Hi everyone, had a accident in my 3.2 MV6 at the weekend. Not very happy but hay i am still alive so nothing to complain about. The car just span out of control and i am convinced that the Tyres are the problem. So i am not going to mess about!!! i want to order 4 good tyres for the car. it is 2001 and i was just wondering if anyone out there could help me with the make i should go with. Money is always hard to come by but am willing to invest to be safe. tyres are 235/45 17 
The Tunster may be a little....abrupt? at times. But tbh he has a point. With traction control on the omega it is almost impossible, well, fairly difficult to spin. In fact with tc enabled as it is by default, unless you press the button, it is a real fun killer. But more importantly it works very well if you get caught out. It has kept me out of the ditch on icey un salted roads at least twice iirc.
I really was not expecting the car to slide at such a slow speed following another car, so was not ready for it at all. Finger and thumb on the wheel elbow on the sil. Slide, tc cut in, grip, wow sh1t, all over before i knew what happened almost.
Also note the police dont choose the omega without good reason. Safety is one of those good reasons and some are still in service or at least very recently retired. You have the same sport model mv6, which is lowered with better suspension than other models.
So, something is definately not right, as you suspect by the sound of it. Some things to ponder.
No amount of traction controle will save a complete loss of grip from diesel, ice, flat bald tires, punctures, or any sudden change in grip that over powers your tyres. Or as tunnie says, cornering beyond the tyres grip level. Remember tc can only cut the power applied. It can not save a slide on corner speed with a closed throttle say.
Mechanical faults should not be ruled out either. The Omega is a bit fussy on set up, camber, toe, trail all have a bad effect if out. Various bushes can fail or degrade, springs brake, shocks fail, etc etc, and turn the car into a complete barge to drive and a poor grip condition arrives very easily if things are missed, a valid MOT is no guarantee, not by a long way.
Tyres themselves however, well a certain amount of preferance is involved, but certainly price is a clue. Michelin primacy "can" come out at £600 a set but can last 30k which makes them quite cheap, if you can afford the outlay, will last, grip, give good stability and be quiet ish. In reality not many pay that much and some find fault with them. You can pay less than half that for 4, yes, and i guarantee they will be hopeless. (Q loads of members quoting "my 20 sobs a corner sling slimes or wally ditch finders are good tyres". Well as black and round goes they are tyres, yes, with groves and a speed rating, but shite, end of)
Michelin primacy
Dunlop sport max or sp 9000
Continental sports contact 2 or 3.
Can personally vouch for the above, Dunlops are imho the most stable and give a good planted feel but are a bit noisy. Primacy give a little less grip(we are still talking premium levels) but last longer IME
Conti sc 3 i have fitted now, very similar to older sc2. Quieter than the others, possibly more grip, but less accurate, by that i mean a tad of tramlining.
I also considered Bridgestone potenza said to be very grippy, by a member on here.
Pirelli p zero, iirc, where slated a while back, by some members on here, for the Omega. Appalling tramlining and better suited to front wheel drive cars where some of the comments.
Falkens, considered a premium tyre by some very knowledgable people,(WIM) 452s are ok for grip but less stable still, being softer dont last as long as the harder 912s that i had (here we go) which are absolutely appalling for stability, they pull and wonder all over the place, i seriously thought there was a fault with the car. However, both these models are exceptionally quiet, and well priced, i paid 370 ish fitted and balanced, for a premium tyre, but my 912s, the harder model, where on course for 15k life span, which makes both models quite expensive imho. Grip levels on both these models are not even close to either the sc2 or 3 or either Dunlop model mentioned above, but all will last longer. Hth :-)
What tyres did you have fitted when you spun? And where you on the power when it let go?
