Speed Rating ????

[CTt3P5]

My question is how much does a different speed rating really affect performance? I am pretty sure the P5 came factory with 'V-rated' tires, please let me know if I am wrong. Found some tires that are 'H-rated' and was wondering if that will affect driving dynamics at all. Thanks

Generally, the higher the speed rating, the stiffer the sidewall, which'll affect cornering performance.
