Standard 17 Elite alloys on 3.2 Elite with LPG. GY F1 assym 2 XL

Cannot really complain except for the fact that they are quite noisy, esp over poorer surfaces. About 6k on them so far. No experience in the size you ask for though, so may be useless to you.

Could you post the size, speed and load ratings D, if you get a mo.

17" std elite alloys, so 235/45/17, XL 97 Y.

Edit: To confuse things, there is a F1 assym and a F1 assym 2 (i.e. 2 being the newer version).

Bit late to this but I'm a Goodyear groupie and have been for years on large (relatively) powerfull cars such as omega, senator, and Beemer 5 series through past work.

I continued using Goodyear on my own cars including Carlton gsi, pfl mv6 (eagle) and fl 3.2 estate (f1 assym and assym 2).

The FL runs 235/45/17 and 97 or 98 extra load (will check in the morning if you wish) as well as bilstein B4 and eibach springs all round. WIM settings will be out now due to wear and the car now tramlines a wee bit. When all as new and sharp it was, well, new and sharp. Handled well, wet or dry, predictable and able to be played with on bends and roundabouts as and when.

As I have edged closer to pipe and slippers over the past 6 years I have realised how lucky i have been in driving terms over the past 25 or so years I have resisted the temptation to put the car sideways at every opperchancity and now like the knowledge that the tyres are grippy and sure footed 99.5% of the time.

Dunno if that helps of hinders your choice TB but I know what I like and I like knowing that the tyres are predi table and not liable to bite me unexpectedly if I get too keen.

They are softish though but I consider them as consumables. Anywhere between 7-10 k is fine by me....

Best advice Jaime - go forward with a tyre that works ok on Omegas, preferably on both 16" & 17" rims (in the absence of +ve data on 18"s).  Aim for 95+ load rating and be prepared to "play about" with tyre pressures.

This is "damage limitation"

My feelings exactly at the moment, due to needing to replace at least 2 of the SC5s. Long term, I'd like to try to understand why, if we can, but my immediate issue is what to do now. Hence the thread asking about specific tyres I'm interested in

But ffs why is the Omega so borderline with tyres?  Many, many owners just go to their local tyre centre and buy "reasonably priced" tyres and don't experience issues with wandering.  Accept that SC5s dodgy on Omegas, but don't accept that the majority of other makes also cause wandering on Omegas.  Don't see or hear of owners of other make cars having a big issue with wandering.  Maybe certain people are searching for the "holy grail"   Fraid its becoming obsessive now.

The Omega does seem prone/more suseptical to lack of stability in a straight line than any other vehicle I've owned or been responsible for. Note, due to various definitions of what people call tramline, I'll just say, I want the car to go straight, particularly on roads that do not look to have a poor surface.

The "Holy Grail" level I'm looking for I eluded to in the "Relaxing commute" thread - having a car that is a relaxing cruiser, easy and effortless to drive. Yet has the capability when the mood takes me. Sport Maxx TT (and SP9000 before it, though not at the same level of grip, but was slightly better wearing) shows this does not have to be mutually exclusive.

I have driven 3 Omegas (that it can be shown the chassis was fine) that I thought suffered straight line stability issues so bad that I thought it bordered on the dangerous:
Gayboy's "Gay" car with Falken 912 at Asheridge meet, I thought was so dangerous, I refused to go more than about half a mile - it was an uneven country road, but even so, every time a car came the other way, I was fully clenched trying to get it between the verge and the oncoming car.
My TBE with SC5s
My Silver Bullet with TBE's SC5s on

Both of use have made these expensive mistakes, based on recommendations from people who have used them on other cars, tyre reviews, etc etc.

Neither of us want to see anyone else make similar, expensive, potentially dangerous mistakes. And from a slightly selfish viewpoint, I don't want to make another as well, even if I could afford to.


Hope that clarifies where I'm coming from, and why sometimes frustration creeps out

As previously said .. offer is there for you to try the eagles .. just have to work out the methodology ....

Thanks H21, thats perfect feedback.

Did you ever try them on those Irmscher wheels you had, they were 18s IIRC?

[hotel21]

Nope, never fitted the irmscher 18's. they are still in my garage. You want a spare set??

I'd say that there are certain tyres that do make an Omega pretty unsafe. No experience of SC5s but Gixer's old Falkens were scary. It's not a case of people becoming obsessive, IMHO.

You only have to look at the suspension setup on the Omega. The most basic mcpherson strut setup on the front, steering axis behind the wheel, recirculating ball box instead of a rack, all suspended on really sloppy bushes to try and make it comfortable yet taking the loads consistent with being fitted to a 1.8 tonne car.

It's all going to make the setup of the car sensitive to any forces exerted on the suspension by the tyres, so if you have a tyre that tries to tug the suspension out of true with every undulation in the road surface, it will deflect the suspension on an Omega whereas in other cars, the suspension might resist to a better degree. Put a more "well-behaved" tyre on and it'll be fine.

You only have to look at the setups on other "large comfortable saloons" to see what lengths other manufacturers have gone to. The Omega is nice and simple to work on in comparison, but I believe that's where the sensitivity to tyre characteristics comes in.

Based on some cars I've driven, it's clear to me that a lot of drivers aren't that critical of this behaviour and tend to drive around issues in car setup and, when the behaviour or applying constant corrections eventually becomes "programmed", become ignorant of the issues, rather than analyse them and try to resolve them. A case in point being that before mine was properly sorted after poly bushing it, mrs. KW didn't like driving it yet couldn't put a finger on why. "It's too big", etc. After it was properly sorted and I explained what I considered had been improved, she agreed, and now says it's much less tiring to drive. It's easy to put where you want it on the road and thus no longer "too big" and also more forgiving of her "one hand on the wheel, the other rummaging in handbag, etc." driving style.

Wrong offset for me iirc. More interested if you'd tried 18" GY F1

[feeutfo]

Lets assume that load rating is key for just a second. Yet to prove it but will we ever? But just for a second.

In the same way that camber is key to inner edge tyre wear, we have established that even the least aggressive camber setting specified by Vauxhall is still going to give excessive tyre wear.

With that in mind, should we trust them on load rating as well? Or, giving vx the benefit, maybe the load ratings where correct when tested and gave stability but now non of those tyres are available and we have to move on. Only to find that one makers load rating is quite differant to another's.

The more I look at it, thanks to members patience, the more I feel we would see less stability problems with load ratings above 96. But then we are the only ones with facility to test that theory.


....ultimately I think we are a victim of Vauxhall testing, or lack of. Tbh.

I might be interested in the future

[05omegav6]

TB if you can wait 10 days or so I will be taking my car to WIM
Got bushes to change first, but needs doing sooner than later as inner edge on the fronts are already wearing

As Buzby said, 'it's good to talk'. Or was that Bee Tee?

Don't hang on to them for my benefit as lots of other things have to fall into line first but I'll be in touch to see if they're still there once all the ducks are lined up

I don't think Enduros are for me. Not that I've tried them. Maybe for Mrs TB at some stage in the future.

I have a theory that I overdrove the SC5s. I cannot believe any manufacturer can supply tyres that are so woefully bad.

Although, that said, they are supposed to be high performance tyres, so should be able to have some abuse (and they haven't had much TBH), and we've seen similar with Falkens.
