Like the title says, i searched but couldn't find an answer for this question.
I have 4 brand new 245/45/18 and want to know if i can mount these on the stock coupe 18's without any issues.
I have an 03 coupe.

Thanks.

I wouldn't do it, too tall for the front, would look way bad.

No. The taller tires in the front will **** up your speedometer. But depending on the tires, I might buy two off you

You can use that size but you'd be better off with 245/40X18's....

Thanks for the imput guys, i would love to trade ya for 2x 225/45/18 but i'm toronto. they are yokohama advan s4, all with stickers.
As for looks, i didn't think you can notice the difference between a 225 and a 245 without looking very closely.

I have 245/45/18's on for winter use. The front is def a little tall, but it works for winter use in my case. I probably should have gotten 225/45, but I already had new 245/45's and wanted to be able to rotate them front to back. They do cause some ABS chatter.

I have 245s all around, bought it that way, looks good and runs fine

i know the front is a little too tall but i think i might end up using them, just because i already have them. It worked for some of you guys so i guess it will be fine.

can u or anyone post pics of tires 245/45 all around on the g wit stock 18 rims? i wanna do the same too. i wanna be able to rotate to get more life out of the tires.

^I've never seen anyone do this before so don't think there's any pics out there.
If you don't have the cash to buy the tires... I suggest you not get a rear wheel drive car.

I ran 245/45/18 all around and it looked great!! The car actually handled really well with this set up too. Speedometer wasn't off to my knowledge and my VDC never acted up.

I don't have any pics but it filled in the tire gap perfectly with my drop so it looked really good and proportionate.

245/40/18 is better no?

245/40 is probably a little better, yes. Depending on your drop, 245/45 might be a little too tall for the front, I know that in my case I do rub the liner on big bumps/dips while at speed.

I can try to snap some today as I still have my OEM winter setup on with the 245/45 all around.

^^yea that would be great thanks. i like the 45 profiles becus of the extra cushion too

I definitely notice more roll and bounce, but I'm not driving hard during the winter so no biggy. here are the pictures I snapped yesterday (sorry for phone pictures):





I'm glad that it's getting to be about that time I take these off.
