Tire Question: Currently running Pirelli P-Zero Nero M+S in 245/35/19...(more)

[mnkyA4]

with them tires being wider they are poking out more then I'd like since I have to run 8mm spacers to clear my brakes. My question is this:

Is it ok to run on the 2 front tires the same brand of tire minus the M+S aspect in 235/35/19? (the tread patterns are the same i believe)

I know I will have rotating tires issues, but eventually I will be going with the "approved" tires size of 235/35/19 down the road.

We recommend against mixing for two reasons; first the all season rubber compound does not provide the same level of grip than the summer compound tires (not as strong in wet, primarily) so the car would have unpredictable handling when driven at high speed. Secondarily (and obviously) the summer tires would be useless below 40 degrees (F) so in a cold snap you'd be in trouble.
