gholman12 Posted June 21, 2011 Share Posted June 21, 2011 Would my wheel bearings die in 5k miles? 10k miles? Or is it really not that big of a deal? Link to comment Share on other sites More sharing options...
TheDon427 Posted June 21, 2011 Share Posted June 21, 2011 Not a big deal at all. I had 135k on my WRX and went with 18x8 +35 and eventually 18x9 +35 for the last 3 years... which comes out to about 60-70k miles with +35 offset. There's nothing that says it'll go in 5k or 80k miles. You may increase the chance of wearing out a bearing, but it's a game of chance. It may happen, it may not.

Drift Motion Posted June 21, 2011 Share Posted June 21, 2011 in about 5 miles seriously...where did that myth of running lower offset wheels will cause wheel bearing damage come from?! spacers yes! lower offset wheels no! that offset is only medium offset anyway so you'll be fine just make sure it's 5x100 and the center bore is big enough b/c usually 5x100 medium offset wheels are for scion Link to comment Share on other sites More sharing options...
gholman12 Posted June 21, 2011 Author Share Posted June 21, 2011 True, but with an 8" width you've still got considerable tire under the brakes/bearings, 7" sticking out with a +35 offset would be torquing them considerably more, no? Link to comment Share on other sites More sharing options...
gholman12 Posted June 21, 2011 Author Share Posted June 21, 2011 Ah, wonderful. I got my info from the Wheels/Tires subsection, in the FAQ it lists the offsets for 7" width wheels as only going down to something in the low 40s. Not sure why, but good to know that 35 is fine.

Ake109 Posted June 22, 2011 Share Posted June 22, 2011 What is the factory offset anyway? Does going for a lower offset affect camber? Link to comment Share on other sites More sharing options...
gholman12 Posted June 22, 2011 Author Share Posted June 22, 2011 Factory offset is 55. Not sure about how the offset would affect camber... Link to comment Share on other sites More sharing options...
TRSCobra Posted June 22, 2011 Share Posted June 22, 2011 where did that myth of running lower offset wheels will cause wheel bearing damage come from?! spacers yes! lower offset wheels no! How do wheel bearings know the difference between, say, 5mm spacers and 5mm lower offset wheels? I keep hearing people say this, but no one can explain it.

Drift Motion Posted June 22, 2011 Share Posted June 22, 2011 when you are running spacer, the wheel and the hub are not touching the stress from the wheels are transferred from the wheel to the spacer, spacer + wheel weight --> hub it's hard to explain think of using a stick to lift something, it'll be much easier to lift something that is near the end you are holding than the end that is all the way out, meaning less torque required get the picture?

TRSCobra Posted June 22, 2011 Share Posted June 22, 2011 If you are referring to how spacers can place more leverage on the wheel bearings from moving the wheel centerline farther out from the bearing centerline, then a lower offset will act exactly the same way. Both are increasing axial loads placed on bearings designed primarily to handle radial loads... I can see how spacers could add stress to lug studs, increasing their likelihood of stretching and breaking, but I still can't see how they affect the bearings any differently from a wheel with an equal amount of lower offset. They both move the wheel out. Link to comment Share on other sites More sharing options...
Drift Motion Posted June 22, 2011 Share Posted June 22, 2011 From my understanding what matters is the distance between the wheel hub and the bearing, because I see no difference holding a low offset wheel vs high offset wheel by the center of the wheel. The weight of the wheel + tire is just there. Only difference is the amount of stress that's on the wheel spoke Am I understanding this right?

TheDon427 Posted June 23, 2011 Share Posted June 23, 2011 What is the factory offset anyway? Does going for a lower offset affect camber? No it doesn't directly affect camber. The reason why you see all of those guys with wheels that are on a 45 degree angle is because they're trying to stuff a 10" wheel with a +15 offset into the fender. The only way to make it fit is to angle the wheel in and leave it like that. Completely retarded IMO. That's the trendy super cool thing to do at the moment. Hopefully it passes soon.

No, it's the centerline of the wheel to wheel bearing distance which matters. Running a +35 or a +55 with 20mm spacers has the same effect.

gholman12 Posted June 23, 2011 Author Share Posted June 23, 2011 So what ^^ you're saying is running +35 WILL kill my bearings faster? Link to comment Share on other sites More sharing options...
TheDon427 Posted June 24, 2011 Share Posted June 24, 2011 Dude, you'll be fine. Don't worry about it. It's not a game of Russian roulette... you're worrying about "what if". There's no definitive answer. YES, it could possibly theoretically potentially wear out a wheel bearing faster than a stock wheel. However, no one can tell you if it's going to be in 10k miles or 100k miles. I see people posting this question all the time but have yet to read someone posting that it actually happened to them. I had 18x8 +35 and 18x9 +35 for years, driving 20k miles per year, with 400hp. No wheel bearing issues. You're beating a dead horse. Link to comment Share on other sites More sharing options...

No, I'm just saying that IF it did, it doesn't matter how the centerline moves, as long as it does Dude, you'll be fine. Don't worry about it. Right, I've never heard of wheel bearing issues due to offsets of wheels or spacers until I joined this forum. Link to comment Share on other sites More sharing options...
