Help.....Tire Sizes

[j.]

I have a 2006 Saturn Ion that has P195 60 R15 size tires. Would it be OK to replace with P195 70 R15.....or maybe P195 65 R15 size tires. Would it make much difference in the way the drives on curvy paved roads?

first thing on deciding size - how does it effect your speedometer check here you need java installed to use it http://www.miata.net/garage/tirecalc.html
