not, but it does sound like you drive around like your pension book is about to expire..

I dont think its anything to be proud of, its like bragging about having the same pair of jeans for the last 10 years.

 

I looked at my revs a while back and just monitored how I drive ..... in a week the engine was taken over 3000RPM on about one occassion.

I just cannot see what the point is of doing more than 3000RPM at any point on an everyday journey???

Now, once in a while, I will stretch her legs - but, only after thoroughly warmed up over about 10 miles - and only for short spells.

No need to drive around like a frigging 14 year old on a Playstation!

Pete

 

Driving around in high gears doesnt help either, it puts loads of strain on the engine.

You need a diesel.

 

Ok, the RE050A's are now scrubbed a bit.

They do not roll over at all and general turn in is good. Grip seems fine

The steering has reganed some of the vaugness about dead center and some tramlining, only time will tell if it gets as bad as the RE070's

BTW, I do drive faster than PS, but not like a lunatic. Very suprised that the fronts wore like this. The original Bridgestones lasted about 12,000-14,000 miles and thats when it was just a weekend car.

 

i had similar problems with toyo t1-s's - caused by under infaltion

 

under in-faltion , hum sounds worrying.

They were inflated to the reccomended pressure, or slightly over.

Toooooooooooooooo soft
