While it is not recommended, I don't think it will make that big of a difference for regular daily driving.

I've done it before on numerous occasions, and to be honest, I never really noticed any significant difference for city driving. I've gone through setups with full Pirellis front/rear, Michelins front/rear, Conti's F/R, Nittos F/R, and mixed setups with pirelli front, michelin rear, nitto front, michelin rear, etc... no biggie.

Would it have a big difference on the track, or in the rain? It definitely could, but again, if it's for regular driving, I think you'll be alright.

Currently, I'm gonna try out a full set of HTR-Z III's... If price is an issue and the reason for mixing tires, you might want to check these tires out for a great bang for your buck performance tire...
