I use this size asym 2 f1 .. if you dont care about uk insurance issues its ok..


however, if you will let the car stay for long periods , dont forget to increase the pressure
like 10 psi above normal..

235/45/17 is the official 17 inch size. You may run into insurance problems using narrower variants. Also, the rolling radius is wrong, buggering up speedo etc.

I have used GY F1 Asym2's for about 18 months on Omegas, but will not buy any more. Relatively poor life combined with the better end of mid-range grip make it quite an expensive tyre offering very little for me.

A good tyre, but a "Max performance" summer tyre it's most certainly is not.

 In terms of performance....Good yes, great no. Sc3 and especially RT have a fair dollop more grip.


Although, could serve some people well at that price. I suppose.

interestingly, I start to think temperature difference between UK and my country is really effective..


because never seen abs working on eagle f1s  and also never seen they are insufficient in corners despite the mad speeds I have tried ???


but I think also winter time temperatures are effective that some edge users are complaining about grip.. but that tyre not designed for that time :-\

I find these tyres excellent in 235/45/17 form. :y

I'm not sure what difference a 225 tyre as opposed to a 235 tyre would make. Little, I imagine.

Tyre wear isn't great though. After 9500 miles my rears are pretty close to the wear markers. :'(

Final word. At £70 a pop what's the worst that can happen? .....even  Wanli Ditchfinders come in at close to £60 a corner and the rears were fooked after 5000 miles.

But is the Omega a "Max performance summer car"?.......Not really, Mr Gixer. I use my Veyron as a maximum performance summer car. Honest. ::) ::) ;)

On the subject of tyres...  my new CDX has Primewell PZ900's on it and they're surprisingly good, not to mention cheap :)

lots of reviews about road noise, but they're very quiet on the omega.

Nah, you're just not trying hard enough. If you can't get the ABS to fire with those tyres (235 width), your brakes need fixing ;)

I would certainly buy these tyres again.

If memory serves I paid something like £94 a corner for 235/45/17 from 'love tyres'

My local Vauxhall dealer fitted them for £10 plus VAT each.........total £48.

Interesting isn't it. Person A has tyre Z, and considers it the best ever fitted on the car, there for, it must be the best tyre in the world and there can't be anything else worth considering.

Right? :) Is that really what we're saying? :)

Of course it depends on the individuals needs. And experience.


A good tyre means many things to many differant people. If I recommended sc3 over f1 you'd complain of noise. If I recommended rt over sc3 you'd complain of wear. If we then went back to f1 you'd say where's the grip gone?

But as the advert mentions specifically to grip levels. I can definately tell you there are better available. As cem says you mostly know those tyres by now. Dunlop rt and ac3 mo. BOTH of these have more grip.

... However they do have other downside, relatively speaking.

Anyway. Point is, they can't be maximum grip tyres if there's tyres with more grip available. Good tyres all things considered but there's better available and the ad is slightly misleading.

You can do a hell of a lot worse than f1's too of course. :)

The perfect tyre.

Free.

Never looses grip ever.

Never wears out.

Always gives bullit straight stability.


Until then there will always be questions.



.....Or somebody implements concrete tyres and rubber roads. ;D

Sc3 are alleged to be superceded by sc5 so no tester will get sc3 off conti without paying for them. Hence, not in tests.

They are still available though. .....As are sc2 in some sizes....well I guess so as I keep seeing them new on other cars.

I think it probably needs to be stated that if you overdrive a reasonably good tyre, the wear is horrific. This is what I've found with SC5 (which actually wasn't that grippy at all) and F1s.

An Autogrip will never wear out. You will die first, in a hedge, alone, in the rain.

But if over driven the structural strength of the tyre, then yes, that I can understand, if that's possiible, which I believe it is rightly or wrongly.

I need to whip them off before using it, so can check then.  I think they were fitted this year, prob Feb time, so would imagine date code back end of 2013.

That be why they're fooked... Given the speeds you drive it at, they should be at fully loaded pressure. In fact I am surprised Chrisgixer hasn't suffered similar damage, for the same reason, although I think you might actually work the car harder...

Effectively you have overloaded the tyres by running underinflated. Were they extra load or standard 93s?
Title: Re: Possible cheap 17" tyres deal?
Post by: chrisgixer on 28 September 2014, 11:25:29
Other way round Al. A tyre works at an optimum temp. Which equates to a given psi once hot.

So of working the tyre hard, you generate a good deal more heat and the pressure goes up. If the pressure goes up too high, the grip tails off.

