Question/concern about hub centric wheels...

I am coming from Jeeps, where all the wheels are lug centric, so I never had to think about this...

Anyway, I ordered some Method 705's that are supposed to be specific to the Tundra. The spec for the hub bore on the wheel is 110.5mm.

I come to find out that the earlier 2nd gen Tundras have a 110mm hub and the 2014-21 Tundras have a 110.5mm. Why Toyota would change it I have no idea. But it turns out every wheel maker under the sun just swapped over to making 110.5 for ALL Tundras now.

I test fitted one of my new wheels and sure enough, there is a tiny gap around the hub and the wheel can move slightly in any direction.

To me this seems like a problem. This seems like I am going to be putting the weight of my truck on my lug studs when the truck is designed to have the weight on the hub.

I saw a website somewhere that basically said if the hub measurements are "within 0.5mm" then it is ok. But that doesn't make much sense to me. A wheel can't be hub centric if the hub isn't touching the wheel. A tiny gap is still a gap.

I know, there are going to be a lot of guys here who have been running their 110.5mm hub wheels on 110mm hubs without issue for years and years. But there are also people who have smoked for 60 years without getting lung cancer. Doesn't mean I'm going to be that lucky. Besides that, I am building this truck to actually use off-road, and no matter how careful you are offroad, things happen, rocks roll and slip, and your truck drops 5 feet and lands hard on a wheel at an angle. Don't want my lugs sheering off.

So what would you do?

There aren't any wheel centering rings made for a half millimeter gap. I really don't want to return the wheels and try to find something that has a 110mm hub bore, which I doubt I would find.

The only solution I can think of is buying a set of custom wheel spacers from BORA. I can get them made to 110mm for the hub, and 110.5mm for the wheel. The only issue there is I would need to keep the spacers as thin as possible, which would probably mean changing out my lug studs to longer ones, which opens up a whole new can of worms since nobody makes an extended 14x1.5 lug with a 16.5mm knurl.. Except for one guy on Ebay..

 

For a first gen, I bought Bora and Spidertrax in different widths for test fit before ordering steel. They both had more play than my Methods to OEM hubs, less in Bora. Both were pretty tight against the methods once installed. Not sure if that helps, but also not sure .5mm will be taken up by spacers.

 

07-21 all have 110.1 hub bore.
Simple as that.

 

You should be fine. That gap is so small that it's not an issue. The correct lug nuts will center the wheel.

 

Get some correct lugs. You’ll be fine.

I’m running methods that aren’t hub centric. Been on my truck about three years-zero issues

 

Yes, I am aware of that. The issue though is that if the lugs are centering the wheel, it is not hub centric and is therefor a weaker mounting method.

 

Yes, I know that lug centric wheels can be and have been run with zero issues. However the truck is designed to be hub centric for a reason and under hard use a lug centric mounting method is inferior to a hub centric method and is more likely to fail, even if it hasn't for most others.

 

It’s not difficult.

SCS Ray10 wheels 18x9

 

My original ‘08 TRD wheels and my ‘17 TRD wheels fit the hub pilots of my ‘08 exactly the same. A little bit of wiggle room when clean. Probably .010- .015”, but I’d have to admit that’s a WAG.

I really don’t know where the discrepancy is coming from, unless the rotor bores are 110.5mm (the hub pilot does step up a wee bit) as I haven’t ever attempted a precise measurement. But I do know that OEM 2nd and 2.5gen wheels fit the same.

Meaning that if aftermarket wheels fit one, they will fit the other.
