It all of them really. For example, I've got Lassa Impetus Sport tyres on the front of the E39 and they are the same as Bridgestone's Potenza RE720s I used four-five years ago. Made in the same factory. And Lassa is indeed owned by Bridgestone. They also perform brilliantly.
BUT, Bridgestone's current offerings will have moved on. So there is always a good reason to buy the top branded premium tyres if you can afford to do so.
Cost no object i would be doing just that. At the moment, cost is an object so have become a thorough researcher of midrange tyres. I won't entertain the real cheapies (Wanli, Linglong, Nankang etc) but many people report good results with these.
The ownership of a brand alone is not a reliable guide to quality and performance (all aspects thereof).
I have Nexen N2000 on the back at the moment, the fact that there's an association with Michelin is not enough to inspire me to buy them when these need replacement. But, then again, they work very well.
On the contrary, I fitted Goodyear NCT3s to my Nissan in 1999. Supplied by Just Tyres, Oxford Road, Aylesbury - I have no qualms naming the supplier and fitter.
They were horrible. Slid all around the place, wet or dry. Made in New Zealand. I contacted Goodyear UK and was told that those tyres are designed for use in Pacific rim countries where daytime shade temperatures are frequently in excess of 110 Farenheit. And that Goodyear UK has no part to play in the supply of those tyres to the UK.
Clearly not much good in the UK then. So I took them off and had 'em replaced with 'proper' European made NCT3s. These were supplied and fitted by One Stop in Thame, Oxon. (Thanks due to Nick at One Stop for his superb knowledge and advice).
Just Tyres denied responsibility, telling me that the tyres were E-marked and were therefore UK legal. They were thus marked, so any chance of a legal case being pursued and upheld was unlikely. I left it be on that basis.
JT should be thankful that no RTC occured otherwise I suspect I would have had a very strong case against them indeed.
I am not concerned if Just Tyres' read corporate marketing bods or legal bods read this thread. I am simply reporting facts. I cannot be found guilty of libel or slander simply by reporting facts.
