Spend your money on better quality tyres in the manufacturer specified sizes.
Basically the wider the tyre, the larger the contact patch (rubber on the road) meaning more grip. But, generally only when matched to wider wheels.
Wider tyre on the stock rim may get you better traction for acceleration, but will hurt cornering grip due to increased sidewall flex as the wheel rolls around in the tyre more. Current trend is to undertyre a wheel anyway as it gives more predictive handling on the limit. look at an M3 or AMG - the wheel is wider than the tyre causing a stretched appearance.
My ten cents, start reading tyre reviews and stick to the sizes that the Mazda engineers chose for a reason.
You need weight to press down on the tyre if you have a lighter car wider tyres only make you slower it adds weight. If you have a 3mps 235/245 is the max you want to go as the rest is a waste. MPS6 you can go a bit wider on the rear 255. Wider tyres than 235 wont help you corner faster.. laws of pshyics= when you corner the weight is on the outside of the tyre hence no traction on the inside, so you are only adding weight to your wheels if you go wider.. Dont forget Mazda has set the car up for 215/225 tyres all suspension componants are suited to this size. Supercars are set up for 305+ wide tyres etc... Unless you have tens of thousands to spend and alter all suspension/testing parts of your car including lead weights for ballast to get it right... listen... If your after looks only than go for it, but wont make you faster
