As I was pushing the car a bit going down my windy road last night, the ASC kicked in prematurely




Sadly, those excellent Bridgestone Potenza ultra-low-rolling resistance tires used on the Gen1 Honda Insight do not fit the stock i-MiEV wheel rims.rmay635703 wrote:165/65r14 re92’s roll the best
Hey, we had some rain and the front Blizzaks and rear Enasaves have done a nice job of maintaining traction.JoeS wrote:Update on the new front Blizzaks and rear Enasaves:

This is a noticeably more sensitive response than normal, as 'normally' this occurs when one is really throwing the car into the curve. Guess this will make my tires last longer
(or I can disable ASC more often
).

These cars are super sensitive to tyre size mismatches between front and rear.
When I got my new Vredestein Quatrac 5's (previous post) I actually bought the rear two first - earlier than I originally had been planning due to a non-repairable puncture in the rear left, and ran with these two new full diameter tyres at the rear and the worn original tyres at the front for a couple of months until I replaced the fronts with new tyres as well.
During this time I noticed many anomalies with the traction control system. The main symptom was that rapid acceleration on a moderate left corner would sometimes cause the traction control light to flicker on and power to be reduced when there was absolutely, definitely not any loss of traction or wheel slip occurring - it was happening even on a warm dry road with relatively moderate acceleration that would not have been causing a loss of traction.
The other symptom I noticed is that sometimes when leaving work, during the first downhill leg regenerative braking would be severely restricted for quite a period of time, then after a while it would start working. As the battery was at 60% there is no reason why regeneration should be restricted. As the traction control will cut regeneration if it detects wheel slip on ice (which I discovered in winter...) I knew that it was probably the traction control causing this due to believing that regeneration was causing wheel slip.
I continued to see both symptoms intermittently right up until the time when I replaced the front tyres as well - as soon as the proportions between front and rear tyres were matched again both symptoms went away and never returned!
So I would not recommend mixing and matching different brands of tyres between front and rear on these cars, as different brand tyres of the same nominal dimensions often have quite a big difference in rolling radius that will upset the traction control. Likewise mixing brand new tyres at one end and heavily worn tyres at the other end (reduced rolling radius) can also cause a problem, as it did with me.

I had a local shop put them on for $80 two weeks ago. They look like great tires for the winter here.
They have been driving quiet. Some mileage has dropped but it's in the noise since temperatures have dropped and the tires have a slight larger circumference as discussed earlier. I would guess a 5% drop in mileage. But that's way cheaper than buying Dunlops.
