Default Tire size question, Luke please help!

ok I got a two 245/45R18 tires sitting at my house, actually just mounted one on one of my 18s. I was wanting to run the 245/45R18s in the front and I'm looking at getting some 255/45R18 in the rear, but I'm kinda worried of the AWD system.

heres the Overall diameters of the tires.

245/45R18 = 26.7"
255/45R18 = 27"

Is that going to make enough difference to ruin my AWD?

Oh here is also a picture of the 245/45R18 mounted on my 18" Rota Subzeros and on my car.



The car is about 3 inches lower than stock, maybe a little higher. I'm definatly going to have to raise it about a half inch or so. But I love how it stuffs the fender like this.

Aren't those about 10% bigger than stock? When your speedo says 65, you're really going over 70! Why not stick with 245/35 18 all around? Do you have 22b fenders?

Hey stop smoking the cheap crack. The GC08 can only handle a 215 max width. Also your tires are 2 tall in the sidewall. With 18's you should be running 35 series tires. There is no way in hell you can get those tires to work on your car unless you get 22B fenders.

Well they must be wrong, if you look that is the 245 tires tucked into the fenders and yes I can turn the wheel. I do need to raise it up just a tad bit though.

Also those are the stock fenders, there not the 22b fenders.

I also know of the speed difference to, that doesn't bother me anyways since i never even look at the speedo when I drive. Well I do but most of the time I just drive.

I did have 215/35R18 tires but I hated the look of them, looked like rubber bands on my rims.

Heres another pic



Like I said I can turn the tire, now this is turn all the way, the tire is hitting the fender and I do need to raise it to keep this from happening. Other than that its not hitting anything else. Also yes my fenders have been rolled.

Also I am do fender flares too and will be pushing the whole rim and tire about 1 inch outwards.

Oh also I'm running 225/50R16s on my stock rims so the 215 width is not the max on the gc8 body style.

I mean yes it is if you do not plan on rolling your fenders and keeping it stock height and everthign but my has tons of suspension mods and the 225 tires are not doing enough, i need wider tires.

I would suggest the same size for the rear .... the AWD system used by Suby does not allow for variations in tire diameter like some other AWD cars .......
