I have a Chevy Trailblazer with 4/wheel drive. I do I need studded winter tires?

If studded tires are legal in your jurisdiction , and you see lots of snow and ice , by all means get them - they offer the ultimate traction in winter driving. I have studded winter tires on my toyota echo , and have less issues than many people with 4X4s . I have them mounted on separate rims , so that I can install them in a few minutes on my own driveway.The only downside is , studded tires are noisy .

No, you shouldn't unless your in some remote are where the weather is pretty treacherous. Normal winter driving on a 4 WD with good tires should be sufficient. The other downside to studs, they have to be off at a certain time of the year in some areas, or you can be fined. At least in Pa. that is true.

Weather determines if you need studded tires, not the vehicle.

A 4WD trailblazer in Miami is a waste of expensive rubber.

Depends on were you live and what the law is in your area.Ask some one that has lived in your area for a long time and has done allot of winter driving.

No maybe all terrain tires I got BFGoodrich rugged terrain pretty good in the snow they fit 17in so that would be good

Nah. Really depends on how severe the winter is where you live.

Read this and decide for yourself.
