What's the best tire size with no modification?

[cardsharp15]

Hi Guys!

I have just bought a standard 2002 ES (not GT) Model. It has its original 195/15/55 tires on it. I want to get a set of alloy wheels but with no other modifications on the car. I was thinking of 205/40/17. Do you think I will face any problem with this size?

I appreciate your help.

PS: Anyone knows if Enkei RS6 fits my car or not? Because when I check 1010tire, it doesn't find it for my car? (bolt pattern: 4x100)

you can go as big as a 215/45-17 without modifications - thats stock size on the mazdaspeed protege. if you only want a 205 width, go with a 205/45-17.

as for those rims, the offsets all look a little too low for the protege. you'll want something around 45-48 for best fit.
