I can get a set of used 16x7 4x100 Rota JMag wheels with 205/45/16 Kumho tires. Will they fit on an xB (not lowered)?

I did not find a lot of information on JMags. According to the Rota website they seem to have 2 different 16x7 wheels in 4x 100. One with a 35/40 offset, the other with 18 offset. The owner does not know which wheels he has but they are coming off of a Civic Hatchback if that helps.

Thanks in advance

You will be fine. I wouldn't worry about it. Those are nice rims.

They are probably the ones with the 40 offset.

yes, 99.9% sure theyd be 40. i talked to someone and they said the 18 never made it to the US. something like that anyways.

yes, theyll fit. but you should go ahead and slam it so itll look better.

yup slammed is the only way to go...
1st xb with these JMags...
