The MP3 runs 205/45R17s stock and would be closer to the stock size for speedo stuff...

But those should fit.

I'm going to say yes because those are 2/10ths of an inch bigger than what I'm currently running ... but I'm on far less offset than stock too (me=+40, you=+55) so I'd say you should be safe.

Just so you know those tires will be approximately 4/10ths of an inch bigger than your stock tires. With that small of a difference I think you'll be fine. Don't take my word as gospel though - let a few more chime in with their opinion first.

GIVE THEM TO ME!! I'll worry about rims later.....

When your speedo says 60 you'll actually be going 62. Not too bad. They'll fit, but I would be afraid they'll look a little baloon like. Just me though.

Here's a good thread for anyone checking tire sizes:

The 205/50r17 is closer to the MSP 215/45r17 size so it should even be a closer fit. It's only off by a 6 milimeters or barely a fifth of an inch.

Ok, using the tire calculator, a 215/45/17 is 4% to slow the stock Protege tire size of 195/50/16.

A 215/50 is 7.5% to slow.

Seeing as the speedo is calabrated for the sotck tire size, a 215 wide tire should be run in a 40 series. It is a better match and only .4% to slow.

I realize that all of this probably doesn't really matter. But this is getting rather redundant here.

Yes, they will fit. Should you run them, I wouldn't. There is a lot of error with those tires. If you can get them cheap, then get them and run them if you want. (smash)

MP3 ECU vs. MP5 ECU

I really don not know the difference between a MP3 ECU and a MP5 ECU. Is there an avantage to switching them? If so, how much $$$$ would I need to spend.
