I have a 2016 Honda CRV, with a current wheel offset of positive 45mm. I have a chance to get nicer wheels, all the same specs except they have a 50mm positive offset. Do I need spacers, new lugs, etc? Or is there enough room to lose the 5mm?

Go to https://www.wheel-size.com/ and enter your OEM wheel and tire size and new wheel/tire size.

It will show you the impact on clearance between wheel/brakes and tire/fender.

<.2” is a very small difference. Are you positive the new wheels the same width? I doubt there is such thing as .197” thick spacer. Lug nuts depends on the new wheels.

Bolt a new wheel on and spin it. Are they different (used) wheels or brand new wheels. If it’s a new wheel AND you mount a tire, you bought it.......that’s the way I understand it.

Thanks for the help. The wheels are from a 2016 Acura ILX, OEM. I have found several 5mm spacers, but I am concerned about replacing the lugs. While it doesn't seem to be a huge deal, I want to make sure that this these fit. I'll keep looking into it, but I am concerned about the "scrub radius" being changed by -5mm. It doesn't seem like a big deal, but I am sure it will turn into something.

I would be shocked of 5mm or 2/10th of an inch made any difference at all.
Looking forward to seeing pictures of these rims fitted to your CRV.

Ya 5mm offset change won't hurt anything. But for advise, usually try to stick with same or LESS positive offset, not more. 5mm should be fine just don't go wider tires.

Yeah Buddy! Got the new Acura ILX rims, installed, and they look great! The 5mm offset difference was not a factor. I appreciate everyone's help

The CRV looks nice with the Accura rims. Good choice.

I'm currently looking at essentially the same situation. Just ordered some Accord rims for my 2014 ex-l V. Like you, the offset is what concerns me (I'm pretty sure the rim will fit clearance etc).

I know you said you just went with the new rims and didn't do the offset ring? Have you noticed any problems? Steering or handling? I too would be going up by 5mm, unless I used the rings which are arriving today

Maybe you were told the rings wouldn't be usable without new studs etc? Would luv to hear as will be going through the same experience in a few days.

Does 5mm make a difference? Wow, let me tell ya. I've spent so much time reading what is said in that regard. Or on the phone with tirerack, goodyear, disc tire, etc.

It' seems pretty much all I've talked to indicate, "it's not a problem". But there are some places you read and they indicate the potential for additional wear and tear on wheel bearings, ball joints, etc... even due to a diff of 5mm in offset.

The explanations are basically mechanical engineering specific (which my software engineering background doesn't qualify me for) and contact patch / scrub radius, bearing pressure points (uneven pressure due to the change in offset), King pin Axis and the affect on ball joints, etc etc.

Here's my current thinking; if, when I ask someone telling me that the 5mm will make no difference, and I request that guarantee in writing, and they refuse... then I want to use the 5mm spacer.


What do you think? other than, wow what a time consuming pain in the arse this all is

If I'm understanding positive offset correct (presuming no change in wheel/rim widths), when the positive offset number goes up, the wheel/tire move closer/inward to the car.......no?

It is confusing, if the offset is positive, and the number goes down, then the tire and wheel will be father out.

The key thing to remember here is, if you want your tires to be the exact offset as the oem, then (obviously) the same offset will work. In addition, if you get new rims with offset that is less, there's nothing you can do to make it the same as the oem offset.

But, if you get rims with a higher positive offset, then a spacer could be used. I highlight the could in that using a spacer is somewhat problematic in itself. Hub centric? are the wheel studs long enough? how do you know? Do you need a hub centric ring?

I'm just reading now that on the V's m12x1.5, I think you'd need 8 full turns, plus 4 more, to safely use a 5mm spacer. 8 is supposedly the requirement for that stud, the additional 4 would then be used for the spacer... it would work.

If the studs aren't that long, one would need to get longer ones.

It's all a pain, I swear. These wheels better look damn good, or am a gonna be pp'd.

+/- 5 mm is not an issue. It has no real world effect on wheel bearings or tire wear.

I installed aftermarket wheels that have 5MM more positive offset (50MM vs OE 45MM) and are 1/2" (12.7MM) wider than the OE wheels. No spacers, no hub rings, no issues, everything is good, smooth as silk. New lug nuts came with the new wheels.

...........Just ordered some Accord rims for my 2014 ex-l V.............

What year Accord rims did you order????

 

[Azitlies]

Not ordered, ebay, I think they are off a 15 to 18 Accord. They are oem size, 17 but 7.5 width vs the oem 6.5. Want to use same tires etc. All I really want to do is change the 'pinched' look. It's not a truck, imho.

+/- 5 mm is not an issue. It has no real world effect on wheel bearings or tire wear.

I'd be interested in what you base that on? your experience, and what everyone else says?

I get that and understand, I do. But, anecdotal evidence isn't factual. And because some engineering sites indicate possible early failure of steering parts... then it becomes a tough decision, for me anyway.

I'm just checking now, looks like even a 5mm spacer would require longer studs, and it looks like it's a nightmare to install longer studs on a CRV. It may be I'll more or less have to live with the 5mm larger offset, if I want to keep the new rims...

Well, on the plus side, I don't drive much! lol

Yeah looks like I may be doing the same thing, essentially. Mine are 1" wider and assuming that all fits, no rubbing or hitting shock or caliper...

Will probably just have to live with the change in offset. So the offset change will move the wheel / tire in by 0.2, but the width diff out side would be 0.5, should look fine.

The tire shop will tell me more re the spacer, but from what I can tell, studs aren't long enough, I'd bet they refuse to use the spacers for safety reasons.

Let's not go there. This will turn out really bad.

 

[Azitlies]

That's called anecdotal evidence. I don't consider it bad, or consider it worthless, I just don't take it as fact. It may be fact, but it's not proven to be if the only evidence is 'a bunch of people say that', or even 'my experience is' (i.e. anecdotal).

You will do just fine in this forum.

You've got this.
