Maximum allowable positive wheel offset?

Hey there, just joined the forum with my recent 2001 tundra purchase. I’m looking at wheel + tire combos on the cheap and have a question about offset. I’ve found that many GM alloy takeoffs are dirt cheap, and have the same width/lug spacing as factory Toyota wheels. (With more aesthetic variety)

My only concern is with offset - factory Toyota wheels have around +18 and the set I’m looking at have +31, meaning the wheel and tire will be about 20mm closer to the strut/knuckle/etc. I can’t find ANY way to calculate compatibility online, has anyone else experienced using wheels with such “extreme” positive offset?

 

Looks like the hub bore is alot smaller on a Yukon! So may not fit without modifications there.

13mm closer may be okay but really unknown until you mount up an example with intended diameter tire. Could be too close to the brakes as well. Just go measure the current space between all the main points. If any point is less than 1” today youd be in trouble.

 

yes, the hub bore is smaller. My apologies, I forgot to mention that I’m going to have a local machine shop take them up to 106.1mm to interface with the tundra.

 

Or just run a wheel spacer that’s not hub centric.

 

I’ve heard wheel spacers are bad for your wheel bearings + LBJs? Something about causing premature wear. I’ve never known anyone to run spacers though so I can’t say for sure myself.

 

I’ve run a set of 1.25” wheel spacers on my truck for the last 18 years. No issues. Many that run Tacoma and 4Runner wheels on their Tundra run spacers due to the high positive offset of those wheels.

 

Wild. I did stay up all night researching and found these:

They’re actually a hub bore + m14 lug stud + 40mm wheel spacer all-in-one?! They’re a little pricey but it was gonna cost me 2-300 to get the wheels machined anyways, plus the wheel spacer solves any fitment issues with the high offset…
