I'm concidering volvo 17 inch wheels . I know there are quite a few of them. Thor, comet, scotia, Zeus, pegasus, spultor, etc. anyone know the weight of these? also other specs offset

Re: wheel weigh for volvo 17 wheels? (V50_T5)
Hey, looks I can finally help V50_T5 after all the help you have given me. I have gone through this exact thought process, recently. I'm still considering the 17x7.5 R5 from Evolve. It looks good, is light (18 pounds), is probably very strong, and will not have any rubbing issues (42 mm offset).
But I'm more recently inclined to Volvo wheels also, all coming from S60. They are 49 mm offset, 17x7.5 wheels, and will fit except they need hubcentric rings. The Pegasus is 46 mm offset, 17x8. MOST LIKELY I WILL GO WITH PEGASUS.

for info on weights of such wheels. Generally, the 17x7.5 are 22 pounds and 49 mm offset. The Sculptor 17x7 is 52.5 mm offset, also 22 pounds. The Pegasus is 25 pounds, 46 mm offset. Thanks for UKMatt for the info.
Not to bias you, but just to inform everyone of another guy's opinion, I've thought a lot about which wheel. In the end, they are all good options, all with different advantages, including the Evolve R5, which arguably looks the best. I'm probably gonna try the Pegasus wheel.
Here are some advatanges, disadvantages of the Volvo wheels
Sculptor:
pro: stock wheel, looks good, 52.5 mm perfect fit. For this, one might use 205/50/17 high quality sport tires and use the normal V50 wheel.
con: Using 225/45/17 on 7 inch wide is vastly inferior to 225/45/17 on 7.5 or 8 inch. Using 205/50/17 sport tire may give the biggest bang for the buck, but arguably not quite as good as 225/45/17 on wider wheel.
17x7.5 49 mm offset S60 wheels:
pro: close to 52.5 mm offset. Good weight - match Sculptor - fancy designs and many choices if you like any of them. Is the industry standard measurement rim for 225/45/17.
con: not 8 inches wide, none look as good as Pegasus (my personal opinion), need hubcentric ring, seemingly more expensive by a lot than Pegasus
17x8 46 mm Pegasus:
pro: 17x8 is even better than 17x7.5 for 225/45/17 for sidewall straightness and stiffness, arguably super-strong (designed for R), looks sporty and classy and not flashy (my personal taste)
con: 46 mm offset is a bit more of am offset / scrub radius change - effect still not quantifyable. 3 pounds heavier than 17x7.5 wheels, need hubcentric ring
By the way, 8 inches wide makes the 225 tire a few mm wider than 7.5 inches wide. But 46 mm makes up for the extra section width. So the 46 mm Pegasus with 225/45/17 will be about the same tire width as 225/45/17 with 17x7.5 S60 wheel. Both will grow less than 5 mm towards the inner car, from my own calculation.
Another aside concerning section width: http://www.tirerack.com is great. You might think that 225 is 20 mm more than 205. Not so! A sport tire has narrower section width because it has straighter, stiffer sidewalls. So going from 205/50/17 all-season grand touring to 225/45/17 max summer performance only adds 10 mm or so, believe it or not, looking at the maximum section width.
Hope this helps!

Re: wheel weigh for volvo 17 wheels? (bassman)
Thanks Bassman,
as you know I went with 18s but feel a 17s may be better. I am looking into a wheel thats a little wider than the stock s40/v50 so wheels like the thor, comet, the pegasus might be better. My most likely route is either pegs because of the 8 " width and the fact that it's a Volvo wheel or the r5 because they are light. either way I'm concidering a 235 45 17 as opposed to a 225 45 17. thanks a lot , that helped.

Re: wheel weigh for volvo 17 wheels? (V50_T5)
Sure, no problem. If it matters to you, 225/45/17 is more similar to 205/50/17 in terms of overall diameter than 235/45/17.
225 matches the stock diameter better.
Also, I think the S60 usually comes with 235/45/17 on both 17x7.5 and 17x8 wheels, so 235 should be feasible, forgetting about diameter.

