lookforjoe Posted November 2, 2011 Report Share Posted November 2, 2011 I have found pegs to be very sturdy - I've lost at least 5 tires due to potholes, and not one bent peg. That last pic is impressive. That rim held together pretty well considering the impact. Could have shattered into many pieces if it were a weaker design.

gdizzle Posted November 2, 2011 Report Share Posted November 2, 2011 yeah,sliding on 3" of snow at 25mph. If it makes you feel any better Mike, I did that to a set of coveted Polaris wheels back in the 90's. :lol: Link to comment Share on other sites More sharing options...

lookforjoe Posted November 2, 2011 Report Share Posted November 2, 2011 <cough>load rating</cough> I understand, the OP had them on too heavier of a vehicle. The second set of pics, that was not the case, unless I misunderstood. Link to comment Share on other sites More sharing options...

Mike slammed his car into a curb, when you do that, things go boom. Link to comment Share on other sites More sharing options...

No. Its why rims have a load rating. Link to comment Share on other sites More sharing options...
exexpat Posted November 2, 2011 Report Share Posted November 2, 2011 I'm with Chuck 100% on this. The German TUeV often denies people the ability to transfer wheels from vehicle to vehicle, even in cases of same make, bolt pattern and center bore based on load rating. Audi A4 wheels for example will bolt up to a VW van 5x112 57.1CB but will also fail like this under load, so they don't allow it. The curb weight of the XC90 has to be >1000lbs more than an V70R and GVW much more. Link to comment Share on other sites More sharing options...
NEU Posted November 2, 2011 Report Share Posted November 2, 2011 There's a reason why XC90 wheels weigh a good 5lbs more than other Volvo wheels of the same diameter and width. FYI 19" Vulcanis only 1/2lb more then 18" Pegs. Link to comment Share on other sites More sharing options...
JVC Posted November 2, 2011 Report Share Posted November 2, 2011 I guess I'm reversing that problem, but putting heavier wheels with a higher load rating on a lighter car? SWEET! Link to comment Share on other sites More sharing options...
RBoy8 Posted November 2, 2011 Report Share Posted November 2, 2011 Was sorta thinking... could it be weight in addition to the structural design of the wheel? Vulcanis might be only a 1/2lb heavier, but maybe the structural design of it is made to sustain a heavier weight from a car? Link to comment Share on other sites More sharing options...
exexpat Posted November 2, 2011 Report Share Posted November 2, 2011 Pegs were designed for stupid high offset and multi-pot caliper clearance, that means thin spokes and less ability to take lateral stress. An XC90 with people, other weight factors and wider tires in a corner will put that poor wheel to the test. Link to comment Share on other sites More sharing options...
Che'_Moderator Posted November 2, 2011 Report Share Posted November 2, 2011 Jesus I hate when it takes these turns. Weight has almost nothing to do with strength. The two major players are design, and material. I have magnesium rims that are 18x12 and only weight 19 pounds. They are stupid light but you can bounce them off a curb. You can also have two wheels with the same material, but in general offset and back space the same the multi-spoke one will be strong as far as hard strike impacts. Without going into a ton of detail, all OEM rims are trash as fas as materials. They are very porous cast aluminum. Link to comment Share on other sites More sharing options...
