thanks

 

245/35 - No
255/35 - No
275/35 - Slightly, depends on how low you are
285/35 - Yes

Theres no need to go with a 285 on the rear if you are not making FI power. Stay with a 275 for the rear and roll the fenders. Go with a 255 front.

 

thanks for the input~
even with stock suspension i need to roll the fenders?

 

Going with a 285 isn't just about performance, some prefer the non stretched look of a tire and the extra rim protection it provides. I say go 285 and roll, its not a big deal

 

I had 285's on stock suspension and didnt have to roll. When I put my springs on then I definetly had to get my roll on.

 

I don't agree with this statement. 285s on the rear looks a lot better than 275s. Also, if you are running 10.5s on the rear the 275s will have that stretched look. IMO it's not proper fitment. Also, the offset and the tires you select will affect your clearence. Not every tire of the same size will have the same dimensions. Either way though it's best to roll.

 

with a 10.5 +18 wheel? any pics?

 

I'm not dropped yet and I have to run 285/30/19s so that I won't rub. Once I am dropped I am moving to 285/35/19s and have to roll and do a 50% cut on the inside of my fenders.

See how far out +18 pushes the wheels? They sit right over the fenders:



This is the clearence on 285/30/19s:

3/4 rear:

 

Sorry no pics at that time...however my rear was +23 or +24

 

I don't see how your post pertains to the subject then, we are talking specifically about a 10.5 +18 setup, its already widely known that a 285 will fit with the correct offset

 

Thats what I figured, I didn't think there was any way you could get away with 285/35/19 +18 without a roll

 

19 x 10.5 +17 on 285s with stock suspension WILL rub. and it will rub real bad. my tires got shredded pretty bad.

 

The rears should be +18 and the fronts +17. +17 on front with 255/35/19s are not a problem. If you were running 285/35/19s yes I agree with you. That is why I had to start with 285/30/19s.

 

BTW 285/35/19s are the correct plus sizing application. It keeps the correct inflated rolling diameter at 285. 285/30/19s are a bit shorter but I'm not having any issues with VDC.

 

so.. no need to roll my fender if i get 285 30 19 in the back?

 

If you are stock height no, but its the wrong tire size for the car, 285/35/19 is the right size. Its better to use the right sized tire and roll rather than run the wrong sized tires to prevent rubbing. You will still rub on extreme compression though, because in essence all you are doing is increasing your fender gap by using a smaller tire so the fender is further from the tire, but the width will still cause rubbing

 

A 295/30/19 would be a better tire choice for the rear.

A 275/30/19 would be the best tire choice for the front.

I have 285/35/19s on the rears with my fender rolled. I would stick with 275/35/19 if you don't want to roll and you don't plan to drop it.
