Pole Position RE970AS on stock wheels?
 
I currently have 205/55/16 Pirelli Neros on stock 6.5in wide rims. The tires always seemed a little dodgy in the wet weather, and I'm seriously considering going with the new Bridgestone Potenza RE970AS (All Season).

Questions (about the RE970AS's):
*Does anyone have experience with these tires (especially on a WRX wagon)?
*I'm seeing mixed reports on road noise. Any opinions?
*How does the actual tread width compare to other similarly sized tires (i.e. is this a wide or narrow looking tire)?
*According to the FAQ, it is possible to put 225/50/16s on the stock 6.5inch rims:[INDENT]I gather that there is no fender rubbing issues with the stock-offset rim?
Will going to a wider tire somewhat compromise the wet weather performance (i.e. hydroplaning)?
Will going to a wider tire really improve performance all that much?[/INDENT]
Note: my car has no suspension upgrades and I'm not auto crossing.

Thanks,
Jammon

Thanks, Paul:

You mentioned that you were running these tires a long time ago. I think maybe you're referring to the Neros? My question was regarding the Bridgestone RE970AS's, which I believe only came out a few months ago.

Clarifying my tread width question: Two manufacturers might claim to have the same tread width on their tires, but one will look narrow and the other will look wide, depending on how the manufacturers measure the tread. I was wondering if the RE970AS's appear to be a wide or narrow treaded tire.

Thanks,
Jammon

It was the 960's, I misread.

I see what you meant now.

BUMP...

When they measure tread. They measure depth, not width.
Patterns are not measured to that extent, as far as I know anyhow. At least not for most public spec listings.

Am I reading you correctly? Your looking for tread width info? Is this correct?

^He's talking about tire section width.

I would go 215 on the tire. I know the 09's came with 225's but they also came with a 7" wheel, the 11+ come with 235 but they're on an 8" wheel.

If you went 225 on a 6.5" there will definitely be some bulge, and if you don't to any aggressive driving, 215's are plenty of rubber. If you do ever want to go to 225's I would recommend at least a 7" wheel to minimize bulging and keep the sidewalls more vertical and stiff.

BLAZE2099 07-19-2012 10:26 PM

^ gotcha;)

I agree with a max of 215 for that wheel as well. A 225 will be a crazy overkill and like Chris said, there will be insane bulging.
If you want to look into some new wheels, than your options just increased a ton.

225/50R16 is rated for 6.0 to 8.0 inch wheel width. Quit scaring the guy, they're totally fine for stock wheels. 7" is ideal but 6.5" is certainly wide enough for those tires. Remember guys, 50 sidewall tires are designed for comparatively narrow wheels. I would go 215/50R16 as well because of the gearing advantage paired with the EJ205's 5-speed but 225/50R16 would offer more lateral grip. Especially when the tires he's talking about aren't even SOLD in 215/50R16! Bulged? No, that's bullshit.

RcrsWetDream 07-20-2012 06:32 AM

^ Who mentioned a 215/50/16? :confused:

Honestly, we're talking about a stock suspension WRX only driven on the street. He doesn't need more lateral grip. I would just buy the tire you want in a size that's cheaper. If it's a 225 buy those, if it's a 215 then get those ones.

Bulge is also relative... Bulge for a Jeep is a tire that bulges an inch past the edge of the wheel, and it has a purpose. Bulge on a WRX is much different. I like when a car has a wheel/tire combo that looks "meaty", but there is a line when the bulge is just obviously somebody trying to stuff as big of a tire as they can on the wheels they have (remember, to most bigger is better). At least it's not a hellaflush stretch though.

I would like to go with 215s, as well, but unfortunately, the 970s don't come in a 215 for a 16in rim. So, it's either the 205s or 225s. My concern with the 225s is the bulge and also compromising wet grip (i.e. hydroplaning). On the other hand, I also like a tire that has a "meaty" look. That's why I was asking about tread width. Years ago, I had a 300ZX and switched from the stock Eagle GTs to another tire. I remember being disappointed that the new tires didn't fill the wheel well as much, even though they were the same same size as the GTs. Anyone know how "meaty" the 970s look in comparison to other tires of the same size?

Thanks,
Jim

I see what you are saying. Go to a local tire shop and manually measure tires and log the specs.

225/50R16 is designed for your wheels. It can be mounted completely normally on an 16x6" wheel. It's not going to buldge and hydroplanning on a 225-wide tire with 3200lbs? That shouldn't be a major concern till you get substantially wider. The 225/50R16 is a better choice in every way, cept maybe price, than 205/55R16. Why doesn't your car come with wider tires? Subaru was cheap. They released the STi with 225 wide just two years later.

Garage One in San Jose, my Suburu mechanic, is recommending I go no bigger than 215, but as I said before, that's not an option for the 970s.

The Michelin Pilot A/S plus does come in a 215/55/16, but the tire diameter is 25.3" vs the ideal 25".

You're right that Bridgestone gives a range of 6-8" for the rim. However, 7" is the "measured rim width" (the size rim that all the spec'ed dimensions pertain to). This makes sense, since it's the middle of the allowable range.

I wonder how much longer I can continue to drive myself nuts with this decision?

Never go to Garage One again, they're idiots. Bridgestone TELLS you what wheel widths are acceptable and which ones aren't. You aren't even talking about a tire at the damn maximum. 45 sidewall tires and 50 sidewall tires are NOT the same with this stuff. People need to understand what classifies as a low profile tire before spewing this shit.

I was also thinking of these pole positions for my 06 wrx tr, I am still running the stock wheels so I though I would go with the 225/45R17 but the Z1 Star Spec are also intriguing. However after reading some posts here, it seems like I should stick with the 215/45R17 based on what you guys have been saying. I wish I could upgrade my wheels soon, but don't have the cash for what I want.
