New tyres tomorrow

[MikeyH]

Just booked in with Kwikfit for tomorrow to have 2 front Goodyear Eagle Asy 6 tyres. Good price at the moment if you buy 2. £196.30. They do a free alignment check but might give that a miss :wink: Been a noise coming from the front tyre for a while and getting louder and they are 8 years old!! So, overdue but have been resisting as they have reasonable tread still. I ran my hand around the back of the tyre after watching some youtube videos about 'cupping' (not that sort) and looked with a torch this morning and It seems they are 'cupped'. If the noise is still there it will be wheel bearings I suppose.

Had Eagle F1s on my E89, I thought they were really good, had PZeros on previously, they were also good but just didn't seem to last long.

I've had avon zz5 s on the car since I bought it almost 3 years ago but they are now 8 years old. I replaced the rears last year with the Asy 6, the trouble is the Avons will not wear out and I keep reading that old tyres are not good. So this is the time. I'm hoping that the steering will calm down a bit and be less twitchy with new tyres.

I hope so, I have never felt that comfortable going into a bend with the Z4.

Well it should corner very nicely…assuming it’s got good rubber…if it’s still not happy maybe time to look at west n tear on bushes / geometry?

Yes might be a good idea, I'll see how it goes. It's a shame there isn't a decent BMW indi down this way.

Boy O boy. Well the new tyres are grrrreat. Got rid of the annoying bomp, bomp noise and the front doesn't dart about anymore. There is a stretch of 40 mph dual carriageway were the car has always pulled left and then right. Not anymore. Went for a drive on a twisty bit of road near me and feels so much safer and sure footed. Got them online from Kwikfit (10% off for 2 at the moment) and had them fitted at the Torquay branch, what a nice place to go to. Not had such good and friendly service from a tyre place for years, so different from the awful service at another national tyre company in Newton Abbot when I bought the rears last year. Only odd thing is why do they always pump the tyres up so high, 36 psi and 38 psi the other side. Guess where I'll be buying my tyres from now on.

Good news on an E85 32/34 would be my suggestion..

Always strange how new decent tyres improves handling?

I've got them at 31/33 at the moment, I'll give yours a go though, thank you

So, any ideas about this please. The new tyres for the front bought from Kwikfit Saturday have 7mm of tread (my gauge) and have a red or green (sorry colour blind) line around them. The ones on the rear bought from the another national tyre company this year in February only have 5mm of tread (my gauge) after 4,190 miles of careful driving. And I don't remember seeing a line around them and they are 1yr 5 months old now. This means they would have been 11 months old when I bought them. So 2mm of wear in 6 months, does this seem feasible or have I been ripped off by the other national tyre company? My wife is 99% of the time in the car with me and doesn't like me 'wanging' around corners. Both times I bought the tyres on line and had them fitted at the companies local tyre place. Your thoughts would be gratefully received although there is nothing I can now do about this.

Are the front and rears same sizes, same makes etc?

Rears wear faster than fronts by usually 2 or 3 times..

Same make Goodyear Asy 6 , front 225/40/18 , Rear 245/40/18. The fronts were 8 yrs 5 months old and had about 4 mm of tread but they must have been way past their best The rears were very close to the depth markers when I swapped them and the fronts still had a lot of tread left so that would make sense what you say is correct. From the paperwork I received when I picked up the car it showed that all 4 where bought at the same time. I haven't owned a rear drive car for a very long time and it's usually the fronts that go first. Thank you, made me feel a little better.

Front / rear tyre wear rates vary enormously with type of driver, locations, type of driving, power, weight etc..

If you drive reasonably hard including going around bends at pace then you should get even tyre wear across the tread but rears will go down 2-3 times to fronts ..with a rear wheel front engined car..

If you point and squirt then uneven tyre wear ensues but front / rear ratio will still be 1-3 ratio ..

Thank you B21, 2mm in 6 months seems a lot, made me wonder that was all

So B21, after your suggestion re 32/34 I gave it a try, didn’t seem that different TBH but yesterday I put them back to 31/33 and the tramlining came back. So today went back to 32/34 and better again, feels much better and more predictable in corners. How such a small amount can make a difference I haven’t a clue. Perhaps it’s a perceived thing but it definitely does feel better.

It's called 'the placebo effect'.

The reason why people on car forums buy £500 brake pads on the recommendation of others, then swear they are the best. Works with tyres aswell!

Sorry Mikey, no offence intended, but 1 psi(g) difference in a tyre will not make any noticeable physical difference. For a start; your gauge, unless it a very expensive calibrated one, will have an allowance for error more than that. The ambient conditions can make more difference to a tyre's pressure than 1 psi(g). Much more.

There is nearly as much bollox written on car forums as there is in the real world these days

 

[MikeyH]

Yes, I did suspect that was maybe the case. But it does seem better :?

Are those tyre pressures you are talking about meant for runflat tyres? They seem quite low to me, I'm running more like 36 / 39(40), non runflats of course.
I have just removed summer tyres for the winter and they don't seem worth putting up again, too worn. GY Asy6's with ~12.400 miles (2 seasons), sporty driving. I noticed uneven wear on the rears, the inner side is worn to the indicators while the outer side is still good. The whole wear is linear from side to side. I suspect this might be normal due to how the rear wheel tracking on the e85 is set, but is it true? I had the alignment done this year.
The fronts have more even wear, worn almost to the indicators.
But the tramlining is quite noticeable on this car.

My experience from e39 5 series is the rear tyres wear out in 1,5 - 2 seasons, the fronts usually last 3 seasons. 1 season being 6200-8700 miles.
The wear on the rears is even, not like on e85. Tyre pressure 37 / 40(41). Sporty driving. I have the staggered setup, 18".
I have tried quite a variety of tyre brands on the e39, but the wears were very alike overall.
No tramlining at all.
