Hi Folks,
Since I read on the Spark discussion list that someone said the motor would turn off if you put a smaller doughnut spare on the front wheels (due to the traction control getting confused) I had to try it (since I didn't want a nasty surprise on a cold/snowy/rainy night). I put one in (found from the great god Google & Amazon) spare kit for my Spark & Leaf. Today I put the smaller doughnut spare on the left front and ran up to 55 mph (occasional traction control warning on dash but no effect) and then tried again on the left rear (since on the Spark they have a 195/55 wider tire & wider rim than the 185/55 on the front). I ran fine in both locations at 55 mph. I then tried the spare I bought for the Leaf and also *no* problems. I don't know why someone would blurt something out on the internet without testing. For those who say they don't need a spare tire - they're not driving their EV's enough +15K miles annually like me and you'll periodically get a flat and want to continue to work without shooting the day with a $500 tow truck etc. BTW, I found out that short wheel base cars like the Spark-EV, Smart-EV & iMiev all have wider rear tires to compensate for the inherent over-steer of a <12 foot long car (Leaf is 14' and all tires are same). Putting wider tires on the rear causes some under-steer thus compensating for the short wheelbase. At first I was going to change the rim/tires to all be the same for tire rotation - but after reviewing the reasoning/laws of physics of the designers - I decided not to. Just have to rotate the tires side to side only. Have a renewable energy day, Mark Mark E.
