Good quiet 275 x 40 x 17 tires?

Gents, looking for an opinion on 275 x 40 x 17's. In the past I have used Bridgestone RE7xx series and switched to Continental Extreme Contact DW's when Bridgestone stopped making theirs. Now Continental appears to have done in their DW line, only available in Extreme Sport. I am actually looking at a BFG g-Force COMP-2 A/S but am leary after a lot of BFG bashing here years ago.

What opinions and feedback can anyone give me on quiet BFG's. The Continental Extreme Sport is a very soft performance tire, I'm sure it might be quiet but I'm also looking for some decent wear. No snow driving, just wet/dry and quiet.

Thanks in advance!!

A little supplemental info.

My dilemma is due to manufacturer's tire selections going down the tube. Just like with our Impalas the 255 x 50 x 17 are no longer available in a wide range of options/quality/ride. My 2002 Camaro SS needs 275 x 40 x 17 and boy... same thing. Seems there are only a handful of quality options left, and despite me having found a great pair of Continental Extreme Contact DW's for my Firebird in the same size 3 years ago... Continental no longer makes the DW in that size. Their website says they do... but my tire shop cannot find them anywhere.

So I built the table below on paper for all that dimension info, rim width, tread width, diameter, revs per mile. Here is what I found. Interesting that it opens up a lot of options but only IF you are willing to trade a little width or height for the actual tire qualities you want. That said... here is my table and I hope you get something from it. All the info is from Tire Rack and the various sizes and using Continental tires as the source for numbers. I stuck the Impala OE 255 x 50 in there just so the post might be of more value.

Tire Profile Dimension Comparison ( na by 255 x 40 was no available data on Tire Rack )



Me? For my Camaro SS I'm likely going to sacrifice 0.9 inches of tread width at 275/40 and drop down to 255/45. But at 255/45 I gain 0.3 inches diameter and 9 revolutions per mile. I am after a quiet tire more than performance, and getting a little more 'economy' out of it as well. Ha. I'll have to tweak the PCM in the Camaro to get the speedometer accurate, but that's no big deal.

As they say... Your Mileage May Vary.

You'll probably shave a few pounds per tire which will help economy too.

Discount Tire Direct

If you can get past your TR loyalty, take a look at the choices offered via Discount Tire Direct.

Not "perfect", but there are still more than a few 275/40's available.

Discount Tire/DTD also has an excellent credit card, 6 mo>longer 0% financing, and frequent rebates.

Not to mention DTD has free shipping and no tax in many states....

I bought the cheapest 275/40/17's that Tire Rack sells... and I never once even considered "noise" in my decision making process.

Thanks Bill. Appreciate the feedback for sure shipmate. For me it is not about the price per se, it is about what quality I get. Noise at highway speed sucks. You know my story on the Kuhmo's I put on my Impala 2 years ago. They were noisy compared to the Bridgestones I had on there. Did not know about Discount Tire.

I started the thread soliciting comments about the BFG G-Force Comp 2 AS tires. Then I hijacked my own thread. Darn. I believe the 255 x 45's will have a subtle 'off' look to them compared to a 275. Clearly.

Thanks again Bill!

Thanks KW. I am leaning toward the BFG's, they are well reputed on Tire Rack. I'm thankful to Bill for pointing out Discount Tire. Clearly the selections these vendors offer align with their own volume and purchase agreements. Lately its become more difficult to determine if a particular model of tire is not on competing websites because of that or because of a production change.

FWIW, for all the years I ran the Camaro SS wheels on my Impala (now sold), the stock size tire (255/50-17) was the only tire I used--the wheels were an extra 1/2" wide, and they worked fine. I don't know if a 255/45 will suit you, if you're going for a certain look, but I'll guarantee the 275/40 will be "firmer" as far as your butt-o-meter.

The really interesting observation here is how the different tire manufacturers interpret the "math" when it comes to how tire sizing numbers translates to the actual product, when you can take the same size tire from 6 different sources and they all vary in dimensions, and often seem to ignore the calculated numbers. Some run narrow, some run wide, and actual tread on the ground can vary as much as 1/2" or more for the same specs.

You do have choices.