Ask any track addict. ;)

....although, it depends on the tyre and how hard the driver pushes to achieve x amount of heat and therefor pressure.

If adding load to the car however then yes wack the pressure up.

Also assumes tyres are of correct load rating to start with. Imo omega minimum load rating for tyres is too low.


....for.....enthusiastic driving anyway. :-X

The point being... to dismiss an otherwise perfectly reasonable tyre brand because it has been abused and not stood upto that abuse is somewhat churlish...

Needs further nvestigation, but I doubt TB is doing anything different than on any other tyre he's had.

between all these searches for reason I highly doubt daily use performance tyres are designed for track type use..


track tyres are (for dry) have a harder compound and will grip when its hot.. but will be very noisy when cold..


when buying those tyres I compare both dunlops and f1s.. dunlops were harder which I didnt prefer..


but Al has right. for performance use the pressures must be higher for the tyre to keep its shape on fast cornering , fast braking etc regardless of weight.. 32 psi is too low for omegs for high speed use




also I discovered that when accelerating I need higher pressures for clit which now I use 35 psi otherwise it cant grip when turbo kicks in

At the very least the load rating in those particular tyres is off :-\

clit is front wheel drive cem. Omega is rear wheel drive.


The rear tyres have a lower pressure on front wheel drive to replace the amount or "work" missing from the drive of the engine.

Omega has more balanced psi all round due to weight of the engine and steering at the front, versus drive at the rear.

If asking front wheels to drive and steer at the same pressure they will over heat. Plus an increase in 3 or 4 psi won't affect the structure.




.....however, if running lower than desired pressure, that achieves the desired temp, then it will over heat.


I wonder if pressures have gone unchecked for some time, and gone under inflated. Or the load rating is too low for the car. ( hasty edit,  or too low for the car  when driven by TB...?)

irrelevant with the subject..


if you want grip you must have pressure to keep shape..  deforming shape tyre means less surface..  and its critical in cornering

OK, to answer all the Q's.

Datestamp 2313, so little over a year since manufacture.

Pressure, 32 PSI. They have been run harder when carrying load, and are noticeably skittish when run hard with no load, as are all tyres. Looking at wear pattern (these have been on the rear), this is still overinflated.

These are driven less hard than most tyres I've had due to lack of grip and a desire not to end up on a kerb going around Milton Keynes.

There does look to be a brown discolouration around the area where the tread meets the sidewall, maybe a telltale of overheating? If they have overheated, given the very limited number of times I've pushed these tyres, I suggest they are unsuitable for the Omega.

94Y, GM state 93

The brown(or sometimes blue on softer compounds!!!! ;) ) is exposed worn tread that's unused.

So that would fit with enthusiastic driving, by you for example. Followed by more sedate driving for some time, by Mrs TB for example, where the exposed worn tread has been exposed to the elements. Sidewalls and other parts of the tyre that are exposed but not brown, and not in contact with the road will still have release agent on intact.


Brown is sometimes visible on sidewalls that have been scuffed on a kerb for example.

Personally I won't fit anything less than 97 load since the F f fer FALKEN disaster. Or at least the highest load available by that manufacturer.

Every Dunlop I've had has been 94 or 95 (depending on model).  Only ever seen this cracking on those Heinz 57 from your car, if you recall those?

If they have been on the rears and driven hard from a standing start whilst soft, then could it be torque destroying the insides of the sidewalls :-\

Be interesting to see what state the inside of the tyres looks like...

How does the sidewall construction compare between the Dunlop TT/RT and the Goodyears :-\ that might answer the conundrum...

My average speed over the last 500 miles has once again dropped to almost 20mph, due to breakless morons not prepared to get anywhere near a speed limit.

The Dunlop And Goodyear web sites are almost identicle. As are the sizes available, and the suppliers. They are almost one and the same. Branding and models are differant obviously, but they do share technologies and resources. ....last I looked anyway.

Differant set up in the states iirc.

Never taken below 30 psi, and defo been at 32 since they've been on the front.

Stress? You know the answer to that ;D

Nah. I had 3 tyres that I knew needed almost daily checking - one has been repaired (though back to be rebalanced), and the other 2 are on the battlebus.

Because of these going down, all tyres have been checked at least twice a week since I got the bus of many battles, in Feb ;)

Ah, pre battlebus, no issues with tyres, so only checked fortnightly or so :)

RTs ordered, should be ready tomorrow.
