So... I have 13,000 miles on my baby and have already went through two sets of rears. The fronts are still fine. The fronts and rears are currently the RE040's. The rears are shot. Knowing that the RE040's are great summer tires but have a 140 wear rating and not being able to rotate these tires, getting about 6,500 out of the rear is not bad. My driving habit is a little spririted, but that is it. Anyway, instead of making a major investment and switching out all fours, what I would like to do is keep the fronts, and replace the backs with RE960AS Pole Position tires. Thinking... I don't race the car, I am staying in the Potenza family, will get a little harder tire thus more mileage while not giving up ratings and load, and will get better traction out of the rear in the rain.

Is it OK to mix the RE040's and the RE960 AS's?

Any feedback whether good or bad is welcome. When the rears go on this set, I will be replacing all four.

Thanks!

 

Not sure what you are asking. You want a performance tire with good tread life? Look at Dunlop SP Sport Maxx.

 

I have the 960as and would highly recommend them.

 

What I am asking if there would be any problem with mixing the RE040's and the RE960 AS's? (Keeping the REO40 on the front and putting new RE960 AS on the back.)

 

People have diff pair in front and back all the time. I would think as long as they're both in the same category (ie both high performance) you should be ok and the sizing is right

 

you want the same tread levels and same tread design on the same axle.

it's ok to mix.

 

Great tire but not the best idea to mix them. With the large difference in tread design and compounds (being a/s and a summer) handling would be pretty poor. Check our article on mixing tires here Mixing Tires

 

^that never even crossed my mind as I cannot imagine a z owner using all season tires. good looking out, neal.

 

I can't imagine what you are doing that is having you go through your rear rubber that fast. How were the tires wearing out?

 

I never had a problem with my 960AS, I was actually able to get some 2.0 60' times with them as well.

 

I agree with Neal.

If you mix all season tires with summer performance tires, you potentially introduce some very disadvantageous handling characteristics. This problem is even worse for people who are in climates where temperatures vary significantly (i.e., approach freezing).

The OP (350zWVU) is in Pennsylvania where temperatures go from warm to possibly quite cold, and that is a significant consideration when running “mixed tire-setups.”

Thanks to all for the input. Concerning what I am doing, I don't know. Look at my mileage, this car is a garage queen for the most part. I jump on it a bit, but not like I stole the car. Concerning the temperatures here in PA, I don't drive the car in the winter unless the temps are above 40 degrees and the roads are bone dry with no precipitation in the forecast. Concerning speeds, I dont' race the car, may once in a while get her up to 105mph and back down quickly.
