I have searched the forum for posts on my specific question, but cant find any, sorry if this has been asked before, but here it goes.
I recently bought a 2006 MX5 NC, but to my utter surprise and terror it arrived with 215/40R17 size Tires on the rear and 205/45R17 Runflats on the front, and firstly I just want to discourage, no, WARN anyone even remotely considering putting runflats on an MX5 to JUST DONT DO IT, AT ALL, EVER!!!
It tramlines to the point that it is dangerous to any living creature in its immediate surroundings, even at slow speeds (+- 40km/h).
But getting back to my question, needless to say, I am going to replace all 4 tires this coming week, and was considering maybe going for 215/45R17's all round, for the simple fact that they are slightly cheaper than the standard 205/45R17 normally fitted to the MX5.
Now finally for my question, has anyone got any experience with the above mentioned size I am considering, are there any downsides to going with 215/45 instead of sticking with the 205/45's, and then I would also want to know, specifically about the fuel consuption and performance, is there a noticable difference in performance, especially acceleration, as in my previous vehicle, when deciding to go to slightly bigger tires, there was a huge difference in acceleration, maybe partly because its 0-100 figures should be measured on a calender instead of a stopwatch anyway, but that is another topic alltogether.
Any swift replies would be much appreciated, because I drive about 100km's a day and am very affraid of putting myself into a ditch because of the runflats.
