I was lazy on my drive home from work and ran over something which punctured my tires. It pretty much tore the tread.

Is it safe to drive to the tire shop in the morning to get a new tire?

 

That's is why they call them runflats...just keep the speed down, and drive sanely....
A runflat can be run, while flat for a limited amount of time....so you can get it fixed, or get to a safe location. If you were planning on reparing the tire, I would say drive as little as possible, and go slow..( to prevent heat buildup, which may render it un-repairable), but since you will be replacing it...no worries unless the belt/treads are comming off or there is a huge hole...

 

yeah. There's a pretty ugly gash on the treads which makes me worried about driving on them.

 

It got you home anyway....
If it is cut all the way across (all the way into the threads and belt, beyond the tread) or you heard/felt odd things...slapping sounds, etc, be careful...remember, I think the total miles they recomend on a flat runflat is 50 ish at 0 psi at non-highway speeds.

 

The Gen 1 Owner's Manual says you can drive 95 miles at 50mph max for a tire with 0 PSI.

 

We are a little more conservative and recommend no more than 50 miles at 50 mph max........

 

Here's a couple of pictures that shows the extent of the damage.




Sorry about the blurriness

So, it may be alright to drive?

 

It'll be OK to drive. I hit something that took out a quarter size chunk of the tread plus broke the inner plastic wheel well liner (never did see what I hit) and drove 40 miles to the nearest exit in the middle of Idaho with no problems. Actually drove the car around town while I was waiting the day for Tire Rack to drop ship a replacement run flat. No amount of tire slime will fix your wheel; this is a case for run flats, especially in the middle of nowhere.
