    Non low-rolling resistance tires and efficiency

    I switched to Non LRR Firestone Firehawks on the front at 9k miles and now at 12k, I have only noticed a 3-5% reduction in EV range but noticeable increase in traction. I still get the crappy stability control kick in when I get too much lean into corners.

    Mixing stock and non-stock tires

    After my stock front tires wore out at 9000 miles, I swapped them out a few months ago with non-LRR Firestone Firehawks with no noticeable range decrease or issues. I do notice better traction and less of the traction control kicking in on the mountain roads. Have 3000 miles on the tires now.

    How many miles on your Saprk EV

    Mixed size stock tires?

    The front tires were already worn out and nearly bald and traction control was kicking on around most freeway ramps.

    Mixed size stock tires?

    stock tires are horrible. Just trashed the front tires at 9800 miles and got non-LRR Firestone Firehawk instead. Much better tire so far and not much range loss.

    Stabilitrak seems over-sensitive? Any way to disable?

    I guess if you consider more traction equals quicker acceleration, then yes, but really just nice to not have wheel spin everywhere.

    Stabilitrak seems over-sensitive? Any way to disable?

    So I had 2 Firestone Firehawk GT tires (non-LRR) on the front and left the OEM tire on the back since they don't look worn much at all. It looked like the range isn't affected much around town but will find out later when we take longer drives. The grip with the new tires are MUCH better and...

    My two GM vehicles

    Steve, that looks like my driveway except we have a Charcoal Volt with little blue Sparky. Great combo!

    Best replacement tires?

    Problem is the OEM tires are such poor quality so getting another LRR type is preferred so at least there is a mileage warranty unlike the OEM ones.

    Best replacement tires?

    No snow and not much of a rainy season here in Silicon Valley CA so a all weather tire is preferred. Also never drive on dirt or gravel. Just need a good commute tire that doesn't reduce range much but a longer life than the crappy OEM tires. I do drive the car every few weeks on winding...

    Best replacement tires?

    Have about 9000 miles now and noticing the front tires are badly worn and th Stabilitrak kicks in on most corners and off ramps now. I am looking around for replacement tires and wondering if any of you have already done this and how your range, handling and tire noise changed and what brand you...

    Stabilitrak seems over-sensitive? Any way to disable?

    I did the round trip to work today on the winding Hwy 9 and Bear Creek Road home and the Stabilitrak was absolutely maddening!! It was hitting the brakes on most curves and sucked the fun out of the drive. Our Volt handles the road WAY better. Even when I turned it off, it kicked back on...

    Stabilitrak seems over-sensitive? Any way to disable?

    @emotodude - I too now commute in the Santa Cruz mountains in my Charcoal Gray Volt and pretty sure I saw you on Bear Creek a few days ago. Blue Spark EV correct? Anyway, I also drive my wife's Spark EV up the hill on occasion and really noticed the Stabilitrak messing with my driving. I did...

    Spark EV Low Gear Mode

    We love the feel of driving in L and use it 100% of the time in our Volt and Spark EV.

    Finally picked one up!

    @ crash - SparkEV stats is just a fun way to see other Spark EV owners daily use and overall mileage compared to your own and it keeps track of most EV miles driven in a day. Mike Rosack, he webmaster, is trying to get it to add more functionality to it, like Volt Stats has. Congrats on the new...
