Here is my question.

I have two basically new Pirelli P7000 215/45/17s that have been discontinued and cannot be found anywhere? The other two are bald.

I'm getting 2 new Continental ExtremeContact (215/45/17) on Saturday.

Is it bad to have different treads on diffrent axles?
How should I place them on the car? (Used Pirelli's in the back, New Continentals in the front?)


The Pirelli's always had bubble problems, so I'm tempted just to replace all 4, but at this point I'm real low on cash, and I would rather not waste 2 basically new tires.

sounds like the Pirellis are kinda older. It might make a differance in the gas milage. It could slightly dangerous to mix the tires like that. Better safe than sorry.

 

Best to replace all 4, but if money is tight and two are still decent put the two decent ones in the front, new in the rear (at least that is what Michelin recommends and was proven to be much more stable and safe - older tires up front, new in the rear, fwd and rwd - in an article a couple months back when Motor Trend visited Michelin's proving grounds). Seems counterintuitive, but MT said it proved better when tested.

 

The pirelli's aren't very used at all, probably 85% tread.

They haven't been used for two years. I moved in NYC a couple of years ago and of course left the others at my sister's in jersey. Now I'm getting my car back as I moved right outside of the city.


I guess I'll mix match the tires and see how it feels. Thanks for the advice on placement.

Anyone else have opinions on the matter?

 

it's not a problem so long as they are the same size and type of tire. ie. you don't want a high performance summer tire up front with some all season type tire in the back.

 

I would put the two new tires in the back, then the old ones in the front (in hopes that you're replacing the old tires really soon). I wouldn't put two different tires on the same axle, even if they're the same size because manufacturers sometimes have different specs and this results in different size tires. I have two sets of 15's with different brand tires, but the same size. The height of one tire differs from the other, so I'm guessing that it might be the same for you as well.

 

im doing it now and its no big deal

 

thanks for your help.

I can't wait have my rims back on my car. I've had plastic hubcaps and 15s on it for the past 2 years. (I also probably put less than 4000 miles on it during that time as well)

 

damn i wish i could do 4000 miles in 2 years i did around 30 this past year

as for the tires as long as the same comp are on the same axle then there are no worries at all. put the new on the back that what if you do a couple burnouts w/ the old then you would get the new ones to match tht rear

 

i mixed and matched my tires for abt a yr.... no prob...
