Wheel fitment question 20x10

[NEWROCK33]

Newbie here. I have a set of custom-built 20x10 ET5 wheels (6x139.7, 100.5mm bore). Will these wheels fit without issues? And what tire size would you recommend?

Thanks in advance!"

Recommendation... remove one wheel and place rim on with lug nuts as a dry test run.
Just FYI. The H3 has hub centric rims.
Tires are what ever flavor you desire.

The H3 has a 100mm hub center, so the 100.5mm bore should fit. However, you don't mention the back spacing; you need to go with a max of 5.5" backspacing. Not a fan of 20" wheels for off-road, so I have no recommendations for tire size.

different vehicle, but a guy i was recently talking with was having a weird vibration at a specific speed (67mph on his car) no matter how many times he balanced his aftermarket wheels/tires. turned out his wheel center bore was ever-so-slightly too big (.5-1mm ish), so he wrapped a thin aluminum strip around the hub before reinstalling the wheels - cured the vibration.
