Default '15 IS250 AWD - Two Different Brand Name Tires On Front/Rear? Help!

Hi All,

Recently purchased my '15 IS250 AWD in March 2018. It has a staggered set up, and when I purchased the vehicle it came with the following:

Front: Bridgestone Potenza RE760 Sport (Performance Summer)
Size: 225/40R18

Rear: (OEM) Bridgestone Turanza EL400-02 (Touring All Season)
Size: 255/35R18

My question to you guys, is it okay to have two different brand name tires on the front / rear? This would be my set up:

Front: Bridgestone Potenza RE760 Sport (Performance Summer)
Size: 225/40R18

Rear: Michelin Pilot Sport A/S 3+ (Ultra High Performance All-Season)
Size: 255/35R18

My front tires are still in good condition (8/32 thread) and eventually once they are worn down I would switch them over to the same Michelin Pilot Sport as the rear. They quoted me $920 to change all 4 tires to Michelin but my front still have good life in them. Again, I have an AWD staggered setup.

FYI, I also live in New England.

Any thoughts / opinions? Is it safe / would it damage the vehicle?
Thank you!

As long as the wheel setup is the same as stock (ie. 225/40/18s front, 255/35/18s rear) and the tread life on each tire are evenly worn, you'd be fine from a driveability standpoint with different brand tires for front and back. The only issue I can see is how the car grips if you were to drive in some harsh weather like torrential rain or snow with the different tread patterns. However, being an AWD setup I would imagine you'd be OK as the power would go to all the wheels.

But with regular driving at normal speeds whether highway or city, I wouldn't see a problem with different brands for front and rear.

It does seem a bit strange to have summer tires up front and all-season in the rear. I wouldn't be concerned about the brand as much as the performance class of the tire. Personally I wouldn't do it. If they were all summer tires, but of two different brands, perhaps. But I wouldn't mix summer and all-season.

I have all-seasons on front and summer tires in the rear. This is not a problem at all if the speed ratings are matched. The handling might change a little bit given the rear tires are sticky while the fronts are harder compound. So potentially a bit of understeer or oversteer depending on the what tire is in the front. But overall, for daily driving, its not a problem at all.

I'd be worried if there's snow on the ground. The summer tires are going to have a lot less grip in that situation. Since the OP has summers in the front, this is less of a concern, but if they were in the rear, oversteer would be a problem.

If the OP is planning to use these year-round, the summers would be pretty bad in the winter anyway.
