Just replaced tires . I put NOKIAN WR 235/60/R18 with V speed rating. It is all "weather plus" rated also like sever conditions /winter. A road became silky way, no bumps, quite and more stable, also tryed today in a snow and I can not believe- ESP flushing almost GONE. NOKIAN also has a summer perfomance tires, but... my wife will kill me!!!.

 

Nokian? Sounds like a Star Trek cell phone.

 

Haven't heard of Nokian Tires, but I've had a lot of good miles on Toyo Proxies in the past. You're tires are 'v' rated so they should perform well in the summer for you.

 

Yes guys it is a company from Finland and they are making probably the best winter tires in a world (expensive also). They have a website www.nokiantires.com.
For winter also I will recommend winshield wipers made by VALEO , I bought from a Tirerack cool toy and works pretty well.

 

I put some Goodyear Triple Treads on my PT Crusier and they are a nice riding tire and have (so far) been very good in the snow! Don't know if they make them in 17" or 18" for the Magnum though.

 

As far as wipers... I like PIAA
Super Silicone Wiper Blades
