[ausev] thoughts on tires

[chris clark]

Now that Mark Witt's old Ranger EV is finally finished, I have to replace the tires.  Unfortunately, I've spent all my money buying and working on this thing and now, money for tires is pretty limited.  If I could afford it, I'd just go by a new set of 225/70/15's like the ones it came with.  That's pushing $500, though, to get a set of good quality tires.  So here's my question.  I have a new set of 235/70/15's that would cost me very little to have mounted and balanced, but the tires are roughly 1/2" taller and almost 1/2" wider, creating a little larger 'footprint' and distorting the mileage/range computations slightly.  I've been told by Discount tire that with the larger 235's, a speedometer reading of 65mph would actually be 66 mph.  So the calculations would be effected about 1/65 and there would be a small increase in friction because of the larger footprint, at least this makes sense to me instinctively.  And this begs the question "would one size smaller tire decrease friction by having a smaller footprint?"  If the answer is yes, there are many 215/70/15's or even 215/75/15's available at salvage yards.  For some reason, though, 235/70/15's are very difficult to find used.  Enough of my ramblings.  Any thoughts?

  Hi,

  My name is Gary Ellis and I just subscribed to the AustinEV mailing list as I'm starting an EV conversion company, here in Austin, and wanted to introduce myself.  Our company is called ReinCarNation -- please check-out our web-site, when you have a chance.

  I'm very interested in meeting many of you at your next meeting, seeing your EVs and showing you my electric Miata.  I have heard about Revolt Custom Electric, but have yet to contact them to see what their experience has been like.

  Thanks and any feedback is welcome.
