Question
I have an '03 Mazda Protege5 with 195/50-16 tires.  Is it possible to go with a wider size on the same rim, and if so, what would that size be

Answer
Gavin,

From the rim perspective you have enough width to go wider by a considerable margin, but what I don't know is if there is enough room in the fender well area.  Unfortunately, no one I know catalogs this area of the vehicle.  So your best bet is to find an onlone club or a web site devoted to your vehicle and see if someone else has already done this and what problem he may have run into.

It has been my experience that going up one size is rarely a problem.  Besides I don't think going up more than 2 sizes is advisable anyway.

Hope this helps.
