Hi all,

I found a nice set of tires for the 01 STS and was wondering if they would fit properly without any issues.

Here are the specs:

Hercules Avalanche X-Treme

Tire Size & Service Description - P235/55R17 99T
Meas. Rim Width (in) - 7.5
Max PSI - 44
Max Load (lbs) - 1709
Overall Diam. (in) - 27.22
Section Width (in) - 9.79
Tread Depth 32nds - 13.0

If your STS has the optional chrome 17" 7-spoke wheels that's the correct tire. Look at the sticker on the driver's door - the tire specs sticker - what size tire is there ?

The only problem is the speed rating - a T tire is limited to 118 mph max speed - your car is limited to either 130 or "above 149" mph depending on the tire service letter on the door sticker.

The max cold inflation pressure is for Bonneville Salt Flats runs only. Your car likes 32 psi all arond, cold. Wheel nuts torqued to 100 lb/ft in a star pattern.

Oops, I forgot to mention...yes they're the 7 spoke OEM chromes.

So the speed rating is only for limitation purposes I'm assuming so that's not a big deal for me....don't really drive +150km. As long as the tire fits well and doesn't rub, that's all I was concerned about.

Thanks for the response, much appreciated.
