tire load

[Ascastlat]

hi guys. aside from the e90 i also own a Vw Scirocco R

tire specs are Bridgestone Potenza Re050a 235/35 r19 91Y

one of my tires was slashed by some guy in a parking lot and needs replacing.

unfortunately Bridgestone already phased out the 91Y load and only sells 87Y.

can i replace one of my tires, right rear, with the 87Y?

the car is only 1300miles old and i dont want to replace all 4 of them

i mainly use the car only for highway driving 60-80mph and city driving.

thanks and hoping for ur help
