16 x 7. To go ET40 or ET45 ? - Toyota Yaris Forums

I dont get it!

+38 rims have lesser offset than +45 , which means..... the +38 is being pushed out more towards the fenders. I dont get it, when u say +38 wont rub, but +45 will, unless u are talking about rubbing on the inside of the tire against the suspension components.

Please clarify. Thank You.

An extreme example is illustrated below... sorry for the 1 minute drawing.

By the way, large orange font, whats your ET ? You rub a little, so I figured if I could give it a bit more positive offset, it shld do the trick.

Thats correct, +45 may rub on the inside, and +38 nearly rubs on the outside. This is why it is recommended to get something between these measurments using them as a minimum and maximum. For a 7 inch wide wheel I would go with a +38 to +40. For a 7.5 inch wide wheel I would go with +42 or +45.

Keep in mind were talking about a diffreence of 7mm from minimum to maximum offset, which is not much. If you don't know, 10 millimeters = 1 centimeter, and 7mm = .27 inches, so about 1/4 inch difference.

I have +40. and I rub slightly on the INSIDE on the front. +38 should give you a bit more clearance, but you will probably need to roll your rear fenders a bit because if you have the car fully loaded (4 people) the tires my rub on the OUTSIDE. My tires just clear but a +38 would rub.

Thank You. I've been confused for the longest time. To play it safe, I might just go for the rarer 195/50R16s
