Where the rubber meets the road?

Kumho Ecsta ASX. 245/40/18 rears, 225/40/18 fronts on 7.5" front 355 rims (with spacers, naturally)

Kumho SPT, stock sizes on the stock wheels:
205/55-16 front
225/50-16 rear

I'm considering the "standard" upgrade the next time I buy tires:
225/50-16 front
245/45-16 rear

Or perhaps upgrading the rears only, to help reduce oversteer at the limit without unduly increasing low-speed steering effort. The car seems to have enough traction at the front with the stock tires.

I went from my older Potenzas RE07's (great thread left, but old age) to my new Potenzas RE01R's .... 225/50R16's. I got a great deal on the new ones from TireRack before they all sold out. So far, like em a lot.

What tire pressures do you guys run?

I use the pressures listed on the tire placard on the door jamb. Seems to work pretty well.

 

+1, but using standard sizes f/r.

 

Ooops... Just noticed my typo. My rear tires are standard size, 225/50-16, not 255's.

 

I run the pressures as specified on the door jamb sticker. Don't remember what they are off hand.

Any pictures of 245/16 tires mounted? Especially from from behind the car.

 

You should use the pressure recommended by the OE for the tire. The 328 is 33psi cold in the front and eith 33psi or 36psi in the rear depending on the tire.

According to Tire Rack: "If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when encountering potholes or debris in the road, as well as experience irregular tread wear. "

Let's see pix of these...

205/55-16 front
225/50-16 rear

I think I'm running about 35 psi front and maybe 36 in the back.

 

I have the following on my 308:

Falken 452's - Very impressed with them so far and didn't think that they would be this good. So far over 4,000 miles and 2 track days and they still look new!
235/45/17 in Front
255/45/17 in Rear

I also have a set of Toyo Proxes RA1's for the track in the same size.

Bridgestone Potenza's RE 760 series
Front - 205/55 @ 32psi
Rear - 245/45 @ 36psi

That's what was on the car when I bought it, liked the handling so kept the same brand/sizes when it was time to replace them.

 

DDIESEN looks G R E A T !!!!!!!!!!!!
We need more pics!!!!!

 

A new (aug 08)Aset of the oem size Goodyear Eagle F1's at 33/36psi per the 328 owner's manual. Tires work very well though I haven't done any track or similar work with them. They were great at 140MPH+ out in NV/AZ...

 

Tires aren't really "one size fits all".

If you run in cold weather, most of the "extreme summer" tires aren't for you -- they go noticeably off below 40F(4C).

For me, I just swapped the older S03s for new RE-11s -- the US specific auto-X compound. They are a very soft compound, so they don't turn in as crisply as the S03s, but they don't go cold in urban traffic.

I did look at the A048s, as they'll likely go on sale (with the A050s now out). But I'd never keep them at working temperature on most of my drives.

Also, if there's a lot of construction in your area, the stickier tires will pick up hardware from the road. I had six punctures in three years, in the Xtal city area, before the condo boom collapsed.

I find that my tire choices are different in the DC metro area than they were in the Boston metro area.

When picking a tire, you have to look to your own specific needs. Highway or city driving, track or street, dry only or all weather, summer or all season.

You have to select a tire that meets your needs, rather than the most "popular" tire.

The wealth of tire comparisons on the web is both good news and bad news. You have a lot of information -- and a lot of conflicting opinions -- so you have to make your own choice.

But look on the bright side: Modern performance tires are only good for six years or so, (even less in towns that don't clean their streets), ... so you're not stuck with your choice "forever".


For pressures: "normal" pressure has changed a bit from the '80s (when the door stickers for GY NCTs were installed).
I generally start around 32 psi, and then look at the tires in the office parking garage. (There's so much dust on the floor, you get a good idea of the contact patch across the tire.) (A stickler would go for a temperature strip to measure tire temperature across the tread.)
Once I have the contact flat, then I tweak f/r pressures for handling balance.
