I agree Nexens are very good tyres, by no means are they a budget quality brand.
They are an independant though, not owned by a bigger company for instance michelin. Michelin has Bf Goodrich and Kleber in its stable but not Nexen
Do you really need to buy high priced race quality tyres for a family runabout that is only used to collect the shopping and the school run?
The Big boys now make the budget ranges! They realised that the only way to compete at the "lower end" of the market is to make budget ranges; they are usually made in the same factory as the High priced tyres! They use different names simply because if they put "premium brand" names on them then no-one will pay the high prices for the others!
Every premium company makes-or has made for them-budget ranges, have a look at this list of brands.
