Now, I'm not the most automotively-inclined, but I know it's not a great idea to run winter tires in summer, due to poorer handling, lesser fuel economy, and greater wear on the tires. However, I've hardly driven since winter (I feel like a shut-in between way too much work and little social life, ha) and, now here in July, I still haven't gotten around to chaging my tires back to summer treads.

I have a set of new GlacierGrip II's on my Chevy Malibu (no studs). I don't anticipate a lot of driving between now and, oh, late September (when I'd put on winter tires normally -- first snow's usually mid October). Mostly around town a few times a week, but possibly a couple of 4-6 hour highway excursions. With hot summer temps (which can hit 90F+) am I ok to drive on these things -- especially, am I safe on the highway? And will I completely destroy them for winter?

Thanks in advance. The tires are speed rated S,T if that helps.  

Winter tires run hotter than Summer tires (or All Season tires for that matter), and that increases the risk of a heat related tire failure, which sometimes has tragic results.

Speed = heat.  So the short trips aren't a problem, but the 4 to 6 hour highway excursion is a recipe for disaster!  

yea, I also sometimes forget to change tires or I just leave them on if they are under 4 mm. That is not such a smart thing to do I agree. Fuel consumption is bigger, car Is too loud and Tyre failure can happen, car performance is limited.  

Yes,it is perfectly safe to run snow tires all year long.  For more info here is a link to my local Mastercraft dealer that carries the Galcier Grip tires - JCM Tires
