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.
And the differences grow by the size. 315/35 has never had TOO many options, but of the 2-3 sets on the rear (Goodyear, Vredestien, Firestone?) I've measured OVER 1" width difference between makers.

For the OP I went through sufficiently traumatic research replacing the Vredestein worn fronts (they don't ship the brand to US anymore - don't make many US sizes anymore either) and settled on the Conti DW. Shame if they quit the 275/40 now. As far as 'quiet' I just figure all tires get noisier as the rubber cures out (as in after couple years it always seems louder). I can't give thoughts on BFG, but it'll help overall if you tell us how many miles/yr. Unless a DD you might find you wanted to prioritize non-snow hy-performance after all.

Bill.. thanks for more detail. The 255 x 45 would probably be an acceptable tire. However I believe at this point I'm going to stick with the 275 x 40 for the 'look' and go with the Continental Extreme Sport. Its the only Continental tire offered that the tire shop can find, even though Continental shows a 'DW' on their website, no one seems to have them. The 'Sport' is apparently a new offering. I am estimating putting only 4-5k miles a year on the Camaro, so that should put me into a 5 -6 year aging on this 'Sport' and at that point the tread will likely be low and the tire will be ready for replacement. Thanks again!! -Gerry

I bought the BFG Comp 2 A/S in 275/40/17 from discount tire direct a few weeks ago. I can't comment too much on the road noise as I don't drive the Imp much, but in my limited time with the BFGs I like them. That being said I don't pay much attention to tire noise. They don't seem any noisier then the Kuhmos I replaced. They do seem to grip really well.

I used to run the Conti DW on my car also. Two years ago I was going on the Hot Rod Poour and needed a set for the long haul. I knew that I'd be burning them up on the highway, dragstrip and autocross courses so I went cheap. I got the Sumitomo HTR Z3 tires and will buy them again. They look great, autocross well, are quiet and almost hydroplane proof. I've put over 10,000 miles on them with no issues at all. Tread wear is down a bit but with the Power Tour craziness, I expected that. Dozens of burnouts and autocross sliding around does not allow for an accurate mileage review.

Woah! You reminded me of yet another one of the sets I've run. However, I did just the HTRZ version as I don't recall too many other suffix variations that many years ago. Relatively good choice at the time I recall. Cheap, rain pattern, and one of the few available in both 275/40 and 315/30.

The only slight negative was it seemed a little hard compound with symptoms being very little squeal around turns (just pushing), easy to light up the rears and with little no noise and no patch. There again I wore out the fronts after 8 years (20k?) and gave away the rears with 30% to a friend for burnouts. The only reason not repeating was good reviews on Vredestein. Maybe one of the several versions of Sumitmoto is worth a try Gerry.

The Z3's are great handling tires but don't even think of running them when it's winter cold outside. They are a maz performance Summer tire. I took them out this past winter on a cold, dr day. I wanted to see just what that warning label meant. Traction was about like a hockey puck sliding on a teflon frying pan. Literally much worse than I could have imagined.

I have run the G-Force Sports for quite some time in both 275/40-18's and 275/40-17's and have loved them. They wear nice and even and perform well in my opinion. The 18's were originally on my Olds Custom Cruiser and are now on Sarah's Buick hearse. Still lot's of tread but dried out and we have had them since 2009ish. So they will get replaced. The 17's are on My Cadillac hearse and may go on Sarah's car. I also had a set that were on a G-Body wagon and then went on a rwd turbo brick before selling the car with them. Great price for a great tire in my mind.

Thanks 96Black. The lack of a repeat with the Continental DW's is frustrating. Vendors have their reasons but consumers always pay the price. Tires is a place I have never really scrimped... same with brakes. I have selected the Continental Extreme Contact Sports simply because I feel they will be a quite tire. I'll certainly post back after getting some miles on them. I put 80 miles on my Camaro yesterday with the 16 year old BFG's on it. What a noisy beast. It was like driving with snow tires on all four wheels and having a bad whine in every axle. I'm praying the Continental Sports remedy all that.... unbelievable how hard the tires are. They have been inside, so no UV or heat cycle damage. They actually don't look too bad till you consider they are 16 years old. -Gerry

Thanks for the comments. I'm curious how quiet these are though. With the windows up and running at 60-70. For me on my Impala with the Kuhmo 255 x 50 x 17 ASR's, its very noticeable. The BFG G-Force Comp AS was going to be my 2nd choice for the Camaro but I'll not have that car on the road in much other than nice weather. -Gerry

I have the Kumo ECSTA SPT 255/50 17's. Not a noisy tire. W rated directional tire. 320 tread wear

Never seem to find the same tire brand a second time when I need tires
