How would a 17x7 wheel with a 40mm offset fit? I'd like it to be flush with the fender if possible.

It'll be kinda sucked in...i've got 17x7.5 with a 35mm offset and it still is kinda sucked in the rears. Not by a lot but if you're looking for a flushed look, you'll need like a 30-32mm offset

it'll be really sucked in. I don't mean to be rude, but have you looked at the original post? this isn't the first time you've asked a question and the answers are already there.

ok ive read most of this thread and am still stumped with offsets lol im looking to go with a wider rear and thinner front tire looking at

whats the widest i can go in the rear????

you could probably get away with the 8.5" with the 35 mm offset in the rear. in the front, you'd probably want a 7.5" with about a 30 offset. you could use the 7.5" with the 35 mm that they have listed in the front, but it'll be a little sucked in.

Are you people out of your mind???

It does not matter what size wheel you have you do not change the offset.

If you do you would change the steering behavior because the tires no longer pivot at the center when you steer and you risk the tires hitting the wheel well.

???

Offset is directly related to wheel width. Not changing it when you use a wider wheel is just plain ignorant. The difference in steering behavior is only a factor with drastic offset changes, not minor changes as have been mentioned in this thread.

If you need help understanding this concept I'll try and teach you.

"In a nutshell you need an offset as close to the vehicles original wheel offset as possible"

yeah, if you will be using the same width wheel as stock (7 inches) and don't mind it being just as sucked in as the factory wheels, then go for the factory offset. but if you want wheels that are a different size than stock and/or want them to look good, you need a different offset. these aren't very drastic changes in offset that were talking about anyway.

I've worked at 2 different tire shops over the last 13 months and I've put numerous sets of rims with different offsets than stock on many different cars and never once had them come back and say their car doesn't steer. any and all affect on steering can be fixed with an alignment.

The car looks better flushed, I have 7.5 with 32 offset and it does look much better but its still tucked in a bit. The rear you can run wider than the front but only problem is you either can't drop it that low or you gotta roll the fenders. Reason being is the lip of the rear fender is wider than the front. The front barely has any lip at all.

Okay, I'm kinda understanding this and still a bit lost.
I am currently looking at a set of rims that are 17x7 with a 35 offset. Tires are 225/45/17.

So a 10mm spacer in front and 15mm spacer in rear for the flushed look? Hope that is correct. If not, please help me clarify this.

Ok. So i finally found someone out in Cali that sells Rotas. Going with gunmetal SDX. The only size available is 17x7.5 5x100 and +48 offset. Will this work. I'm planning on lowering the car 1.5" with eibach sportlines and kyb shocks. Will this offset work for my car. What will i need to make it work?

all depends on the width and offset, my 7.5" and 32 offset is still clearing the fender rim. If you are not thinking of dropping the car too low, you can get much wider rims. Local shops will be able to calculate that for you for the celica specifically.

meh, I work at a "local shop" and I've looked the celica up on the computer before. I can't remember exactly what it said we could fit, but it was wrong. we could fit way bigger than what it was saying.

I can't remember, but I'm 90% sure the stock wheel is a 15x7 with a 42 offset. so, using this calculator http://www.motegiracing.com/techzone/Offse...tor/offset.html here's what will happen with those 17x7.5's:

Your new wheel will have the following characteristics:

The clearance from stut housing to the inside of the wheel will be 12mm LESS
The outside edge of the wheel will extend to THE SAME point as the stock wheel

so, take a look at your stock rims and see if you have half an inch (12.5mm) clearance between it and the strut housing, and then think if you want them to be just as sucked in as the stock rims...

EDIT: ok, stock rims actually have a 45mm offest, so the 17's will actually be 9mm closer to the strut and stick out 3mm farther than stock

i bought 17x7 offset +48. im waiting for the tires and tuner lug nuts. i post pics when its done

After reading all this stuff. I'm still so confused. I wanna get new 17's, and i want all the tires to be flush with the possibility of not having to use spacers. Can anyone help me out? I do not have any lowering mods, and I also want wide tires.

Thanks for the reply. I appreciate ur knowlege in wheels, since idk much about them. Cool offset calculator. So according to this i would want atleast a 9mm spacer to keep the wheel away from the strut housing? Is this right? If not what will i need to do to make it work? Thanks again.

not saying that you'll need spacers. Only that the wheels you want to get will be 9mm closer to the strut tower than the stock wheels. So, as long as you there is more than 9mm clearance between the stock wheels and the strut tower, than the wheels will fit. They will not be flush, but they'll work. If you want them to be flush, use the offsets listed in the original post, though I think those are off by a couple mm.


I used 17x8 with a 35mm offset on my car and they were about as close to flush as you can get without running staggered, or with spacers in the rear. I personally ran 225/45/17 tires, but I'm pretty sure 235/40/17 and possibly even 245/40/17 would fit with these wheels.

235 and 245 will definitely fit on a 17x8 wheel. I have 235's on my 17x7
