What kind of offset should I look for?

[The Lox]

I have found a couple Rota Brand Wheels I like. The first choice is 16 x 7 +45mm offset with 5x100 pattern. Any reasons why they shouldn't fit?

They should fit, no problem. I think the stock offset is +38mm. Naturally you'll need hubcentric rings.

My snow tires/wheels don't have centering rings and i've delt with a "out of round" situation all winter.. DOH...

Most aftermarket rims require hubcentric rings. They're only about $15.00 a set.

I will mention that the +45mm offset might be a little nicer than the +38mm offset of stock. I replaced my wheels with stock parameters - 17in with 38mm offset only to be disappointed with the overall look.This offset is the exact same for the Matrix. The difference? The Matrix doesn't have the additional fender cladding that sticks out. So when the wheel is mounted, it still feels recessed into the wheel hub. Ideally (to me), it would be flush with the cladding. I don't know what that offset would then have to be though.

The last couple sets I have swapped have been stock take offs from other vehicles, so that might be the reason I am not used to these rings. I am sure whom ever sells the wheels I buy will be able to help...

Offset is very important. Recommended for a Vibe is a high offset between 35-42. The wrong offset can cause rubbing problems when the suspension is compressed or the wheel is turned. You can get spacers or hub rings to solve the problem but it is best to meet the required specs

If a +38mm offset is too far inside the wheel well, then a +45mm is going to be farther inside that wheel well by another 8mm . Take a look at the 17 inch OEM Vibe wheel with the 215/50 tire. I tried a +42 mm offset 16 inch alloy with stock sized 205/55 tires, and they were tucked in noticeably more than the OEM steel +38mm .I'm trying to find the same fitment you are with a 17 inch wheel/tire combination. Also would like that flush wheel and cladding edge look. We need more input from all the GV members!!!

The wheels/tires I got put on my vibe at 18x7.5" with a 38mm offsest. Tires are 235/40/18. The front wheel edge sits in the fender about 0.5" from flush. However, the rear was still 1.5" inward from flush. So, I got 1" spacers to make up the difference in the rear, and the look is much, much nicer now. The front and rear "offsets" look uniform. The 1/2" in the front and in the rear is not completely flush, but I don't have any clearance issues during turning or during suspension compression. However, now I have to clean my car more often due to the dirt/tar/debris that get thrown up from the newly exposed tire surface. Maybe I need some mud flaps

Good info sj... thanks. A picture or two would help... especially down the side of your car from the front and rear. Half inch inside the edge of the cladding is just about right. I guess you got that measurement at the top of the wheel well, the place where it's out farthest. Any farther out and you would really get a lot of splash debris along the side of your car. I have mud flaps... but they don't stick out very far. They do help a little. I'm starting to think that a +38 to +40mm is about right with a 7.5" wide wheel.
