Tires for stock 16" rims

Hello,
I just replaced a set of Bridgestone Potenza tires with Sumitomo HTR z's after blowing out a rear tire (one of the bridgestones). The car is driving/handling pretty bad now, and I've had it looked at for alignment/balance. The garage put another set of tires from another 930 on it, and found that it was driving fine that way. But with the new tires on, it handles terribly. Garage feels that it is the tires.

Has anyone else tried these tires? Looking at Tirerack, there appears to be very limited options - these, the Fuzion ZRi, and the Hankook Ventus R-S2. Has anyone tried either of the other two brands?

Thanks,
Eric

Hankook RS2 is a good choice. I ahd them and rand them on the street for over a year and 2 x at the track. Not bad on the track and good on the street.

Thanks - I'll give them a try. Every time I think I've got the car sorted out, something else pops up! But I think I'm close now...

Are you sure you didn't damage (bend) your rim when you had your blowout?

Maybe your tires are out dated or you got a defective one?

I've been running those same tires for a few years now and have no complaints.

Good points - I had a race shop put the tires on the wheels, balance, and check alignment. I didn't specifically ask them to look at the rear wheel though. A friend said he had a similar experience with a set of tires and that it took a couple thousand miles before they ran right. The car is going back into the shop again next week, so I'll ask them to double check the rim.

Thanks,
eric

Chances are the rim is bent.
Bridgestone are good tires. I use them on my 79 930, no problems.
Have them run the rim on the balance machine by itself and see if it has run out....in other words is bent.
Or check the tires for out of roundness as well.....could be a bad batch.

Taking it back in on the 18th - thanks for the ideas which I'll pass along. I've been driving the car everyday, seems to be staying about the same. It is definitely better now than when I had sumi's on the back, bridgestones on the front. Bridgestones aren't even listed at tirerack in my rear size any more.

Thanks again,
eric

Bent rims the whole way around... I think 2 were far enough off the balancing machine couldn't come up with compensation. So now the wheels are headed to another shop to get looked at. I don't off-road, but I do drive the DC beltway...

Thanks for the ideas/suggestions!

I'm trying to work out what to put on now too, I was thinking of just getting some 17 or 18 inch rims but I just love the look of the fuches. Anyone else have any ideas, how about Continentals?
