OK to use Michelin A/S Plus FRONTS with Michelin PS2 REARS?
 

My stock IS250 currently has Michelin PS2 Rears (255/40ZR18) with 12k miles on the (60% tread left). It's time to change my fronts again. Would it be ok to use Michelin A/S Plus on the fronts (225/40ZR18 )?

I want to use the A/S Plus mainly because they should last a good 10k miles more than the PS2's, and they are also cheaper. Would it be strange if you use these up front with the PS2's in the rear (noise, handling, ride, etc)?

I am anxious to see this answer. I heard there are compatibility issues. This is bothersome as my staggered sizes force me to use the combination of tires and I may be forced away from the Michelins altogether.

Wouldn't be the end of the world, but keep in mind you are mixing different types of tires. The PS2 is a ultra high performance dry / wet tire, the Sport Plus is a ultra high performance all season tire.

In dry conditions, this might not be horrible, but if it gets wet or snowy out, then the vehicle will handle very unpredictably... more than anything, it will oversteer in adverse conditions, but understeer in dry conditions...

I wouldn't recommend it...
