Nexen... NOPE!
There's 'smart' budget tires. And there's 'cheap' budget tires. These are just cheap.
I won't recommend the top tier of summer tires to anyone who doesn't use them competitively - Most people simply don't need it.
However, there a number of competent summer tires out there that are well known, tested, and cheap.
The Tire Rack is a great place to do your own research into tires, but they don't carry everything.
Two tires I would recommend are the Kumho Ecsta SPT and the BFG G-Force Sport. The Kumho is likely a bit cheaper than the BFG, although both will be priced slightly above the Nexens you're looking at.
(Just to confirm... You have a set of 'winter' wheels/tires, right? Even if they're just all seasons? Because while you CAN run summer rubber year round in our climate, it's extremely stupid, IMHO, to do so. Summer tires lose a great deal of their grip when temperatures drop close to the freezing mark. If these are going to be your one and only set of tires, DO NOT get summer tires)
