My experience so far on my 2.2 159.
Bought the car at 9k, 1 year old at that time.
First (original) set of Good year F1 tyres, 225/50/R17 -
Front - 18 k miles on original tyres : Noticed excessive inner wear at around 12k. Took it to dealer who set the fronts to parallel and made some adjustments (don’t remember what)
Wear on inner reduced considerably but not completely. Changed at 18k with outer and middle at minimum tread, inner at almost zero tread. Replaced with Uniroyal Rainsport 2 @ £130 per tyre including fitting. Handling and grip improved substantially over Good year F1, no more tramlining, more stable under braking, plus looks sporty. Have done 12k miles since fitting, Half the original tread (these tyres have almost 8 to 9mm of tread when new!!) remaining on outside and middle, slightly more wear on inner but not excessive. Expect these tyres to last atleast another 6k to 8k miles.
Rear - 27k miles on original tyres: No uneven wear. Worn to minimum tread depth evenly. Replaced with Nexen N3000 @ £81 per tyre including fitting. Handling and grip improved considerably. Slightly improved fuel economy, less noisy than Good years. Done 3k miles and is still almost new. Expect good life out of these.
I don’t believe that all those big brand, overpriced, under performing tyres are really worth it. Am quite pleased with both my purchases and will use them again on any car without hesitation. For half the price they outperform the big ones both in terms of grip and value for money. I even drove through big puddles of flowing water last weekend during heavy rain and the car never lost grip or aquaplaned badly doing good speeds along A and B roads.
So in summary, I have not had major issues apart from slightly more wear on the front inners. Planning to get the wheels aligned again to maintain the performance. All this with reasonably spirited driving (especially after my JTS has been transformed into the 2.2M, now badged
