DougsVic

I have a 1997 Ford Crown Victoria, model Police Interceptor.
I cannot locate original tires anymore: Goodyear P225/70R15, 100V, Eagle RS-A radial.
I may install (downgraded speed rating) different tires: Continental CONTITRAC P225/70R15, 100S.
(partial rating scale: S 112, T 118, H 130, V 149)
Has anyone done this already?
And how will this impact performance/handling while going 75 MPH on Interstate highways (type of driving)?
Please comment on severity of impact on handling and safety.
I am aware that other, very expensive, 100V tires are available.

Going by what speed you intimated is your normal use , dont see why you cant use the lower rated tyres . I changed tyres on one of our cars recently and uprated speed , but now regret it as they seem to give a harder ride probably due to less flexible / stiffer walls / tread pattern .Especially now with winter approaching might change back to original spec. which I think will give better grip in snow / ice due to more flexability .But that's just my opinion , others may disagree .
