So these are the chosen fitments I have: 18x8+35 front and a 18x9+41 rears

Front wheel size: 8" +35
Fender: 8 * 25.4 / 2 - 35 = 66.6 (< 65 - OK) --->is that still ok?
Suspension: 8 * 25.4 / 2 + 35 = 136.6 ( < 155 - OK)
Rear wheel size: 9" +41
Fender: 9 * 25.4 / 2 - 41 = 73.3 (< 68 - OK)--->again! Is this ok, or will I need some rolling?
Suspension: 9 * 25.4 / 2 + 41 = 155.3 (< 190 - OK)

^^No need for all that stuff. It's simple 18x8+35 215/40 and 18x9+41 245/40 with rolled fenders. Have fun.

Do i only need to roll the back or will the front need it too? And out of curiosity, off the line with a bit wider tires, will my car post a faster 0-60 even by a tenth or is the added traction not necessary?

Yea, I would do that. 245/40 have a noticeably wider sidewall.

Decided against that. Can't find readily available all seasons in that size. 245/40/18 will do fine I hope. BTW would 225/40-18 be good on the fronts? Or would that not help.

Just look around at diff brand/model tires too. Some are tapered more than others. Any reason for all seasons?

Canada, hahaha. No but I just need a set that can last me through a few light storms and slush. Otherwise, I can always borrow my parents CRV for winter duty. The Conti DWS look very promising.

Just wondering... have you ever drove the is in "light snow and slush
before? If not, I highly recommend you get yourself a set of really really good snow tires just for winter (maybe on your stock set or something) and just get summer tires for these rims.

I don't care what kind of all seasons you are getting but, from what I have experienced and heard, you won't go that far with all seasons in even a little snow.

Hi Guys..

I am over the UK with an IS200.

Currently i have got Rays TE37 on, 18x7.5 ET42 with 215/35/18 tyres slightly strechted on them, dropped with BC Racing Coilovers, quite low must admit, the rims are all tucked in, from side looks good, but looking from the rear they are too inside the arches..

I am wanting to go the aggressive/flush look and will be rolling and pulling the arches/fenders both front and rear, so am wanting to know if i would be ok with Ichiba Spacers V2 - 15mm Front and 20mm rear??

thanks

Your best bet is to sell those and get more aggressive/ staggered offsets. I can't see how a 215 on a 7.5 could be "slightly stretched". Your wheel is too narrow and if you do get the spacers it will look funny from the back because you could actually see the width of the wheel, if that makes any sense.

That makes sense fine, but as a temporary set-up, as long as it works, am happy for now, as the car looks weird with the wheels tucked too far in, i got these wheels for free so can't complain...
Plus it is illegal for wheels and tyres to be wider than the car over in the UK, the car can be taken off you.. if the police ain't got nothing better to do that is..!!

It will have to do untill i get some cash saved up for new wider wheels.. cash is strapped up due to house purchase.. hopefully by summer will be able to source some.


Thanks Kraven

So based on the equations given, the most aggressive offset for the front with a 8.5" is right around the +42 and a 9.5" in the rear of a +52? Is this correct?
I'm really just trying to go the limits without having to do any fender work. I don't mind bending out the liner, but again I really don't want to roll/full my fenders. I'm really just trying to go as flush as possible.
It would be great if someone can clear this up, so I can go ahead and order my $3800 wheels.

You don't want to roll the fenders but you are going to spend $3800 on wheels??..lol. Anyway, I have 17x8.5+30 in the front with a 215/45 (rubs sometimes). Honestly, if you want to be "flush", roll the rear. If it's done corectly, you wouldn't even notice. Good luck.
