Apart from rolling radius, what are the pros and cons of going for the two profiles?

Is there a better optoin for absolute performance or is teh extra compliance from the 50 a good thing in a stiff chassis such as the 7 chassis

65 is better.

top speed and Acceleration are a factor to look at.

with 45 profile on my car rather than standard 40, i can do an extra 5 mph top end but getting to 61 mph is longer.

plus my speedo is wrong with bigger tyres.

Look at the difference in price 195/50/15 are common size so tyres are cheap.

Yea, I was more looking at cornering performance.

Rolling radius is something that will be looked at too but primarily I was more thinking about the on road performance and how it affects handling/stiffness etc