Re: wheel weigh for volvo 17 wheels? (bassman)
bassman you have confused me, offset is not fixed, if you go up in rim width 1/2 inch you have to -6.25 mm from the offset to keep your rim centered. I've posted a link to an offset calculator. Yes there will be an effect on scrub, but it is far more important to center the tire in the well.
http://www.hrsprings.com/site/....html
Positive and negative scrub radii have benefits in different types of suspension. A MacPherson strut assembly typically performs well with a lot of SAI and caster, a system negative scrub works well in. Because both SAI and caster increase the amount of camber on the outside wheel when steering, the fulcrum pivot point is
also it is late, but if my brain is half awake, if you lower the car the lower arm goes up and IN and this messes the king pin angle which hoses the scrub, then you are up getting camber plates to bring the angles all back again.

Re: wheel weigh for volvo 17 wheels? (Oldman)
Lowering: yeah, I'm avoiding that whole thing for now. People have success with it, which is fine. To me it seems like a major change to the suspension, much more major than changing the wheel center location by 5 to 10 mm or perhaps a bit more.
Offset: it relates the mounting surface to wheel center. I don't think width is related. Width will tell you how far towards the inside and outside of the car the wheel will go, which of course affects fitment. But I believe offset single-handedly controls the location of the center of the wheel. So going wider by .5 or 1 inches does not require a change in offset. To keep the center of the new wheel in the same place, it would require the same offset.
The reason new aftermarket wheels have lower offset is so that the increase in width does not cause the inner part of wheel to rub the inside of the car. These aftermarket wheels are in fact moving the center of the wheel outwards, and thus moving the wheel away from the location the Volvo engineers designed for.
The king pin axis intersects the ground. The distance from intersection to the middle of the wheel is the scrub radius. So in this case the scrub radius depends on offset. It does not depend on wheel width at all. It's the not the wheel/tire in general that's "scrubbing." It's any amount of wheel/tire that is not centered over the turning mid-point.
At least that's how I understand it all so far!
Thanks for the info on scrub radius.

Re: wheel weigh for volvo 17 wheels? (Oldman)
Right. I agree that going to a wider wheel with lower offset changes the scrub radius. I've been trying to find out how many millimeters make what kind of difference for months, but unfortunately there are no easy, cut and dry answers. Lots of folks use 42 mm offset wheels, which is 10.5 mm change in center location and thus scrub radius, and have success. Yet other folks say changing the scrub radius by more than even only 5 mm is a bad idea. Some say don't change it at all. Tirerack.com in one communication said going to something like 45 to 48 mm offset seems reasonable. How much change of scrub radius really "hoses" the car is not clear. Does it change stuff? Of course. "Hose," meaning ruin the steering and kill the wheel bearing life? I don't know. I wish I knew the answer of badness-per-millimeter-change!
There is another option: going to wider wheel with same offset. Sure, it will limit turning radius because the inside of the wheel/tire hits the inside of the car sooner. But for S40/V50, I bet the turning radius will still be excellent even with a half inch more inside. Unfortunately, there are no 17 inch wheels with 52.5 mm offset in the aftermarket, and there are no 18x8 wheels either. Only the 18x7.5 Volvo Medea and Medusa (you can tell that Volvo does not want to change the scrub radius). Even tirerack's closest offset is, I believe, 48 mm for a 17x7.5 wheel (I forget which one).
Lowering - yeah, that's a major change beyond my limited understanding! Looks cool, though.

Re: wheel weigh for volvo 17 wheels? (Oldman)
Perfect. That's exactly what I have concluded based on asking around. There are no guarantees, but I figure the potential risk drawbacks of changing 5, maybe 10 mm of scrub radius are not horrible, and the incremental improvement in handling (not to mention looks also) from a wider wheel/tire with a little wider track is worth those risks.
